Boiler Economizer: What is it? (Function & Construction

Mar 04, 2020 · 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 hence recovering more useful enthalpy and improving the steam boilers efficiency.

Boiler stack economizer - Énergir

Boiler stack economizer CONCEPT A stack economizer is an exchanger designed to recover the heat contained in the hot flue gases from boilers; the heat is transferred to a hot water system. In the case of a steam boiler, about 20% of the energy required for the burner ends up in the flue, often at high temperatures.

Use Feedwater Economizers for Waste Heat Recovery

A feedwater economizer is appropriate when insufficient heat transfer surface exists within the boiler to remove combustion heat. Boilers that exceed 100 boiler horse-power, operating at pressures exceeding 75 psig or above, and that are significantly loaded all year long are excellent candidates for an economizer retrofit.

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

Economizer - an overview | ScienceDirect Topics

Economizers for boilers have been available for nearly 150 years, almost as long as boilers themselves. For modern shell boilers, high efficiencies have made it increasingly difficult to justify the use of an economizer, the final decision being based in terms of payback period, which is also heavily dependent on fuel prices.
