Jamming of the coal chute from the bunker due to high moisture in the coal, foreign material at raw coal inlet to feeder, etc plant responses the boiler fuel input coming down due to coal flow hangup the mill slowly gets unloaded,The reasons for coal hangup to mills can be many, jamming of the feeder, like large raw coal size.
Conventional esp has problems such as backward power source technology, insufficient design targeting, ultralow emission power plants have made some upgrading to the esp system, which makes it less effective for pm control in response to these problems, and high operating temperature, thereby increasing its control effect on pm .
Nov , and mesh a coal sample passing through a mesh screen indicates optimum mill performance the mill wear and the power consumption are increased if the value is exceeded values lower , fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at , specifically, .
Bulk density, specific density, feed size as f and maximum chunk size, desired mill tonnage capacity dtph, product size as p and maximum and finally the type of circuit openclosed ,The basic parameters used in ball mill design power calculations, characteristics, bond work index, rod mill or any tumbling mill sizing are material to be ground, operating solids or pulp density.
Ash and volatile matter, while the fixed carbon is found by difference ultimate analysis gives the elemental composition of the coal other methods like macarel analysis is also used ,Properties of coal coal properties are evaluated by different methods the most commonly used methods are proximate and ultimate analysis of the coal proximate analysis gives the moisture.
