[Abstract]:The first stage M701F3 gas turbine air intake system of Huizhou LNG Power Plant was originally designed as two stage filtration, the first stage was G4, the second stage was F8. The filter efficiency was not high in the operation of the system. Under the condition of reasonable space arrangement, the grade of the original primary filter is changed to F5, and the grade of the secondary filter is changed to H11.After the compressor intake filter is upgraded, the intake resistance of the compressor is improved. The performance of compressor, gas turbine and combined cycle will be changed. Carry out the following research contents: 1) take the M701F3 gas turbine air intake filtration system as the research object, compare and contrast the characteristics of the filter before and after the change of the filter 2) through the modeling and simulation of the gas turbine, This paper studies the influence of the pressure difference of compressor inlet filter on the performance of gas turbine and its combined cycle unit. (3) combined with the structure and principle of gas turbine, the energy saving and economic benefit of high efficiency filter are evaluated. Based on the theoretical derivation and a large number of analysis and comparison calculations, the influence of pressure difference on the performance of gas turbine units is preliminarily obtained. On the basis of this, the operation optimization strategy of intake air filter is put forward and the economic benefit is estimated.
