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.

When glass fiber fabrics were introduced, a gentler means of cleaning the bags, which may be a foot in diameter and 30 feet in length, was needed to prevent premature degradation. Reverseair cleaning was developed as a less intensive way to impart energy to the bags. In reverseair cleaning, gas flow to the bags is stopped in the compartment

Experimental data demonstrate that the developed system is effective and reliable for the online continuous measurement of PF mass flow distribution between the primary air pipes of the same mill. Online measurement of pulverized fuel (PF) distribution between primary air pipes on a coalfired power plant is of great importance to achieve balanced fuel supply to the boiler for increased ...

A process flow diagram for a typical coal cleaning plant is presented in Figure In the initial preparation phase of coal cleaning, the raw coal is unloaded, stored, conveyed, crushed, and classified by screening into coarse and fine coal fractions. The size fractions are then conveyed to their respective cleaning processes. Fine coal ...

Coal left in the ground can catch fire, and mine fires are difficult to control, with some burning for decades or even centuries, creating a major source of air pollution. The use of explosives, such as in mountaintop removal, releases carbon monoxide (CO). Dust and coal particles stirred up during the mining process, as well as soot released ...

Activated carbon. Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, lowvolume pores that increase the surface area available for adsorption (which is not the same as absorption) or chemical reactions. Activation is analogous to making popcorn from ...

Reverse air (R/A) baghouses use continuous streams of low pressure air to remove collected solids. Bags are cleaned by backwashing (reversing the air flow) within a chamber after shutting off the dirty gas flow and isolating the compartment. The recommended air to cloth ratio for these baghouses is between :1 and :1. Advantages
