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]
ISO reproducibility values for C(db) 1.00% and GCV(db) 300J/g, converted to as-received basis, are used in the calculation of Uncertainty. Fuel Ratio = Fixed Carbon / Volatile Matter Ballast = Ash(ar) + Total Moisture; Hydrogen in Coal: Refer to ASTM 3180 / ISO 1170
H. Liu, in Small and Micro Combined Heat and Power (CHP) Systems, 2011. 5.2.3 Calorific value. The calorific value of a fuel is the number of heat units evolved when unit mass (or unit volume in the case of a gas) of a fuel is completely burned and the combustion products are cooled to 298 K. This definition of calorific value includes the provision that the products of combustion are cooled ...

Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus:. A known amount of the fuel is burned at constant pressure and under standard conditions (0°C and 1 bar) and the heat released is captured in a known mass of water in a calorimeter. If the initial and final temperatures of the water ...
Compared with coal and diesel, biomass energy has such advantages as renewability, high calorific value, low pollution, zero carbon emission, high density. Generally, biomass energy are utilized in such forms: biogas, ethyl alcohol, biodiesel, and biomass molding fuel.
Nov 04, 2011· KCAL/KG CLINKER WITH GCV/NCV. DO WE HAVE MORE KCAL/KG CLINKER IF WE TOOK THE BASE AS GCV OF COAL & LESS WITH NCV OF COAL ? IF YES, WHY ? ALSO IN CASE OF GCV THE COAL CONSUMPTION WILL REDUCE OR WILL REMAIN THE SAME ? Reply. Know the answer to this question? Join the community and register for a free guest account to post a reply.
Average specific energy requirement (A) = 1325 k Cal/ kg of clinker production Mid value of GCV for grade G-4 (B) = 6250 kcal/ kg of coal Specific coal consumption = (A x 1000)/ B -------------(i). = (1325 x 1000)/ 6250 = 212 kg coal /ton of clinker 7. 0 Normative requirement of coal for sponge iron industries:

Since 1961, the average gross calorific value of the domestic thermal coal supply has almost halved to 3300 kcal/kg. This decline will continue as the share of inferior Indian coal is expected to increase progressively. Consequently, coal consumption per unit power generation and hence ash amount and emissions are observed to be continuously rising.
