For a fuel of composition C c H h O o N n, the (higher) heat of combustion is 418 kJ/mol (c + 0.3 h 0.5 o) usually to a good approximation (±3%), though it can be drastically wrong if o + n > c (for instance in the case of nitroglycerine ( C. 3H. 5N. 3O. 9) this formula would predict a heat of combustion of 0 ).

utilized to generate steam. There are two methods of assessing boiler efficiency: 1) Direct Method: In this method the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel. 2) Indirect Method: In this method the efficiency is the difference between the losses and the energy input.
