"2023 China Cement Energy Conservation and New Energy Development Conference" continues to be wonderful!

On July 7, the "2023 China Cement Energy Conservation and New Energy Development Conference" sponsored by China Cement Network continued to be held in Chongqing, a mountain city. The next day's meeting was still full of dry goods and wonderful! Ccement. Com/richtext/IMG/tbhz8vuu0er1688710544905.jpg ">

The theme of this conference is" energy saving and cost reduction, green energy helps to improve quality and efficiency ". Bo Kegang, Party Secretary and President of Southwest Cement Co., Ltd.; Cui Cheng, Researcher of Macroeconomic Research Institute of National Development and Reform Commission; Zhang Zhenkun, President of China Cement Network and CEO of Asia Cement (China) Holding Company; Lv Zhijian, President of Xinjiang Building Materials Industry Association; Xiong Ke, Secretary-General of Chongqing Cement Association; Chairman Unit of China Cement Network, Eastern Hope "). Zhong Gen suggests to solve the problem in the following ways: first, reduce the weight of the five-to-six local cyclone: for example, C1 cylinder without refractory material or ultra-thin refractory material; second, deeply optimize the firing system (five-stage preheater) and the calciner body: personalized scheme, one factory, one policy; The third is "five plus" (or 5.

emissions, ranking third in the country.

Zhang Shuangqing shared in detail the application of distributed photovoltaic power generation and energy storage technology. He pointed out that distributed photovoltaic is the preferred new energy investment field in the cement industry, and distributed photovoltaic power plant CCER development. With the continuous reduction of energy storage cost and the prominent role of energy storage in peak shaving and valley filling, energy saving and carbon reduction, it can be used as a key investment area in the future. For cement enterprises with abandoned mines, they can invest in the construction of decentralized wind farms according to local conditions when conditions are available. It is necessary to promote the application of new energy heavy trucks, biomass power generation and waste heat utilization in the cement industry.

Zou Weibin pointed out that the development of cement industry will focus on "clean production, energy saving and emission reduction", and carry out various technological innovations, including the development and application of high-efficiency and energy-saving grinding equipment and new technology, so as to reduce the power consumption of grinding system. "System energy saving is the absolute principle": the inheritance, innovation and development of the traditional grinding theory; the continuous summary and continuous improvement of the grinding system according to the actual process conditions, and the acceleration of technological progress.

Gao Yuzong pointed out that the difficulty of the alternative fuel technology scheme lies in the mode of collecting and storing biomass. The key point is that the type of furnace used to incinerate biomass depends on the type of long-term main disposal. The technical route is as follows: biomass enters the plant-temporary storage-crushing-closed transportation-metering into the incinerator-incineration-high-temperature flue gas enters the decomposition furnace-residue is discharged or enters the furnace-tertiary air or natural air can be used for combustion support-offline or online arrangement. The key point is that the key factors affecting cost and benefit are transportation distance and moisture, and fire protection and stable supply capacity are equally important.

Jia Huaping emphasized that in order to break the shackles of existing experience with dialectical thinking, oxygen enrichment is not the key to the oxygen-enriched calcination of cement kilns, but only requires reliable equipment operation and stable gas oxygen content. The key is calcination, "calcination" is the professional and responsibility of cement producers, lack of experience should be explored and summarized by themselves.

The one-and-a-half-day conference provided an open platform for communication, discussion and learning for the industry, and the scene was full of guests and warm atmosphere. On the afternoon of July 7, the participants will also visit Dongfang Hope Chongqing Cement Preheater "Level 5 to Level 6" Energy-saving Demonstration Line and Steam-driven Fan Energy-saving Project.
