摘　　要：次高压、中压燃气在供给用户之前,需要经过调压装置调压,调压过程压力能损失较大,利用燃气调压过程压差发电将会有效回收这部分压力能损失。燃气压力能进行了热力学分析,燃气比由比温度和比压力组成,比压力远大于比温度。利用压缩空气模拟中压燃气,搭建了中压管道压差发电实验系统,实验研究了流量、压力比对压差发电的影响,通过实验数据拟合得到了发电功率(P)与流量(Q)、压力比(n)之间的关系式为P=16.10Qlnn。Experimental study of generation using gas with intermediate pressure,medium pressure natural gas with intermediate pressure and medium pressure should be regulated before transmission and distribution.Regulating process may cause waste of pressure power, which needs to be used by power generation. Thermodynamic analysis was conducted. Compressed air,employed to simulate epressurized gas,was used in medium-pressure power generation system. The influence of flow rate,pressure on power generation was investigated. The function of generation power,flow rate and pressure ratio was summarized as P = 16. 10 Qlnn.
