Hurst Boiler | StackMaster Increases Boiler Efficiency

The Hurst internal stack economizer is a factory-optional device that is designed to increase the operating efficiency of a boiler, cutting down on its operational costs over the lifetime of the boiler. Boilers operate by heating water to make steam, and using that steam for heating, processing or power generation.

Stack Economizer | Kemco Systems | Direct Contact Water

Stack Economizer Typical gas fired heaters and boilers send 20% (or more) of their consumed energy out the exhaust stack. This loss can mean that for every dollar spent on fuel, the boiler system returns only 65 to 70 cents worth of useful heat after transmission losses.

Economiser in Thermal Power Plant | Economiser | Electrical4U

Function of economiser in thermal power plant is to recover some of the heat from the heat carried away in the flue gases up the chimney and utilize for heating the feed water to the boiler. It is simply a heat ex-changer with hot flue gas on shell side and water on tube side with extended heating surface like Fins or Gills.
