• Return Condensate to the Boiler

    Return Condensate to the Boiler When steam transfers its heat in a manufacturing process, heat exchanger, or heating coil, it reverts to a liquid phase called condensate. An attractive method of improving your power plant's energy efficiency is to increase the condensate return to the boiler.Learn More

  • Chemical Treatment Requirements for Condensate Systems

    Condensate Return Introduction. Condensate (water or condensed steam) reduces the quality of the steam but is too high value to discard. Condensate can contain up to 20% of the energy required to make the steam in the boiler. Maximize the amount of condensate that is returned to the boiler to save both energy and water treatment chemicals.Learn More
