1. energy performance assessment of boilers - Bureau of Energy
Basically Boiler efficiency can be tested by the following methods : 1) The Direct Method : Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel. 2) The Indirect Method : Where the efficiency is the difference between the losses and the energy input.
