  • 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.

  • 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.

  • STEAM AIR PREHEATER FOR A STEAM BOILER SYSTEM -

    The steam air preheater 60 picks up heat energy in steam air preheater 60 from steam coming from boiler feed pump turbine 50. Since the temperature of the flow in conduit 51 may not be much greater than the temperature of the intake air, steam air preheater 60 requires a highly efficient heat transfer surface.
