Fire Detection Methods for Coal Pulverizer Systems

the coal feed system will confuse detection. The problem of outside entrainment can be eliminated by measur- ing the CO differential across the mill. Comparing the inlet and outlet CO allows the system to alarm only when CO is generated in the mill.

Fire Protection Guidelines for Handling and Storing PRB Coal

The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from 1.75 to 2.2 with a typical value of 2.0. An air to fuel mass ratio of 1.8 produces a primary stoichiometric ratio of approximately 0.16, or 16% of the air necessary for complete combustion of the coal.
