Heat Exchangers in Boilers - Semantic Scholar

2018-8-9 · Flue gases exiting the boiler can be cooled down close to the dew point (t=150-200 °C). Air preheaters and economizers recover heat from the furnace exit gases in order to reduce to preheat combustion air (thus increasing efficiency) and use the heat to increase the temperature of the incoming feed water to the boiler.

Air preheater - Wikipedia

2019-10-27 · Types. There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater. These may be arranged so the gas flows horizontally or vertically across the axis of rotation.
