In general, a preheater is a heat exchanger that increases the temperature of a gas or liquid before it is fed into another process. An air preheater does this specifically for air, taking energy from a process stream to heat incoming air elsewhere in the system. By increasing the inlet temperature at which the air enters … See more There are a variety of applications for air preheaters. Take a power plant boiler, for example. An air preheater can be utilised to recover heat from the flue gas and increase the heat of … See more Depending on where excess heat is available from, either a liquid to air or gas to air preheater will be used. For example, heat may be available … See more WebA preheater (a heat exchanger before a reactor) is being used to preheat separate methane and oxygen streams before they are combusted in a catalytic reactor.
