  • Combustion Air Pre-Heater - CleanBoiler.org

    Heating combustion air can raise boiler efficiency about 1% for every 40F in temperature increase. The most common way to preheat the air is with a heat exchanger on the flue exhaust. The heat exchanger can be either air-to-air or air-to-liquid-to-air. Combustion air pre-heater technology on large coal-fired boilers dates back to the early 1900 Get Price
