Boiler efficiency is a combined result of efficiency of different components of a boiler. A boiler has many sub systems whose efficiency affects the overall boiler efficiency. Couple of efficiency which finally decide the boiler efficiency are- combustion efficiency and thermal efficiency.

• ### Steam Generator Efficiency - Power Engineering

The benefits are efficiency related. The heat input required by the boiler to produce the required steam is only 1,149.1 Btu/lbm (1,474.1 - 325.0), as the feedwater temperature is much warmer.

• ### Rankine cycle - Wikipedia

The efficiency of the Rankine cycle is limited by the high heat of vaporization of the working fluid. Also, unless the pressure and temperature reach super critical levels in the steam boiler, the temperature range the cycle can operate over is quite small: steam turbine entry temperatures are typically around 565 °C and steam condenser temperatures are around 30 °C.

• ### How to calculate boiler efficiency by Direct Method

Nov 24, 2016· Boiler Efficiency:-Thermal efficiency of boiler is defined as the percentage of heat input that is effectively utilized to generate steam. There are two methods of assessing boiler efficiency. 1) Boiler Efficiency by Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel.
