Cyclone Boiler - an overview | ScienceDirect Topics

Combustion occurs at very high temperatures: 3200°F to 3550°F (1760–1950°C). The fuel for cyclone boilers is typically a bituminous coal prone to slagging; it may be blended with other coals and/or petroleum coke, biomass, or other fuel materials. Some cyclone boilers are fired with subbituminous coals, while others are fired with lignites.

What the Power Industry Should Know about Cyclone Boilers

A cyclone-fired boiler uses large crushed coal particles (typically 4 mesh size), which must be burned at a slower rate than PC 1 to complete the combustion process. This slower rate of combustion requires a unique burner design. 2 The burner's assembly is a long, round chamber (6- to 10-ft. diameter) formed by water wall tubes attached to
