Coal Extraction System with Pulse Jet Bag Filter
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 8
Abstract
Air pollutants are added into the atmosphere from variety of sources that change the composition of the atmosphere and affect the biotic environment. Because of the presence of high amount of air pollutants in the ambient air, the health of the population and property is getting adversely affected. In Mettur thermal power station (MTPS) primary fuel is coal. The requirement of coal per day 14000 tons. The coal transported through railway wagons has been unloaded in wagon Tripler. From the wagon Tripler During the coal unloading activity, enormous coal has been extracted from the coal transfer chute, which in turn polluted the entire coal handling area. Hence, to tide over the problem, it is necessary to go for effective coal control measures in MTPS. In pulse jet bag filter, the coal that is disc lodged from a row of bags may be picked up by the adjacent row of bags as the latter is under suction. The coal may remain is suspended condition- especially if it is light and / or fine - the reverse upward gas flow not allowing the coal to settle in the hopper. This phenomenon is called fluidization of coal. The coal particles are sucked from the suction point and allowed to the bag filter. The air from the suction point is made to fall on the baffle plate and then it is allowed to the bags. This air goes to the bottom of the bag, then it comes out on the top of the bag there all the coal particles are collected on the outer surface of the bag. Then the cleaned air is sent out through the chimney.
