Direct firing coal mill plant is what is installed in most power generation facilities. The coal mill is operated as an air-swept mill and "blows" directly into the combustion zone of the steam boiler, via a pipeline connection. In case of an explosion, normally as consequence of ignition within the mill chamber, there will be
The intent of this project was to demonstrate that Alaskan low-rank coal, which is high in volatile content, need not be ground as fine as bituminous coal (typically low in volatile content) for optimum combustion in power plants.
