The paper proposed a design scheme of oxidation kinetics testing equipment for coal spontaneous combustion tendency on the basis of oxidation kinetics testing method of coal spontaneous combustion tendency, and introduced working principle of the equipment, selection of gas source, design of supply equipment of standard gas, building of coal sample response, type selection of gas analyzing instrument and design of control and displaying board. The experiment showed that the equipment can realize functions of automatic sampling, automatic analysis and on-line collection, and the experimental result is repeatable excellently, which verifies stability of the equipment.
