According to the actual situation, disengage the automatic grinding group when necessary, manually control the amount of coal, stabilize the load and steam temperature and vapor pressure. Immediately contact the coal handling duty officer to check the coal level of the original coal hopper to determine whether the original coal hopper is empty;

When the coal vertical roller mill is not tripped and the raw coal enters the coal vertical roller mill intermittently, the coal vertical roller mill must be cut to manual adjustment in time, strictly control the outlet temperature not to exceed 80 ℃, and put in fire-fighting steam when necessary to avoid air dust caused by the broken coal The ratio imbalance causes dust explosion in the coal vertical roller mill;

Strengthen the combustion adjustment, put oil in time for unstable combustion, start the backup coal vertical roller mill in time according to the load, and pay attention to the change of the main steam pressure and main steam temperature of the boiler.
