Steam generator is a mechanical equipment that uses the heat energy of fuel or other energy to heat water into hot water or steam. It belongs to small equipment and is also a kind of steam boiler. Its water volume is less than 30 liters, which belongs to the steam boiler exempt from inspection. According to the regulations of Boiler Safety Technical Supervision, the water volume is less than 30 liters, which is not within the scope of boiler supervision.
Steam boiler is through the combustion of fuel to release heat energy, and through the heat transfer process, the heat transfer water, so that the water has a certain temperature and pressure of steam heat exchange equipment, widely used in the production of factories and enterprises. It belongs to special equipment, high requirements for enterprise qualification, product safety, and the need for annual inspection.
The difference between a steam generator and a boiler in a nutshell is that a steam boiler contains a steam generator, but a steam generator is not a steam boiler.
Generally speaking, the rated thermal efficiency of 1 ton boiler is 0.7MW (700KW), 0.7mw heating area is regional differences, heating 50~70W/㎡, 1 ton hot water boiler heating area is generally 6000~10000 ㎡. Now some areas also stipulate heating 32W /㎡, 32W can be nearly 15,000㎡, the specific design should leave a margin.
Conversion formula: 600,000 kcal/h ≈1ton/h≈0.7MW
Advantages of hot water boilers: This type of boiler achieves the advantages of full combustion, no pollution, convenient operation, and convenient installation; this type of boiler has high thermal efficiency, large output, strong load adaptability, high degree of automation, convenient operation, safe and reliable operation, and is high-efficiency, low-consumption, low-pollution green products.
We believe that many customers in the purchase of steam boiler, have heard a lot of boiler manufacturers talk about the need to equip boilers with softeners. For the steam boiler, what is the necessity? Today we will introduce the water softener in detail.
1.Soft water refers to water that has been softened and deoxygenated by the equipment. Soft water treatment can reduce the content of calcium and magnesium salts in tap water, mineral water and other hard water, so that the water quality can meet the requirements of boiler equipment.
2.Boiler using soft water advantages: 1) When the boiler uses the water softener, it greatly saves the waste of a lot of fuel. When the boiler boils water, there will be a thick layer of scale slowly, for the working pressure of 1.4mpa boiler will form 1 mm scale, it will waste 8% of the fuel. Not only the waste of fuel, but also the pollution of the environment.
2)Water softener can improve thermal efficiency and reduce output. When scale occurs on the evaporation surface of the boiler, the output of the boiler will be reduced because the heat from the fire side cannot be transferred quickly to the feed water side. If the water is not treated properly, when the boiler scale occurs, the boiler steam will be greatly reduced.
3)Using a water softener will reduce boiler maintenance. When a large amount of scale is produced in boiler pipes, it is difficult to remove. Scale will cause boiler leakage, deformation, corrosion and a series of hazards. It not only damages the boiler, but also consumes a lot of manpower and material resources to overhaul, not only shortens the operation time, but also increases the overhaul cost.
4)The application of water softener effectively reduces the occurrence of accidents. For such as the selection of softening water equipment, must be in line with the principle of quality, safety, in order to ensure that the water softening processing can play an effective role.
According to the equipment requirements of steam boiler, the use of water softener is one of the necessary conditions to ensure the stable operation of the boiler. Therefore, professional boiler manufacturers will emphasize to customers that water softeners should be equipped.
The tonnage conversion between gas steam boilers and gas hot water boilers. Many users do not know well, and they use the term “ton” uniformly. In fact, for hot water boilers, “MW” should be used to indicate that the tonnage and model should be more appropriate.
The power of the hot water boiler is MW, 1T = 0.7MW = 720kW = 600,000 kcal
The consumption of boilers per hour is the focus of many users’ attention, which is related to the cost of the user unit for the boiler. Generally speaking, the measurement of boiler consumption is mainly depending on the operating efficiency. The higher the operating efficiency of the boiler, the lower the consumption, and the less cost. Henan Xinda’s gas boiler operating efficiency is generally more than 98%. For example, 1 ton of gas boilers consumes about 70 cubic meters per hour. It is a very low gas consumption cost in the entire boiler market.
After a period of operation of the gas boiler, the equipment and auxiliary machinery of the boiler will produce wear, leakage, corrosion or other damage reasons. If it is not maintained or repaired in time, the safe operation of the gas boiler will become a big hidden danger. So today we want to understand how to do daily maintenance and maintenance of gas boilers, to ensure the original performance of the boiler and the service life of the boiler.
Boiler cleaning: there will be some residue in the boiler combustion chamber, which needs to be cleaned inside the boiler and its gas pipeline.
Boiler anti-freezing: in cold winter, the temperature is below 0 degrees in the area need to take anti-freezing measures on the boiler: if the boiler room is outside, then the indoor temperature is reduced to 15-18 degrees, let the boiler run all day; If the room is unoccupied for a long time, the boiler needs to be drained.
Boiler sewage: Because the flue gas and flue gas temperature is too low, there is water, remove this part of the water from the chimney, and part of the chimney wall absorbed, the rest of the water deposited at the bottom of the chimney, the purpose of regular blowdown is to remove the sediment in the furnace, adjust the quality of the furnace water.
During the operation of the steam boilers, the water quality will be checked regularly to ensure the quality of the steam, and at the same time, the sewage will be discharged frequently. Then, why should the steam boilers discharge sewage? Xinda boiler introduces you：
During the operation of the boiler, the boiler water with more salt and water slag is discharged to the outside of the boiler, which is called boiler blowdown.
The feed water entering the steam drum always contains a certain amount of salt. After dosing in the boiler, the fouling substances in the boiler water will be transformed into water slag. In addition, the boiler water will also produce some corrosion products when corroding metals. Therefore, there are various soluble and insoluble impurities in the water.
During the operation of the boiler, only a small part of these impurities are taken away by the steam, and most of them remain in the boiler water. With the continuous evaporation of the boiler water, the concentration of these impurities gradually increases. big. Excessive concentration of impurities in boiler water will not only affect the quality of steam, but also cause scaling and corrosion of the heating surface, affecting the safe operation of the boiler. In order to control the quality of boiler water, boiler blowdown must be carried out to discharge part of the boiler water contaminated by salt and water slag, and supplement it with clean feed water.
We have introduced the reasons and methods of blowdown of steam boilers above. When using boilers, users should always pay attention to the operating conditions of the boilers, and discharge the blowdown correctly to ensure the quality of steam and the normal operation of production.

How to choose suitable steam boiler according to tempe rature? First of all, it is necessary to know that the steam temperature produced by the steam boiler is related to its pressure, and is directly proportional.
According to boiler pressure, it can be divided into:
2. Medium pressure boiler. The outlet steam pressure is 2.94-4.90MPa, generally speaking, the outlet steam pressure of medium pressure boiler is stipulated as 3.83MPa, and the steam temperature is 450℃.
3. High pressure boiler. Outlet steam pressure is 7.84-10.8MPa; Generally speaking, the outlet steam pressure of high pressure boiler is 9.81MPa, and the outlet steam temperature is 540 ℃.
It uses the most mature three-pass all wet back structure in the world. which safe and reliable. The use of waveform furnace can strengthen disturbance of smoke, increasing the heat transfer area of radiation, which can not only enhance the heat transfer effect, and also promote oil combustion in the furnace, the entire heating surface is in symmetrical arrangement with strong structure and reasonable system of water cycle. The water capacity in steam drum is large, with large steam room and quality steam and small fluctuations of water level in running. The unique setting of hearth and scouring way of smoke surface reduce the boiler heat loss to be minimal.
