WASTE HEAT RECOVERY - THE AIR PREHEATER

1975-1-21 · WASTE HEAT RECOVERY . The usual approach is simply to dilute the hot gas with cold ambient air until a suitable low temperature is obtained. Such a procedure satisfactorily lowers the temperature of the hot gas to predetermined levels but it also wastes substantial quantities of heat in raising the cool ambient air to a suitably high

Why Economizer and Air Pre-Heaters are Provided in

If economizer alone is provided then the efficiency will be lower by 12 % when compared to that with economizer and air pre-heaters. Both economizer and air pre-heaters are called heat recovery system in a boiler. But for these heat recovery systems the present day boilers would have been operating at much lower efficiency levels.
