On October 18, Zhou Yuxian, Secretary of the Party Committee and Chairman of China National Building Materials Group, attended the second special working meeting and the working meeting of the Building Materials Carbon Committee held by the China Building Materials Federation in Beijing. The special topic reviewed the research results of the topic "Major Policies of the Source Prevention and Control System of the "Two Highs" Project Management in the Building Materials Industry (Cement and Flat Glass)".
Yan Xiaofeng, Secretary of the Party Committee of China Building Materials Federation, presided over the meeting and made a speech, Executive Vice President, Secretary of the Party Committee and Chairman of Beijing Jinyu Group Co., Ltd., Zeng Jin, Executive Vice President, Former Party Secretary and Chairman of Anhui Conch Group Co., Ltd., Gao Dengbang, Executive Vice President, Secretary of the Party Committee and Chairman of Jinjing (Group) Co., Ltd., Wang Gang, Executive Vice President, Secretary of the Party Committee and President of Huaxin Cement Co., Ltd., Li Yeqing, Resident Leaders Chen Guoqing, Zhang Dongzhuang, Zhang Guangpei, Liu Jianhua, He Jun, Shang Yanqing and Sun Xingshou attended the meeting and listened to briefings on the setting of indicators for the "two highs" project in the cement and flat glass industries and relevant policy suggestions. The leaders attending the meeting carefully deliberated and discussed the research results and put forward suggestions for revision and improvement.
The meeting unanimously agreed that the whole industry must thoroughly implement the major decisions and deployments of the Party Central Committee on unswervingly taking the road of green and low-carbon development, curbing the blind development of the "two highs" projects, and implementing the synergistic effects of pollution reduction and carbon reduction. In the face of the current tight supply and demand situation of coal and electricity supply and demand, we must correctly understand and grasp the changing trend of energy supply and demand, take the carbon peak goal and the carbon neutrality vision as the traction, further strengthen the awareness of energy conservation, continuously dig deep into the potential of energy conservation, accelerate the adjustment of the energy-using structure based on coal, enhance the industry's energy supply guarantee capabilities, carry out industry self-discipline in accordance with laws and regulations, maintain market order, effectively fulfill the corporate social responsibility of the industry, and make their own contributions and efforts to achieve the "double carbon" goal and safe and high-quality development of the building materials industry.
China National Building Materials Group Green Low Carbon Practice PRACTICE
01 Collaborative disposal of cement kilns
36 cement collaborative disposal production lines have been built, with an annual treatment of 3.59 million tons of solid waste and domestic waste, and 900 mu of landfill land.
Sinoma Anhui Cement Kiln harmlessly coordinated disposal chaohu city 500t/d domestic garbage project daily treatment of about 500 tons of garbage, the annual disposal of chaohu city about 182,500 tons of domestic garbage, can save 22,800 tons of raw coal, save about 10,000 tons of raw materials, carbon emission reduction of 70,000 tons, save 30 acres of landfill land per year (calculated according to the height of the pile 10 meters).
02 Waste heat for power generation
293 sets of waste heat power generation in the cement sector were built, with an installed capacity of 2197.3 MW, and the waste heat power generation capacity in the first half of 2021 was 4.318 billion kWh, saving 530,000 tons of standard coal and reducing CO emissions by 1.39 million tons。 The total installed capacity of waste heat power generation in the glass plate was 318.5 MW, generating 1.9 billion kWh of electricity throughout the year, saving 237,000 tons of standard coal and reducing CO emissions by 631,000 tons。
Changxing South built a 15 MW waste heat power generation system, with an annual power generation capacity of 103 million kWh, saving 12,300 tons of standard coal and reducing CO emissions by 100,000 tons。
Anhui Chaohu Cement Collaborative Disposal Of Domestic Waste Project, supporting a 27 MW waste heat power generation system, generates 170 million kWh of electricity per year at a 7% self-consumption rate, saves 68,700 tons of standard coal per year, reduces ANNUAL CO emissions by 144,000 tons, SO emissions by 143 tons, and NOx emissions by 505 tons。
Henan Shangqiu's Zhonglian Glass Float Glass Production Line was delisted and entered the park with an installed capacity of 4.5 MW of waste heat power generation project, which was connected to the grid in September 2020, and the project can reach an annual power generation capacity of 31.37 million kWh, saving 9,412 tons of standard coal and reducing CO emissions by 24,659 tons.
The 2 MW NFGIL-600t/d glass kiln waste heat power generation project in Dhaka, the capital of Bangladesh, was connected to the grid in July 2021, and the project can achieve an annual power generation capacity of 13.44 million kWh, save 4,033 tons of standard coal, and reduce CO emissions by 10,568 tons.
03 All-oxygen combustion technology
Five all-oxygen combustion glass production lines were built, with a total daily melting capacity of 1,300 tons, an annual saving of 24,400 tons of standard coal, and a CO emission reduction of 64,800 tons.
Compared with the traditional air combustion kiln, the all-oxygen combustion ultra-white glass production line of China National Building Materials (Hefei) New Energy Co., Ltd. has increased the melting rate by more than 10%, the nitrogen oxide emission reduction has exceeded 70%, saving about 5195 tons of standard coal per year, and the kiln age can be increased to more than 8 years.
04 Photovoltaic power generation projects
99 photovoltaic power generation projects have been completed, with an installed capacity of 1450.39 MW, an annual power generation capacity of 1.592 billion kWh, and an annual reduction of CO?5876 million tons, which is equivalent to reducing the consumption of standard coal by 636,800 tons。 Among them, there are 41 photovoltaic building integration projects.
