If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air. Even in routine mill shutdowns, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restartedget price
The coal in the As Received condition is first pulverized in grinding mills to obtain Pulverized Fuel (pf) or Pulverized Coal. The resulting coal dust is blown into the combustion chamber or furnace section of the boiler. In modern boiler plant the coal is required as a fine dust in order to achieve combustion rates similar to those of oilget price
Jan 21, 2004 Pneumatic conveying systems offer enormous advantages: flexibility in plant layout, automatic operation, easy control and monitoring, and the ability to handle diverse materials, especially dangerous, toxic, or explosive materials.
