This Efficiency Facts Booklet is designed to clearly define boiler efficiency. It will also give you the background in efficiency needed to ask the key questions when evaluating efficiency data, and provide you with the tools necessary to accurately compare fuel usage of …File Size: 296KB
The gross calorific value of the fuel includes the energy used in evaporating this water. Flue gases on steam boiler plant are not condensed, therefore the actual amount of heat available to the boiler plant is reduced. Accurate control of the amount of air is essential to boiler efficiency:
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.
The average values for Fuel-to-Steam efficiency are typically between 80-85%. To achieve the upper end of this metric, manufacturers have incorporated advanced computational fluid dynamics (CFD) modeling to optimize the design of components such as boiler tubes, furnace shape, and …
Boiler efficiency (%) = 100 (heat exported by the fluid (water, steam..) / heat provided by the fuel) (1) Heat Exported from the Boiler to the Fluid If a fluid like water is used to transfer heat from the boiler - the heat transfer can be expressed as: q = (m / t) cp dT (2)
