DEVICE AND THE METHOD OF CONTROL OVER NITROGEN DIOXIDE EJECTIONS FROM THE BOILERS BURNING THE CARBONIC FUELS WITHOUT USAGE OF THE EXTERNAL REACTANT Russian patent published in 2007 - IPC B01D53/86 F23J15/02 F23C7/00 F23N3/00 

FIELD: environmental protection; devices and the methods of control over NO_x contents in the flue gases ejected from the boilers burning the carbonic fuels.

SUBSTANCE: the invention is pertaining to the device and the method of control over NO_x contents in the flue gases ejected from the boilers burning the carbonic fuels. The method includes injection of the carbonic fuel and the air into the burning zone of the furnace of the boiler for incineration of the carbonic fuel in the conditions of oxidization and production of the flue gas including_{NOx and CO, and directing the flue gas from the furnace into the section of the catalyst in the channel of the flue gas for restoration of NOx and CO and conversion of the NOx and CO without injection of the external reactant intoN2 and CO2 by usage of CO in the capacity ofthe deoxidizer for NOx on the catalyst in the catalytic section. The technical result of the invention is development of the device and the method for control over the NOx ejections from the boilers burning the carbonic fuels, which are maintaining the high thermal efficiency of the boilers without the increase of ejections of other pollutions and which do not use any external reactant.}

EFFECT: the invention ensures development of the device and the method for control over the nitrogen dioxide ejections from the boilers burning the carbonic fuels, which are maintaining the high thermal efficiency of the boilers without the increase of the ejections of other pollutions and which do not use any external reactant.
