Bags are most common type of fabric filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. Fabric filters are frequently referred to as baghouses because the fabric is usually configured in cylindrical bags. Bags may be 6 .
Fabric filters, which generally operate in the temperature range 120180°C, have been more widely used since the 1970s, especially at industrial scale. The choice between ESP and fabric filtration generally depends on coal type, plant size and boiler type and configuration.
Anthracite media is a select coal that is mined and processed for water treatment applications. Crushed anthracite makes an excellent medium density filtration media that effectively filters sediment and turbidity and is commonly used in multimedia filters.

CEI Anthracite manufactures high quality, dry and low uniformity coefficient anthracite filter media. CEI Anthracite''s < uniformity coefficient can provide many benefits in granular bed filters, including: Increased plant capacity by the use of higher filtration rates; Lower backwash rates in dual and trimedia filters
An electrostatic precipitator (ESP) is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.. In contrast to wet scrubbers, which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and ...

May 04, 2011· There are two principal systems that are used for removing particulates from the flue gas of a coalfired power station, electrostatic precipitators (ESPs) and fabric (baghouse) filters. Cyclones can also be used to capture particulate material but they tend to be used on smaller plants.
Evaluating Mercury Control Technologies for Coal Power Plants Controls designed to remove other pollutants can remove a substantial amount of mercury under certain conditions.
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.
(4) the service life of the filter bag. The life of the filter bag is connected with material, the flue gas temperature, composition, acid dew point, dust properties related to, such factors, but also by filtering wind speed, entrance dust concentration, the clear dust frequency and the influence of the management and maintenance.
