A working model of a thermochemical gas analyzer for continuous detection of oxygen in gaseous mixtures containing up to 10 O2 has been constructed and tested under laboratory conditions. The action of the gas analyzer is based on using the relationship of the emf of a platinum and iridium platinum thermocouple, on which flameless hydrogen combustion occurs at a temperature in the gaseous medium of 250-300 degrees due to the oxygen in the gas to be analyzed. The research data may be used for developing an automatic gas analyzer for continuous detection of oxygen directly in a stream of hot gas.
