As for biogas, a new and clean energy, its application prospect is very broad in the future because of its outstanding characteristics of high energy, energy saving, safety and environmental protection. In China, the technology and equipment of biogas production, collection, storage and utilization are becoming more and more mature, so why more and more people choose biogas generator set? This is inseparable from its own characteristics.

1、可再生，污染少。用沼氣進行發(fā)電，不用擔心會有枯竭的。據(jù)統(tǒng)計，至2002年底世界剩余石油探明儲量為1407.04億噸。根據(jù)世界已探明的化石能源儲量推算，石油還可使用40~50年，天然氣還可使用60~70年，煤炭則能維持225年左右?？梢姡f明化石能源離我們而去的日子已不遠。而以沼氣為代表的生物質能源的壽命幾乎是無限的，只要太陽存在，沼氣也將存在。

1. Renewable, less pollution. Using biogas to generate electricity, there is no need to worry that it will be exhausted one day. According to statistics, by the end of 2002, the world's remaining proven oil reserves were 140.704 billion tons. According to the proven fossil energy reserves in the world, oil can be used for another 40-50 years, natural gas for another 60-70 years, and coal for about 225 years. It can be seen that fossil energy is not far away from us. The life of biomass energy represented by biogas is almost unlimited. As long as the sun exists, biogas will also exist.

2、原料來源廣泛。沼氣發(fā)電機組的主要燃燒成分是甲烷，由甲烷產生菌厭氧消化有機物產生。所以只要有機物存在的地方，再配以適合的環(huán)境條件，就會有甲烷的生成。例如人畜的糞便、有機工業(yè)廢水、垃圾填埋場、農作物秸稈等都可用做沼氣產生的原材料。今后隨著畜禽養(yǎng)殖業(yè)和工業(yè)企業(yè)的發(fā)展，沼氣的生產量還會增加。以一個60萬人口的城鎮(zhèn)為例，每天產生垃圾約600噸，產生沼氣1萬立方左右，可以供1000千瓦的燃氣發(fā)電機組進行發(fā)電。且城市越大，垃圾中含的有機物越多，產生的沼氣量也就越多。我國人口眾多，適合做這樣項目的垃圾填埋場也很多。因此，沼氣的來源十分廣泛。

2. The sources of raw materials are wide. The main combustion component of biogas generator set is methane, which is produced by anaerobic digestion of organic matter by methane producing bacteria. So as long as the organic matter exists in the place, coupled with suitable environmental conditions, there will be methane generation. For example, human and animal manure, organic industrial wastewater, landfill, crop straw and so on can be used as raw materials for biogas production. In the future, with the development of animal husbandry and industrial enterprises, the production of biogas will increase. Take a town with a population of 600000 as an example, it produces about 600 tons of garbage and about 10000 cubic meters of biogas every day, which can be used by 1000 kW gas-fired generating units for power generation. And the larger the city is, the more organic matter is contained in the garbage, and the more biogas is produced. China has a large population, so there are many landfills suitable for such projects. Therefore, the source of biogas is very extensive.

3、受環(huán)境限制小。沼氣發(fā)電機組的規(guī)模比較小，對場地的要求不高，只要有沼氣產生的地方基本上都可以進行發(fā)電。不像水電必須建立在水力資源豐富的地方，而且還要考慮電站對周圍生態(tài)環(huán)境的影響；太陽能發(fā)電要建在日照時間長且比較偏僻的地方，因為太陽能發(fā)電要占用大量的土地，必須考慮項目的經(jīng)濟性.

3. Limited by the environment. The scale of biogas generating unit is relatively small, and the requirements for the site are not high. As long as there is biogas generating place, it can basically generate electricity. Unlike hydropower, which must be built in a place rich in water resources, but also consider the impact of the power station on the surrounding ecological environment; Solar power generation should be built in remote places with long sunshine time, because solar power generation takes up a lot of land, so the economy of the project must be considered
