Coal Pulverizer. A coal pulverizer is a mechanical device used to grind coal into fine powder for combustion in a furnace or boiler. It is an essential piece of equipment in power generation plants, where it is used to pulverize coal and feed it into the furnace to produce steam, which is then used to generate electricity.
Coal Pulverizers
An introduction to the nature of coal. J. Groppo, in Coal Combustion Products (CCP's), 2017 1.4 Coal pulverizing. In general, coal is transported and stored as fuel for use at as coarse a size as possible in order to minimize losses during handling and transport, moisture absorption, and spontaneous combustion, among other considerations.
Fire and Explosion Prevention in Coal Pulverizing …
Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will
