systems, explosive mixtures are minimized by keeping the air and fuel separate until they are combined at the point of combustion. In the air-conveyed direct-fired coal pulverizing system, used extensively in the industry today, there normally exists a combustible coal/ air mixture in the burner lines and pulverizer .

Earliest known coal feeder, representing innovations that influenced nearly all industries using coal-fired boilers A variety of mechanical feeders, including drag-chain conveyors and rotary pocket feeders, historically have been used to volumetrically control the flow of fuel to coal pulverizers .

As one of the world's leading coal pulverizer manufacturers, Williams has the most advanced direct fired coal and pet coke pulverizing system in the field today. Design features of our coal pulverizer emphasize improved system reliability, constant product size control, and reduced energy requirements.

Dry coal that is allowed to remain in the pulverizer system can spontaneously ignite. Raw coal to the pulverizer must be uninterrupted and controllable. Precise feeder control and minimal stoppages above and below the feeder are crucial. Hot smoldering or burner raw fuel anywhere in the pulverizer system is considered serious.
