Fly ash - Wikipedia

Seventy-five percent of the fly ash must have a fineness of 45 µm or less, and have a carbon content, measured by the loss on ignition (LOI), of less than 4%. In the US, LOI must be under 6%. The particle size distribution of raw fly ash tends to fluctuate constantly, due to changing performance of the coal mills and the boiler performance.

Fluidized Bed Boiler PT. ANUGRAH ENERGI INDONESIA % bed boiler

Waste gases produced during fluidized bed combustion contain a significantly smaller percent of sulphur and nitrogen oxide contents compared to conventional combustion. The principles of fuel burning in a fluidized bed also provide suitable conditions for burning a wide range of fuels such as coal, biomass, sewage treatment plant sludge, separated municipal waste, and others.
