Calculating Boiler Efficiency  Forbes Marshall
The indirect efficiency of a boiler is calculated by finding out the individual losses taking place in a boiler and then subtracting the sum from 100%. This method involves finding out the magnitudes of all the measurable losses taking place in a boiler by separate measurements.

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 …

Water tube boilers blow fire tube boilers away in regards to efficiency. Water tube boilers require far less water to function, and at the same time, they also have a higher rate of steam generation than fire tube boilers. This helps to reduce the amount of water and fuel necessary to make a water tube boiler run compared to the alternative option.
