After years of efforts, the overall governance of Beijing's total coal consumption has achieved initial results. By the end of 2017, all of the total coal consumption of 4.85 million tons, accounting for only 5.6% of the city's total coal consumption, coal-fired completed three years ahead of "Thirteen Five" energy development plan period proposed control in less than five million tons The goal.
By 2013 to 2017 for five consecutive years to promote the work Yajian coal, Beijing successfully completed the first phase of the "Yajian based" Yajian coal work, go to "run mainly to protect", established clean energy use long-term mechanism to combat second phase coal-fired rebound. Beijing's total coal consumption in the future will be long-term control in less than 4.2 million tons, coal is mainly used for urban hazardous waste incineration, energy and protect the city safe operation of remote mountain villages Beijing winter heating three aspects.
As of last heating season, heating central heating proportion of clean energy in Beijing has reached 98%, in addition to parts of Pinggu and Yanqing, Miyun three zones as well as six coal-fired heating boiler room, other regions have achieved heating boilers no Coal.
This year, Beijing will complete the rural village 450 villages, the villagers coal public spaces and 53,000 square meters of agricultural facilities Zizhong change clean energy work, and strive to complete the Yanqing east of central heating central heating fuel in pre-season coal boiler clean energy transformation, in an orderly coal-fired heating center south of Yanqing, Pinggu Riverside, Xinggu, Miyun Taishi Tuen urban and non-built-up areas boiler clean energy transformation.
In addition, this year, Beijing Yanshan Petrochemical Industries will start coal-fired facilities clean energy transformation, and continue to consolidate six districts of the city, the southern plains "No Coal" results have been achieved on the area of clean energy transformation, embargo, ban, ban save bulk coal, to prevent rebound.
Speed up the construction of clean energy facilities, Beijing will work to enhance the rural town of Plains gas pipeline network construction, improve rural consumption of clean energy supply security capacity, promote Plains natural gas pipeline "through town." In the gas network facilities are relatively weak areas, speed up the liquefied natural gas, compressed natural gas supply facilities, increase the supply capacity of natural gas distribution in rural areas. At the same time, we continue to promote the 2018 "from coal to gas," "coal to electricity" supporting gas engineering and construction of power transmission project, to meet the full 2018-- coal to clean energy by 2019 energy demand for the heating season.
Our case with 10-ton coal industral boiler sarawak. Operating costs 10 tons of coal-fired boilers coal 600 yuan / ton, compared with 0.6 yuan / kg; calorific value 5500 kcal / kg; required heat 6 million kcal / hour and 10 ton boiler; coal boiler thermal efficiency 70-80 % (75% in accordance with our calculated): 10 tons of coal fired boiler 1 hour the desired amount: 6000000kcal / h ÷ 5500kcal ÷ 75% = 1455kg / h; 10 tons of coal boiler 1 hour investment costs: 1455 × 0.6 = about 873 yuan. 10 tons of gas boiler running costs of piped natural gas price of about 2.8 yuan / Nm3; calorific value of 8600 kcal / Nm3; thermal efficiency between 90% -95% (we calculated 90%); caloric needs 6 million is 10 ton boiler cards / hour, i.e. 77.52Nm3 / h; 10 tons of gas required for the gas boiler 1 hour: 6000000kcal / h ÷ 8600kcal ÷ 90% = 775.2Nm3 / h; 10 tons of gas boiler 1 hour run investment costs: 2.8 yuan / Nm3 × 775Nm3 / h = 2170 dollars.
Recently many of my friends to consult some "coal to gas" issue, the cost is certainly more expensive than coal-fired coal industral boiler sarawaks, but specifically how much more expensive? The count this account of how the enterprise? We've put together some information for your reference.
