The effect of coal and additives ratio (b/v) and particle size on the calorific value (coal WebThe heating value or calorific value of a substance, usually a fuel or food, is the amount of heat released during the combustion of a specified amount of it. The calorific value is a characteristic for each substance. It is measured in units of energy per unit of the substance, usually mass, such as: kcal/kg, kJ/kg, J/mol, Btu/m³.Heating value is commonly …

WebCalorific value of char from branch feedstock pyrolysis was in range of 6,600 7,500 Kcal/Kg, while calorific value of char from co-pyrolysis branch and HDPE plastic was 8,300-11,000 Kcal/Kg. The optimum rise of calorific value was obtained from angsana HDPE plastic co-pyrolysis by ratio 25:75 which was 62.92%, or rose from 6,606 Kcal/Kg … WebFor an overall efficiency of 20%, one watt of mechanical power is equivalent to 18 kJ/h (4.3 kcal/h). For example, a manufacturer of rowing equipment shows calories released from "burning" food as four times the actual mechanical work, plus 1,300 kJ (300 kcal) per hour, which amounts to about 20% efficiency at 250 watts of mechanical output. pssm news
