"2025 China Cement Double Carbon Conference and the 13th Energy Conservation and Environmental Protection Technology Exchange Conference" continues brilliantly

On May 28, the "2025 China Cement Double Carbon Conference and the 13th Energy Conservation and Environmental Protection Technology Exchange Conference" continued. Lu Guixin, former first-level inspector of the Department of Raw Materials Industry of

the Ministry of Industry and Information Technology, Wang Fazhou, Standing Committee and Vice President of the Party Committee of Wuhan University of Technology, Ma Weiping, Chairman of OCC, Wei Huashan, Chairman of Queshi Cement Group Co., Ltd., and Wang Xuejun, Executive Chairman of Hubei Cement Industry Association. Wang Lei, President of North Cement Co., Ltd., Xu Li, Vice General Manager of Tangshan Jidong Cement Co., Ltd., Chen Zhongsheng, Vice President of Shandong Shanshui Cement Group Co., Ltd., Zhu Gang, Deputy Engineer of Tianshan Material Co., Ltd. Xu Yue, Assistant General Manager of Anhui Conch Cement Co., Ltd.

For challenges, how can cement enterprises convert carbon quotas into carbon assets and realize their value-added? Ccement. Com/Price _ list -1-s0-e0-p0-c0-k100059-b0. Second, optimize the carbon market trading strategy: analyze the trend of carbon price fluctuations (such as demand surge before the performance period), buy low and sell high, actively participate in the voluntary carbon market, CCER replacement and other gains. 3. Strengthen the management of carbon assets: establish a carbon asset management information system to accurately grasp the carbon emissions of the enterprise itself and its products, check the composition of carbon emissions and timely identify and solve potential problems through the recording and analysis of carbon emission data, so as to improve the management level of carbon assets and reduce the cost of performance.

Lei Qi said that in addition to energy-saving and emission reduction technologies, deep emission reduction measures such as raw material substitution and fuel substitution also need to play an important role; non-carbonate alternative raw materials and alternative fuels can be deducted from the accounting boundary of clinker production in the carbon market; Lei Qi also pointed out that cement burning has large carbon emissions, CCUS technology is regarded as the key technology to achieve carbon neutrality in the cement industry, is the necessary choice to achieve carbon neutrality in the cement industry, and is also the object of urgent development.

Pi Yubiao pointed out that to a certain extent, the disposal of idle waste assets in cement enterprises is not transparent, the procedures are not standardized, the bidding is inadequate, the disposal price is low, the idle materials in stock can not effectively realize the exchange of resources, and some enterprises do not have their own exclusive platform.

Jupai is positioned as a B2B platform for online trading of renewable resources, with the mission of "making waste business easier", providing full-link digital disposal solutions to large enterprises. Specific services include asset disposal, whole plant demolition, production line demolition, material circulation, platform construction, entry transactions, etc.

Shen Weiguo stressed that The choice of emission reduction technology for enterprises should be based on their own reality. Due to the differences in resource endowment, equipment level and technology base, the priority order of emission reduction strategies for enterprises is as follows: the first choice is to use calcium alternative raw material technology to reduce carbon emissions from the source; the second is to consider alternative fuel technology to balance emission reduction and cost; and the last is to use energy-saving and fuel-saving technology to improve comprehensive benefits.

At the same time, the key to sustainable development is the technology that can reduce costs, increase efficiency and protect the environment, and make full use of local bulk solid waste. The "policy-oriented" technology relying solely on government subsidies may only be a "face-saving project" to create a green image in the long run, and will eventually be eliminated by the market due to the lack of endogenous motivation.

Zhong Yonghui also shared the precautions for the operation and maintenance of the waste heat boiler: 1. The coordination between the waste heat boiler and the cement kiln and the avoidance of running raw materials as far as possible; 2. The avoidance of sudden cooling and sudden stop as far as possible; 3. The water quality of the waste heat boiler is tested to meet the requirements of the standard-GB/T 12145; 4. Pay attention to regular and continuous blowdown to prevent steam and water from rising together; 5. Sampling and analysis of steam and water-to provide theoretical support for water treatment, blowdown and dosing; 6. Regular inspection of the waste heat boiler-to find problems in time to avoid the expansion of the impact; 7. Eliminate boiler dry firing-AQC boiler and ASH common superheater; 8. Prepare corresponding emergency measures-boiler full of water, water shortage, leakage, etc.; 9. Boiler long time shutdown protection-wet protection, dry protection.

2025, the Ministry of Ecology and Environment issued the Work Program of the National Carbon Emission Trading Market Covering Steel, Cement and Aluminum Smelting Industries, marking the first expansion of the national carbon emission trading market into the operational implementation stage. Liu Liang believes that achieving the goal of "double carbon" requires joint efforts in many fields, and the carbon market is one of the important tools.

Liu Liang also shared the first case of national carbon market performance, the first case of carbon emission quota trading, the first case of carbon emission trading disputes in Shandong Province and other carbon market risk control and litigation cases.

on cement grinding. 1. "Treatment before grinding is the key": the pre-grinding equipment before grinding should always maintain a stable and efficient extrusion work state to lay a solid foundation for the grinding and shaping of the tube mill; 2. "Grinding in the mill is fundamental": optimize the internal structure of the tube mill and give full play to the technical advantages of the dynamic grinding body in the mill in grinding and shaping of cement particles; 3. "Powder selection after grinding is the guarantee": the selection and application of high-efficiency finished product powder concentrator and high-efficiency energy-saving fan provide a strong guarantee for the efficient classification of grinding materials in the system.

It is estimated that the current carbon emission intensity per ton of cement in China is lower than 600kgCO2/t, with a slight rebound in 2024 (the new national standard increases the clinker coefficient). Globally, China is at a relatively low level, the European Union and Germany are at a low level (high fuel substitution rate, low-carbon electricity, carbon policy mandatory), and Indonesia and Vietnam are at a high level (coal-dominated, high clinker coefficient, high energy consumption of equipment, etc.).

Li Kunming said that in 2060, the demand for cement will be 500-600 million tons, the output of clinker will be about 400 million tons, and the total carbon emissions will be reduced by more than 66% (without considering other circumstances, only under the condition of declining production). From the comparison of ways to reduce carbon emission intensity, alternative fuels and CCUS have great potential, but the application status of CCUS technology is still in the research and development stage, and the economy is poor.
