    • factors affecting gas boilers thermal efficiency

      Factors Affecting Gas Boilers Thermal Efficiency

      The thermal efficiency of a boiler is the percentage of the heat available from the fuel. The heat of gas boilers to produce hot water or steam mainly comes from the heat generated by fuel combustion. However, the fuel entering the boiler cannot be completely burned and released for various reasons, and the heat released by combustion will not be effectively used for the production of steam
