Author: Dr V T Sathyanathan By pre-heating the combustion air with the hot flue gases leaving out of the boiler, a considerable increase in efficiency is obtained. The type of Air Pre-heater totally dominating the Power Plant segment is the re-generative type, first and foremost because it is extremely efficient which results in reduced space requirements and a lower price.

Air preheater is one of the accessories of steam generators, that works as a heat exchanger that utilizes the heat of the flue gas of the boiler, heating the air needed for the combustion of the fuel, thereby increasing the thermal efficiency of the

Rotary regenerative air preheaters have a much reduced size and cost relative to recuperative tubular or plate heat exchangers. Howden's air preheaters are engineered to meet the demands of your application. We manufacture our air preheaters in modern facilities based around the world and produce bisector, trisector and quadsector arrangements.

Air Preheaters (APH) Air Preheaters (APH) is the Shell and tube type Heat Exchangers used for preheating the air which is fed to the boiler or furnaces/kilns for combustion of fuels. Air Pre heater’s primary objective is to extract the waste heat from the flue gases leaving the boiler.

[PDF]heaters Air heater leakage % can be determined using this procedure, which is defined as the weight of air passing from the airside to the gas side of the air heater.

The purpose of the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat loss in the flue gas. As a consequence, the flue gases are also conveyed to the flue gas stack (or chimney) at a lower temperature,

Since 1990, the independent experts in heat transfer technologies. For a quarter of a century, LAPCO designers and engineers have devised precise, cost-effective systems for such diverse applications as:
