摘　　要：根据农村户用沼气池的系统特征和沼气的燃烧特性,设计研制了功率分别为700,1800,3800,4800 W等系列的户用沼气发电装置.介绍了户用沼气发电装置中发动机的混合器、燃烧室、压缩比、火花塞等关键部件的设计.针对1800 W的发电装置进行试验测试,结果表明,该装置沼气消耗率为0.50 m3·kW^-1·h^-1,启动气压范围在2-12 kPa之间,工作气压范围在0.5-10 kPa之间,输出电压220 V.该发电装置运行稳定.According to the system characteristic of the household methane digesters and the combustion characteristic of methane, a series of household methane generators were designed and manufactured,the power respectively being 700,1 800,3 800, 4 800 W. This paper mainly introduced the key component design and the research of the household methane engine, such as methane-air mixer, combustion chamber,compression ratio,igniter plug. The test result of 1 800 W generator shows its output of voltage is 220 V, rate of methane consume is 0.50 m^3 · kW^ - 1 · h^- 1, range of startup air pressure is 2 - 12 kPa and running air pressure is 0.5 - 10 kPa. The equipment runs stably.
