optimized good boiler efficiency. Boiler efficiency can be measured by two method, direct method and indirect method. Both methods give a different result. Direct method did not include any losses for calculating boiler efficiency, while indirect method includes all the heat losses from a system to find boiler efficiency.
Not only the thermal efficiency of coal fired boilers, even the thermal efficiency of gas fired boilers and oil fired boilers, the thermal efficiency of waste heat boiler and biomass boiler, are high and low, which is largely due to technology, design, different materials of different manufacturers, But also has a great relationship with the boiler installation and operation of the boiler.
Sep 23, 2009 · Efficiency figure depends upon the type of boiler as well as on the type of fuel and it’s constituents. For example, efficiency of a Bagasse fired boiler is about 70% where as that of oil fired boilers is about 85 %. Higher moisture content in Bagasse reduces it’s efficiency. So better criterion is efficiency based on LCV or NCV.
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. Boiler efficiency calculation methods. The overall boiler efficiency depends on many more parameters apart from combustion and thermal efficiency.
The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Excess air to achieve highest possible efficiency for some common fuels: 5 - 10% for natural gas; 5 - 20% for fuel oil; 15 - 60% for coal

done. The plant is having capacity of 2649 MW from coal and 829 MW from gas-based station. More has been focused on heat losses in coal fired steam generator, economizer, air preheater and loss Marshal Yard to steam generator. The methods used for efficiency of boiler is direct and indirect
The efficiency of modern condensing gas boiler can be over 100% as heat is extracted from the incoming air. A traditional brick built coal fired boiler may only be 50% efficient. Combustion Efficiency v Boiler Efficiency. A combustion or flue gas analyser is used to measure the efficiency of the combustion process within a boiler.
Typically for a natural gas boiler oxygen readings may be in the range 3% to 5%, for an oil boiler 5% to 8% and for a coal fired boiler 8% to 10%. The combustion efficiency of modern condensing gas boiler can theoretically be over 100% as heat is extracted from the incoming air. A traditional brick built coal fired boiler may only be 50% efficient.
The final boiler efficiency is the sum of the losses plus any unaccounted for losses. Staff estimated 1 percent for unaccounted for losses to include any radiative and convective losses. Thus, the final boiler efficiency equation is given below. Eq-12
