METHOD OF RECYCLING FLUE GASES DURING COMBUSTION OF WASTES IN INCINERATOR PLANT IN ORDER TO REDUCE HARMFUL EMISSIONS INTO ENVIRONMENT Russian patent published in 2024 - IPC B01D53/56 

FIELD: fuel combustion devices.

SUBSTANCE: invention relates to a method for recycling flue gases when burning wastes in an incinerator plant. Technical result is achieved by the method of flue gas recirculation during combustion of wastes in an incinerator installation, which includes the flue gases extraction from the flue and their direction through the bypass pipeline into the ambient air duct. Further, in the blowing fan, flue gases are mixed with external air to obtain a mixture of external air and flue gases in a proportion that reduces the percentage of oxygen in the external air to a level, at which at the outlet of the chimney the content of oxygen in the flue gases is less than 1 % with the absence of carbon monoxide according to the readings of the gas analyser. After that produced mixture is heated in recuperator and supplied to combustion chamber and afterburning chamber of flue gases through air duct.

EFFECT: reducing emissions of nitrogen oxides and carbon dioxide into the environment.
