gives boiler designers an edge during the proposal and contract stages. Here is how to predict fly ash and bottom ash combustibles in order to compute carbon loss in a boiler. In boilers with pulverized firing systems, about 80% of the ash in coal being fired is carried as fly ash. The other about 20% get collected as bottom ash.

Fly ash (FA), also known as pulverized fuel ash, is a fine powder obtained from the combustion of powdered coal in an electricity generating plant. Temperature may exceed 1600°C during the burning process and may melt most of the inorganic materials present in the coal. The inorganic matter present in it gets fused during the combustion of coal.
