Applying the Fundamentals for Best Heat Rate Performance of

In other words, if a boiler firing Central Appalachian coal with a 12,000 Btu/pound HHV and 10% ash has a 15% flyash LOI, the losses due to LOI when calculated by the ASME code will come out real close to 1.5 % in efficiency loss of the boiler for the heat loss component attributed to carbon in ash. If the steam plant is operating at a heat


key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units
