Oil-fired and gas-fired boilers refer to boiler equipment that can use oil fuels or gas fuels. Today, my country's environmental protection requirements are becoming more stringent, and it is deeply loved by users, and the frequency of use is also increasing year by year. So, what is the cost of this type of boiler? Zhengzhou Fangkuai Boiler Factory takes a 15-ton fuel and gas boiler as an example to explain to everyone.

The operating cost of a 15-ton oil-fired gas boiler includes water and electricity, fuel, sewage, and maintenance costs. Fuel costs are key expenditures and account for more than 80% of the operating costs. The operating efficiency of the oil and gas boilers launched by Zhengzhou Fangkuai Boiler Factory is generally above 98%. This data is among the best in the entire boiler market. It can be said to be very energy-saving, so the cost is also very low. Around 450 dollars.

Zhengzhou Fangkuai Boiler Factory would like to remind everyone here that during the operation of the boiler, the stability of the primary and secondary steam temperature must be controlled.

Controlling the stable primary and secondary steam temperature during boiler operation is extremely important for the safe and economic operation of the unit. When the steam temperature is too high, the strength of some metals such as superheaters, reheaters, steam pipes, steam turbine cylinders, and rotors will be reduced, which will shorten the service life of the equipment. When the temperature is severely overheated, the heating surface tube will burst. If the steam temperature is too low, the efficiency of the thermal cycle will be affected, and the steam humidity at the non-stage blades of the steam turbine will be too high. In severe cases, water hammer may occur, causing blade breakage and damage. If the steam temperature rises and drops by a large margin, in addition to generating greater thermal stress on the welding joints and connecting parts of the heating surface of the boiler, it will also cause the relative displacement between the cylinder and the rotor of the steam turbine to increase, that is, the expansion difference will increase. Even dynamic and static friction between the impeller and the baffle occurs, causing severe vibration. In addition, the excessive deviation of the steam temperature on both sides of the steam turbine will cause uneven heating and uneven thermal expansion on both sides of the steam turbine. Therefore, the steam temperature should be closely monitored, analyzed, and adjusted during the operation of the boiler, and the most reasonable method should be used to control the stability of the steam temperature.

Oil and gas dual-purpose boiler equipment refers to boiler equipment that can use both gas fuel and oil fuel. The boiler has a very wide adaptability to fuel.

The current boiler price is about 20,000 US dollars.

Here, Zhengzhou Fangkuai Boiler Factory also reminds everyone of the importance of boiler safety valves. In boiler equipment, safety valves are safety devices installed to prevent explosions caused by high pressure in equipment and containers under abnormal conditions.

When the pressure in the equipment is too high, the safety valve automatically opens, and then automatically closes when the pressure drops to a safe range to prevent the equipment from exploding due to excessive pressure. Generally, the constant pressure of the safety valve is 0.5 to 1.1 times of the operating pressure.

According to its structure and principle of action, the safety valve is divided into gravity type, lever type, spring type and so on. The lever type is more suitable when the working temperature is high and the pressure is not too high; the spring type should be used for high-pressure equipment; generally, the spring type safety valve is commonly used.

Various aspects, such as chemical production, food processing, and medical disinfection, require high-temperature steam from a steam boiler. Therefore, 4-ton gas-fired steam boilers are widely used in industrial fields. At present, there are many boiler manufacturers producing 4 tons of gas-fired steam boilers in the market, and the quality of equipment is mixed. Users and friends will inevitably feel confused when purchasing boilers. Zhengzhou Fangkuai Boiler Factory will tell you the price and selection of boilers within the normal range. Type skills.

There are many factors that determine the price of steam boilers, mainly operating efficiency, pollutant emissions, floor space, internal structure, service life, and so on. The higher the configuration of the boiler, the more expensive it will be, but the greater the benefits it will bring, it can be said that it has a very high cost performance. At present, the price of a 4-ton gas-fired steam boiler in the market is between US$30,000 and US$40,000.

Zhengzhou Fangkuai Boiler Factory would like to remind everyone here that the boiler must be equipped with appropriate safety valve facilities to ensure safety during operation.

The pulse safety valve is composed of the main safety valve, the pulse valve and the connecting pipeline.

The main safety valve is controlled by a small pulse valve. Under normal conditions, the main valve is tightly closed by high-pressure steam. When the vapor pressure exceeds the specified value. The small pulse valve is opened first, and the steam is introduced to the main valve piston through the steam guide tube. The pressure of the steam on the piston can overcome the force of the spring compression, so the main valve is opened to discharge the steam and the pressure; when the pressure drops to a certain value, The small pulse valve is closed. The steam flow on the piston is cut off, so the main relief valve is closed again. The residual steam on the piston can play a buffering role, so that the main valve is slowly closed to avoid damage to the valve clack and valve seat due to impact.

Steam boilers are medium-sized equipment among special equipment and are often used in industrial production. Gas-fired steam boilers have many advantages such as high operating efficiency, low pollutant emissions, and long service life. Therefore, they are also very popular in the user market, and their use frequency is increasing year by year. Many users are more interested in the price of a single gas-fired steam boiler. Zhengzhou Fangkuai Boiler Factory takes 6 tons of gas-fired steam boiler equipment as an example to explain to everyone.

At present, the operating efficiency of a single 6-ton gas-fired steam boiler on the market is generally around 70%, which is a relatively medium figure. The gas-fired steam boiler launched by Zhengzhou Fangkuai Boiler Factory adopts a new type of condensing recovery technology, and its operating efficiency can reach more than 98%; combined with low-nitrogen combustion technologies such as full premixing and FGR, the nitrogen oxide emissions of the boiler can be reduced to Below 30 mg/cubic meter, once it was introduced into the market, it was praised by numerous users. At present, the price of a single unit of this type of boiler ranges from US$40,000 to US$40,000, depending on the boiler model and the configuration of auxiliary equipment.

Zhengzhou Fangkuai Boiler Factory is here to remind everyone that in the boiler equipment, the expansion indicator is a relatively important equipment, mainly used to monitor the expansion of thick-walled pressure vessels such as steam drums and headers during the ignition and pressure rise process. Yes, it can be used to detect the deformation of the evaporation equipment caused by improper ignition boost or poor installation and maintenance, and prevent cracks and leaks from uneven expansion. Generally installed on the header and steam drum.

The 8-ton gas-fired steam boiler refers to boiler equipment that can output 8 tons of high-temperature steam per hour, and is commonly used in industrial fields. Many users are not familiar with the selection of gas-fired steam boilers. Facing the numerous boiler manufacturers and boiler types on the market, it is easy to feel confused. Zhengzhou Fangkuai Boiler Factory has recently received inquiries from many users. I am very interested in the price of the boiler. Today, I will give you a unified answer.

There are many factors that determine the price of an 8-ton gas-fired steam boiler, such as boiler model, internal structure, operating efficiency, pollutant emissions, service life, and so on. The 8-ton gas-fired steam boiler launched by Zhengzhou Fangkuai Boiler Factory has two models, WNS and SZS. The operating efficiency is above 98%, and the pollutant emission is as low as 18 mg/m3, which is one of the best in the entire boiler market. Therefore, it has also been loved by the majority of users and friends. The current price of this type of boiler ranges from 60,000 to 70,000 US dollars.

The technical engineer of Zhengzhou Fangkuai Boiler Factory also suggested that everyone should pay more attention to the superheater and reheater inside the boiler. These two accessories are important.

Their function is mainly to discharge the accumulated air, part of the superheated steam and reheated steam when the boiler is started, and to ensure a certain flow rate of the superheater and reheater to cool the pipe wall. In addition, when the boiler pressure rises or in an accident state, the steam and pressure are discharged together with the safety door to prevent the boiler from overpressure. During the start-up process, it can also increase the exhaust steam volume and slow down the boost speed. When necessary, the exhaust steam can also adjust the temperature difference between the two sides of the steam. It can act as an air door when the boiler enters and discharges water. For the reheater to exhaust steam, when the secondary bypass cannot be put into use, the primary bypass can still be used to vent steam to the reheater and exhaust to the empty exhaust valve to protect the reheater effect.

In the field of gas-fired steam boilers, WNS model is a relatively common type of gas-fired steam boiler. The full name of WNS is horizontal, internal combustion, and room-fired boiler equipment. The obvious characteristics of this type of boiler are the reasonable utilization of furnace space, proper structure and layout. Small footprint, high operating efficiency, stable operating state, etc.

Many users are very interested in gas-fired steam boilers, but do not know the selection of boilers and market prices. Zhengzhou Fangkuai Boiler Factory will come to answer your questions. Take a 10-ton gas-fired steam boiler as an example.

At present, the market price of 10-ton gas-fired steam boilers in the market generally ranges between 80,000 and 120,000 US dollars. As for the high intermediate price, it is mainly because of the difference in boiler operating efficiency and quality. The boiler equipment with high operating efficiency is in use. It must be very energy-saving and money-saving, so when you buy a boiler, you should not only look at the purchase cost, but also take into account the later operating costs, so that the boiler can better serve us.

Zhengzhou Fangkuai Boiler Factory also reminds everyone of the importance of safety valves in gas-fired steam boiler equipment.

Safety valve is a safety device installed to prevent explosion caused by excessive pressure in equipment and container under abnormal conditions.

When the pressure in the equipment is too high, the safety valve automatically opens, and then automatically closes when the pressure drops to a safe range to prevent the equipment from exploding due to excessive pressure. Generally, the constant pressure of the safety valve is 0.5 to 1.10 times of the operating pressure.

According to its structure and principle of action, the safety valve is divided into gravity type, lever type, spring type and so on. The lever type is more suitable when the working temperature is high and the pressure is not too high; the spring type should be used for high-pressure equipment; generally, the spring type safety valve is commonly used.

Gas-fired steam boiler is one of the common equipment in industrial production and processing industries. The boiler uses natural gas as fuel. It is very convenient for transportation, installation and later use. It only needs to build water, electricity, and gas pipelines and it can be started and used normally. The boiler adopts low-nitrogen combustion technologies such as FGR and full premixing, and the pollutant emission can be as low as 30 mg/m3.

Many users are more concerned about the price of gas-fired steam boilers. Zhengzhou Fangkuai Boiler Factory takes a 1-ton gas-fired steam boiler as an example to provide answers for everyone. The current market price of a 1-ton gas-fired steam boiler ranges from US$10,000 to US$10,000, depending on the configuration of the boiler, but in general it is within this range.

Zhengzhou Fangkuai Boiler Factory also reminds everyone to pay attention to the use of blowdown expansion vessels on the boiler.

In the boiler equipment, the function of the blowdown expansion vessel is: when the boiler sewage is discharged into the expansion vessel, the volume expands, the pressure decreases, and the saturation temperature also decreases accordingly. Part of the waste water under the original pressure is released after the pressure is reduced. This part of the heat is absorbed by the water as the heat of vaporization and part of the sewage is vaporized. The vaporized part of the steam is introduced into the deaerator for recovery. This part of steam and heat.

The blowdown expander is also called blowdown expansion vessel, and its design and manufacture should be carried out according to GB150-98 of pressure vessel. The continuous blowdown expander is connected to the continuous blowdown port of the boiler. It is used to decompress and expand the continuous blowdown of the boiler. The blowdown is adiabatically expanded in the continuous blowdown expander and separated into secondary steam and waste hot water. After the internal expansion, pressure reduction, heat exchange, and then discharge, the secondary steam is led out by a special pipeline, and the waste hot water is automatically discharged through the float level valve or overflow regulating valve, and the heat energy can be recycled and reused. The continuous blowdown volume is automatically adjusted with the change of the boiler feed water load to maintain a relatively stable blowdown rate.
