The basic principle of the instrument is to determine the composition of the gas according to the thermal conductivity of the gas, that is, to determine the content of a gas in the mixed gas by measuring the thermal conductivity of the mixed gas [1] , and the hydrogen thermal conductivity is the highest in the mixed gas. Therefore, when the background gas (such as N2, etc.) or other components in the mixed gas is kept substantially constant, the thermal conductivity of the mixed gas depends substantially on the amount of hydrogen, so that the contained content can be measured according to the thermal conductivity in the mixed gas. How much is hydrogen. The TFS-H2 thermal conductivity hydrogen analyzer can be used to continuously and automatically analyze the percent concentration of hydrogen in various mixed gases. It has the characteristics of high accuracy, simple structure, small maintenance and long service life. It is mainly used in non-explosion-proof places such as thermal power plants, hydrogen plants in chemical fertilizer plants, and also in scientific research institutions and laboratories. 1. Power plant: The purity of the hydrogen used for cooling in the generator hydrogen cooling system is analyzed and the percentage of hydrogen in the environment is measured. 2. Fertilizer plant: The percentage of hydrogen in fresh gas and circulating gas in the process of nitrogen synthesis ammonia. 3. Steel plant: analysis of net gas after blast furnace gas removal
