Coal Bunker Fire Prevention. Bunker Seal uses a manual spray nozzle and an air-powered pump mounted on a handcart to apply Soil-Sement®, a proven, gentle-on-the-environment polymer emulsion that seals the top of coal in bunkers to minimize oxidation, prevent spontaneous combustion and explosions.
Crushed coal is sent to the stockyard when coal bunkers are full. Stacking/reclaiming of coal is done by a bucket wheel stacker-cum-reclaimer moving on rails. The stacker-reclaimer stacks coal on either side of the yard conveyor. During stacking operations, the coal is fed from yard conveyors on a boom conveyor.
At present, this type of mill has been widely used in coal-fired power plants of China, and its structure is shown in Figure 1.

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 is usually received on railroad cars or barges. Conveyor belts transfer the coal as needed to mixing bins where the various types of coal are stored. The coal is transferred from the mixing bins to the coal crusher where it is pulverized to a preselected size between 0.15 and 3.2 mm (0.006 and 0.13 in.).
The raw coal from the bunker is supplied to the feeder where the primary air drives the coal and transferred to the pulverising mill. Central system. The pulverised coal from a mill is transferred through alternative flue gas to the cyclone separator, where the coal is separated and flue gas is sent back to the mill. ...

Coal feeders provide coal to the coal pulverizers (mills) where the coal is pulverized and dried. Dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness. Additionally, with less fuel moisture, more complete drying of coal can be achieved in the mill. This results in increased mill exit
