Economizers for Boilers | Recover Lost Enerygy

A boiler economizer is a heat exchanger device that captures the "lost or waste heat" from the boiler's hot stack gas. The economizer typically transfers this waste heat to the boiler's feed-water or return water circuit, but it can also be used to heat domestic water or other process fluids.

Boiler Economizer - brighthubengineering.com

Boiler Economizer is usually fitted to increase the efficiency of the boiler by increasing the heat recovery surface so that the maximum amount of heat is recovered from the burnt gases. This is achieved by heating the feed water to the boiler from the burnt gas before it leaves the furnace. In this article we discus the inspection carried out in the economizer and on it gas side of the boiler.

Blowdown Economizer Calculation - [PDF Document]

Blowdown Economizer CalculationSurface boiler blowdown is required to prevent foaming and priming because the blowdown maintains the proper amount of dissolved solids in the boiler. Surface blowdown is necessary but an energy hog. For example: a 10,000 #/Hr steam boiler operating at 125 psig requires a TDS level of 2,500 PPM or less.
