Study on small simulation device of coal spontaneous combustion process
Considering advantages and disadvantages of present ignition stations, the double nested spontaneous furnace with better thermal insulation performance was developed, and electrical sand bath was taken as thermal insulation and gas preheating device, also the temperature acquisition and temperature control device with higher accuracy was selected in order to solve the problems of heat dissipation and temperature control. The ignition furnace and sandbath attemperator of the device form the double insurance to protect the heat in the process of the coal spontaneous combustion reaction, and could guarantee the coal spontaneous combustion reaction process to be simulated scientifically and veritably. With this device, the coal sample of the SHIGANG COAL MINE was experimented to simulate the spontaneous combustion reaction process, proving that the device is feasible. The device can be used in the relevant experiments of coal spontaneous combustion.
