Description

technical field [0001] The invention relates to a coal powder pyrolysis combustion reactor, in particular to a reactor for simulating boiler coal powder suspension pyrolysis combustion. It belongs to the technical field of thermal power engineering. Background technique [0002] Pulverized coal boiler is a boiler equipment that uses pulverized coal as fuel. It has the characteristics of complete combustion reaction, wide adaptability of coal types, and wide application. After the raw coal is ground by a coal mill, it becomes coal powder particles, and the coal powder particles are sent to the furnace for pyrolysis and combustion under the blowing of the primary wind. The chemical process of coal powder pyrolysis combustion is realized in a suspended state. . Most of the reactors in China that study the pyrolysis and combustion reaction process of pulverized coal include thermogravimetric analyzers, reactors, fixed beds, etc., all of which pile up pulverized coal particles...
