  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 …

  Performance of Boiler: Efficiency, Power, Heat Losses and

  May 12, 2020· We know that the efficiency of a boiler is the ratio of heat used in producing steam to the heat released in the furnace. Also, heat utilised is always less than the heat liberated in the furnace. The difference of heat liberated in the furnace and heat utilised in producing steam is known as heat loss in the boiler.
