摘　　要：根据沁水盆地煤层气开采情况设计出使用回热型燃气轮机循环、太阳能辅助燃气-蒸汽联合循环、燃气-卡琳娜联合循环来驱动压缩机作功,用以给工煤层气开采增压的工艺方案。将燃气轮机余热利用技术应用到输气管道增压驱动中。基于总能系统理论和能量梯级利用原则,通过ASPEN PLUS软件对3种增压系统建模,并对各个系统进行热力性能分析及节能潜力分析。分析表明:3种方案的发电效率分别为60.42%、66.51%和65.73%,年节省成本分别为239.83、272.54和268.58万元,静态投资回收期分别为4.19、4.29和4.80 a,CO2减排量分别为3 806.06、4 462和4 382.60 t/a,具有较好的节能潜力。Under the coal bed gas production conditions in Qin-shui basin,three coal bed gas supercharging process system versions for recuperative type gas turbine cycle,solar energy aided gas-steam combined cycle,gas-Kalina combined cycle driving system were designed and the gas turbine waste heat utilization technologies were applied in the supercharging and driving of gas in gas transmission pipelines. Based on the total energy system theory and energy staged utilization principles,a model for the three supercharging systems was established by using the software Aspen Plus and an analysis was also performed of the thermal performance and energy saving potential of various systems. The analytic results show that the power generation efficiencies of the three versions are 60. 42%,66. 51% and 65. 73%respectively,the costs saved each year are RMB 2. 3983 million yuan,RMB 2. 7254 million yuan and 2. 6858 million yuan respectively,the static investment payback periods are 4. 19 years,4. 29 years and 4. 80 years respectively and the carbon dioxide emissions reduced are 3806. 06 t / a,4462 t / a and 4382. 60 t / a,respectively thus enjoying a relatively good energy saving potential.
