Performance detection and analysis method for gas turbine air intake filter

Abstract

The invention relates to a performance detection and analysis method for a gas turbine air intake filter. The method comprises the steps of S1 data collection and S2 intake air filter resistance correcting. According to the step S1, the air pressure of each air intake filter at an air intake filter air inlet in a number of periods of time are simultaneously measured to acquire a first air pressure value; the air pressure of a filter air outlet is simultaneously measured to acquire a second air pressure value; and the air flow of the filter air outlet is simultaneously measured to acquire the air flow value at each time point in different periods of time. According to the step S2, the resistance of the air intake filter is corrected based on the measured first air pressure value, the second air pressure value and the air flow value to acquire the corrected resistance of the filter. The method can be used to effectively select a required gas turbine air intake filter.

Description

technical field [0001] The invention relates to the technical field of gas turbine intake filter detection, in particular to a performance detection and analysis method of gas turbine intake filter. Background technique [0002] A gas turbine is a rotary power machine that uses continuously flowing gas as a working medium to convert thermal energy into mechanical energy. Because it uses air as the working medium, the quality and purity of the inlet air of the gas turbine are the prerequisites for effectively operating the gas turbine and improving the performance and reliability of the gas turbine. Before the air enters the gas turbine, the air entering the compressor needs to be treated to filter out impurities. As an essential guarantee system, the gas turbine air intake system is generally arranged at the front of the gas turbine, and mainly consists of a rain cover, an air intake filter system, an air intake cooling or heating anti-icing component, a muffler, measuring ...

AI Technical Summary

Problems solved by technology

At the same time, the main engine manufacturers have insufficient understanding of the regional differences in China, and have not designed the gas turbine intake system in a targeted manner. As a result, the gas turbine intake system in my country generally has the problem of poor environmental adaptability, and excessive gas turbine intake pressure loss often occurs. The problem of abnormal shutdown of the unit

In addition, when gas turbine power plants select air intake filters, the existing detection methods are not enough to accurately evaluate the adaptability of the filter to the power plant environment, so the operating time of the filter after replacement often does not reach the designed service life

The emergence of the above problems has greatly affected the operation safety and economy of gas turbine power plants, and brought great troubles to the operation of power plants
