What components do biogas generator units have when burning:

1.材料来历广泛。沼气发电机组的首要燃烧成分是甲烷，由甲烷产生菌厌氧消化有机物产生。所以只需有 机物存在的当地，再配以适宜的环境条件，就会有甲烷的生成。例如人畜的粪便、工业废水、废物填埋场、农作物秸秆等都可用做沼气产生的原材料。

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。用沼气进行发电，不用忧虑会有枯竭的一天。据统计，至2002年底剩余石油探明储量为1407.04亿吨。根据已探明的化石动力储量核算，石油还可运用40~50年，天然气还可运用60~70年，煤炭则能坚持225年左右。可见，化石动力离咱们而去的日子已不远。而以沼气为代表的生物质动力的寿数几乎是无限的，只需太阳存在，沼气也将存在。

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.受环境束缚小。沼气发电的规划比较小，对场所的要求不高，只需有沼气产生的当地底子上都可以进行发电。不像水电有必要树立在水力资源丰富的当地,而且还要考虑电站对周围生态环境的影响;太阳能发电要建在日照时间长且比较偏僻的当地，因为太阳能发电要占用很多的土地，有必要考虑项目的经济性，现在建的太阳能电站一般都在沙漠。

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.

沼气发电机组通过混合器与空气混合，经增压、中冷、自动调节阀后进入燃烧室，可适应低压燃烧。整机自动化程度高，机组经济性、可靠性、安全性、适应性等方针抵达水平。

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.

沼气发电机组里边沼气功率掩盖20-2000KW，还有天然气、秸秆气、瓦斯、煤层气、焦炉煤气发电机组及动力机组。

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.

根据村庄的地域和材料资源的特色，在村庄大力推广新动力是处理村庄动力问题的一条重要思路适用于村庄区域的清洁新动力有很多种，其中较为老到的有风能太阳能沼气发电等几种风能和太阳能是一种清洁的可再生新动力，但它们的共同点是对风力或日照资源的依赖性十分高，而我国中部的大部分区域则不具有杰出的风能和太阳能运用的资源条件，而且风能和太阳能设备的运用寿数低价格高。

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.

沼气发电是一种运用生物质动力的可再生新动力运用技能与一台相同功率的小型沼气发电机组设备相比，小型风力发电机组的设备价格是其价格的3~4 倍;一套太阳能发电设备的价格是其价格的22 倍以上小型沼气发电只需要缔造沼气池，其建池本钱略相当于小型沼气发电设备的本钱，现在村庄区域已经有不少户用沼气池，而且均由国家财政补贴支撑缔造而沼气池的材料首要是人畜粪便农作物秸秆等废料，本钱底子为零除此之外，沼气发电相对于风能和太阳能还具有以下一些长处：

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.运用便当，不受气候和环境的限制。

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

2.材料来自生活生产废料，一同协助处理了废料形成的环境污染问题。

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

3.沼气池产生的沼渣沼液是农家肥，完成了农家废物的循环运用

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

4.小型沼气发电设备细巧，搬运便当，在沼气输气管可达当地可就近为小型电动农用机具供电。

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.所选沼气发电机组的功用和质量有必要契合有关标准要求

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

沼气发电机组广泛用于电信、财政金融部分、医院、学校、商业等部分、工矿企业和居处的应急备用电源，军事与野外作业、车辆与船舶等特别用途的独立电源。

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.
