The amount of coal is regulated according to the needs in the boiler combustion chamber furnace. The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.Several types of feeders can be used in a crushingprocess system. They are selected to suit the material, feed rates and pre-sorting. The feeder decides the magnitude of the load on the crushingprocess system. Therefore, the handling system load condition and thereby its performance is controlled by the feeder.the combustors, with front and rear wall feed systems adapted to the distinct needs of this type of boiler. 3. Stoker Boilers are still in common use for single and multiple fuel applications. The Stock Batch Scale pro-vides a precise flow of coal at exactly the usage rate and totalizes the quantity over time for accounting and economic purposes.

BENSON, Senior Engineer Fuel Burning Product Development and C.A. PENTERSON, Manager . enter one or both ends of the mill from a crusherdryer or feeder. As the mill rotates, the balls cascade and pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to .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.Since the first application using an MPS mill to process pulverized coal in Germany in the mid 1960s, there have been over 2,000 different MPS mill installations operating in coal-fired power plants worldwide. As one of the most popular coal pulverizers in the utility industry, the MPS mill was first introduced into the US in the early 1970s.
