The flue gases coming out of the boiler contains dust particle’s embedded in it.The pollution control board of a particular area has limitation on the concentration of dust particles in the gases which are to be release from boiler to the atmosphere.n order to minimize this dust content from the flue gases dust collector system is being used.The main structure due to which the separation takes place is a pipe in pipe construction.The lower side of the outer pipe is tapered downwards.Two duct openings are placed on the flue gas inlet and outlet sides with flanges.
