1.NATURAL GAS
Generalized natural gas refers to all natural gases naturally occurring in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcanic gas, coalbed methane, and bio-generated gas). . Narrowly defined natural gas generally includes conventional natural gas and unconventional natural gas. Among them, conventional natural gas refers to natural gas developed from conventional oil and gas reservoirs. Its main component is methane (CH4), and a small amount of ethane, propane and butane. The composition is relatively complex, the specific gravity is about 0.65, lighter than air, colorless, It is tasteless and non-toxic.
Natural gas power generation is the most stable distributed energy supply mode. In recent years, China's natural gas power generation has developed rapidly, the installed capacity has been increasing, and the total installed capacity has been expanding. In the “13th Five-Year Plan”, there is also a clear requirement for the development of the natural gas power generation industry. By 2020, the installed capacity of natural gas power generation will exceed 100 million kilowatts. Natural gas cold, heat and electricity distributed energy is used in development zones, industrial agglomeration zones, industrial parks, commercial centers, transportation hubs, data storage centers, hospitals, schools, etc.
2.GAS
Gas gas, also known as "coal gas", is a coalbed methane that is present in the coal seam and its surrounding rock in an adsorbed and free state. The main component is methane, which is simple in composition and is an unconventional natural gas. Gas is a low-carbon environmentally friendly clean energy source, a culprit in a gas explosion that threatens mining safety, or a greenhouse gas that pollutes the environment. The use of coal mine gas high-efficiency power generation technology can not only promote the comprehensive management of gas safety in China, but also achieve energy conservation and emission reduction. In recent years, it has been greatly promoted by the state and the local. Our gas engine internal combustion engine power generation technology has good adaptability to different gas concentration and gas supply pressure. It can use high concentration gas to generate electricity or low concentration gas to generate electricity.
3.BIOGAS
Biogas is organic matter (such as crop straw, human and animal waste, domestic garbage and organic waste), which is decomposed by biogas microbial fermentation under anaerobic conditions in the biogas tank, and finally formed with methane (CH4) and carbon dioxide (CO2). Mainly mixed gas. Biogas is an important renewable energy source with the characteristics of green, low carbon, clean and renewable. Using biogas to generate electricity, it can solve the rural energy and environmental problems at the same time. Vigorously developing biogas can effectively use rural species to raise livestock and poultry manure and domestic waste, which is an important means to realize China's rural revitalization strategy and beautiful rural construction. Because biogas internal combustion engine has high efficiency, low emission, mature technology, low investment, fast construction, convenient use and maintenance, it is suitable for the wide-ranging distribution of large-scale biogas resources in China, which is in line with the development of eco-agriculture and beautiful construction in China. The rural policy has broad market development prospects. The biogas collection and power generation application process is:
4.LANDFILL GAS
The landfill gas is a mixture of methane and carbon dioxide as a main component produced by the decomposition of microorganisms in the landfill after landfill. The landfill gas composition is complex, and the main components are methane (CH4) and carbon dioxide (CO2), and also contain volatile organic compounds such as H2S, NH3, H2, alkanes and aromatics. The special gas in landfills is a source of greenhouse gas emissions and a source of atmospheric pollution that cannot be ignored. However, since the CH4 content in the landfill gas accounts for about 45% to 60%, and the calorific value is about 18 to 23 MJ/Nm-3, the landfill gas is a clean low-carbon renewable energy source. At present, the main utilization method in the world is to use the internal combustion engine to realize waste turning into treasure. According to the "National Large and Medium-sized City Solid Waste Pollution Environmental Prevention and Control Annual Report" issued by China's environmental protection department, the amount of domestic garbage produced in 246 large and medium-sized cities in China was about 186 million tons in 2015. It is estimated that by 2020, the amount of garbage generated will reach 220 million tons. As early as 2006, China began to promote and apply it, and introduced a series of incentive policies to achieve good economic benefits and environmental benefits. Landfill gas power generation is a “nationally encouraged resource comprehensive utilization” and “renewable energy power generation” project, and can also obtain CDM income. Landfill gas collection and power generation application processes are similar to biogas.
5.BIOMASS GAS
Biomass refers to the combustible gas formed by pyrolysis of solid biomass by high temperature under controlled oxygen content. The main components are H2, CO, CH4, CmHn, CO2, N2, etc. Carbon-friendly clean energy. The raw materials may be almost all biomass wastes of agricultural and forestry industries such as straw, wood chips, rice husks, distiller's grains and dregs. Biomass gas power generation is the biomass energy utilization technology with the highest comprehensive utilization of biomass energy and the most industrialized development potential.
