Abstract: The basic function of the gas turbine exhaust temperature dispersity monitor system was introduced. Taking the DLN2.0+ combustion chamber as example, the importance of the exhaust temperature dispersity monitoring and protection function for the gas turbine was explained. The formation mechanism of bulging and cracking of combustor inner liner and his influence on gas turbine exhaust temperature dispersity was analyzed. Some relevant measures were proposed to prevent the components in heat passage from hurt due to combustion deterioration.

Key words: gas turbine, dispersity of exhaust temperature, combustor inner liner, bulging, temperature field, combustion mode
