Thermodynamic analysis of a low-pressure

An LPE (low-pressure economizer) based waste heat recovery system for a CFPP (coal-fired power plant) is investigated thermodynamically. With the installation of LPE in the flue before the FGD (flue gas desulfurizer), the heat contained in the exhaust flue gas can be recovered effectively and the water consumption can be reduced in the FGD resulted from the temperature dropped flue gas.

what is economiser in boiler

Boiler Economiser. Economizer is a heat exchanger device that recycles energy produced within a system or leverage environmental temperature differences to achieve efficiency improvements. Boiler Economizer captures waste heat from boiler exhaust and transfers this waste heat to boiler's feed water or return water circuit,
