Feb 12, 2021 · Because of this there is a loss of heat around 17500 kcal/hr .Calculate the extra fuel consumption in a day to compensate this loss. Consider coal GCV & boiler efficiency 4500 kcal/kg & 90% respectively. We have, Heat loss in terms of fuel = Heat loss / (Fuel GCV X Boiler efficiency) = 17500 / (4500 X 0.9) =4.32 kg/hr
Read MoreWhen choosing a heating boiler, you need to take into account how simple and convenient this or that option is in operation, as well as what kind of maintenance it requires. If you do not want to regularly clean the boiler, then it is better to opt for an automated product, although it will cost significantly more.

Its not just the boiler, its how it gets used. My horrible 73% efficient back boiler has a flue that passes up through the house. When the exhaust gases pass out of the chimney at the top they are cold, so much of the 27% of the so called lost heat probably ends up in the house anyway. many combi boilers cycle when the hot tap is turned on as well.

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.

Nov 11, 2016 · KompareIt says that steam boilers running on oil have a minimum AFUE of 82%. A steam boiler running on gas, meanwhile, would have a minimum of 80%. Hot water boilers have a minimum of 82% for gas models and 84% for models that run on oil. Energy.gov says boiler vs. furnace energy efficiency can also be compared by noting certain equipment features.
