  • Air preheater

    Air preheater. The air preheater uses the hot feed water to preheat the combustion air and obtain a cool water flow in the return. This cold flow can now be used in an additional economiser bundle to further reduce the flue gas temperature. This increases efficiency by 2% points, or flue gas temperatures that are roughly 40K lower.

  • US3835650A - Steam air preheater for a steam boiler

    A steam boiler system includes a steam air preheater disposed in inlet ducting for preheating intake air. A boiler feed pump provides high-pressure water to a boiler which in turn produces steam to drive a main turbine. Exhaust flow from the turbine is routed directly to a main condenser, with the exception of a small extraction flow which is used to drive a boiler feed pump turbine.
