  • Air Preheating System APH

    When installing new steam boiler systems with economisers, air preheating is the ideal solution for increasing efficiency, particularly in cases where the integration of a flue gas condenser is impractical for process reasons. The Bosch air preheating system is available for single or double flame tube boilers with duoblock burners.

  • US3835650A - Steam air preheater for a steam boiler system ...

    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.
