Gas steam generator It is a mechanical equipment that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. But you may think that its thermal efficiency is a little low, so how can we improve its thermal efficiency ?

Increase fuel gas Steam generator Method of thermal efficiency: set air preheater. Air preheater is used for heat recovery, but the problem with air preheater is that low temperature corrosion of materials is easy to occur when sulfur containing fuel is used. In order to control this corrosion to a certain extent, a limit should be set for the metal temperature in the low temperature zone according to the amount of sulfur in the fuel. Therefore, there should also be a restriction on the temperature of flue gas at the outlet of air preheater. In this way, the achievable thermal efficiency can be determined.

Feedwater softening treatment and condensate recovery : Boiler feedwater softening treatment and condensate recovery are also measures to improve the thermal efficiency of equipment. The raw water contains various impurities and scaling substances. If the water quality is not well treated, the boiler will scale. The thermal conductivity of scale is very low, so once the heating surface scales, the output of the natural gas steam generator will decrease, the coal consumption will increase, and the thermal efficiency of the equipment will decrease due to the increase of thermal resistance.

The waste heat boiler is used to heat water or generate steam by using the heat in the waste heat of flue gas discharged from the heat conduction oil furnace. The installation of the waste heat boiler will not change the fuel consumption of the hot oil boiler itself. The hot water or steam generated by the waste heat boiler can be used for production and heating, which can indirectly save fuel.

How to increase Gas steam generator Various analysis and research should be carried out during design. Increasing the heat transfer area of the convection section can improve the thermal efficiency of the furnace. However, generally speaking, the heat transfer area of the radiation section has an appropriate range due to the size of the grate or the shape of the burner, and it is not the best policy to increase the heat transfer area of the radiation section too much. Therefore, the method of increasing the heat transfer area of the convection section is usually used to increase its efficiency.
