Simulation Experimental Test System for Coal Spontaneous Combustion

Coal spontaneous combustion test conditions under the condition of actual approximate adiabatic and additional heat source are simulated, and coal spontaneous combustion simulation test system is established. The system is mainly composed by air supply system, furnace body, coal temperature detection, temperature control device and gas analysis system, which can directly access coal body neice point temperature, gas component concentration distribution. With coal spontaneous combustion test conditions, it not only provides experimental conditions for the determination of coal spontaneous combustion stage, but also can simulated medium-sized coal spontaneous combustion process under laboratory conditions, which provides technical support for testing the reliability of wireless temperature sensor network node device.
