Pulverizer control system - The Babcock Wilcox Company

The coal flow from the pulverizer is transferred at 104 to a zero value from 106 if the swing valves are closed or the primary air flow is stopped, since these conditions immediately stop all coal flow from the pulverizer. FIG. 3A shows the logic of the pulverizer coal flow estimator 100.

Pulverized Coal Pipe Testing and Balancing

2016-5-3  Coal pipe F9 on pulverizer B was the only pipe that met the original plant fuel specification guarantee of 70% passing 200 mesh, which is far short of the 75% minimum we use. Even so, fuel fineness and fuel distribution overall was poor, and it resulted in slagging, fouling, and higher-than-desirable fly ash LOI.

US5241915A - Apparatus and method to improve

An apparatus and method to improve pulverizer operation and reduce nitrogen oxide emissions from furnaces which burn pulverized coal from at least one pulverizer. A duct type burner burns a fuel in the primary air which heats the primary air supplied to the pulverizers. The combustion increases the primary air temperature and improves the drying of the coal, thus improving the
