摘要
中油国际管道公司海外某天然气项目使用GE公司干式低排放LM2500+DLE燃气轮机驱动压缩机进行增输,燃气轮机自耗气占比达到管道年度输气量的1.3%及以上,自耗气已成为天然气管道运营最大成本。为契合公司持续推进降本增效的管理理念,从生产实践过程中发现,机组从怠速至额定负荷转速燃烧室5种燃烧模式的重叠区域B、B+C/2、BC、AB、ABC有明显的节能效果。从DLE机型的结构、工作原理,研究燃烧模式切换转速重叠区域的节能原理。通过1 a多的运行证明燃烧模式切换安全有效,可以用来指导燃气轮机操作人员将机组在高效节能区域运行,达到每台机每小时最高791 m^(3)/h天然气的节能效果。
The overseas natural gas project of International Pipeline Company is used GE's low-emission gas turbine LM 2500+DLE driven compressor to increase transmission.The self-consumption of gas turbine has been up to more than 1.3%of annual pipeline deliveries,and the self-consumption has become the largest cost of natural gas pipeline operation.In order to meet the company's management concept of continuously promoting cost reduction and efficiency,it is,from the process of production practice,found that there is obvious energy conservation effect in the overlapping area of five combustion modes in the combustion chamber from idle to full load speed:B,BC/2,BC,AB,ABC.From the structure and working principle of DLE model,the principle of energy conservation in the overlapping area of the combustion mode switching speed is studied.Through more than one year operation,it has proved that the method of combustion mode switching is safe and effective,which can be used to guide the gas turbine operators to operate the unit in a high-efficiency and energy conservation zone,reaching energy conservation of up to 567.7 kg of natural gas per hour per unit.
