  今天我们济南沼气发电机组厂家小编给大家介绍的是沼气发电机组的主要燃烧成分是什么?

  Today, we Ji'nan biogas generator set of small series to introduce to you is the main component of the combustion of methane generating units is what?

  沼气发电机组的主要燃烧成分:

  Main combustion components of biogas generating set:

  (1)可再生,污染少。用沼气进行发电,不用担心会有枯竭的一天。据统计,至2002年底世界剩余石油探明储量为1407.04亿吨。根据世界已探明的化石能源储量推算,石油还可使用40~50年,天然气还可使用60~70年,煤炭则能维持225年左右。可见,化石能源离我们而去的日子已不远。而以沼气为代表的生物质能源的寿命几乎是无限的,只要太阳存在,沼气也将存在。

  renewable, less pollution. Use biogas to generate electricity, do not have to worry about the depletion of the day. According to statistics, by the end of 2002 the world's remaining oil proven reserves of 1407.04 tons. According to the world's proven reserves of fossil fuels, oil can also be used 40~50 years, natural gas can also be used in 60~70, the coal can be maintained for about 225 years. It can be seen that the fossil energy is not far away from us. And biogas as the representative of the life of the biomass energy is almost unlimited, as long as the sun exists, there will be.

  (2)原料来源广泛。沼气发电机组的主要燃烧成分是甲烷,由甲烷产生菌厌氧消化有机物产生。所以只要有机物存在的地方,再配以适合的环境条件,就会有甲烷的生成。例如人畜的粪便、有机工业废水、垃圾填埋场、农作物秸秆等都可用做沼气产生的原材料。目前我国生猪、家禽和牛等畜禽养殖业粪便排放量约18亿吨,实际排出污水总量约200亿吨,可生产沼气约500亿立方米;全国工业企业每年排放的(可转化为沼气)有机废水和废渣约25亿立方米,可生产沼气约100亿立方米。今后随着畜禽养殖业和工业企业的发展,沼气的生产量还会增加。以一个60万人口的城镇为例,每天产生垃圾约600吨,产生沼气1万立方左右,可以供1000千瓦的燃气发电机组进行发电。且城市越大,垃圾中含的有机物越多,产生的沼气量也就越多。我国人口众多,适合做这样项目的垃圾填埋场也很多。因此,沼气的来源十分广泛。

  a wide range of raw materials. The main combustion component of biogas generating set is methane, which is produced by anaerobic digestion of anaerobic digestion of methane producing bacteria. So as long as there is organic matter in place, coupled with suitable environmental conditions, there will be the formation of methane. For example, human and livestock manure, organic industrial wastewater, landfill, crop straw and so can be used as raw material for biogas production. At present about 18 million tons of China's pig, poultry and cattle and other livestock and poultry manure emissions and actual discharge amount of waste water of about 200 million tons, about 500 billion cubic meters of methane production; industrial enterprises of the national annual emissions (which can be translated into biogas) organic waste water and waste residue of about 25 billion cubic meters, about 100 billion cubic meters of methane production. In the future, with the development of livestock and poultry industry and the development of industrial enterprises, the production of methane will increase. With a 600 thousand population of the town as an example, about 600 tons of garbage generated every day, about 10 thousand cubic meters of methane, can be used for 1000 kilowatts of gas generating units to generate electricity. And the greater the city, the more organic matter contained in the garbage, the more the amount of methane generated. Our country has a large population and is suitable for such projects. Therefore, the source of methane is very extensive.

  (3)受环境限制小。沼气发电机组的规模比较小,对场地的要求不高,只要有沼气产生的地方基本上都可以进行发电。不像水电必须建立在水力资源丰富的地方,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地方,因为太阳能发电要占用大量的土地,必须考虑项目的经济性,现在建的太阳能电站一般都在沙漠。

  limited by the environment. The scale of biogas power generation is relatively small, the requirements of the site is not high, as long as there is a place where the biogas generated can be basically electricity generation. Unlike hydropower must be built where the water is rich in resources, but also considers the influence of power station to the surrounding ecological environment; solar power to built in the sunshine for a long time and more remote places, because solar power to occupy a lot of land must be considered project economics, now to build solar power plants 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、适应性等指标达到国际先进水平。

  The biogas generating set is mixed with the air through a mixer, and enters the combustion chamber after being pressurized, the middle cooling and the automatic control valve, which can be adapted to the low pressure combustion. The machine has high degree of automation, economic, reliability, security, adaptability and other indicators to reach the international advanced level.
