China Resources Dengfeng Power Plant
'The indicator to be completed in the first five years will now be completed in a year and a half. If it is not completed, it will be restricted and severely restricted by the region, seriously affecting the future development of Henan.' Turning to the issue of air pollution control, the government of Henan Province Commissioners, Politics and Law Committee Xu Kanlu said so.
Beijing-Tianjin-Hebei air pollution transmission channel '2 +26' city, Henan Province, occupy 7 seats, the number ranked second; due to poor air pollution control by the Ministry of Environmental Protection listed the first supervisor, many interviews with the city of Anyang also Henan; In addition, Henan is still a key area for coal production capacity and a large emerging industrial province in the Midwest ......
Under the heavy pressure, the Central Plains of the soil pollution control battle is not good to fight into the most critical heating season, our reporter recently went to Henan, more than ground visits to tackling pollution problems and clean heating progress.
Night strong winds, the next day in Zhengzhou, Henan Tianlang Qi Qing. Living in Zhengzhou Hi-tech Zone Shengshi Harbor Area Kang Uncle happy not to wind up: the wind blew away the pollutants, the air quality is better, but the temperature has also followed a decline, district concentration What time heating can pass?
Clean heating related to people's livelihood, related to the effectiveness of air pollution control.
In the heating season, pollutant indicators coupled with unfavorable conditions such as the steady weather, prone to pollution rebound, some work may have come to naught. More than a month ago, Henan Provincial Committee, Politics and Law Committee Xu Ganlu emergency presided over the province Air Pollution Control Sprint 30 days to build a meeting: 'Tonight's meeting emergency can not be dragged to tomorrow, because the time is too tight, could not sit still, sleep could not sleep!'
Control pollution, reduce emissions and ensure people warm through the winter - 2017-2018 heating season, gas coal, electricity coal, clean coal 'three alternative' has become a key task of Henan.
Electric double replacement
Heating season PM2.5 concentration down 3 percent
Henan Province, director of the Office of the Environmental Pollution Prevention and Tough Battalion Office of the Director of Provincial Environmental Protection Department Li Heping remember clearly that January 7, 2017, the New Year's first high-profile large-scale, sinking to the county level, thousands of people to participate in is the environment Pollution Prevention and Tackling mobilization and deployment meeting. 'Environmental Governance' was listed as one of the provincial 'four major battle', 'accelerate the winter clean heating' included in the ten key livelihood facts. It is precisely because of this, Quickly caused the concern of relevant departments.
To this end, Zhengzhou set up a special coordination group to investigate the delay in heating, because developers slow construction, heating equipment is not in place, the group not only to help solve the financial problems, but also personally organize and supervise the construction of the original 50-day project , Hurriedly completed before the New Year's Day. Through CHP, residents expect more than two years of central heating was finally opened, the average home temperature of up to 23 degrees Celsius, 'do not have to open the air conditioning, can save a lot of electricity!
Zhengzhou City, Zhongmu County, Anyang City, Huang County and other places last year, there have been varying degrees of heating interruption, the main reason is the shortage of natural gas .Hunan Provincial Development and Reform Commission said frankly that for the sprint pollution control battle, the original 2- In the past three years, the task of "replacing coal with gas" was completed in just one year, and the multi-factor led to the rapid growth of gas consumption in the entire province. Only the growth rate in January-November last year was nearly 10 percentage points higher than the national average.
However, instead of waiting, we actively took measures to ensure the peak winter. "The official said that in addition to actively communicating with the upstream gas supply enterprises and implementing the gas source, they coordinated the supply according to the principle of" pressing non-residents and entering the heating season , Has also shut down the gas plant in Zhengzhou, reducing the number of gas companies such as aluminum gas indicators to ensure that civil unaffected.
It is understood that, combined with the current situation of 'Rich Electricity and Less Gas', according to local conditions, Henan completed a total of 1.13 million residents of double replacement last year, surpassing the annual mission of 1 million households, of which about 90% While heating more than 5 million residents, it can reduce the consumption of coal by 2.05 million tons, and the proportion of coal consumption in Henan as a percentage of total energy consumption drops below 75%. From the beginning of the heating season last year to the end of the year, the average concentration of PM2.5 in the province dropped by 31.5%.
Clean coal instead
Realize supply and demand both sides clean and reform
Central heating is the livelihood of the people and the blue sky and white clouds are also related to happy life.Henan still has more than 8.5 million scattered coal users, with an annual consumption of over 8.25 million tons, of which over 80% are rural users and the total amount of domestic bulk coal exceeds one year 7.1 million tons, becoming one of the main sources of air pollution.How to clean the heating for these temporarily do not have the conditions of central heating or double replacement?
Li Heping introduced that in order to win the public's warmth and clean air's' win-win 'situation, Henan fully used low-sulfur clean coal instead of loose coal and prohibited inferior coal from entering the market to minimize the impact of loose coal on the environment.' There are 217 clean coal production and warehousing supply centers and 1568 distribution outlets, closing or renovating 2316 existing sales outlets for civilian bulk coal.
Used to be briquette, it is now 'small briquettes', expensive expensive new coal? Warm home? Burned it easy?
Take the first attempt to clean alternative coal Anyang City, for example, 'we used to burn the briquettes, suddenly replaced, both afraid of not afraid of not warm, and some do not even know how to burn.' Anyang City Development and Reform Commission Energy Office relevant responsible person. As early as the promotion of early, Anyang on the organization of personnel training, hands-on church people use. 'And as warm as the original!' Anyang Niu Fang community, resident Zhang Baoguo repeatedly said.
It is estimated that the price of clean coal about 1200 yuan / ton, the cost of using traditional coal is about 2 times.In order to eliminate residents concerns, Anyang has also implemented a series of subsidies.
'How do we pull away the residents scattered coal, how to pull clean briquette!' The official said, who use clean briquette users, must be turned over to the original stove, equipment subsidy of 1,000 yuan per household , Equivalent to a free upgrade stove .According to a heating season 2.5 tons of coal per household calculation, will also subsidize 400 yuan per ton.At present, nearly 40% of Anyang households use clean coal heating, the city's unified network of 1157 outlets to provide sales , Delivery, registration and other services.
It is worth mentioning that, with the promotion of clean briquette, coal production in Anyang has also been upgraded.The city has banned nearly 1000 small factories that do not meet the environmental requirements, leaving only 16 environmentally friendly clean coal production companies. 'We Recent briquette has been transformed, can be targeted for the production of clean briquette for the user to choose, so closer to the original people's habits. 'The above official said.
Ultra-low emissions reform
Coal is as clean as natural gas
As a province of coal consumption, coal-fired power plants have also been one of the sources of air pollution in Henan Province.In order to make the production cleaner and more efficient, a number of power companies take the initiative to implement ultra-low emissions, the province shipped 144 units of 57.19 million kilowatts Coal generating units and 1,080,000 kilowatts of 104 local coal-fired generating units, have now been fully completed ultra-low emissions.
In Henan, the first completed transformation of China Resources Power Dengfeng Co., Ltd. (hereinafter referred to as 'China Resources Dengfeng'), stood at the entrance of a piece of electronic screen was particularly prominent. Real-time display of various environmental data on the screen, each unit of nitrogen oxides , Sulfur dioxide, dust and other emission indicators at a glance, as well as ultra-low emission standards for reference.
'Our 12 coal-fired generating units have all been ultra-low-emission retrofitted and now coal is as clean as natural gas!' Liang Wen-ya, general manager of CRBC, introduced that after the retrofits, it will reduce annual emissions of nitrogen oxides under the same conditions About 1240 tons, reducing the proportion of 55%; reduce emissions of about 1900 tons of sulfur dioxide, reducing the proportion of 72%; reduce emissions of about 610 tons of soot, reducing the proportion of 91%. 'Now the night can clearly see the stars, a few years ago Very rare!
Located in Xinmi City, Henan's third largest thermal power plant in Zhengzhou Yuzhong Energy Co., Ltd., power generation, heating coal has been replaced by local low-sulfur lean coal to achieve ultra-low-emission reform at the same time, the plant also take the initiative to lead the industrial steam into the industry Park, replacing the original park more than 50 sets of 200 steam tons of small boilers until the end of last year, accumulative total of nearly 420,000 tons of steam, to contribute to energy saving.
According to the State Grid Henan Provincial Power Company statistics, as of November last year, the provincial coal-fired power plant unit Sulfur Dioxide, dust decreased by more than 60% over the same period, the average emission concentration less than half of the national standard.Nitrogen oxides down 3% , The average concentration of 73% of the national standard.
The reporter learned from the interview that the average concentration of PM10 dropped by 23.9% and the average concentration of PM2.5 decreased by 31.5% year-on-year in the heating season until the end of the year from November 15, 2017. The number of good days increased by 14 days as compared with the same period in 2016, The number of pollution days decreased by 6 days as compared with the same period of last year, of which, the improvement rates of PM10 and PM2.5 ranked the forefront among Beijing, Tianjin and surrounding cities of 2 + 26.
