Vacuum hot water boiler is a common heating boiler, commonly used in hotels, shopping malls, residential buildings and other places, and provides a great help for normal heating in winter in cities in southern and northern my country. In recent years, the utilization rate of vacuum hot water boilers in various industries has gradually increased, and has been used and affirmed by many users. So, what advantages can the use of vacuum hot water boilers bring to users and friends? Let Zhengzhou Fangkuai Boiler Factory tell you the answer.

1. Vacuum hot water boiler has good energy saving effect
       The vacuum hot water boiler adopts excellent vacuum hot water boiler technology. The boiler operates in a vacuum state, has a low boiling point, and releases more latent heat after evaporation, thereby improving thermal efficiency; the boiler also has good heat transfer performance, and waste heat is installed in the exhaust gas channel The recovery device has a thermal efficiency of more than 107%, and the energy-saving effect is evident.

2. The vacuum hot water boiler has higher negative pressure operation safety
       The heat transfer medium inside the vacuum hot water boiler is always in a vacuum state, and there is no danger of expansion and explosion of the boiler body. The vacuum hot water boiler launched by Zhengzhou Fangkuai Boiler Factory also has an automatic protection device, which has incomparable safety compared with other boilers on the market.

3. The vacuum hot water boiler is anti-corrosion and non-scaling, and the service life is longer
       The heat exchanger of the vacuum hot water boiler is made of stainless steel. The heat medium water injected at a time will not corrode and scale in a high temperature environment. It can be used for 20 years. The service life of the boiler is almost two times the service life of an ordinary boiler. Times.

4. The vacuum hot water boiler is small in size and easier to install
       The vacuum hot water boiler adopts modular design and is equipped with high-performance heat transfer elements. The overall volume is reduced by more than 40%. It is very convenient for transportation and installation.

5. The use of vacuum hot water boiler is exempt from approval and the procedures are simple
       Since the vacuum hot water boiler operates under vacuum conditions, there is basically no safety hazard. The pressure-free special equipment is submitted for approval without annual review. The boiler operator does not need to hold a license, which can save the trouble of going through various procedures.

After the vacuum hot water boiler was developed and manufactured as early as the 1970s, after numerous optimizations by numerous technical engineers, it has now reached a good operational state, whether it is operating efficiency, service life, or overall quality. As a result, it has also been recognized and loved by more and more users. So, what aspects should be paid attention to when selecting the vacuum hot water boiler? Let Zhengzhou Fangkuai boiler manufacturer tell you the answer.

As with traditional boilers, when choosing a vacuum hot water boiler, in addition to understanding the boiler quality and procurement costs, you also need to pay attention to the following factors:

1. Fuel for vacuum hot water boiler
       When choosing a vacuum hot water boiler, the first thing to consider is what fuel to burn. At present, the vacuum hot water boiler can use both natural gas and light diesel. In combination with my country's current environmental protection policies and ease of use, Zhengzhou Fangkuai Boiler Factory recommends that the majority of enterprises use natural gas as the fuel for vacuum hot water boilers.

2. Evaporation capacity of vacuum hot water boiler
       "Evaporation capacity" can also be referred to as the boiler's evaporation load, that is, the steam or hot water required by the user. Before purchasing a vacuum hot water boiler, users and friends must have an understanding of the amount of hot water required by the boiler, so that the boiler with suitable capacity can be selected when the boiler is selected.

3. Heat exchanger of vacuum hot water boiler
       Compared with the traditional hot water boiler, the vacuum hot water boiler has a heat exchanger inserted inside, and the choice of heat exchanger needs to be determined according to the user's boiler. It is divided into three types of heat exchangers, which have different uses for different needs such as heating, sanitary hot water, and process hot water. You can choose the corresponding heat exchanger according to the needs of purchasing a vacuum hot water boiler.

Pressurized hot water boilers are one type of hot water boilers, just like atmospheric hot water boilers. The difference is the internal pressure of the two types of boilers. The interior of the normal pressure hot water boiler is at normal pressure, and its safety is relatively high. It is often used for heating and heating in places with a large flow of people. The inside of the pressurized hot water boiler is under pressure and can output hot water with a higher temperature than the normal pressure hot water boiler. What are the advantages of using a pressurized hot water boiler? Let Zhengzhou Fangkuai Boiler tell you the answer.

1. The price of pressurized hot water boiler is cheap
       The market price of pressurized hot water boiler itself is not high, and in recent years, the price of gas fuels such as natural gas has also decreased. Generally speaking, the cost-effectiveness of using pressurized hot water boiler is still very high. In addition, the utility model pressurized hot water boiler launched by Zhengzhou Fangkuai Boiler Factory has high durability, simple and convenient maintenance, and more economical use.

2. The operating efficiency of pressurized hot water boilers is relatively high
       The layout of the pressurized hot water boiler is designed as a three-pass wet structure. The heating surface is much more than that of the two-pass boiler. The heating surface is more active and the heating is more uniform. At the same time, a flue gas condensation recovery device is installed at the end of the boiler, which can be very good. Controlling the high temperature of the exhaust gas from the boiler greatly improves the efficiency of the boiler.

3. The operation of pressurized hot water boiler is safer and more stable
       The pressurized hot water boiler produced by Zhengzhou Fangkuai Boiler Factory will be equipped with high temperature alarm system, overpressure alarm system, water shortage alarm system, leak alarm system, fire protection system and other safety accessories when leaving the factory, making it safer and more stable to use.

4. The pressure-bearing hot water boiler has a small volume and a small floor area
       The pressurized hot water boiler of Zhengzhou Fangkuai Boiler Factory is equipped with a fast loading structure. The bottom of the whole boiler is made of high-rigidity materials. After several performance optimizations, the overall volume is small, which is more convenient for installation and transportation, and is more convenient for space. The requirements for use are not high, and it is suitable for use in various environments.

Gas-fired hot water boilers are used in heating and heating fields in many situations, such as airports, hotels, residential buildings, shopping malls and other places have their presence. I believe that many users are very concerned about the hourly air consumption of the boiler when purchasing a hot water boiler. Zhengzhou Fangkuai Boiler Factory uses a 2 ton gas-fired hot water boiler as an example to explain the hourly gas consumption data of the boiler.

Under normal circumstances, the gas consumption of a gas-fired hot water boiler is affected by the layout of the heating surface, the water capacity, and the boiler heat preservation effect. There is a calculation formula for gas consumption: boiler gas consumption = pressure steam boiler output / thermal efficiency / natural gas heating value. Then the hourly gas consumption of a 2-ton gas-fired hot water boiler is about 130-150 cubic meters.

Many users do not understand why the difference in gas consumption is so large. This is mainly due to the influence of boiler thermal efficiency and natural gas heating value. The higher the boiler thermal efficiency, the lower the gas consumption; the higher the natural gas heating value, the gas consumption will also vary. It is lowered.

Therefore, when you use a gas-fired hot water boiler, if you want to reduce the gas consumption of the boiler, you can choose a boiler with high thermal efficiency and relatively better configuration, and choose to use natural gas with a higher calorific value as the fuel. The gas consumption will be reduced, so as to achieve the purpose of energy saving and money saving.

This also indicates that when purchasing a gas-fired hot water boiler, we must pay attention to the boiler’s operating cost in addition to the boiler’s procurement cost. The main factors affecting the operating cost are the boiler’s gas consumption, thermal efficiency, and heat preservation effect. And other factors.

Gas-fired hot water boilers are used very frequently in our daily lives, and domestic heating and hot water supply are inseparable from it. For boiler equipment, good and effective maintenance can not only improve the use efficiency of gas-fired hot water boilers, but also extend its service life; then what effective methods should be used for maintenance?

1. Pressure maintenance
       This kind of maintenance method is suitable for boilers that are out of service but short-term maintenance does not exceed one week. You can drain all the water in the boiler first, then clean up the scale in the boiler in time, and re-add qualified softened water; use a warm fire to heat it regularly to keep the water temperature in the gas hot water boiler at ten degrees in summer In winter, it is guaranteed not to freeze; water must be supplied to the boiler regularly to keep the pressure in the boiler at a normal value to prevent air from entering the drum.

2. Wet maintenance
       This kind of maintenance method is suitable for gas-fired hot water boilers that have been shut down for no more than one month. After stopping the boiler, the boiler water should be drained according to the specified time, and the impurities inside should be cleaned up; secondly, all inlets and valves should be closed to completely separate it from the running boiler; and the prepared mercury should be used. Alkaline protection solution is put into the boiler; during the entire maintenance period, the oven should be regularly used with a low fire to keep the heated surface dry.

3. Dry maintenance
       Dry maintenance is suitable for gas-fired hot water boilers that have been shut down for a long time. It is also necessary to drain the water and remove impurities. Secondly, it must be completely isolated from the running boiler; use an appropriate amount of desiccant to absorb moisture in the boiler, and at the same time, the desiccant must not be in direct contact with the heated surface of the boiler ; Within one month, it should be checked whether the desiccant will cause corrosion in the boiler.

The above is the method of maintenance of gas-fired hot water boiler from three aspects summarized by the Zhengzhou Fangkuai boiler manufacturer. The boiler factory also emphasizes that regular inspections should be carried out when the boiler is used, and special attention should be paid to the corrosion of the boiler. Ignoring the problem of corrosion will have unpredictable serious consequences.

The condensing gas-fired steam boiler is based on the gas-fired steam boiler with a new condensing device, which can increase the thermal efficiency of the boiler to more than 90% or even 98% and other very high data, saving users a lot of fuel costs. So, what matters should be paid attention to during the operation of condensing gas steam boiler? Let Zhengzhou Fangkuai Boiler Factory tell you the answer.

1. Correct cleaning and treatment of the boiler
       To achieve cleaning and disposal during the operation of condensing gas-fired steam boilers, we must first ensure that the efficacy and composition of the acid-washing slow-release agent can meet the corresponding use effects. Among the products designed by our country’s fully premixed condensing boiler manufacturers More need to ensure stable cleaning ability and better cleaning standards.
       Therefore, in the stable operation of professional condensing boilers in our country today, it is necessary to pay attention to the corrosion rate and corrosive materials and master reasonable testing methods to ensure that the cleaning of the circulating pipelines is smoother to ensure this kind of condensing boiler with more stable cleaning quality The stable use and dust removal effect.

2. Pay attention to the emergency warning and timely shutdown of the boiler
       In the daily use of condensing gas-fired steam boilers, only by ensuring that the corresponding dangerous failure factors are understood and the basic system is implemented in a timely manner can the condensing boiler play a better role, and the condensing boiler needs to pay more attention to its operation during operation. Existing dangerous problems, to ensure that its own disposal more satisfies the demands of daily applications and safe operation.

Zhengzhou Fangkuai boiler manufacturer reminds everyone that when using condensing gas-fired steam boilers, attention should be paid to the specific status of the daily operation of the equipment, and reasonable maintenance can avoid potential hazards that may be encountered as much as possible.

In recent years, condensing boilers have been favored by more and more users, and the frequency of use is also increasing year by year. It can be said that the advantages of condensing boilers are recognized by more and more users. However, for users who are new to boilers, condensing boilers are still a relatively novel type of boiler. Zhengzhou Fangkuai Boiler Factory will explain to you what type of boilers condensing boilers are, and what advantages they have.

The condensing boiler is based on an ordinary boiler with a new condensing heat exchange device. Through this device, the thermal efficiency of the boiler can be increased by more than 10%, reaching about 80%. The thermal efficiency of the condensing boiler of Zhengzhou Fangkuai Boiler Factory is even higher. Up to 98%.

In addition, the heat exchanger used by Zhengzhou Fangkuai Boiler Factory for the condensing boiler has relatively high material requirements and has a strong anti-corrosion ability. Since the discharged flue gas will contain a large amount of acid gas such as carbon dioxide, when the flue gas is converted into condensed water, it will have varying degrees of acidity. The long-term contact of traditional converters with condensed water will cause its surface to be corroded and scratched. The changeable condensing boiler converter is made of very stable materials, reducing component corrosion damage and Zengcheng use time.

The energy-saving benefit of the condensing boiler is also very high. The temperature of the low-temperature fluid inside the condensing boiler can reach a very low level, which is good for taking away and reducing the flue gas. The water vapor condensate also increases the display heat and latent heat that can be recovered There are also more and more, so the efficiency of the use of heat energy of the condensing boiler is also greater.

Winter is the peak period for using hot water boilers. Most northern cities use hot water boilers for heating and domestic water supply. However, Zhengzhou Fangkuai Boiler Factory found that many heating companies ignored the antifreeze work of boilers in winter, which led to failures and losses. Let’s talk about what protective measures should be taken when hot water boilers are used in winter.

For the hot water boiler system, the temperature is low in winter, the first thing to do is to prevent freezing of the entire system of the boiler. When the temperature of the water tank is low, pay attention to prevent freezing and cracking. Compared with outdoor boiler equipment, this also shows the boiler The advantage of the room.

Secondly, when the hot water boiler system or auxiliary equipment encounters a failure, it is necessary to stop the system, check and eliminate the problem, remove the water and wastewater in time, and open or close the valve according to the specification.

There is also the piping problem of the hot water boiler. It is necessary to do a good job of anti-freezing of the cold water pipe to avoid freezing, which affects the overall operation of the boiler system. In addition to regular inspections of the steam boiler, the operating conditions of the auxiliary equipment of the system should also be checked to ensure that the boiler can also provide heating and heating normally in winter.

The scope of use of steam boilers is very wide, so it is also one of the more frequently used ones on the market. However, in the daily operation of the steam boiler, certain problems and losses may occur because the quality of the boiler itself is not good enough, or the furnace operator does not operate properly. Zhengzhou Fangkuai Boiler Factory is here to talk about how to solve some common problems in the operation and use of steam boilers.

During the operation of a steam boiler, three common problems are mainly: the exhaust speed cannot meet the requirements, low-temperature corrosion, and damage to the steam and water supply pipes. The common problems of low-temperature corrosion are chemical and electrochemical corrosion. The above two kinds of corrosion occur on the wall whose temperature is lower than the acid dew point. If the dust on the heating area is not cleaned in time, the corrosion rate will be accelerated.

For steam boilers, in addition to corrosion, the common reasons for slow exhaust speed are as follows:
       The filter element of the exhaust outlet is blocked and the inlet filter is blocked. The solution is to replace the filter element, change to a larger pipeline, or shorten the pipeline distance in design. Clean the filter and install a filter.
       Another point is that the steam pipe and water supply pipe of the steam boiler system are damaged and make noise. Deal with this situation in time, and the solution is as follows: if the water supply pipeline is slightly leaked, it will not affect the normal water supply of the boiler or cause the expansion of the fault. It can maintain the operating state in a short time, adjust and use the standby boiler as soon as possible, and do not continue to use it. To avoid intensified failures and threats to personal and equipment safety, boiler operators should contact boiler system maintenance personnel in a timely manner to perform maintenance work on steam boilers.

In addition to the boiler itself, there are other problems in the boiler system, such as centrifugal pumps, burners, condensers and other system components.

Gas boilers are a common type of furnace that uses natural gas as the main fuel. According to the different output media, they are divided into two categories: gas steam boilers and gas hot water boilers. Compared with other types of boilers, gas boilers have some special features in their combustion methods, which can help you better complete boiler selection. Zhengzhou Fangkuai boiler manufacturer will briefly tell you.

First of all, gas-fired steam boilers and gas-fired hot water boilers also have certain differences in their combustion methods. Most of these boilers use fire chamber combustion, and the combustion chamber carries out layered combustion. This type of furnace is generally small and basically less than 20 tons. , Mainly for commercial or civilian use. It is also relatively automatic in the use of fuel regulation.

Gas-fired hot water boilers generally use boiling combustion, and the other is cyclone combustion. The two combustion methods are completely different. Natural gas has an advantage over other fuels in burnout. When the high-temperature flue gas burns out, the furnace is further cooled. Burn-out cooling greatly improves the relative speed with air, which not only strengthens combustion, but also further improves the thermal efficiency of hot water boilers. With less cooling, it is also conducive to the loss of gas; therefore, the operating cost of gas-fueled boilers And there are still great advantages in terms of emissions.

In recent years, gas boilers have undergone continuous technological breakthroughs and improvements. The current operating efficiency has far exceeded coal-fired boilers, biomass boilers, etc., reaching as high as 98%. Therefore, the cost of operation is very cost-effective; The environmental protection factor is also very high. Compared with coal-fired boilers, the nitrogen emission exceeds the relevant standards. In addition, there are many shortcomings such as dust and special maintenance. At present, more and more people choose to abandon the use of coal-fired boilers. Choose a gas boiler.

Through the policies issued by various provinces and cities in my country in recent years, it can be seen that my country’s current environmental protection requirements are becoming more and more stringent. Some areas in Beijing have reached the regional emission standard of 30 mg/m3, which is important for sustainable development. Is very helpful. In combination with the current environmental protection policies, great changes have also taken place in the boiler industry. More and more companies require the use of low-nitrogen-emission boilers, while traditional boilers have high pollution rates, large area, and inconvenient use. Multiple shortcomings are gradually eliminated. So, compared with traditional boilers, what are the outstanding advantages of gas-fired low-nitrogen boilers? Let Zhengzhou Fangkuai Boiler Factory provide you with comprehensive answers.

1. The difference in emissions between traditional boilers and gas-fired low-nitrogen boilers
       Due to the different combustion methods and furnace structures of stratified, chamber, and circulating fluidized bed boilers, the nitrogen oxide (NOx) emissions of these two types of boilers are also quite different. Generally speaking, when using low nitrogen combustion in the furnace In terms of technology, the original NOx emission of the circulating fluidized bed is low, and the original NOx emission of the layer-burning furnace represented by the chain furnace is slightly lower. The pulverized coal industrial boiler is a room-fired boiler. The higher the original NOx emission, the higher the emission of the domestic low-nitrogen boiler. But greatly reduced.

2. Traditional boilers and gas-fired low-nitrogen boilers use different technologies
       Stratum fired, chamber fired, and circulating fluidized bed boilers can adopt different low-nitrogen combustion technologies according to different combustion methods. For stratified fired boilers, air classification and flue gas recirculation are often used to achieve low-nitrogen combustion; Under the influence of recirculation on the combustion of the typical section of the stratified combustion boiler, combined with the air classification technology, the NOx is catalytically reduced by semi-coke; the furnace reduction denitrification technology is an emerging furnace denitrification technology in recent years, and the combustion flame area is sprayed at a reasonable position Ammonia, to achieve direct denitration in the high temperature flame. Low-nitrogen boilers mainly adjust the position and distribution of secondary air outlets and coal feed outlets, or increase flue gas recirculation systems.

3. The safety of traditional boilers and gas-fired low-nitrogen boilers is different
       After a large number of experiments on the low-nitrogen combustion technology in the furnace of stratified, room-fired, and circulating fluidized bed boilers, they have been verified in engineering applications. Generally speaking, low-nitrogen boilers have higher safety and are also used by many users. The reason for choosing it.

It can be seen that the gas-fired low-nitrogen boiler is a kind of product that is truly energy-saving and environmentally friendly. The low-nitrogen boiler technology adopted by it has been verified by many tests and engineering applications, and has achieved significant results, not only protecting the environment, but also As far as the users are concerned, energy saving is also achieved, which is a double effect.

Zhengzhou Fangkuai Boiler Factory has tracked and investigated the boilers used by customers for many years. It is shown that boilers that undergo regular inspections can extend their service life by at least 5 years and have a very low failure rate compared to boilers that are not inspected and maintained. Regular maintenance and inspection can prevent most of the boiler problems and reduce losses for users.

Zhengzhou Fangkuai Boiler Factory recommends that, whether it is a hot water boiler or a steam boiler, an oil or gas boiler, regular maintenance and overhaul of the boiler is essential, that is, a regular maintenance of the boiler in use or out of service. an examination. Not only the boiler equipment itself, but the inspection of the entire boiler system is also necessary. The use of auxiliary equipment and its auxiliary equipment are inspected. The regular inspection of gas boilers generally includes: internal inspection, external inspection, hydraulic test, valve pump valve inspection, etc. The specific content is as follows.

Internal inspection: refers to the inspection of the gas boiler in shutdown and the inspection of the safety status of the boiler. Internal inspection can find out what needs to be maintained or maintained during boiler design, manufacturing, installation and repair.

External inspection: refers to the inspection of the safety status of the gas boiler under the operating state, that is, the inspection under the operating state of the hot water boiler in the past. External inspection can find problems in boiler management, the operating level of boiler equipment, and whether safety accessories and protection devices meet the requirements, and at the same time can check the operating status of the boiler system.

Water pressure test: refers to the pressure test performed on the pressure parts of the boiler with water as the medium and the specified test pressure. The purpose of the hydraulic test is to inspect the strength and tightness of the pressure parts of the boiler, which complements the internal inspection and external inspection to form an inspection of the gas boiler and boiler system.

It can be seen that the gas-fired boiler physical examination can troubleshoot boiler hazards, reduce boiler accidents, and ensure that boiler equipment can maintain good operating conditions during heating and heating in winter.
