The term "clean coal" was coined by Drew Lewis (United States) and William Davis (Canada), special envoys of the United States and Canada in the early 1980s to settle the acid rain between the two countries. The meaning of Clean Coal Technology (CCT) is the general term for new technologies such as coal processing, combustion, conversion, and pollution control that aim to reduce pollution and improve efficiency. Currently, it has become one of the leading technologies for solving environmental problems in all countries in the world, and it is also an important field for high-tech international competition.
Due to the characteristics of coal mining and utilization in China, China's clean coal technology and foreign clean coal technologies are different in their focus on combustion and power generation technology. Covering coal from coal mining to the entire process of utilization is a goal in coal development and utilization. The general term for new technologies such as coal processing, combustion, conversion, and pollution control that reduce pollution and improve efficiency.
What is clean coal technology?
Clean coal technology refers to the entire process from coal mining to utilization, and it mainly deals with new technologies such as processing, conversion, propane gas, and pollution control that reduce pollutant emissions and increase utilization efficiency, including clean production technology, clean processing technology, and high efficiency. Clean conversion technology, high-efficiency clean propane and power generation technologies, and coal-fired pollution emission control technologies.
Development of Coal Chemical Industry in China
In 2008, China's coal chemical industry continued to develop in an orderly manner, the coal chemical industry development policy was gradually improved, pilot applications of coal-based methanol and coal-based dimethyl ether made gratifying progress, production capacity was further released, and new coal chemical products gradually came to market. Accepted by the market. With the intensification of the financial crisis, China's coal chemical industry is facing cost pressures and the industry is slowing down. Since the national policy still supports the development of coal chemical industry in general, energy conservation and emission reduction have become a trend. Therefore, although China's coal chemical industry suffers short-term difficulties, the prospects are still considerable.
The new coal chemical industry mainly produces clean energy and alternative petrochemical products such as diesel, gasoline, aviation kerosene, liquefied petroleum gas, ethylene raw materials, polypropylene raw materials, alternative fuels (methanol, dimethyl ether), etc. The combination of chemical technology and the formation of coal-energy and chemical industry integration emerging industries. The coal energy and chemical industry will play an important role in the sustainable use of energy in China and will be an important development direction in the next 20 years. This will be of great significance for China in reducing the environmental pollution caused by coal combustion and reducing China’s dependence on imported oil. It can be said that the coal chemical industry is facing new market demand and development opportunities in China.
High speed shutter door is a rapid operating, anti-crash shutter door for indoor application . The most advantage of this door is that the opening/closing speed can reach to 0.6-1.8m/s, really fast action a lot than tranditional rollling shutter door. short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
High speed door can be easily installed, economical,quiet and efficient with electromechanical drive.
This door quickly though in/out open gate, ideal for warehouses,factories, hangars use, widths can be from 2m to 20 meters.
The material of this door are variety: PVC curtain to keep the insdie clean, heavy duty aluminum door with wind-resisitant function can wrok in heavy windy weather, and also the freezer door can be used in cold warehouse or somewhere like that.
Including models are:PVC High Speed Door, Aluminum Spiral High Speed Door, Self-Recovery repair door, Cold Storage Room Fast Door.
