Boiler efficiency= Heat output / heat input *100. =steam flow (enthalpy of steam -enthalpy of feed water) / coal flow * gcv. For example if there is a 80mw boiler with 540 dig centigrade of main steam temperature, feed water temperature of 300 dig centigrade, coal flow 56 ton, gcv 4000 kcal/kg then the boiler efficiency will be =307(826.28-242.58)/56*4000=80%.

B&W's radiant boiler designs accommodate pulverized coal, including difficult-to-burn coals, natural gas and/or oil and combustible byproduct gases. Subcritical pressures range usually 1800 to 2600 psi (12.4 to 17.9 MPa) and superheater and reheater outlet temperatures as required, usually in the range of 1000 to 1050 F (538 to 566C).

17/3/2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
