Shandong Commercial Daily / >
in this year's national two meetings, the CPPCC National Committee, deputy director of the Committee for population and Environment Commission, Qin Dahe, academician of the Chinese Academy of Sciences It is pointed out that bulk coal and unclean coal are the main causes of fog and haze in China. In this series of reports on coal burning disease last year, the newspaper gave clear data in an experimental way. The pollution caused by the scattered coal has aroused the attention of the whole society. In the two period (2016-2017 year) action plan for the prevention and control of air pollution in Shandong province (2016-2017 years) action plan (Draft for comments) published yesterday, it was proposed that the 17 cities of Shandong should say no to the scattered coal, in which the provincial capital city group banned the sale of coal in 2017 and fired the coal, while the cities and suburban areas of the other cities and cities should also say goodbye to the coal.

burning powder coal is the main cause of fog haze
Qin Da River in the national two meetings in front of the day, the haze is mainly caused by human activity emissions, many sources of emissions, coal is the most important in the country. Yes. "As far as I know, by 2050, the proportion of coal as an energy source in China will be more than 50%. So under the current circumstances, bulk coal and clean coal are the main causes of haze or fog and haze in China's cities.
from this passage, it is easy to see that his view is to increase the transformation of traditional coal-fired boilers, clean coal resources and eliminate scattered coal at the same time.
reporters understand that the proportion of coal in Shandong's energy structure is nearly 80%, and the completion rate of the ultra-low emission of coal-fired units (boilers) is only 18.7%. The amount of coal used in the province is about 4 million tons. According to the monitoring results of the environmental protection department, the concentration of pollutants discharged from bulk coal is dozens of times that of the power plant. Through experiments, the reporter found that the sulfur dioxide and other pollutants produced by a ton of coal are 23.5 times as high as the quality coal used in the heating enterprises and produced by the treatment of sulfur dioxide after treatment. The emission of pollutants in a heating season is as much as 5 times as much as that of a heating season in the whole of Ji'nan. "Although the heating coal is only about thirty million tons, the total amount of pollutants discharged may exceed 360 million tons of coal-fired emission that accounts for more than 90%." Zhang Bo, director of the provincial environmental protection department, said that. The
provincial capital city group will disable the coal for heating
in the two phase action plan of the air pollution prevention and control plan in our province, to promote the clean and efficient utilization of coal. By the end of 2016, coal consumption had decreased by 10 million tons compared with 2012, and by the end of 2017, it would be reduced by about 10 million tons.
at the same time, it will further promote the comprehensive treatment of coal fired combustion. It includes issuing the quality standard of bulk coal supply, vigorously promoting the application of environment-friendly stoves, and gradually expanding the scope of prohibition of burning high polluting fuels. By 2017, the built-up area, the urban and rural joints, and the provincial capital cities group will not sell or use the scattered coal.
comprehensive treatment of industrial pollution, the implementation of ultra low emission transformation of coal-fired units (boilers) has been fully implemented. By the end of 2016, 300 thousand KW and above coal-fired units completed the ultra low emission transformation reached 70%, and the single machine 100 thousand kilowatt to 300 thousand kilowatts of coal-fired units with ultra-low emissions reached 50%. Before the end of 2016, the single machine, 100 thousand KW and more coal fired units were completely reformed.
power and natural gas heating will replace "earth heating"
loose coal will gradually be eliminated. How to solve the heating problem of many residents in winter? According to the two phase of action plan, our province will actively develop cogeneration and carry out central heating. The existing decentralized heating boilers and small heat supply units should be integrated to build a large-scale cogeneration unit. By the end of 2017, all cities, counties and industrial parks basically realized central heating, and the central heating penetration rate reached over 70%. Not in a large heat pipe network coverage, each industrial park only maintains a coal-fired heat source. In other areas where heating and gas supply networks are not covered, briquette or clean coal should be used instead. Comprehensive elimination of dispersed coal-fired boilers.
in addition, clean energy will be used instead of coal. Our province will actively promote "external power into the Lu", and strive to reach the end of 2017, the "foreign power into the Lu" call increased to 24 million kilowatts. At the same time, we should increase the supply and utilization of natural gas, coal to natural gas and coal-bed methane, and give priority to protecting residents' gas consumption and heating in winter. Actively coordinate the central oil enterprises to increase the supply of natural gas in our province and speed up the construction of the LNG project in Qingdao. By the end of 2017, the natural gas supply capacity of the province is striving to reach 20 billion cubic meters.
