Recently, the National Development and Reform Commission, the Ministry of Ecology and Environment and the Beijing Municipal Government jointly held the 2018launching ceremony of "National Low Carbon Day of National Energy Conservation Publicity Week and Beijing Energy Conservation Publicity Week Low Carbon Day" in Beijing.Ning Jizhe, deputy director of the National Development and Reform Commission, said in his speech that my country's energy conservation work has implemented the decision-making and deployment of "double control" of total energy consumption and intensity, and has achieved remarkable results.From 2013 to 2017 , China's energy consumption per 10,000 yuan of GDP decreased by 20.9% , saving 10.3100 million tons of standard coal. Last year, the country's total energy consumption was 44.9100 million tons, and the average annual energy consumption growth rate of 2.2% supported the average annual GDP growth rate. 7.1% growth.
"Energy saving and energy efficiency should be taken as the source measure to fight the tough battle of pollution prevention and control and win the battle to defend the blue sky." Ning Jizhe pointed out that, specifically, it is necessary to optimize the energy structure, increase the efforts to reduce coal consumption and replace it, and promote the Beijing-Tianjin-Hebei and surrounding areas, the Yangtze River Delta, the Pearl River Delta and other key regions have completed the goal of reducing and replacing coal consumption.At the same time, it is necessary to cultivate and expand energy-saving and environmental protection industries, cleaner production industries, and clean energy industries, and comprehensively promote energy-saving transformation and cleaner production transformation in traditional high-energy-consuming industries.In addition, it is necessary to carry out in-depth energy conservation actions for all people, comprehensively promote energy conservation in key areas such as industry, construction, transportation, public institutions, and residential energy consumption, and continuously improve the awareness of energy conservation in the whole society.
According to the "Analysis Report on the Development Prospects and Investment Strategic Planning of China's Industrial Energy Conservation Industry" by the Qianzhan Industry Research Institute, the industrial energy efficiency management market can generally be divided into /three sub-sectors: the industrial energy conservation product technology market, the industrial energy conservation service market, and the contract energy management market.
In response to the transformation of the energy structure, many experts believe that coal reduction is a prerequisite for clean and efficient utilization. Otherwise, no matter how low the pollutant emission concentration is, the total amount will still be huge.It is reported that from the trend, coal reduction and clean energy replacement are steadily advancing. In the past two years, China's coal production capacity has exceeded 100 million tons. Last year, non-fossil energy accounted for 5of the country's total energy production , an increase 17.6% 2012year .6.4of a percentage point year-on-
It is understood that Beijing has been quite effective in reducing coal consumption. The relevant person in charge of the Beijing Municipal Environmental Protection Bureau said that in the past five years, 99.8% of the coal-fired boilers in Beijing have been eliminated, correspondingly reducing coal burning by nearly 90010,000 tons.In addition, in order to promote the deep emission reduction of nitrogen oxides in boilers, Beijing took the lead in carrying out low-nitrogen transformation of gas-fired boilers in the country, mainly by replacing low-nitrogen burners or low-nitrogen gas boilers to control the source of nitrogen oxides.As of the 11middle of last year, Beijing had phased out a total of coal-fired boilers 4453and a 13259ton of steam, and completed the low-nitrogen transformation of gas-fired boilers of about 1 7000and a 23000ton of steam.
According to incomplete statistics, there are 48nearly 10,000 coal-fired heating industrial boilers and about 1310,000 kilns in China, with an annual coal consumption of about 7.5100 million tons.Zhang Shaoqiang, chairman of the China Coal Processing and Utilization Association, introduced that the boiler efficiency is low and the pollutant control facilities are simple. A large number of heating boilers have large load changes due to seasonal factors. The actual combustion efficiency and boiler thermal efficiency are on average 15%-20% lower than the international advanced level. , resulting in smoke emissions exceeding 40% of the national total emissions, sulfur dioxide emissions accounting for more than 35% of the national total emissions , becoming a serious source of air pollutant emissions.
"The total consumption of bulk coal for civil use is 2about 100 million tons per year. Most of the stoves are primitive, scattered in use, and the user's economic bearing capacity is not high. It is a hard 'hard bone' for the clean and efficient utilization of coal. "Relevant person in charge of the National Energy Administration Said that China will adhere to the combination of bulk coal reduction and clean substitution, and the combination of dredging and blocking, through the implementation of high-quality coal sources, the construction of clean coal distribution centers, the promotion and application of clean coal and briquette coal, advanced civilian stoves, and strengthening supervision and other measures. Solve the problem of clean utilization of loose coal for civil use.
