Coal Mill - an overview ScienceDirect Topics

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.

The Coal mill performance monitoring - SlideShare

Nov 27, 2019  • In pulverized coal combustion, the ratio of coal to carrying gas is usually in the range of y = 0.5-0.6 kg/kg. • Assuming a coal density rc = 1.5 x 103 kg/m 3, and the density of the carrying gas as rg = 0.9 kg/m 3, the volume fraction of the coal can be shown to be very small, 0.036 % .
