What components do biogas generator units have when burning:

1.材料來歷廣泛。沼氣發(fā)電機組的首要燃燒成分是甲烷，由甲烷產生菌厭氧消化有機物產生。所以只需有 機物存在的當?shù)兀倥湟赃m宜的環(huán)境條件，就會有甲烷的生成。例如人畜的糞便、工業(yè)廢水、廢物填埋場、農作物秸稈等都可用做沼氣產生的原材料。

1. The materials come from a wide range of sources. The primary combustion component of biogas generator set is methane, which is produced by anaerobic digestion of organic substances by methane producing bacteria. Therefore, only the place where organic matters exist, combined with appropriate environmental conditions, will have methane generation. For example, human and animal manure, industrial wastewater, waste landfill, crop straw, etc. can be used as raw materials for biogas production.

2.可再生，污染少。用沼氣進行發(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，石油還可運用40~50年，天然氣還可運用60~70年，煤炭則能堅持225年左右?？梢姡瘎恿﹄x咱們而去的日子已不遠。而以沼氣為代表的生物質動力的壽數(shù)幾乎是無限的，只需太陽存在，沼氣也將存在。

2. Renewable, less pollution. Do not worry about the day when biogas will be used for power generation. According to statistics, by the end of 2002, the proven reserves of international remaining oil were 140.704 billion tons. According to the calculation of internationally 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，只需有沼氣產生的當?shù)氐鬃由隙伎梢赃M行發(fā)電。不像水電有必要樹立在水力資源豐富的當?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?shù)?，因為太陽能發(fā)電要占用很多的土地，有必要考慮項目的經濟性，現(xiàn)在建的太陽能電站一般都在沙漠。

3. Less constrained by environment. The planning of biogas power generation is relatively small, and the requirements on the site are not high. Power generation can be carried out only on the local basis where biogas is generated. Unlike hydropower, it is necessary to set up in a place with rich water resources, and also consider the impact of hydropower on the surrounding ecological environment; Solar power generation should be built in remote places with long sunshine hours. Because solar power generation takes up a lot of land, it is necessary to consider the economy of the project. Currently built solar power stations are generally in the desert.

沼氣發(fā)電機組通過混合器與空氣混合，經增壓、中冷、自動調節(jié)閥后進入燃燒室，可適應低壓燃燒。整機自動化程度高，機組經濟性、可靠性、安全性、適應性等方針抵達水平。

The biogas generator unit is mixed with air through a mixer, and enters the combustion chamber after being pressurized, intercooled, and automatically controlled to adapt to low-pressure combustion. The whole machine has a high degree of automation, and its economy, reliability, safety, adaptability and other policies have reached the international advanced level.

沼氣發(fā)電機組里邊沼氣功率掩蓋20-2000KW，還有天然氣、秸稈氣、瓦斯、煤層氣、焦爐煤氣發(fā)電機組及動力機組。

The biogas power in the biogas generator unit covers 20-2000KW, and there are also natural gas, straw gas, gas, coalbed gas, coke oven gas generator units and power units.

根據(jù)村莊的地域和材料資源的特色，在村莊大力推廣新動力是處理村莊動力問題的一條重要思路適用于村莊區(qū)域的清潔新動力有很多種，其中較為老到的有風能太陽能沼氣發(fā)電等幾種風能和太陽能是一種清潔的可再生新動力，但它們的共同點是對風力或日照資源的依賴性十分高，而我國中部的大部分區(qū)域則不具有杰出的風能和太陽能運用的資源條件，而且風能和太陽能設備的運用壽數(shù)低價格高。

According to the characteristics of the region and material resources of the village, vigorously promoting new power in the village is an important way to deal with the problem of village power. There are many kinds of clean new power that are applicable to the village area, among which wind energy, solar energy, biogas power generation and other wind and solar energy are relatively old. They are clean and renewable new power, but their common point is that they are highly dependent on wind or sunlight resources, However, most regions in the central part of China do not have outstanding resource conditions for the use of wind energy and solar energy, and the use of wind energy and solar energy equipment is low in life and high in price.

沼氣發(fā)電是一種運用生物質動力的可再生新動力運用技能與一臺相同功率的小型沼氣發(fā)電機組設備相比，小型風力發(fā)電機組的設備價格是其價格的3~4 倍;一套太陽能發(fā)電設備的價格是其價格的22 倍以上小型沼氣發(fā)電只需要締造沼氣池，其建池本錢略相當于小型沼氣發(fā)電設備的本錢，現(xiàn)在村莊區(qū)域已經有不少戶用沼氣池，而且均由國家財政補貼支撐締造而沼氣池的材料首要是人畜糞便農作物秸稈等廢料，本錢底子為零除此之外，沼氣發(fā)電相對于風能和太陽能還具有以下一些長處：

Biogas power generation is a renewable new power application skill using biomass power. Compared with a small biogas generator set with the same power, the equipment price of small wind turbine generator set is 3~4 times of its price; The price of a set of solar power generation equipment is more than 22 times of its price. For small biogas power generation, only biogas digesters need to be built, and the cost of building the digesters is slightly equivalent to the cost of small biogas power generation equipment. Now there are many biogas digesters for households in the village area, and they are all built with the support of national financial subsidies. The materials of biogas digesters are mainly human and livestock manure, crop straw and other wastes, and the cost base is zero, Compared with wind energy and solar energy, biogas power generation also has the following advantages:

1.運用便當，不受氣候和環(huán)境的限制。

1. It is easy to use and is not restricted by climate and environment.

2.材料來自生活生產廢料，一同協(xié)助處理了廢料形成的環(huán)境污染問題。

2. The materials are from domestic and production wastes, and they have helped to deal with the environmental pollution caused by wastes.

3.沼氣池產生的沼渣沼液是農家肥，完成了農家廢物的循環(huán)運用

3. The biogas residue produced by the biogas digester is farm manure, which completes the recycling of farm waste

4.小型沼氣發(fā)電設備細巧，搬運便當，在沼氣輸氣管可達當?shù)乜删徒鼮樾⌒碗妱愚r用機具供電。

4. Small biogas power generation equipment is delicate and easy to handle. It can supply power for small electric agricultural machines and tools nearby when the biogas transmission pipe reaches the local area.

1.所選沼氣發(fā)電機組的功用和質量有必要契合有關標準要求

1. The function and quality of the selected biogas generator unit must meet the requirements of relevant standards

沼氣發(fā)電機組廣泛用于電信、財政金融部分、醫(yī)院、學校、商業(yè)等部分、工礦企業(yè)和居處的應急備用電源，軍事與野外作業(yè)、車輛與船舶等特別用途的獨立電源。

Biogas generator sets are widely used for emergency standby power supply of telecommunications, financial and financial sectors, hospitals, schools, commerce and other sectors, industrial and mining enterprises and residences, and independent power supply for special purposes such as military and field operations, vehicles and ships.

作為通訊用沼氣發(fā)電機組，有必要抵達GB2820-1997中G3級或G4級規(guī)矩的要求，一同要通過我國職業(yè)主管部分所樹立的通訊電源設備質量監(jiān)督查驗中心的嚴峻查驗。
