Boiler Economizer Coils Made Of SA210C With Handcuffs in ASME Standard
Product Introduction
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.
