Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, or coal combustion residuals (CCRs), 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.

Nov 17, 2019 · Boilers are water-containing vessels that transfer heat from a fuel source (usually oil, gas, or coal) into steam. The steam is then piped to a point where it can be used to run production equipment, provide heat, to sterilize, to steam clean, among other tasks. There are two main types of boilers: firetube boilers and water-tube boilers.

Recycled Flue Gas - an overview | ScienceDirect Topics

Excess oxygen at burner inlets increases with increasing recycled flue gas for recycle flue gas containing 3.3% oxygen. When 71% of flue gas is recycled, 15.9% and 12.6% excess oxygen at burner inlets is obtained for wet and dry recycle oxy-fuel combustion respectively.
