Product Description

Product Description

 

Economizer  is a device installed at the lower part of the flue at the tail of the boiler to recover the waste heat of the exhaust gas. It heats the boiler feed water into a heating surface of saturated water under the pressure of the drum. Because it absorbs the heat of high-temperature flue gas, reduces the exhaust gas temperature, saves energy and improves efficiency, it is called an economizer.

There are three stages from the feed water in the boiler heated into superheated steam:feed water preheating, evaporation, and superheating. The three stages are finished on three different heating surfaces. The boiler steam and water circuit are composed of the three different heating surfaces as well as their connecting pipes. Boiler economizers are one of them, and it is right the equipment to preheat the feed water. Thus, it is the heating surface with the lowest temperature for boiler working fluid in the boiler steam and water circuit. The working fluid passing through this equipment is monophasic water(non-boiling economizer).
