When the mill pulveriser is at low load, the pulverised coal at the outlet of the mill pulveriser is excessively lean as the air ratio is too high against coal. In this case, coal or oil must be increased to reach stoichiometric air-fuel ratio. Conventionally, the minimum load of coal-firing without oil support is limited to 30%-50% load.
