• ### Energy value of coal

The calorific value Q of coal [kJ/kg] is the heat liberated by its complete combustion with oxygen. Q is a complex function of the elemental composition of the coal. Q can be determined experimentally using calorimeters. Dulong suggests the following approximate formula for Q when the oxygen content is less than 10%: Q = 337C + 1442(H O/8) + 93S,

• ### Direct and Indirect efficiency in boilers

Direct Method. Indirect Method. Direct method: Direct method is quick method for boiler efficiency calculation, In this method, Percentage of total heat output vs heat input is calculated to establish boiler performance. Boiler Efficiency = Heat output / Heat Input X 100. Or Boiler Efficiency = Q X (h2 – h1) / (q X GCV.
