Methanation reaction principle of CO and CO2, under certain temperature and methanation catalyst and reacts with H2, CH4 production and water vapor, through the rear cooling, water vapor condensation separation, finally only containing CH4 impurity hydrogen qualified. The methanation reaction is the volume is reduced, the strong heat release process. According to the characteristics of the process, our company specializes in the development of a multi point pair, suitable for methanation reactor temperature.
The measured medium of radiation-protective air-suction thermocouple is flue gas, of which the highest temperature is 1100 ° C. Its functions are mainly radiation and sir suction. The radiation principle is similar to radiation-protective thermocouple. The injected medium, such as compressed air or high-pressure steam, is sprayed by the injector, in the injector nozzle the minus pressure and suction force are formed so that the measured medium flows through the thermocouple hot junction in the high velocity, which will increase the convectional heat transfer, and in turn keep the measurement more accurate.
