Problems solved by technology
[0003] The conventional underground coal gasification experimental furnace can only simply simulate the gas production characteristics of the solid coal combustion process and test the distribution laws of the temperature field, concentration field, and air flow field, but cannot simulate underground gasification under certain inclination angles and certain surrounding rock pressure conditions. Therefore, the relevant experimental data caused by the underground gasification process cannot be obtained, which cannot meet the needs of technology research and development, and makes the data and conclusions obtained from the experiment different from the underground gasification of coal seams under real geological conditions, reducing the experimental cost. Effectiveness and promotion of the development of underground coal gasification technology

The invention discloses a multifunctional underground coal gasification experimental furnace which comprises a furnace body and a base, and further comprises a bracket, a rotating shaft, a hydraulic supporting column, a compression plate and a fixing frame, wherein the bracket is fixed on the base; the rotating shaft is arranged on the furnace body and mounted on the bracket , and swings on the bracket to change the inclination angle of the furnace body; one end of the hydraulic supporting column is arranged on the base, the other end of the hydraulic supporting column is connected to the furnace body, and the hydraulic supporting column is used for controlling the inclination angle of the furnace body by changing the expansion length; the compression plate is arranged in the furnace body and used for applying a pressure into the furnace body; the fixing frame is fixed at the top of the furnace body, and a pressurizer is arranged on the fixing frame and is connected with the compression plate for applying a pressure to the compression plate. The multifunctional underground coal gasification experimental furnace disclosed by the invention can be used for simulating the underground gasification conditions under a certain inclination angle and certain surrounding rock pressure conditions, so as to obtain related experimental data in an underground gasification process.
Description
technical field [0001] The invention relates to the field of coal gasification experimental equipment, in particular to a multifunctional underground coal gasification experimental furnace. Background technique [0002] Underground coal gasification is a process in which coal in the ground is burned in a controlled manner, and combustible gas components are produced under thermal and physical and chemical effects, and transported to the ground; although this technology was proposed earlier, it is limited to various Aspects of factors, slow development, the defects of the experimental system is one of the reasons. [0003] The conventional underground coal gasification experimental furnace can only simply simulate the gas production characteristics of the solid coal combustion process and test the distribution laws of the temperature field, concentration field, and air flow field, but cannot simulate underground gasification under certain inclination angles and certain surrou...
