Biomass power generation

09.27, 2020
Biomass power generation is a kind of renewable energy power generation that uses the biomass energy of biomass. It includes direct combustion power generation of agricultural and forestry waste, gasification power generation of agricultural and forestry waste, waste incineration power generation, and landfill gas power generation , Biogas power generation. The world's biomass power generation originated in the 1970s. At that time, after the global oil crisis broke out, Denmark began to actively develop clean renewable energy and vigorously promoted biomass power generation such as straw. Since 1990, biomass power generation has been vigorously developed in many European and American countries.
China is a large agricultural country with abundant biomass resources. Various crops produce more than 600 million tons of straw each year, of which about 400 million tons can be used as energy sources. The total biomass of the country’s forests is about 19 billion tons, with 900 million available. Tons, the total amount that can be used as energy is about 300 million tons. If used effectively, the development potential will be huge.
In order to promote the development of biomass power generation technology, since 2003, the state has successively approved and approved 3 straw power generation demonstration projects in Jinzhou, Shandong, Shanxian, Shandong, and Rudong, Jiangsu, promulgated the "Renewable Energy Law", and implemented biomass Power generation preferential feed-in tariffs and other related supporting policies have enabled the rapid development of biomass power generation, especially sweet sorghum straw power generation.
According to the development goals set out in the national "Eleventh Five-Year Plan" outline, a biomass power generation capacity of 5.5 million kilowatts will be built in the future. The published "Medium and Long-term Development Plan for Renewable Energy" also determines the biomass power generation capacity of 30 million kilowatts by 2020. Development goals. In addition, the state has decided to arrange funds to support the construction of industrial service systems such as renewable energy technology research and development, equipment manufacturing, testing and certification. In general, the biomass power generation industry has broad development prospects.
As competition in the biomass power generation industry continues to intensify, mergers and acquisitions and capital operations among large biomass power generation companies have become more frequent. Excellent domestic biomass power generation companies are paying more and more attention to research on the industry market, especially for corporate development. In-depth study of changes in environment and customer demand trends. Because of this, a large number of outstanding domestic biomass power generation companies have risen rapidly and have gradually become leaders in the biomass power generation industry!
my country's biomass energy resources are very rich, and the prospects for the development of the biomass power generation industry are broad. On the one hand, China has 1.8 billion mu of sown area of ​​crops, producing about 700 million tons of material annually. Equivalent to 350 million tons of standard coal. In addition, agricultural product processing wastes, including rice husks, corn cobs, peanut husks, bagasse and cottonseed husks, are also important biomass resources. On the other hand, my country's existing forest area is about 195 million hectares, the forest coverage rate is 20.36%, and the annual biomass resources are about 800 million to 1 billion tons.
At the same time, the development of biomass power generation and the implementation of coal substitution can significantly reduce carbon dioxide and sulfur dioxide emissions and produce huge environmental benefits. Compared with traditional fossil fuels, biomass energy is a clean fuel, and carbon dioxide emissions after combustion belong to the natural carbon cycle and do not cause pollution. According to estimates, operating a 25,000 kW biomass power generating unit can reduce carbon dioxide emissions by about 100,000 t/a compared with the same type of thermal power unit.
By 2025, among renewable energy, biomass power generation will dominate. In the future, the use of biomass renewable energy for power generation has become an important way to solve energy shortages.
In addition, my country has more than 54 million hectares of land suitable for forestry, which can be combined with ecological construction to grow crops. These are China's advantages in developing the biomass power generation industry. The development of the biomass power generation industry is an important way to build a stable, economic, clean and safe energy supply system and break through the resource and environmental constraints of economic and social development.
