2020/11/27 · The economizer is the heating surface in the tail flue of the boiler that heats the boiler feed water into saturated water under the pressure of the steam drum. Because it absorbs relatively low temperature flue gas, it reduces the flue gas exhaust temperature and saves It improves energy and efficiency, so it is called an economizer.

Firstly, by reducing gas consumption and secondly, there is a substantial saving on the much-discussed CO2 emissions tax. The project consists of liquid/gas heat exchangers (economizers and flue gas condensers) recovering the waste heat from the exhaust gas of the boiler plant (incl. 6MW gas turbine) and leaving the flue gas at a temperature of ~40°C.
