Flue Gas Heat Recovery Project at Zouping
With carbon emissions allowances for coal-fired power plants becoming increasingly stringent, reducing coal consumption while maintaining stable operational performance has become a crucial priority.
In response, Zouping Power Plant launched a project to enhance boiler efficiency by installing a new low-pressure economizer between the air preheater and the electric stationary precipitator (ESP). In this system, high-temperature (145℃) flue gas flows through the economizer, reducing the temperature to 115℃, to heat up the water from 85℃ to 104℃ then before returning to the deaerator of the feedwater system of the boiler.
