METHOD OF DESTRUCTION OF CARBON AND NITROGEN-CONTAINING RAW MATERIAL AND DEVICE FOR ITS REALISATION Russian patent published in 2014 - IPC F23G5/27 C10J3/02 F23B90/00 F23B30/06 

FIELD: chemistry.

SUBSTANCE: method of destruction of a carbon and nitrogen- containing raw material includes supply of the carbon and nitrogen-containing raw material into a cylindrical case, its heating, creation of depression inside an internal case cavity, output of gas and discharge of a sol residue. The internal case cavity is preliminarily heated before supply of the raw material into a channel of loading, the raw material, supplied constantly from the channel of is loading, is moved by means of an auger and successively directed into a chamber of initial decomposition, heating to a temperature of 120-340°C under pressure of 600-500 KPa, formed moisture and initial pyrolysis gas are output though a gas-output net into a chamber of afterburning, supplying in it oxygen in a composition of air in a dosed way until oxides CO, NO are obtained, then the raw material is subjected to destruction at first in the first zone at a temperature of 340-1000°C and pressure 600-700 KPa, and then in the second zone at a temperature of 1700°C and pressure 900-700 KPa. Depression in the zones is regulated by changing depression in tubes of a depression contour, which belong to the respective zone, oxygen in the composition of air in the case shaft is supplied through a window of a sol canal.

EFFECT: invention makes it possible to increase a degree of the raw material destruction.
