AIR PREHEATER BASKETS – HEATING ELEMENTS GGH (GAS

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.
