Condensing technology has been widely recognized by the boiler industry in recent years. Take the oil and gas boilers launched by Zhengzhou Fangkuai Boiler Factory. After the addition of condensing technology, the operating efficiency of the boiler has risen sharply, reaching as high as 107%. How does condensing technology work? Come and see it with Zhengzhou Fangkuai Boiler Factory.

For oil-fired gas boilers, the heat emitted by a unit mass of fuel when it is completely burned is called the calorific value of the fuel. Fuel calorific value is divided into high calorific value and low calorific value. The high calorific value refers to the total heat released when 1Kg fuel is completely burned, including the latent heat of vaporization released by the water vapor in the flue gas that has condensed into water. When the latent heat of vaporization of water vapor in the flue gas is deducted from the high calorific value of the fuel, it is called the low calorific value of the fuel.

Obviously, the high calorific value is larger than the low calorific value in value, and the difference is the latent heat of vaporization of water vapor. Taking natural gas as an example, its high calorific value is about 9500 kcal/m3, and its low calorific value is about 8600 kcal/m3. The difference is about 900 kcal/m3, accounting for about 11% of the low calorific value.

Boiler equipment using condensing technology can re-use the high-temperature flue gas discharged from the boiler and recycle it into the operation of the boiler, thereby achieving the purpose of energy saving and emission reduction.

The history of hot water boilers can be traced back to a long, long time ago, and steam boilers have been popularized in the past 200 years, which has a certain impact on traditional hot water boilers. If the space available for the former is small, or subject to greater restrictions, people will quickly choose the latter soon. The area required by the steam boiler is also relatively small, only 60% of that of the hot water boiler, and it does not require special renovation plans and indoor layout adjustments. The steam boiler not only has the advantage of occupying a small space, but also consumes less water in the furnace. The boiler can produce steam within 5 to 7 minutes after starting in the cold state, while the hot water boiler is about 60 minutes after starting in the cold state. Steam can only be started after ~90min.

When the boiler is out of service for a long time, shutting down must also be considered. The steam boiler embodies energy-saving advantages when it is started, and can save 5% to 11% of energy on average; while the former still has energy loss under normal and continuous operation: heat radiation and source loss through the chimney. Moreover, after the hot water boiler is out of service for a long period of time, it will take a long time to return to normal working condition.

The hot water boiler can provide a large amount of high-pressure hot water, wet steam and superheated steam, but the pressure it can achieve is only 32 bar. Under today's technical conditions, the achievable hot water temperature can reach 240°C and the steam flow rate can reach 45t/h. From the current popular point of view, the use of a fast steam boiler to provide wet steam is the most ideal solution: compared with the wet steam provided by the former (relative humidity 2% to 3%), the relative humidity of the wet steam provided by the fast steam boiler is only 0.5%, which can reduce the hazards caused by steam condensation in the steam pipeline, and has very good heat transfer performance during use.

Enough steam due to the small amount of internal water and the thinner wall thickness of the furnace body can reach the predetermined steam pressure in a short time, and the pressure value can be kept stable when the load changes. It does not need to be monitored under certain working conditions. Because the steam boiler consumes less water during operation, it is classified as Class III or Class IV in the equipment operation safety level regulations. When using a hot water boiler, when the pressure and capacity of the boiler exceed certain specifications, you must apply for a license before putting it into production.

In boiler equipment, the formation of scale is the precipitation of solid substances from the supersaturated boiler water. A certain salt dissolved in the boiler water has a certain solubility. If the solubility limit is exceeded, the boiler water becomes a supersaturated solution of a certain salt. At this time, the excess part is dissolved out of the furnace water. So what are the effects of scale on the boiler? Are these effects positive or negative? The technical engineer of Zhengzhou Fangkuai Boiler Factory has something to say.

First of all, we must first understand what are the components of the scale in the boiler: 1. The fouling substances are mainly derived from the impurities contained in the feed water; 2. The impurities include the dissolved, colloidal or suspended matter in the feed water; 3. Common There are calcium carbonate, calcium sulfate, calcium silicate, magnesium hydroxide, etc.; 4. Under special circumstances, iron scale, oil scale or other organic scales may also be generated.

Secondly, it is necessary to have a certain understanding of the distribution law of scale in the boiler: 1. Generally there is secondary scale in the header; 2. The scale accumulated at the bottom of the drum is generally the scale that falls off the smoke pipe; 3. The formation near the water supply pipe The scale is generally dominated by carbonate salt; 4. The mixed scale of silicate or sulfate is usually generated in the water wall pipe; 5. When the water source is changed or the water treatment method is changed, a large amount of scale may fall off; 6. Boiler The scale is generally distributed on each heated surface; the scale formed on the non-heated surface is generally secondary scale.

For boiler equipment, the harm caused by scale is huge. Excessive scale will destroy the normal water circulation of the boiler, causing defects such as overheating, deformation, material deterioration, and cracks on the heating surface of the boiler. In severe cases, it will also reduce the thermal efficiency of the boiler, increase the production and equipment maintenance costs of the enterprise, and cause safety problems, causing personal injury and death.

How much gas can a 1 ton steam boiler produce per hour? Generally speaking, a 1 ton steam boiler means that it can produce 1 ton of steam per hour, and a 1 ton steam boiler can produce 1 ton of steam per hour when operating at full load. However, in the actual application process, leakage and sewage discharge may occur, and the loss rate caused is in the range of 1 to 5%. Although the leakage can be reduced by improving the sealing degree, the sewage discharge is unavoidable. From this point of view, the amount of steam produced by a 1-ton boiler per hour is closely related to the quality of the boiler and the actual operation of the user.

Zhengzhou Fangkuai Boiler Factory has launched a wide range of steam boiler fuel coverage, which can use gas fuel, oil fuel and electricity. There are dozens of boiler models for users and friends to fully choose. The gas-fired steam boilers, oil-fired steam boilers, and electric steam boilers introduced have outstanding performance in terms of quality and operating efficiency.

What is the gas consumption per hour of a 1 ton gas-fired steam boiler operating?

The calculation formula for gas consumption of gas boiler is: gas consumption of gas boiler (per hour) = gas boiler power * time / fuel heating value / gas boiler heating value utilization rate. The power of a 1 ton gas boiler is 0.7MW, the calorific value of the fuel is calculated at 35.53MJ/N per cubic meter, and the thermal efficiency of the boiler is calculated at 98%. Then, the consumption of 1 ton natural gas boiler in 1 hour = 0.7MW*3600 seconds/35.53MJ/Nm3/98%. According to the theoretical data formula, the gas consumption of 1 ton natural gas boiler is about 72.37 cubic meters. At the same time, it can be found from the above formula that the gas consumption of the boiler is also affected by the heating value of the fuel and the thermal efficiency of the boiler.

It can be seen that whether it is "How much gas can a 1-ton steam boiler produce per hour?", "What is the gas consumption per hour of a 1-ton gas-fired steam boiler operating?", etc., they are all related to the operating efficiency and overall quality of the boiler. . When purchasing steam boilers, you must compare them in multiple dimensions. If you only look at the price, you will inevitably be a bit one-sided.

Agriculture occupies an important position in our country, providing people with all aspects of food, clothing, housing and transportation. Fertilizers are very important to agriculture and are related to the quality of agricultural product harvests. What kind of steam boiler is better to use in the process of fertilizer processing in a fertilizer plant? Zhengzhou Fangkuai Boiler Factory has something to say.

The heat energy that needs to be used in the process of fertilizer processing in the fertilizer plant must meet the following requirements:
       1. A large number of different specifications and types of steam are required to provide heat and be used as raw materials for production; 2. Need a lot of driving power to compress gas and pump fluid;

The history of winemaking in our country is very long, dating back thousands of years. The ancient winemaking process is more cumbersome to operate. With the development of modern technology, the winemaking process has become more sophisticated. In the brewing process, there are two processes inseparable from steam, one is fermentation and the other is distillation. The steam boiler is an important production equipment for the winery.

I believe everyone knows that the temperature and purity of steam produced by different types of steam boilers are different, and the operating costs are also different. In the past, because the production technology was not very advanced, wine-making enterprises used coal-fired steam boilers for production. However, with the development of technology, there are many types of steam boilers that can be used now. You can pursue higher cost performance according to actual needs. Steam boiler.

1. Fuel gas steam boiler
       Oil-fired gas-fired steam boiler is a type of boiler that uses oil, gas, etc. as fuel. With the implementation of the West-East Gas Pipeline, the price of natural gas has dropped to a certain extent, and the operating efficiency of oil-fired gas-fired boilers is very high. The operating efficiency of such boilers launched by Zhengzhou Fangkuai Boiler Factory can reach as high as 107%. At present, there are more companies using oil-fired and gas-fired steam boilers for winemaking.

2. Biomass steam boiler
       Biomass steam boiler uses biomass pellets made from agricultural and forestry waste as fuel. Biomass particles have a wide range of sources and are relatively easy to obtain. Since the wine tank produced in the winemaking process can also be used as fuel, biomass steam boilers are also one of the choices for many wineries to purchase boilers.

3. Electric heating steam boiler
       Electric heating steam boiler is a kind of boiler equipment that converts electric energy into heat energy. There is no combustion phenomenon during the capacity conversion process. Therefore, the operation process is pollution-free and noise-free, and has been loved by many wineries.

The above-mentioned types of boilers are the types of steam boilers that brewing companies choose to use. Of course, as to which one to choose, you should make a reasonable choice based on your actual needs and your own situation. It will be more efficient to directly consult a professional boiler manufacturer.

Water is one of the indispensable substances in the operation of oil and gas boilers. If the boiler wants to produce a large amount of steam or hot water, it needs a large amount of water to enter the boiler. It can be said that the water quality is very important for the boiler. . If the boiler inlet water is of poor quality and flows directly into the boiler without any treatment, it will bring extremely serious harm and adverse effects to the oil and gas boiler.

1. Poor water quality will cause scale in oil and gas boilers
       When suspended solids, colloids, and inorganic salts are heated or exceed their saturation concentration, they will settle and precipitate, forming sludge and scale, which greatly affects the boiler's heat transfer efficiency and boiler water circulation, fuel waste, heating surface damage, boiler output decline, and cleaning Increase in volume. There is a scale of 1 mm thick, which wastes 10% of fuel. When a boiler of 10 kgf/cm2 runs without scale, the tube wall temperature is 280. C. After 1 mm thick silicate scale is formed, the temperature of the tube wall rises to 680 due to the increase in thermal resistance. C. At this time, the strength of the steel plate is reduced from 40 kgf/cm2 to 10 kgf/cm2, which causes the pressure of the boiler to drop, and the furnace wall cracks, bulges, or even bursts. When the scale is serious, serious accidents such as blockage of furnace tubes, waterways, boiler shutdown and boiler explosion, etc. occur. The boiler shutdown causes freezing and cracking of production equipment and heating equipment also occur from time to time.

2. Poor water quality will cause corrosion of oil and gas boilers
       Poor water quality causes metal corrosion, which leads to the destruction of boiler metal components. The metal corrosion products form new structural materials and produce under-scaling corrosion, which accelerates the damage of metal components.

3. Poor water quality will cause oil and gas boilers to produce steam and water.
       The phenomenon that the water droplets in the furnace drum of the steam boiler are taken away by the steam is called co-leakage of steam and water. One of the reasons for this is that the water contains more impurities such as sodium chloride, sodium phosphate, silicide, and organic matter. The production of steam and water will cause serious pollution of the steam, the superheater tube and the steam circulation tube will accumulate salt, and the pipeline will be blocked in severe cases, the steam temperature will drop, water will be produced and corrosion will be broken.

4. Poor water quality will cause caustic embrittlement of oil and gas boilers
       Caustic embrittlement refers to the irregular damage-explosion caused by low-carbon steel, alloy steel and stainless steel when the tensile stress exceeds the yield point and at the same time is in contact with the concentrated caustic soda solution.

Through the Zhengzhou Fangkuai Boiler Factory, I will explain to you the harmful effects of poor water quality on oil and gas boilers. For units that do not pay much attention to water treatment, the operating conditions of their boilers are often: one year is good, two years old, and three years burn out. This will not only bring huge economic losses, but also cause major safety accidents such as production shutdowns and explosions.

Recently, the front-line consultants of Zhengzhou Fangkuai Boiler Factory have received calls from many users. Some of them purchased boiler equipment from other boiler factories. After 1-2 years of use, they found that there was a lot of dirt inside the boiler and did not know how to deal with it. Today, the technical engineer of Zhengzhou Fangkuai Boiler Factory will come to answer for everyone, why the oil and gas boilers need to carry out regular blowdown operations.

Everyone must clarify what are the purposes of sewage discharge for oil and gas boilers.
       (1) Exclude excess salt and alkali in boiler water, so that all indicators of boiler water quality are always controlled within the scope required by national standards.
       (2) Eliminate the sludge formed in the boiler.
       (3) Grease and foam on the water surface of the sewage boiler.

The regular blowdown of oil and gas boilers also has many positive meanings.
       (1) An important part of the water treatment work during the boiler blowdown is an important means to ensure that the boiler water quality concentration meets the standard requirements.
       (2) Implementing planned and scientific blowdown to ensure good boiler water quality is an important measure to slow down or prevent scale formation, ensure steam quality and prevent boiler metal corrosion.

Gas-fired boilers have become one of the first-choice equipment for many enterprises and units during production and processing, and are widely recognized for their high efficiency, energy saving, and environmental protection characteristics. As the gas boiler is a special equipment, it is particularly important to ensure that it can always operate safely. How can we ensure the safe and stable operation of the gas boiler? The professional technical engineers who have worked in Zhengzhou Fangkuai Boiler Factory for many years will answer you.

1. Make sure to use the correct specifications for operating gas boilers
       Boiler accidents caused by improper operation are a very common one, so this requires that professional furnace personnel must strictly operate the boiler in accordance with the boiler operation regulations when the boiler is in operation.

2. Strictly manage the gas boiler room
       The boiler room is the place where the boiler is placed. The safety of the boiler room is directly related to the safe operation of the boiler. Open flames are strictly prohibited in the boiler room, and fire-fighting equipment must be provided.

3. Correct handling in case of emergency in a gas boiler
       Nothing is 100% safe. If there is an emergency during operation, you must make a prediction plan in advance, such as water cuts, power cuts, burns, insufficient pressure or equipment failures, etc., and you must have the ability and be able to solve them in time .

4. Cultivation of employee safety awareness
       Users regularly provide employees with boiler safety training to promote employees' safety awareness.

5. Scientific maintenance after shutdown
       The safe operation and maintenance of gas boilers is very important. Boiler maintenance can not only extend the service life of the boiler, but also play an important role in the safe operation of the boiler.

The above are the five aspects that Zhengzhou Fangkuai Boiler Factory summarized for you to ensure the safe operation of gas boilers. If you strictly follow the above aspects, I believe that the boiler will be used for ten or even twenty years without problems.
