(PDF) IJERT-Thermal Design of Economizer for Waste Heat ...

1 INTRODUCTION:-Economizers are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it. One of the most cost-effective ways of improving the efficiency of a high pressure steam boiler is to install an economizer on the boiler.

Economizer - an overview | ScienceDirect Topics

Economizers are installed in the exhaust gas flow from the boiler. They take heat from the flue gases which they transfer via extended surface elements to the feedwater immediately prior to the water entering the boiler. They therefore increase the efficiency of the boiler and have the added advantage of reducing thermal shock.

Economizers | CleanBoiler.org

Economizers Introduction. Flue gases from large boilers are typically 450 650°F. Stack Economizers recover some of this heat for pre-heating water. The water is most often used for boiler make-up water or some other need that coincides with operation.

Economizer - Babcock & Wilcox

Economizer. 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 approximately 1%.
