To greet the dawn of the twenty-first century - China's current situation and development trend of coal preparation


Environment. The mine has been done in the past a lot of work, accumulated a lot of experience and technology, but must be further improved and facilities. Better approach is to use agents rattan reinforcement to do after sulfur coal or boiling furnace fuel, but also the production of high ash coal-water slurry or oil agglomeration,[link widoczny dla zalogowanych], selective flocculation recovery of low ash coal and so on. 5) development of efficient, high-quality preparation equipment, improve mechanical and electrical integration. Preparation to develop advanced equipment, reliable is the key. This gap between China and developed countries is clear, therefore, also on a number of key preparation equipment abroad. In the next five years, the gap should be narrowed, based on domestic, improve automation and mechatronics is the development direction of our industry, we need to catch up with the pace of national development in other industries. 6) The further development of the coal preparation plant assembled. In recent years, through the efforts,[link widoczny dla zalogowanych], the concept of assembly-type coal preparation plant and design ideas have been L_-_ ��. t �� �� �� - 't, 1 {2001, No. 1 and the comprehensive utilization of coal processing coALPROCESSING & 4PREI ~ EN5IVEuTILIZATIONNo. 1,2001 Several of urban air gasification Guo East, Gao silly idea (Yima coal gasification branch, Henan 472300) bands playing; discussed as some of City Gas Dance gas such as natural gas, liquefied petroleum gas, coke oven gas,[link widoczny dla zalogowanych], coal gas gas shame dance features. Off quantifier:} Gas City Gas in the circle dance characterized CLC: TQ5l7.1; TQ517.2 Document code: B Article ID :1005 -8397 (2001) 01-0006-02 With industrial development and people's living standards improve, especially with the development of urban construction, high-rise buildings increased, changing the fuel structure, increase the gasification rate of urban residents has become a pressing need. In China for the city's main source of coal gasification are: natural gas, liquefied petroleum gas, coke oven gas, coal gas and so on. A tender wife, the main component of natural gas if the gas methane content of 90 or more units also have a small amount of H. s, cO, N, etc., heat value of 33.44 ~ 36.34MJ / m. . As a safe, clean, rich in energy, natural gas increasingly attracted worldwide attention, was hailed as a 2l century, energy, It is an ideal chemical feedstock, fuel gas, and is an ideal city residents gas. China has abundant natural gas resources, wider distribution. Date :2000-12 received a lotus root u of the dielectric cylinder: Guo East (1965 a), male, civil rights, County of Henan, Henan Gas Corporation Group eyes Yima coal gasification production technology division at the engineer, bachelor; Phone 0398 -5625398. In recent years, natural gas exploration and development of the western region has achieved a breakthrough. Has formed a Xinjiang, Qinghai,[link widoczny dla zalogowanych], Ningxia, Sichuan, Chongqing, four air area, has proven reserves of the Tarim Exploration Area 5679X10. m. Qaidam exploration area reserves 1300Xi0IT1, Ningxia exploration area reserves 3235X10. m. , JlI Yu exploration area reserves 5378X1m. Reserves in western China is expected to have 26 �� 10 \in our energy mix jumped from the current 2 to 8.'s vast natural gas resources in the distribution is very uneven, in our densely populated, industrial reserves of less developed eastern regions, has been unable to meet the needs of its industrial and civilian population of l and few industries, it plays a less developed country in the western region onshore natural gas resources 86.7. This phenomenon has seriously affected the development of natural gas resources with the power ��, �� power to gas development makes it difficult to use. In order to accelerate the rational use of natural gas resources in the western region and accelerate the development and utilization of natural gas, China has begun a national gas pipeline network planning and construction, and gradually formed in Xinjiang, Qinghai, Shaanxi �� �� �� ... �� �� �� I �� �� �� �� ~ ... �� �� �� �� �� ... ... ... �� �� �� ... �� ... �� ... �� ... �� ... �� ... �� �� �� �� �� �� �� �� �� �� ... �� ... �� �� ... �� �� �� �� �� I ...
