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.

Operation. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles. The primary air flow to the furnace is fed through the mill, with the purpose of heating and lift the coal particles out ...

Introduction. Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coalfired thermal power plants, the raw coal is first pulverized to the shape of flour before it is forcefed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separated ...
