Beijing actively organizes technical forces, carries out technical research and development, demonstration and other scientific and technological support work in energy conservation, emission reduction and consumption reduction, and has achieved a number of innovative scientific and technological achievements, and the energy saving effect is remarkable. At present, the Beijing Municipal Science and Technology Commission is working with relevant departments to jointly develop an application plan for the promotion of results. Through the appropriate promotion of these scientific and technological achievements in Beijing, the total annual savings of 2.3 million tons of standard coal, reducing the city's total energy consumption by about 4%.
1. Research and demonstration of key technologies for energy saving in large public buildings
R & D real-time statistics, analysis, release and quota management system for large-scale public buildings, so that the energy consumption of new large-scale public buildings will be reduced to 50% on average, and the energy consumption of large-scale public buildings will be reduced by 30%. It is planned to complete the 36 million square meters public construction renovation target within the “Eleventh Five-Year Planâ€. After the renovation, it can save 450,000 tons of standard coal and reduce sulfur dioxide emissions by 9,200 tons.
2. High-efficiency, energy-saving, low-pollution natural gas boiler system research and development and industrialization
This technology can increase the thermal efficiency of conventional natural gas boilers from the current 88% to over 98%. The boiler body structure can reduce steel consumption by about 30%, boiler cost by about 20%, and nitrogen oxide emissions by 75%. It can save 300 million cubic meters of natural gas per year (equivalent to saving 370,000 tons of standard coal) and direct economic benefits of nearly 900 million yuan, which can reduce carbon dioxide emissions by 580,000 tons and nitrogen oxide emissions by 6,000 kilograms.
3. Research and demonstration of key technologies for residual heat and pressure generation in Liulihe Cement Plant
This work can achieve high-efficiency recovery of low-temperature flue gas in the cement industry. It can achieve the national energy-saving index for the cement industry ten years ahead of schedule, saving 150,000 tons of standard coal per year, reducing pollution emissions by about 44,000 tons of carbon dioxide and 300 tons of sulfur dioxide. , 65 tons of nitrogen oxides, and achieve annual water saving of 400,000 tons, annual reduction of dust emissions of about 140,000 tons.
4. Research and demonstration of waste heat reuse in power plants
Through research and research to solve the low-temperature circulating water heating technology, the low-grade heat source of the circulating cooling water that cannot be utilized is transformed into a heating heat source for centralized heating in the surrounding area. The city's promotion and utilization can reduce 600,000 tons of standard coal consumption per year, save 3 million tons of water per year, and reduce pollution emissions: SO213200 tons, nitrogen oxides 4020 tons, and soot emissions 5040 tons.
