Measuring apparatus for coal combustion tendency

The utility model relates to a measuring device for coal spontaneous combustion tendency, which consists of a gas sample analysis and test system, a temperature-controlled box and an acquisition and control system which are arranged in an identical casing body; the gas sample analysis and test system consists of a carrier gas inlet pipeline entering the casing body, a chromatographic column connected with the carrier gas inlet pipeline, a thermal conductivity detector, a quantitative sampling pipe, and a plurality of micro magnet valves which control the ingress and egress of the gas flow of the carrier gas inlet pipeline; a coal sample reactor installed on a bracket is arranged in the temperature-controlled box, an gas inlet connected with a dry air inlet pipe is arranged at the bottom part of the coal sample reactor, and a gas outlet connected with the pipeline of the gas sample analysis and test system is arranged at the upper part; and the acquisition and control system consists of a temperature-controlled box temperature sensor arranged in the temperature-controlled box, a coal sample temperature sensor arranged on the coal sample reactor, a control module, an acquisition module, a display screen and a control panel. The measuring device is applicable to the measuring of the corresponding index parameters to the coal spontaneous combustion tendency oxidation kinetics measurement method, and has the advantages of compact structure, low cost, simple operation and accurate and reliable test result.
