Seyler''s Formula Various parameters of coal can be estimated from the Ultimate Analysis and Calorific Value determinations, using Seyler''s formula, and other similar calculations ( Dulong''s formula). ISO 1928 2009 Determination of Gross Calorific Value
Explanation: For calculating the components of coal and the petroleum the dulong''s formula is applied. So, the dulong''s formula is applied for both solids and liquids and not for gaseous. 6. Modification of the dulong''s formula can be done by considering the _____ a) latent heat b) heat c) fuel state
Seyler''s Formula Various parameters of coal can be estimated from the Ultimate Analysis and Calorific Value determinations, using Seyler''s formula, and other similar calculations ( Dulong''s formula). ISO 1928 2009 Determination of Gross Calorific Value
Dulong''s formula is but one of several that predict the heating value of coal based on its elemental analysis, Lots of hydrogen and carbon lead to lots of heat. Presence of oxygen leads to opposite, less heat. The numbers are the coefficients in the equation for combustion heat. Note that oxygen has a negative coefficient.
Values calculated using the Dulong formula show deviations from the value determined experimentally for lignite and subbituminous coal due to their high oxygen content (Hosokai et al 2016). ...
