Apart from these efficiency, there are some other losses which also play a role while deciding the boiler efficiency and hence need to be considered while calculating the boiler efficiency. However, the most important factors need to be considered are boiler combustion efficiency and boiler thermal efficiency.

Read MoreJan 11, 2005· If the only information you have is fire-side data, then you can calculate combustion eff. And while that's important, it's not boiler eff. To calculate boiler eff, you need to determine the net heat out, and divide it by the heat input for the same time period. The calculation itself is dead simple.

ENERGY PERFORMANCE ASSESSMENT OF BOILERS Bureau of Energy Efficiency 1 1.1 Introduction Performance of the boiler, like efficiency and evaporation ratio reduces with time, due to poor combustion, heat transfer fouling and poor operation and maintenance. Deterioration of fuel quality and water quality also leads to poor performance of boiler.

Read MoreTo give the efficiency as a percent, we multiply the previous formula by 100. Note that, η th could be only if the waste heat Q C will be zero. In general, the efficiency of even the best heat engines is quite low. In short, it is very difficult to convert thermal energy to mechanical energy.The thermal efficiencies are usually below 50% and often far below.

Read MoreAug 09, 2018· One way of calculating is to calculate boiler efficiency, turbine efficiency and generator efficiency and multiply them all to arrive overall plant efficiency. The efficiency of the steam turbine power plant depends on the type of fuel used in the boiler. The efficiency of coal-powered plants ranges from 30–42% depending on the pressure and temperature of the steam.
