INTRODUCTION TO BOWL MILLS: Coal is the one of the most dominating energy source because of its cost, availability and transportability. Pulverized form of coal has made modern steam generating units highly thermal efficient, reliable, safe and able to efficiently use of low-grade coals.
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done. There are many different standards and types of horsepower. Two common definitions being used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.
bution system on each mill supplies pulverized coal to eight coal nozzles, a total of 32 coal nozzles for the entire boiler. The exhauster discharge pressure is approximately 10 to 12" w.c. under full load operation. A single motor is connected to a common shaft for the mill and exhauster drive. This 600
