= As Received Carbon x 3.667 x [10,000/NCV(p)] in kJ/kg = As Received Carbon x 3.667 x [2388.46/NCV(p)] in kcal/kg Standard Uncertainty of CO 2 Emission Factor (tCO2/TJ)

Calculation of Calorific Value of fuel..

NCV of Fuel = GCV (584 ((9*H2%+M%)/100) =10430 (584((9*12+0)/100)) = 10497.2- 630.7 = 9866.5 Kcal/kg. Impact of CO formation in Fuel: In normal combustion Carbon is converted into CO2, but when there is deficit of oxygen CO is generated as below:-C+ O2 —- CO2 + 8137.5 Kcal/kg of carbon. 2C+O2—-2C0 +2430 Kcal/kg of carbon

Calorific Value of Coal 21092012

Low rank coal is low in carbon and high in oxygen while high rank coal is high in carbon and low in oxygen. High carbon coal has high heat energy or calorific value. 3. Definition of Calorific Value (CV) Calorific Value/ CV / heat of combustion (∆H c 0) is defined as the amount of heat energy released on burning a unit mass of coal in a bomb

2020-7-13 For typical bituminous coal with 10% M and 25% Volatile Matter, the differences between gross and net calorific values are approximately as follows: 260 kcal/kg 1.09 MJ/kg 470 Btu/lb Power Generation 1 MWh = 3600 MJ 1 MW = 1 MJ/s 1 MW (thermal power) [MWth] = approx 1000 kg steam/hour 1 MW (electrical power) [MWe] = approx MW(thermal power) 3

Calculate H.C.V. and L.C.V. using Dulong formula.

A sample of coal has following composition by mass C = 70 %, O = 8 %, H = 10 %, N = 3 %, S = 2%, Ash = 7 %. Calculate H.C.V. and L.C.V. using Dulong formula [Difficulty level-high] Solution: HCV = 1/100 [8080 C+34500 (H-O/8) +2240 S] = 1/100 [8080 + 70+34500 (10-8/8) +2240 X 2] = 1/100 [565600 + 34500 (10-1) X 4480] = 1/100 [565600 + 310500 + 4480]
