Coal Pulverizer

The four most common types of coal pulverizers are: Ball-Tube Mills. This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills.

Types of pulverised coal firing system

Semidirect Firing System: A cyclone separator between the pulverizer and furnace separates the conveying medium from the coal. The hot primary air separated in the cyclone is used by the exhauster or primary air fan to push the coal particles, falling by gravity from the cyclone, through the burners into the furnace.

Pulverized Coal Firing Systems Testing & Diagnostics

Pulverized Coal Firing Systems. Slag caused by poor burner setup and pulverizer performance issues can be seen forming inside the furnace. Pulverized coal [PC] firing can pose unique challenges such as poor grinding performance, high carbon in ash, slagging problems and excessively high furnace heat fluxes due to combustion related issues.
