To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

Fire and Explosion Prevention in Coal Pulverizing Systems

Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal

The Role of Coal Characteristics in Boiler Operation

Pulverizer capacity is particularly sensitive to coal moisture. An increase in coal surface moisture from 5% to 14% can reduce the output of the pulverizer to 74% of its original capacity. The Riley Stoker Corporation has found it desirable to use crusher dryers ahead of its ball tube mill pulverizers to overcome this problem.

IMPROVE YOUR PULVERIZER PERFORMANCE

4. Lower air flow results in better fineness less erosion. 5. Lower air flow can result in more pyrites, but fewer burner eyebrows. 6. Lower air flow means and a greater tendency to plug with wet coal. 7. Lower air flow leaves more reserve fines in the pulverizer. 8. Also note that lower air flow leaves a deeper bed depth of coal, and thus a ...
