In the development of the Hydrogen-Oxygen combustor for 1700℃ Hydrogen-combustion turbines, it is important to measure gas temperature distribution at combustor outlet, where local temperatures are estimated over 1800℃, in order to evaluate the performance of combustors. Multi point gas temperature probes consisting of Pt/Rh 40%-Pt/Rh 20% thermocouples are developed to measure gas temperature distribution in the combustion tests of the Hydrogen-Oxygen combustors. Two types of probes, no-cooled and water-cooled, are designed and tested on the high pressure combustion tests. The test results demonstrate that the water-cooled type probes enable us to measure local gas temperatures up to 1850℃ in 2.5 MPa, 130 m/s steam flow, and are applicable to the combustion tests of the combustor.
