vortex burner. The coal is fed from the storage area to a crusher that reduces the lignite into particles of approximately 0.25 inch in diameter or less. Crushed lignite is partially dried in the crusher and is then fired in a tangential or vortex pattern into the cyclone burner. The temperature within the burner is hot

lowest uncontrolled dust emissions due to the large lump feed, the relatively low air velocities, and the slow movement of material through the kiln. In coal-fired kilns, the properties of the limestone feed and the ash content of the coal can significantly affect PM emissions. Some sort of particulate control is generally applied to most kilns.

Our Coarse Coal Centrifuge range are horizontal vibrating-basket style machines that use centrifugal force to separate surface water from coal. They can treat material from -50mm to +0.5mm. They can also decrease feed moisture down from 18–25% to produce surface moisture of the product to be as low as 2–9%, depending on the particle size ...
