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.
Coal type determines the composition of coal and it reflects the degree of oxidation during coalification. Based on the van Krevelen diagram (van Krevelen, 1993), coal consists of three key material groups including vitrinite, liptinite and inertinite, which are composed of distinct constituents called macerals. Table 14.2 compares the key characteristics of coal macerals …
The coal to be pulverized is delivered from a bunker 1 to a coal metering hopper 3 via a supply conduit 2. The metering hopper 3 is controlled, in the manner to be described below, so as to deliver measured quantities of coal to a roller mill 5 via conduit 4. The air which entrains the coal dust produced by mill 5 is provided by a blower 9.
Air Swept Coal Mill Diagram Air Swept Coal Mill Working Principle First, the raw coal is fed into the feed chute by the feeding device. Then, the hot air with a temperature of about 300 ℃ enters through the air intake pipe and begins to dry the raw coal while they are falling. After that, the raw coal will be sent into the mill chamber.
