·Controlling dust generation and keeping it below permissible limits to meet federal dust standards at the working face of a room and pillar coal mine is a challenge for a mine operator With the recent changes in federal dust regulations requiring lower worker exposure maintaining compliance has become increasingly difficult The current most effective practice
· Wet Scrubbers Wet scrubbers are the most widely used FGD technology for SO 2 control throughout the world Calcium sodium based sorbents have been used in a slurry mixture which is injected into a specially designed vessel to react with the SO 2 in the flue gas Commercial wet scrubbing systems are available in many variations and proprietary designs
As the coal dust present in the air poses multiple threats and is disruptive to the working process multiple ways of controlling and reducing coal dust presence have been developed one of which is coal dust wet air scrubbing The most effective way to reduce the risks that come with coal dust present in the air is to significantly reduce the

·This novel scrubber has been used as dust collecting wet scrubber in presence of other gaseous and vapor pollutants This paper reports on the detailed experimental investigations carried out on the scrubbing of fly ash in this novel wet scrubber using water as the scrubbing medium fired thermal power plant using coal with 35% ash content
As indicated in Figure 3 1 wet scrubbing systems in coal fired electric generating plants may be used to collect particulate matter and/or to scrub S02 from the flue gas the flyash emission quantity will be approximately proportional to the ash content of the coal Inlet dust loadings in utility flue gas may vary from 2 to 12 gr/dscf but
·Coal gasification and coal burning processes release different air pollutants including fly ash and many acid gases into the environment To overcome this problem wet scrubbing techniques are important by which very fine particulates can be removed effectively The experiments of fly ash scrubbing were conducted in three stage dual flow
·The term Flue Gas Desulphurisation FGD system has traditionally referred to wet scrubbers that remove SO 2 emissions from large electric utility boilers The FGD systems emerged in the industrial field of the coal fired power plants and on some industrial processes in the early 1970s in United States US and Japan and expanded rapidly in the 1980s [1] in
