Abstract

The invention provides an exothermic catalytic combustion method for a pyrolysis gasification submelting furnace under pure oxygen conditions, which is characterized in that pure oxygen is directly introduced into the pyrolysis gasification submelting furnace for pyrolysis after the ignition. During the pyrolysis, catalysts, namely magnesium powder, aluminum powder or a mixture of the magnesium powder and the aluminum powder is added from the furnace bottom, and the adding amount of the catalysts is between 0.1 and 1.0 kg for each ton of treated substance. During the pyrolysis gasification, the pressure in the furnace is adjusted by adjusting the opening degree of a rectification mechanism to ensure that the pressure inside the pyrolysis furnace is stable. The method has the advantages of low cost, energy conservation, and environmental protection.

Description

technical field [0001] The invention relates to an exothermic catalytic combustion method under the condition of pure oxygen in a pyrolysis gasification sub-melting furnace, specifically relates to using pure oxygen for pyrolysis or ashing, exothermic by adding an exothermic catalyst, and the catalyst itself releases heat. The method for accelerating the exothermic reaction of the pyrolyzed matter while heating and accelerating the exothermic catalytic combustion belongs to the technical field of pyrolysis and gasification dual combustion control methods. Background technique [0002] Common pyrolysis gasifiers, incinerators, combustion furnaces such as double-furnace type, single-furnace type, or pyrolysis rotary kiln, etc., generally use oxygen-enriched, oxygen-deficient or low-oxygen The air combustion method under oxygen conditions, this process generally has requirements for compatibility and certain requirements for the calorific value of waste. Even so, in practical ...
