Fuel consumption calculation of oil-fired boiler - FAQ

Feb 22, 2021 · Taking a 10-ton oil-fired boiler as an example, its heating power is 7MW, assuming that the combustion heat value of a certain oil fuel is 42Mj/kg, and the boiler fuel efficiency is 95%, it can be concluded that a 10-ton boiler needs oil consumption per hour=3600 *7/42/0.95, about 630kg.

Boiler Efficiency - an overview | ScienceDirect Topics

The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.
