DIAGNOSIS PROCEDURE FOR CONDITION OF COMBUSTION CHAMBER OF GAS-TURBINE INSTALLATIONS Russian patent published in 2010 - IPC G01M15/14 

FIELD: power industry.

SUBSTANCE: there are measured parametres in exhaust column. Results of measurements are processed by means of methods of mathematic statistics. Condition of the combustion chamber is evaluated on base of deviation of the results from reference values. Temperature of gases and concentration of combustion products in them are taken as gases parametres in the exhaust column. Also standard deviations of gases temperature and concentrations of combustion products are determined at processing the measurement results. As a reference value for comparison there is chosen the reference value of standard deviations of gases temperature and concentration of combustion products determined on results of measurements of these values for each type of engines from the beginning of its operation to the end. Concentrations of carbon and nitrogen oxides are determined by 5 successive measurements during 20 minutes at evaluating combustion products concentrations.

EFFECT: simple and accurate diagnostics of condition of gas-turbine installation combustion chamber under set mode without additional equipment.
