【摘要】：惠州LNG電廠一期M701F3燃氣輪機空氣進氣系統(tǒng)原設計為二級過濾,第一級過濾等級G4,第二級過濾等級F8。該過濾系統(tǒng)在運行中,過濾器過濾效率不高,壓氣機因通流積塵而效率下降明顯。在空間布置合理的條件下,將原一級過濾器的等級改為為F5,二級過濾器的等級改為H11。壓氣機進氣過濾器升級改造后,壓氣機的進氣阻力、壓氣機特性、燃氣輪機及聯(lián)合循環(huán)運行特性將發(fā)生變化。為定性定量評估改造前后機組的運行性能,并判明該高效過濾器的推廣應用價值,開展以下研究內(nèi)容：(1)以M701F3燃氣輪機空氣進氣過濾系統(tǒng)為研究對象,對過濾器更換前后的特性進行研究對比；(2)通過燃氣輪機的建模與仿真,研究壓氣機進氣濾網(wǎng)壓差變化對燃氣輪機及其聯(lián)合循環(huán)機組性能的影響；(3)結(jié)合燃氣輪機的結(jié)構(gòu)和原理,對高效過濾器的節(jié)能和經(jīng)濟效益進行評估。通過對系統(tǒng)數(shù)據(jù)的采集、理論推導和大量分析對比計算,初步得出壓氣機進氣濾網(wǎng)壓差變化對燃氣輪機機組性能的影響規(guī)律,在此基礎上提出了進氣濾網(wǎng)的運行優(yōu)化策略并估算了由此產(chǎn)生的經(jīng)濟效益。
[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.
