Pulverised Coal Combustion - an overview | …
Pulverised coal (PC) combustion is the most widely used technology for utility-scale power generation in the world. In PC boilers, coal is ground into fine particles (∼100 μm) and then injected with heated combustion air through a number of burners into the lower part of the furnace. Particles burn in suspension and release heat which is transferred into the steam cycle.
Pulverised Coal - an overview | ScienceDirect Topics
Pulverized coal (PC) systems are the most commonly employed methods of fuel combustion for power generation. Pulverized coal combustion includes wall-fired, tangentially fired, arch-fired, and roof-fired systems. Wall-fired and tangentially fired systems are the most common type of boilers.

Coal dust - Wikipedia
For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation. Pulverised coal is a significant dust explosion hazard, as large quantities are suspended in air for transfer from the mill to the power plant. Explosions have occurred …
