For calculation of GCV of fuel we need to analysis of fuel and get the constituent of fuel on weight basis. Based on the enthalpy of formation we may estimate calorific value of fuel. C+ O2 —- CO2 + 8137.5Kcal/kg of carbon. H2 +.5O2—-H20 + 28905 Kcal/Kg of hydrogen. S +O2—SO2+ 2181 Kcal/kg of Sulphur.
GCV (ARB) = GCV (ADB) X (100-TM)/(100-IM) e.g. ADB 6300 x (100-18)/(100-12) = 5870 GAR . NAR (kcal/kg) = GAR (kcal/kg) – 50.7H – 5.83TM . NAR is NCV ARB. GAR is GCV ARB. H = Hydrogen is usually in DB or DAF and needs to be converted to ARB . H is assumed as 5.4 DAF (regional variance used in lieu of Ultimate Analysis) ...
ADB – Air-Dried Basis. In coal sample analysis, ADB neglects the presence of moistures other than inherent moisture while DB (dry-basis) leaves out all moistures, including surface moisture, inherent moisture, and other moistures. ARB – As-Received Basis. It provides a rough estimate of the heating value of coal. Is Gar and GCV same?
Where: GCV ARE = Gross Calorific value of coal after moisture correction, PCV ADB = Gross Calorific Value at Equilibrated Condition 60% RH and 40° C), TM=Total moisture, M eq =Equilibrated Moisture at 60% RH and 40° C ii (b): Till CERC specifies any norm, a margin of 85-100 IkCal/kg in GCV for pit head station and a margin of 105-120
ARB is the most widely used basis in industrial applications. Ash content - Ash content is the non-combustible residue that remains after coal is burnt. Ash reduces handling and burning capacity, affects combustion efficiency and boiler efficiency and therefore increases handling costs. ASTM - American Society for Testing and Materials.
The lower calorific value doesn't include the energy released in condensing water. This is why a gross calorific value is higher than a net calorific value. HHV = water vapour is condensed = more heat is recovered. LHV = water vapour remains as vapour – less heat is recovered. The reason for the distinction is that water vapour in ...
