Gas plate heat exchanger (gas heat exchanger) and residual heat recycling1. The air heat exchanger is mainly plate heat exchanger. Compared with the tube heat exchanger, the heat transfer coefficient of the plate -type heat transfer device increases by 50%-200%, and the steel saves 50%-70%, accounti

What is an air preheater?

Where are air preheaters generally used?Adapt to the environment: coal-fired boilers, gas-fired boilersAdapt to flue gas temperature: boiler room with flue gas temperature higher than 120℃Application principle of air preheaterDuring the operation of the boiler, it is necessary to discharge flue gas

Air preheater is a gas-gas type heat exchange equipment, which uses flue gas to heat the air. This product is widely used in the latent heat recovery system of blowing air in the gas making section of chemical fertilizer plants, waste heat recovery of boilers, petroleum, metallurgy, etc. When the te

A large amount of air needs to be consumed in the combustion process of the boiler. Before combustion, the air at room temperature needs to be heated to about 300 ℃, and then the air participates in the combustion. The heating process of the air also consumes a part of the fuel combustion energy.Aft
