• Investigations of the Failure in Boilers Economizer Tubes

    May 01, 2013 · Economizer tubes are mainly used in fossil fuel power plants and are composed of a series parallel tube circuits. This part is located on the rear gas pass of the boiler below the rear horizontal superheater. Heat transfer in the economizer takes place in form of convection, while its operating temperature usually falls below 400 °C.Learn More
