摘　　要：介绍了有机朗肯循环发电机组的基本原理和螺杆膨胀发电机组的基本结构;简述了利用低压蒸汽冷凝液余热的经济效益和节能减排效益。研究结果表明:采用螺杆膨胀发电机组回收低温余热,不仅可以提高项目能效0.2%,还可减少排放CO225 532 t/a,节约标准煤9 820 t/a。Author has introduced the basic principle of Organic Rankine Cycle Generator Units and the basic structure of screw expansion generator u-nits; has briefly described the economic benefit and energy conservation and emission reduction benefit using the waste heat of low pressure steam conden-sate.Result indicates that using screw expansion generator units to recover the waste heat of low temperature not only can increase the energy efficience of project by 0.2%, but also can reduce the emission of CO2 by 25 532 t/a and save standard coal by 9 820 t/a.

关 键 词：低压蒸汽冷凝液 余热 有机朗肯循环 螺杆膨胀发电机组 节能
