摘　　要：为了有效提高低浓度瓦斯发电机组的发电效率及发电量,对低浓度瓦斯发电机组的运行实况进行现场测量、记录,通过对检测数据进行通径分析,得到气源温度、环境温度及厂房温度与发电效率的相关性,通过理论分析计算了气源液态含水量及气源温度对发电效率的具体影响规律。结果表明:瓦斯气源品质对发电效率影响的最主要因素为瓦斯气源含水量,其次为瓦斯气源温度。针对关键影响因素提出一种余热降温及机械联合脱水系统,通过提升低浓度瓦斯进气品质的方式,提高低浓度瓦斯发电机组的发电效率。In order to improve the power generation efficiency and power generation capacity of low concentration gas generating sets effectively,field measurements and records of their operation were carried out,through path analysis of the data,the correlation between gas source temperature,environment temperature,plant temperature and power generation efficiency was obtained.The influence of the water content of gas source and the temperature of gas source on power generation efficiency was calculated through theoretical analysis.The results show that the main factor affecting the power generation efficiency is the water content of gas source,followed by the temperature of gas source.In view of the key influencing factors,a dehydration system combined with residual heat cooling and mechanical is proposed,which improves the efficiency of low concentration gas generating sets by improving the quality of low concentration gas intake.
