Clean utilization of coal is a priority option for emission reduction and pollution control.
At present, China is still in the stage of accelerating industrialization, and coal consumption accounts for 2/3 of China's primary energy consumption, which is an important primary energy. Realistic factors such as the resource endowment characteristics of "rich coal, less oil and gas shortage" determine that coal utilization will still dominate energy consumption for a long time in the future.
While providing energy security for the sustained and stable development of China's economy and society, the problems of resources, environment, ecology and security brought by coal are becoming more and more prominent. In recent years, the "heating haze" that appears in autumn and winter every year has made coal bear the infamy of "haze culprit. In order to solve this problem, some people put forward the slogan of "de-coalification. From the perspective of the long-term development of human access to energy, "de-coal" is a process that is taking place, but we should be soberly aware that "de-coal" will not affect the "boss" status of coal in China's energy consumption in the short term.
Since 2017, a large-scale "coal to gas" operation throughout North China has encountered bottlenecks due to the shortage of natural gas. With the existing natural gas import, transportation and processing capacity and its system, it is difficult to meet the grim reality of China's demand for natural gas. This has caused structural, temporal, and regional contradictions in the supply and demand of natural gas in some areas, affecting the winter heating of some people and the industrial production of some enterprises.
Practice has proved that the implementation of coal reduction and clean utilization strategy, under the premise of meeting the safety emission standards, efficient and clean utilization of coal, is a more environmental and cost-effective coal utilization strategy.
Japan's coal consumption has continued to grow since the oil crisis in the 1970 s, especially after the Fukushima nuclear accident, in order to make up for the energy shortage caused by nuclear abandonment, coal consumption began to enter a new round of rapid growth. Solving the contradiction between the utilization of coal resources and the realization of emission reduction targets has become a major issue facing Japan's economic development. To this end, Japan has incorporated the environmental protection policy of coal utilization into the overall environmental protection policy system for management.TechnologyImplement dynamic control.
According to the "21st Century Coal Technology Strategy" issued in 1999, Japan will realize the recycling of coal resources and achieve zero emissions from coal utilization by 2030, and has formulated a three-stage technology research and development and promotion strategy. In Japan, the main technical barriers to the use of coal as a clean energy source no longer exist. Japan's experience shows that the country's increased investment in research and development of clean and efficient coal utilization technology is an important driving force to promote the development of clean coal technology.
Combined with the development trend of clean coal in the world and China's national conditions, we should focus on research and development and promotion of efficient clean coal-fired power generation, efficient clean coal-fired industrial boilers, clean industrial fuel gas preparation technology, moderate development.new typeCoal chemical technology. The "Energy Production and Consumption Revolution Strategy (2016-2030)" and the "Thirteenth Five-Year Plan for Energy Development" formulated by the National Energy Administration include near-zero carbon emission demonstration actions and coal clean utilization actions.
Thanks to advanced technologies such as coal chemical industry and flue gas purification, the latest thermal power plants have been able to solve the problems of clean utilization of coal and ultra-low emission of pollutants. In Shandong Province, a new type of clean and efficient coal utilization technology is being widely used, especially in the two fields of urban central heating and industrial park cogeneration, coal-water slurry technology has made rapid development.
At present, China already has the world's more stringent emission standards for coal-fired power generation pollutants. In the future, more stringent and complete environmental protection and energy-saving regulations and standards can be formulated to promote the promotion of clean and efficient coal utilization technologies. We must strictly implement the control objectives and standards of coal pollutant emissions, control the total amount of coal consumption through carbon emission trading mechanism and other means, so as to realize the reduction of coal production; at the same time, we should formulate the national development strategy and technological innovation roadmap of clean coal utilization and efficient power generation as soon as possible, and earnestly strengthen the construction of demonstration projects and the promotion of clean coal technology, So as to realize the clean and efficient utilization of coal.
