Prediction of Calorific Value of Coal by Multilinear Regression …
WebCalorific value is the amount of heat energy present in food or fuel and which is determined by the complete combustion of specified quantity at constant pressure and in normal conditions. It is also called calorific power. The unit of calorific value is kilojoule per kilogram i.e. KJ/Kg. Water vapour is generated in the combustion process and ... WebIn this paper, a novel hybrid analysis was presented to predict the CV of coal. Pearson correlation coefficient (PCC) was used to remove correlations between variables in order to provide a suitable combination of input variables for ML models. phlegm in throat after eating or drinking

WebMay 13, 2024 · Abstract. The higher heating value (HHV) of 84 coal samples including hard coals, lignites, and anthracites from Russia, Colombia, South Africa, Turkey, and Ukrania was predicted by multilinear regression (MLR) method based on proximate and ultimate analysis data. The prediction accuracy of the correlation equations was tested by … WebFor calculation of GCV of fuel, we need to do an analysis of fuel and get the constituent of fuel on a weight basis. Based on the enthalpy of formation we can estimate the calorific value of the fuel. C+ O2 —- CO2 + 8137.5Kcal/kg of carbon. H2 + ½ O22—-H20 + 28905 Kcal/Kg of hydrogen.
