Abstract
Surface temperature measurement of a hot surface is necessary in order to determine its thermal life. The combustors used in gas turbine systems may be subject to high thermal load due to continuous combustion. In order to analyse the surface temperature distribution of combustor, temperature-sensing instruments are necessary. Temperature-indicating paint is a kind of coating to measure the temperature distribution through its colour change. Temperature-indicating paint is considered to be one of the most efficient ways for temperature measurement. The analysis of this paint can be done through the observation of irreversible colour change with temperature. This work deals with the fabrication of gas turbine combustor, investigates the thermal distribution and finds the hot spots of the combustor using temperature-indicating paint.
