Abstract

The invention relates to a system and a method for adjusting optimum control on combustion of a gas turbine, which aim at solving the current urgent problem of providing a method, with common suitability, for adjusting optimum control on combustion of a gas turbine. The method comprises the following steps of firstly, judging whether the gas turbine requires the combustion optimum control adjustment or not; after determining that the gas turbine requires the combustion optimum control adjustment, determining the effective running boundary range of combustion parameters of the gas turbine; then, collecting the parameter values of the gas turbine when entering the temperature-control full load state at different environment temperatures, comparing the effective running boundary ranges of thecombustion parameters of the gas turbine, analyzing the cause of combustion offset, determining the adjusting types of fuel adjusting values, and adjusting the equivalent ratio of fuel to air on linein real time; finally, increasing and decreasing the load of the gas turbine, adjusting and correcting the opening degree of each fuel adjusting valve on line, and repeating the steps until the gas turbine runs at the optimum state under the current environment condition. The method has the advantages that the optimum control on the combustion of various types of gas turbines can be adjusted, andthe application range is broad.

Description

technical field [0001] The invention relates to a gas turbine combustion optimization control adjustment system and an adjustment method, which belong to the key core technical field of gas turbines, and relate to combustion monitoring analysis and control adjustment of gas turbines. Background technique [0002] Gas turbines are currently recognized as environmentally friendly and efficient power generating units. There are mainly two types of gas turbines in my country, gas turbines and fuel oil turbines, of which gas turbines account for the vast majority, and pre-mixed dry low-nitrogen combustion methods are adopted. Each company has a wide variety of burners, including DLE, DLN1.0, DLN2.0, DLN2.0+, DLN2.6, DLN2.6+, etc., as well as HR3, ULN, F3, F4, etc. [0003] Since the optimization and control adjustment of gas turbine combustion involves the core control system and combustion system of the gas turbine, these technologies are in the hands of the suppliers. Domestic ...
