Biogas Power Generation Project
沼氣發電工程是集環保和節能于一體的能源綜合利用工程。它是利用工業、農業或城鎮生活中的大量有機廢棄物（例如禽畜養殖場糞污，酒廠、食品廠等各種加工廠的有機廢棄物，餐廚垃圾、城市垃圾和污水等），經厭氧發酵處理產生的沼氣，驅動沼氣發電機組發電上國家電網或工廠自用，也可用于溫室種植供熱。另外沼氣也可供工業與民用燃氣，沼液作為液態有機肥，沼渣加工成固態有機肥，可以為農作物種植提供肥料。
Biogas power generation system is an energy saving and environmental friendly system. It’s to use industrial waste (organic waste in winery,food factory and etc.),agricultural waste(farm animal waste) or municipal domestic waste(restaurant waste,kitchen waste,urban waste and etc.) to produce biogas by anaerobic fermentation. Power generated by biogas engine may be connected to grid or self consumed. Waste heat from biogas engine may be used in production of biogas(anaerobic fermentation),greenhouse heating, industrial heat supply or civil heat supply. Besides, biogas may also be used as industrial fuel gas or civil fuel gas. Biogas liquid is used as liquid organic fertilizer. Biogas residue may be processed to solid organic fertilizer used in agriculture.
沼氣發電技術本身提供的是清潔能源，不僅解決了沼氣工程中的環境問題、消耗了大量廢棄物、保護了環境、減少了溫室氣體的排放，而且變廢為寶，產生了大量的熱能和電能，符合能源再循環利用的環保理念，同時也帶來巨大的經濟效益。沼氣發電具有創效、節能、安全和環保等特點，是一種分布廣泛且廉價額分布式能源。
沼氣發電在發達國家已受到廣泛重視和積極推廣。生物質能發電并網在西歐一些國家占能源總量的10%左右。
Organic wastes are converted to heat and electricity in the biogas power generating system. Biogas power generating system is a clean,efficient,economic and safe power generating system. It’s valued and widely spread in developed countries. In some west European countries, grid power generated by biogas accounts for about 10% of the total amount of energy.

沼氣熱電聯產工藝流程
Biogas Cogeneration Process
禽畜養殖糞污，酒廠、食品廠等各種加工廠的有機廢棄物，廚余垃圾，秸稈、菜葉、草、樹葉等農業廢棄物，經處理后進行厭氧發酵，產生沼氣，電熱聯產。電能可上網銷售，余熱可為工業與居民供熱，也可用于溫室種植供熱。另外沼氣也可供工業與民用燃氣，沼液作為液態有機肥，沼渣加工成固態有機肥，可以為農作物種植提供肥料或銷售。
There are various waste that can be used as raw materials for producing biogas, such as agricultural wastes, kitchen garbage, and other organic wastes from livestock farms, breweries and food-processing plants. After proper pretreatment and anaerobic digestion, these organic wastes can be transfer into biogas, and then into electricity. Then power can be sold, while waste heat can be used for heating. Also, biogas can be used as fuel, while slurry can be used for liquid fertilizer, and solid biogas residual for solid fertilizers.
