Cyclone Boiler - an overview | ScienceDirect Topics

Cyclone boilers burn crushed (but not pulverized) coal in large (e.g., 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.

Hydrocyclones – Hydrocyclone Separator

Principle of operation. Centrifugal forces are the effective principles of the separation processes in the hydrocyclones. The suspended particles are thrown radially to the outside. Because of the magnified field of force, high settling rates, fast separation and high load are obtained. Flow promoting designs ensure high accuracy of separation.

Coal preparation plant - Wikipedia

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
