The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from to with a typical value of An air to fuel mass ratio of produces a primary stoichiometric ratio of approximately, or 16% of the air necessary for complete combustion of the coal.
01/09/2020#0183;#32;Since the primary air flow is reduced and the stored coal powder is increased, the opening of the mixed air regulating value is increased (Fig. 7(d)), the outlet pressure of the coal mill is decreased (Fig. 7(h)) and the outlet temperature of the coal mill is gradually reduced (Fig. 7(i)). Until the amount of stored coal reaches its upper limit value, the primary air channel is blocked and the coal powder
