Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.

A Middle Kittanning seam coal was pulverized to 80% passing 200 mesh (pulverized coal or "PC" grind). The coal was fed into the combustor at two rates: 92.3 kW (designated "low fire") and 124.5 kW (designated "high fire"). The combustion air was monitored by the oxygen concentration in the flue gas stream. The excess oxygen was held at either 3% (designated "low air") or 5.5% ...
