Determining & Testing Boiler Efficiency for Commercial

Fuel-to-steam or fuel-to-water efficiency is a measure of the overall efficiency of the boiler. It accounts for the effectiveness of the heat exchanger as well as the radiation and convection losses. For space heating boilers and in the BTS-2000 testing procedure, this type of efficiency is called "thermal efficiency." It is an

Boiler - Efficiency

Boiler efficiency (%) = 100 (heat exported by the fluid (water, steam ..) / heat provided by the fuel) (1) Heat Exported from the Boiler to the Fluid. If a fluid like water is used to transfer heat from the boiler - the heat transfer can be expressed as: q = (m / t) c p dT (2) where. q = heat transfer (kJ/s, kW) m / t = mass flow (kg/s) m = mass (kg) t = time (s) c p = specific heat (kJ/kg o C) dT = temperature difference …
