Comparative analysis on two combined systems with air heater and lowpressure economizer

Abstract

Abstract:

Taking a 300MW unit as an example, compared the classic layouts and energysaving schemes of two combined systems with air heater and lowpressure economizer. Through theoretical analysis, the differences of coal consumption between 2 schemes is 0.89g/(kW·h) under heat consumption acceptance condition ,which can provide a reference for the power plant which is willing to carry out a similar transformation.

Key words:

air heater, lowpressure economizer, energy conservation, coal consumption
