Analysis of parameters of Industrial Gas heating Boiler
Capacity
1. When the evaporative steam gas heating boiler runs continuously for a long time, the amount of steam produced per hour is called the evaporation capacity of the gas heating boiler, denoted by the symbol "D", which is commonly used per unit ton per hour.
The evaporation value indicated on the nameplate and design data of gas heating boiler products is rated evaporation, which means that there is no ash accumulation on the heating surface of gas heating boiler, and the original design fuel is used. The amount of evaporation that gas heating boilers can produce per hour under rated feed water temperature and designed working pressure and ensuring efficiency for a long time. In practical operation, it is impossible that the heating surface of gas heating boiler does not accumulate ash at all and the type of coal does not change at all. Therefore, the maximum amount of steam produced by gas heating boiler per hour in actual operation is called the maximum evaporation. At this time, the thermal efficiency of gas heating boiler will be reduced.
2. The heat supply hot water gas heating boiler runs continuously for a long time. Under the rated return water temperature, pressure and prescribed circulating water quantity, the outlet water effectively carries heat per hour, which is called the rated heat supply of the gas heating boiler. The heat of 0.7MW produced by hot water gas heating boiler is about the same as that of 1t/h steam produced by steam gas heating boiler.
Pressure
Why is the pressure in the gas heating boiler? The pressure of steam gas heating boiler is different from that of hot water gas heating boiler. Steam gas heating boiler is because the water in gas heating boiler changes from liquid to gas state after absorbing heat, and its volume increases. Because the gas heating boiler is a sealed container, which limits the free expansion of steam and water, the compressed parts of the gas heating boiler are subjected to the force of steam and water expansion, and the pressure is generated.
the invention relates to a hot water gas heating boiler with a natural circulation heating system, wherein the pressure is from a static pressure formed by a high-level water tank, and the other is a hot water gas heating boiler of a forced circulation heating system, The pressure is derived from the pressure generated by the circulating water pump.
