FIELD: by-product-coking industry; methods of purification of waste gases of the fuel incineration furnaces.
SUBSTANCE: the invention is pertaining to the field of by-product-coking industry, in particular, to the method of purification of waste gases of the fuel incineration furnaces. The method is defined by the fact, that using a part of the purified waste gases they form a backflow used for creation of a counterflow to the main stream of the waste gases and formation of a total flow fed to the purification. At that the speed of the backflow is kept within the limits of 0.1-1.0 m\s, and temperature of the total flow is kept by 2-30°C below the temperature of the main stream of the waste gases. The invention allows to raise efficiency of the smoke purification due to regulation of parameters of the hydraulic mode of the offered method.
EFFECT: the invention ensures a raise of efficiency of the smoke purification.
