【摘要】：惠州LNG电厂一期M701F3燃气轮机空气进气系统原设计为二级过滤,第一级过滤等级G4,第二级过滤等级F8。该过滤系统在运行中,过滤器过滤效率不高,压气机因通流积尘而效率下降明显。在空间布置合理的条件下,将原一级过滤器的等级改为为F5,二级过滤器的等级改为H11。压气机进气过滤器升级改造后,压气机的进气阻力、压气机特性、燃气轮机及联合循环运行特性将发生变化。为定性定量评估改造前后机组的运行性能,并判明该高效过滤器的推广应用价值,开展以下研究内容：(1)以M701F3燃气轮机空气进气过滤系统为研究对象,对过滤器更换前后的特性进行研究对比；(2)通过燃气轮机的建模与仿真,研究压气机进气滤网压差变化对燃气轮机及其联合循环机组性能的影响；(3)结合燃气轮机的结构和原理,对高效过滤器的节能和经济效益进行评估。通过对系统数据的采集、理论推导和大量分析对比计算,初步得出压气机进气滤网压差变化对燃气轮机机组性能的影响规律,在此基础上提出了进气滤网的运行优化策略并估算了由此产生的经济效益。
[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.
