coal. Many cyclone boilers currently operate the cyclone barrels substoichiometrically to reduce NOX emissions. The balance of air required to complete combustion is provided through overfire air ports. The extent of staging is limited by the minimum heat release in the barrel that is required to keep the slag molten and free flowing.

The Cyclone Steam Boiler provides for exceptionally high efficiencies, lower fuel costs, and extremely rugged construction.
Cyclone boiler, burns crushed coal. 70 to 80 percent of the ash is retained as boiler slag. The rest of the ash leaves as fly ash. If the ash fusion temperature is less than the furnace temperature then that type of furnace is called a wet bottom furnace. Steps in the process. Both boiler types have a solid base with an orifice that can be ...
A cyclone boiler windbox typically has significant secondary air flow … ash fusion temperature and iron content) in with the primary coal to help avoid problems. … Robust Damper design for long life and operation can be seen in the pictures.
Cyclone boilers burn crushed (but not pulverized) coal in large (e.g., 10-ft dia.) cyclone barrels and send hot (e.g., 3200–3550°F or 1760–1950°C) gases into the furnace and then convective pass. Cyclone boilers are designed to maximize the production of slag from the inorganic constituents in fuel; inorganics are managed in this manner.
