Jan 07, 2010· The numerical difference between the two is the latent heat of condensation of the water vapour in the combustion exhaust gas, which in turn depends on the hydrogen content of the fuel being burned.The difference is minimal for coal, significant for natural gas and largest for pure hydrogen fuel. So you have to do the conversion calculation for ...

using net calorific value (NCV). Domestic RPF con-sumption in 2011 was 240,000Mg/yr, which was com-pared to fossil fuels using NCV. B-C oil use, which has the same NCV, was equal to RPF use. In contrast, bituminous and anthracite were estimated at 369,231 Mg/yr and 355,556 Mg/yr, respectively. In addition, the reduction in CO 2 emissions due to ...

1. FUELS AND COMBUSTION

The difference being the latent heat of condensation of the water vapour produced during the combustion process. Gross calorific value (GCV) assumes all vapour produced during the combustion process is fully condensed. Net calorific value (NCV) assumes the water leaves with the combustion products without fully being condensed.

Cement Plants: Coal

Jun 01, 2011· Re: High fuel consumption. The difference between GCV and NCV looks ok as the South African coal haveing about 4 to 5 % hydrogen. SO i feel there is no big differnce. e.g if coal having 4.5 % hydrogen then the heat taken by water for steam is ~ 236 Kcal/Kg, if South African coal of you specs (GCV=6206 Kcal/Kg) is taken for calculation purpose of NCV than deduct 236Kcal/Kg from GCV.
