Abstract

The invention discloses a method for determining the optimum off-line water washing cycle of a gas turbine, comprising: collecting the maximum load P of the gas turbine after water washing 1 and the data of running time t; the maximum load P 1 Corrected to the ISO maximum load P; fitting the functional relationship between the ISO maximum load P and the running time t; according to the functional relationship, the effective power generation W in the 2T period of the adjacent two washing periods is calculated; according to the effective power generation W calculates the average load during the 2T period ; Find the average load The optimal off-line water washing cycle T value when is the maximum value. The invention solves the problems of unreasonable water washing time arrangement of the gas turbine, resulting in high washing cost, low unit efficiency, and affecting economic benefits, greatly reduces the washing cost, and maximizes the washing benefit.

Description

technical field [0001] The invention relates to the cleaning of gas turbines, in particular to a method for determining the optimum off-line water washing period of the gas turbines. Background technique [0002] The gas turbine directly uses air as the working medium. Although a filter device is installed at the inlet of the gas turbine, it is still inevitable that the impurities in the air enter the compressor and adhere to the blades of the compressor, resulting in a decrease in the flow area of ​​the compressor and a decrease in the efficiency of the gas turbine. Seriously Sometimes even affect the safe operation of the gas turbine. In order to ensure the safe and efficient operation of the gas turbine, it is necessary to regularly shut down and wash the gas turbine to restore the efficiency and output of the gas turbine; however, a large amount of factory power is consumed during the washing process, and the cost of using a special cleaning agent for washing the gas tur...
