احصل على السعرIf one wants in practice to refine the calculations, it is possible to calculate the calorific power and the useful output of the generators. The absorptive power or calorific power is the product of the volumic flow rate of gas by the NCV with constant pressure of fuel expressed in quantity of heat. Qv = Volumic flow rate of gas.

احصل على السعرAbstract Coal is generally analysed to determine its physical, chemical, thermal, mechanical properties like size consist, proximate values, ultimate values, calorific value and HGI. Calorific Value (CV) is an important thermal property of coal which indicates the amount of heat energy that could be liberated on combustion of a specific quantity.

احصل على السعرClarification: For calculating the GCV of the coal use the formula GCV=w (T 2T 1)/V, where w=weight of water and v=volume of fuel burnt. Substitute the corresponding values and we know that NCV is given by NCV=GCV [(M/V)587], M is the weight of the water obtained by steam. 2. Calculate the HCV and NCV of the coal for the following data.
احصل على السعرA common calculation is to calculate the gas consumption associated with supply heat from a gas boiler. If we then want calculate the cost of this gas, we multiply by a gas price. annual gas consumption = annual heat consumption / gas boiler annual gas cost = annual gas consumption * gas price
احصل على السعرabout 5% less than the gross calorific value (GCV) higher heating value (HHV) for solid and liquid fuels, while for gaseous fuels, the NCV is about 10% less. Default conversion factors NCV and emission factors (on a net calorific basis) are available for a list of default fuels as defined in the 2006 IPCC Guidelines.
