Economizer - Babcock & Wilcox

Economizers (as well as air heaters) perform a key function in providing high overall boiler thermal efficiency by recovering low level (i.e., low temperature) energy from the flue gas.For each 40F (22C) that the flue gas is cooled by an economizer or air heater in a conventional boiler with air as the oxidant and normal excess air, the overall boiler efficiency typically increases by

Boiler Economizer - Michaels Energy

Exhaust stack temperatures for conventional steam or hot water boilers are typically in the 350 to 500F range, and sometimes even higher than that. Any exhaust gas leaving the stack above boiler room temperature is a loss on the system - the higher the temperature, the greater the loss.

Boiler Economizer: What is it? (Function & Construction

What Does an Economizer Do in a Boiler. A boiler economizer (also known as an economizer) are mechanical devices intended to reduce energy consumption or perform a useful function such as preheating a fluid.A boiler economizer is essentially a heat exchanger that makes a system more energy efficient by taking enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler
