The amount of electricity generated by an acre of giant grass (also known as “power generation grassâ€) is equivalent to the amount of power generated by three or four tons of coal. On October 14th, the “Research on Key Technologies for Synthetic Utilization of Fungi and Grass,†undertaken by Professor Lin Zhanqi of Fujian Agriculture and Forestry University, passed expert acceptance and opened up a new direction for alleviating the current energy shortage.
Yesterday, Professor Lin took a reporter to visit the giant grass he planted. This grass is up to six or seven meters in diameter and has more than three centimeters in diameter. Each grass is like a bamboo. People stand on the side of the grass, like entering the giant country.
Professor Lin said that this is the “Oasis No. 1†and its root system is developed. The longest, even more than 9 meters, can not only be used to generate electricity, but also have good wind and sand fixation.
It is understood that the “Study on key technologies for comprehensive utilization of grasses and grasses†is a comprehensive research project, including high-yield cultivation techniques for the macro-grasses and grassy grasses.
Lin Zhanxi said that the ordinary grass is as high as two or three meters, and the yield per mu is no more than 5,000 kilograms. The burning of the grass is turned into ash. The giant grass is the highest yielding grass in the world. It can harvest two seasons a year and produce 20,000 kilograms per mu. The amount of electricity generated after the burning of one mu of giant grass is equivalent to the amount of electricity generated after burning 45 ton of raw coal. At present, they have tested a large strain of grass in Lanxi, Zhejiang Province, and have achieved good results.
In addition, this grass has a low requirement for the environment and can be planted on sandy lands, slopes, etc. And they are like leeks. They cut them for longer, and they can cut them for many years at a time. It is also very simple to use electricity to generate electricity. After crushing it with a crusher, it is put into the combustion furnace of a power plant, just as it uses coal to generate electricity.
“Currently, the general economic benefits of macro-grass are general, but it is not always possible to look at the money, and the vision should be long-term.†Lin Zhanxi said that grass-powered power generation has two advantages over coal-fired power generation: a coal is formed after several hundred million years of change. Regenerate, use a little less. The giant grass can be harvested in half a year. Two burning coal will produce carbon dioxide, which will increase the greenhouse effect. An acre of grass can absorb 6 tons of carbon dioxide during the growth process, which is offset by the burning of carbon dioxide, which is almost equal to zero emissions. Therefore, from the perspective of low-carbon environmental protection, grass power generation is very cost-effective, in line with the sustainable development of human society.
According to reports, this type of giant grass has been planted in key demonstration areas established in 18 counties including Longyan Muping and Shunping, Nanping, and has been planted in Ningxia, Inner Mongolia, Tibet and other places. mu. In addition to power generation, there is also a good role in windbreaks and sand stabilization, and good economic and social benefits have been achieved.
The “Research on Key Technologies for Synthetic Utilization of Fungi and Grass†broke through the systematic research on the biological characteristics of grass and grass, laid a solid foundation for large-scale cultivation of grass and grass, and provided a number of advanced and practical technologies for the industrial development of our province. Today, with increasing energy resources, this technology has opened up a new direction for the development and utilization of new energy. (Reporter Liu Qinghua Trainee Li Jianwei Wen/Figure)
Window screening includes Galvanized Iron Wire netting, enameled iron wire netting, aluminum coated iron wire netting, aluminum wire netting, fiberglass wire mesh, PVC wire netting, Stainless Steel Wire netting and PVC coated wire netting. Among these kinds of Window Screen , stainless steel window screening is one of the most important one. Stainless steel window screening is also called Stainless Steel Window Screen or stainless steel insect screen, which is extensively used in today`s life.
