Coal Mill

The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from 175 to 22 with a typical value of 20 An air to fuel mass ratio of 18 produces a primary stoichiometric ratio of approximately 016, or 16% of the air necessary for complete combustion of the coal.

SEAL AIR BLOWERS

Seal air blowers eliminate leakage from pressurised air systems, typically in power generation plant coal mills Dust can enter the mill roller and cause problems where blowers are not used Guillotine dampers usually require seal air blowers to create a barrier of air at pressures above that of ordinary system operating pressure.
