Recovery and Use of Waste Heat - Midwest CHP Technical

Heat recovery technologies frequently reduce the operating costs for facilities by increasing their energy productivity. Recovering industrial waste heat can be achieved via numerous methods. The heat can either be "reused" within the same process or transferred to another thermal, electrical, or mechanical process. Ways of reusing heat locally include using combustion exhaust gases to preheat combustion

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.

Economizers of All Types | E-Tech Heat Recovery Systems

Economizers for Any Application. Hot flue gases pass over the finned tubes as boiler feedwater circulates inside the tubes. This preheats the feedwater, recovering otherwise wasted heat from the escaping flue gas. The higher temperature of feedwater entering the boiler contributes to smoother operation and quicker response to steam demands.

Economizer - Wikipedia

In this context they are often referred to as feedwater heaters and heat the condensate from turbines before it is pumped to the boilers. Economizers are commonly used as part of a heat recovery steam generator in a combined cycle power plant. In an HRSG, water passes through an economizer, then a boiler and then a superheater. The economizer also prevents flooding of the boiler with liquid water
