pounds of coal per hour and this is often referred to as the mill capacity. We prefer to discuss coal throughput as one of the three major components of capacity (Hardgrove grindability and fineness are the other two). Take one version of a typical correction curve for a pulverizer rated at 125,000 lb/hr as shown in Figure 2 for an HGI of ...
The raw coal is delivered to the feeding device of the coal mill, and at the same time the hot air with a temperature of about 300°C also enters the feeding device through the air inlet pipe, where the raw coal containing moisture starts to exchange heat.

Pulverizer - Wikipedia. A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example a pulverizer mill is used to pulverize coal for . Relationship between coal size reduction and . 1. Introduction.
Pulverizers / Mills. Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW. B&W's pulverizers, found at power stations throughout the world.
Coal Pulverizer Inlets and Outlets. Louvres (nozzle ring) around the outer perimeter of the grinding table allow hot gas to flow into the grinding mill through the mill base. Some of the pulverized coal is transported from the base of the mill up to the classifier by the hot gas stream i.e. the coal is transported pneumatically.

today, there normally exists a combustible coal/ air mixture in the burner lines and pulverizer equipment. Hence there is the continual danger of fires and, under certain conditions, explosions. Proper design and operation of the pulverized coal burners protects the pulverizing system from ignition from the furnace fire.

Combustion of coal particles beneath the grinding zone is not a serious problem, as long as the mill is in operation. But if a mill trips or a boiler has a main fuel trip, then fires in the pyrites zone (beneath the grinding zone) are the most common cause of pulverizer "puffs," in our experience. ... of the presented mathematical model in ...

Thermocouples or RTD's are normally part of the control system for mill operation. However, they are a relatively insensitive means for detecting pulverizer fires. At best, they warn of impending trouble only a few minutes before it actually occurs, and in some cases, do not even detect a significant temperature rise before a fire or explosion ...
