沼氣發(fā)電機(jī)組燃燒時有哪些成分：
What are the components of biogas generator set during combustion:
1.材料來歷廣泛。沼氣發(fā)電機(jī)組的首要燃燒成分是甲烷，由甲烷產(chǎn)生菌厭氧消化有機(jī)物產(chǎn)生。所以只需有機(jī)物存在的當(dāng)?shù)?，再配以適宜的環(huán)境條件，就會有甲烷的生成。例如人畜的糞便、有機(jī)工業(yè)廢水、廢物填埋場、農(nóng)作物秸稈等都可用做沼氣產(chǎn)生的原材料。
1. materials come from a wide range of sources. The primary combustion component of the biogas generator set is methane, which is produced by anaerobic digestion of organic matter by methane producing bacteria. Therefore, as long as the local organic matter exists, coupled with appropriate environmental conditions, methane will be generated. For example, human and animal feces, organic industrial wastewater, waste landfills, crop straw, etc. can be used as raw materials for biogas production.
2.可再生，污染少。用沼氣進(jìn)行發(fā)電，不用憂慮會有枯竭的一天。據(jù)統(tǒng)計，至2002年底剩余石油探明儲量為1407.04億噸。根據(jù)已探明的化石動力儲量核算，石油還可運(yùn)用40~50年，天然氣還可運(yùn)用60~70年，煤炭則能堅持225年左右。可見，化石動力離咱們而去的日子已不遠(yuǎn)。而以沼氣為代表的生物質(zhì)動力的壽數(shù)幾乎是無限的，只需太陽存在，沼氣也將存在。
2. renewable and less pollution. With biogas for power generation, there is no need to worry that it will run out one day. According to statistics, by the end of 2002, the proved reserves of international remaining oil were 140.704 billion tons. According to the international proven fossil power reserves, 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 power is not far away from us. The life span of biomass power represented by biogas is almost unlimited. As long as the sun exists, biogas will also exist.
3.受環(huán)境束縛小。沼氣發(fā)電的規(guī)劃比較小，對場所的要求不高，只需有沼氣產(chǎn)生的當(dāng)?shù)氐鬃由隙伎梢赃M(jìn)行發(fā)電。不像水電有必要樹立在水力資源豐富的當(dāng)?shù)?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當(dāng)?shù)?，因?yàn)樘柲馨l(fā)電要占用很多的土地，有必要考慮項(xiàng)目的經(jīng)濟(jì)性，現(xiàn)在建的太陽能電站一般都在沙漠。
3. less constrained by the environment. The planning of biogas power generation is relatively small, and the requirements for places are not high. Power generation can be carried out only on the local base where biogas is generated. Unlike hydropower, it is necessary to set up in the local area with abundant hydraulic resources, and the impact of the power station on the surrounding ecological environment should be considered; Solar power generation should be built in remote areas with long sunshine time. Because solar power generation takes up a lot of land, it is necessary to consider the economy of the project. Currently, solar power stations are generally built in the desert.
沼氣發(fā)電機(jī)組通過混合器與空氣混合，經(jīng)增壓、中冷、自動調(diào)節(jié)閥后進(jìn)入燃燒室，可適應(yīng)低壓燃燒。整機(jī)自動化程度高，機(jī)組經(jīng)濟(jì)性、可靠性、安全性、適應(yīng)性等方針抵達(dá)水平。
The biogas generator unit is mixed with air through a mixer and enters the combustion chamber after being pressurized, intercooled and automatically regulated, which can adapt to low-pressure combustion. The whole machine has a high degree of automation, and its economy, reliability, safety and adaptability have reached the international advanced level.
沼氣發(fā)電機(jī)組里邊沼氣功率掩蓋20-2000KW，還有天然氣、秸稈氣、瓦斯、煤層氣、焦?fàn)t煤氣發(fā)電機(jī)組及動力機(jī)組。
The biogas power in the biogas generator set is 20-2000kw, as well as natural gas, straw gas, gas, coalbed methane, coke oven gas generator set and power unit.
