Question

chlorific value of wood is higher than that of coal​

Answer 1

Answer:

Fuel Value of Wood The heating value of wood is about 21 MJ/kg (9000 Btu/lb) for ovendry softwood and 19.8 MJ/kg (8500 Btu/lb) for ovendry hardwood. The higher value for softwood is due to the higher lignin content. (Lignin has a much lower oxygen content than the carbohydrates it displaces.)
