输气管道压气站余热的利用

Waste heat utilization from compressor station of gas pipeline

  • 摘要: 燃驱压气站的余热利用有热、电和机械3种途径。分析比较了压气站中应用相对成熟或应用潜力较大的余热利用有方案:燃气轮机余热锅炉回收、燃气轮机回热循环、蒸汽郎肯循环、有机郎肯循环、燃气轮机进气制冷。各个方案均有较多应用业绩,但亦有其局限性,有机郎肯循环选用有机介质,技术较成熟,应用前景前较好,溴化锂吸收式制冷技术利用燃机废热对燃机进行进气制冷,以提高燃气效率,目前仅在燃机电站应用,亦可应用于压气站。选择余热利用方案时,应结合压气站现有条件、机组性能以及运行模式等因素进行综合评估。

     

    Abstract: Waste heat utilization from compressor stations of gas pipeline is an important means to improve pipeline operating level and energy saving and efficiency increase. In fuel-driven compressor station, the waste heat utilization can be achieved based on heat, electricity and machinery. This paper analyzes the utilization plans of waste heat in compressor station which are relatively mature or have great application potential, such as waste heat recovery boilers of gas turbine, gas turbine regenerative cycle, steam Rankine cycle, organic Rankine cycle, gas turbine inlet air cooling. Each plan has many application cases, but also has its limitations. Organic Rankine cycle is more mature and uses organic media, with better application prospects. Lithium bromide absorption refrigeration technology can use waste heat from gas turbine for refrigeration to improve the gas efficiency, and now is only applied in gas turbine power plants, but it can also be used in gas compressor stations. It is pointed out that when selecting waste heat recovery plans, a comprehensive assessment combined with existing conditions of gas compressor stations, unit performance, and operating mode and other factors should be carried out, this has certain significance for next stage reconstruction and construction of pipeline using waste heat in gas compression station.
