METHOD AND SYSTEM FOR REAL-TIME CONTROL OF BURNING WITHOUT WATER INJECTION WITH LOW EMISSION OF NITRIC OXIDES AND DIFFUSION COMBUSTION Russian patent published in 2017 - IPC G05B23/02 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to the method of controlling and diagnosing of malfunctions in the operation of gas turbine. To implement the method, a computer device is used togethwer with an interface device and the device with previously stored thereon sets of rules relating the real time output and input data of the gas turbine operation, in this case the input data are related to the temperature variation of the exhaust gases flow, state of the gas turbine flame detectors, turbine switching into another operating mode, the pressure drop in the fuel gas line is determined and compared with the threshold values, recommendations are given to the gas turbine operator to switch it to another mode provided the pressure diferential meets the specified range of threshold values. Additionally, the faulty combustion chamber is identified by determining the twist angle of the exhaust gases flow by determining the temperature variation from the temperature sensors and compliance with its temperature variation threshold for the specific combustion mode.

EFFECT: invention expands the set of methods of control and diagnostics of malfuncations in the gas turbine operation with the help of computer, interface and memory devices, thereby providing timely provision of information about gas turbine malfuncations to prevent accidental shutdowns.
