Rotating Regenerative Heat Exchanger Brochure

Air Preheoters (APH) are important components in modern fossil fuel fired power stations. By preheating the combustion air with the hot flue gases leaving the boiler, a considerable increase in efficiency is obtained. In recent years, the attention has also been focused on a reduced need of maintenance, longer operational periods between major overhauls, and the need of operating in connection with flue gas cleaning equipment such as high dust SCR (Selective Catalytic Reduction) plants. The type of air preheater totally dominating the market is the regenerative type, first and foremost because it is extremely efficient which results in reduced space requirements and a favourable price.
