What are the components of the biogas generator set when it burns:
1. The materials come from a wide range of sources. The primary combustion component of biogas generators is methane, which is produced by anaerobic digestion of organic matter by methane-producing bacteria. Therefore, only the place where the organic matter exists, coupled with suitable environmental conditions, will generate methane. For example, human and livestock manure, organic industrial wastewater, waste landfills, crop straws, etc. can all be used as raw materials for biogas production.
2. Renewable, less pollution. If you use biogas to generate electricity, you don’t have to worry that it will be exhausted one day. According to statistics, by the end of 2002, the international proved reserves of remaining oil were 140.704 billion tons. According to the internationally proven fossil power reserves, oil can be used for 40-50 years, natural gas can be used for 60 to 70 years, and coal can be used for about 225 years. It can be seen that the fossil power is not far from the day when we are gone. The life span of biomass power represented by biogas is almost unlimited. As long as the sun exists, biogas will also exist.
3. Less constrained by the environment. The planning of biogas power generation is relatively small, and the requirements for the site are not high. Power generation can be carried out only on the local foundation where biogas is generated. Unlike hydropower, it is necessary to establish in a place rich in hydropower resources, and also consider the impact of the power station on the surrounding ecological environment; solar power generation should be built in a remote place with long sunshine hours, because solar power generation takes up a lot of land, so it is necessary Considering the economics of the project, the solar power stations currently being built are generally in the desert.
The biogas generator set is mixed with air through a mixer, and enters the combustion chamber after pressurizing, intercooling, and automatic regulating valve, which can adapt to low-pressure combustion. The whole machine has a high degree of automation, and the unit economy, reliability, safety, adaptability and other policies have reached the international advanced level.
The biogas power in the biogas generator set covers 20-2000KW, and there are natural gas, straw gas, gas, coal bed methane, coke oven gas generator sets and power units.
According to the characteristics of the village’s region and material resources, vigorously promoting new power in the village is an important idea to deal with the problem of village power. There are many new clean power applicable to the village area, among which the older ones include wind energy, solar energy, and biogas power generation. Wind energy and solar energy are a kind of clean and renewable new power, but their common point is that they are very dependent on wind or sunlight resources, while most areas in central my country do not have outstanding resource conditions for the use of wind and solar energy. Moreover, the service life of wind energy and solar energy equipment is low and the price is high.
Biogas power generation is a kind of renewable new power using biomass power. Compared with a small biogas generator set with the same power, the equipment price of a small wind generator set is 3~4 times its price; a set of solar power generation The price of the equipment is more than 22 times its price. Small-scale biogas power generation only needs to build a biogas digester. The cost of building a pool is slightly equivalent to the cost of small-scale biogas power generation equipment. There are already many household biogas digesters in the village area, and they are all funded by the state. Subsidies support the creation of biogas digesters. The main materials for biogas digesters are human and animal manure, crop straws and other waste materials. In addition, the cost base is zero. In addition, biogas power generation has the following advantages compared with wind and solar energy:
1. Easy to use, not restricted by climate and environment.
2. The materials come from domestic production wastes, and together they help deal with the environmental pollution problems caused by wastes.
3. The biogas residue produced by the biogas digester is excellent farmyard manure, which completes the recycling of farmyard waste.
4. The small biogas power generation equipment is delicate and easy to carry. When the biogas pipeline can reach the local area, it can supply power for small electric agricultural machinery nearby.
1. The function and quality of the selected biogas generator set must meet the requirements of relevant standards
Biogas generator sets are widely used in telecommunications, financial departments, hospitals, schools, commerce, etc., industrial and mining enterprises and residential emergency backup power sources, military and field operations, vehicles and ships, and other special-purpose independent power sources.
As a communication biogas generator set, it is necessary to meet the requirements of the G3 or G4 regulations in GB2820-1997, and must pass the severe inspection of the communication power supply equipment quality supervision and inspection center established by the professional management department of our country.
As a biogas generator set for military communications, it is necessary to reach the relevant GB2820-1997, GJB-related standards and the regulations of the “Quality Inspection Standards for Communication Power Equipment” drafted by relevant parts of the military, and to pass the severe inspection of the equipment quality by the relevant organizations.
2. The primary factors that should be considered in the selection of biogas generator sets
The factors that should be considered in the selection of a biogas generator set are primarily mechanical and electrical functions, the purpose of the unit, load capacity and modification planning, and automation functions.
(1) The purpose of the unit. Because biogas generator sets can be used in three situations: common use, standby and emergency. Therefore, different applications have different requirements for diesel generator sets.
(2) Load capacity. The load capacity and load modification plan should be selected according to different uses, and the single-unit capacity of the biogas generator and the capacity of the standby biogas generator set should be determined.
(3) The operating environmental conditions of the unit (primarily refer to the altitude and climatic conditions)
(4) Selection of biogas generator set
(5) Selection of generator and excitation mode
