The boiler air preheater is a regenerative heat exchanger for industrial boilers, and heats combustion air via fuel gas, steam, hot water, or oil from the boiler flue. When the exhaust temperature of the combustion system is high, an air preheater is recommended for use. The boiler air preheater works in areas where the fuel gas temperature is
An air preheater is another form of heat exchange device that preheats or heats the air used in boiler combustion through a combination of steam, water, flue gas, or thermal oil. The general idea is that a boiler's combustion process is more efficient if the boiler has to work less to produce the same amount of energy.

A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming.There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet
