四川省兴办沼气的时间较早,数量较大,有“沼气之乡”之称。全省有家用小沼气池400多万个。近几年来在家用小沼气池的基础上,又建立了小型沼气动力站和小型沼气发电站800多处,装机容量达4500多千瓦。这些给农村带来了光明,使农民获得了实惠。成都南郊区光荣大队一生产队,1980年初兴建了一个600m~3的沼气池,配备两台内燃机,采用油气混烧(柴油30%,沼气70%)。一台12马力柴油机专作打米、磨面用;一台2100型22马力柴油机配 T_2S 型12千瓦三相同步发电机作照明发电用。白天打米磨面,晚上发电照明。所产沼气可供5小时/每天使用。由于沼气燃料成本低,生产队每年可从该沼气站获利1000元左右。重庆巴县石庙公社,地处海拨1060米的高山上,当地农民从未见过电灯,在1979和1980年两年中,建成三十三座小沼气电站,装机容量达170多千瓦,使40%的农户用上了电灯,不少生产队 Sichuan Province to run biogas earlier, a large number, a “hometown of biogas,” said. There are more than 4 million domestic digesters in the province. In recent years, based on the small household biogas digesters, more than 800 small-scale biogas power stations and small-scale biogas power plants have been set up with an installed capacity of more than 4,500 kilowatts. These have brought light to the countryside and made the farmers more profitable. A production team of Glory Brigade in the southern outskirts of Chengdu built a 600m ~ 3 biogas digester at the beginning of 1980, equipped with two internal combustion engines and mixed with oil and gas (30% of diesel and 70% of biogas). A 12 horsepower diesel engine specifically for playing rice, grinding noodles; a 2100 hp 22 hp diesel engine with T_2S 12 kW three-phase synchronous generator for lighting power generation. Milling the rice during the day, night power lighting. Biogas produced for 5 hours / daily use. Due to the low cost of biogas fuel, the production team can make a profit of 1,000 yuan a year from the biogas station. Chongqing Baxian Shi Miao commune, located 1060 meters above sea level on the mountain, the local peasants have never seen electric lights in 1979 and 1980 two years to build 33 small biogas plants installed capacity of 170 kilowatts, So that 40% of farmers use the lights, many production team
