| Abstract:Gas analysis method and thermocouple method were taken to measure outlet temperature field to provide the technical
support for the optimization of outlet temperature distribution of high temperature rise full annular combustor. Two five-hole samplers were
fixed on a traverse gear, swinging 180毅and collecting six hundred gas samples from combustor outlet, the gas temperature were calculated
by measuring carbon dioxide and carbon monoxide. The combustor outlet temperature distribution measured by gas analysis method and
thermocouple method are consistent basically at fuel/air ratio 0.03. The hot-spot temperature measured by gas analysis method was 2285 K
at fuel/air ratio 0.037. The error analysis show that the primary factors which affect oreatly gas analysis measuring temperature are carbon
dioxide and fuel calorific value. The overall error of greatly gas analysis test system is better than 1%. The result show that gas analysis
method is a reliable high temperature measurement technique with high precision. |
