A baghouse, also known as a baghouse filter, bag filter, or fabric filter is an air pollution control device and dust collector that removes particulates or gas released from commercial processes out of the air. Power plants, steel mills, pharmaceutical producers, food manufacturers, chemical producers and other industrial companies often use baghouses to control emission of air pollutants.

Install Flow Measuring Venturi's or Flow Nozzles, and perform "Hot — K" calibration checks. We have done this for decades and I know of some flow nozzles installed in the mid 1980's, when I was with Flame, that still have the same reliable and accurate "K" factor. Not the least expensive but, they work, are accurate, and reliable.

The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transported from the mill outlet to the exhauster. From the exit of the exhauster, the coal and air mixture flows to the distributor box or riffle. From the riffle, the coal and air flow to the boiler burner panels.

pulverized coal at the mill outlet is 30%, the gas temperature required at the mill inlet is considered to be approximately 450°C. The evaporation of water in raw coal increases the vapor concentration in the gas at the mill outlet and consequently the O2 level of the primary gas in the burner is expected to be decreased to approximately 9%.

Coal mills are responsible for setting the dustair mixture up which is then burnt in the boiler. The research included the use of one of four mediumspeed ballandrace MKMtype coal mills. The raw coal comes down from the coal tank to the central chute pipe through the feeding screw and gets under the rolling balls being pulverized as a result.
