Project Name: Sanming Jinniu Cement Cement Kiln System Energy-saving and Consumption-reducing Technical Transformation
Enterprise and Partner Name: Sanming Jinniu Cement Co., Ltd.
Main Construction Content: 0 HTML0UN K7 In this project, the cement process system will be technically transformed: 0 HTML0 UNK8 1.1 # and 2 # cement mills will be added with compound mineral powder to reduce the usage of 0 HTML0 UNK9 clinker 0 HTML0 UNK1 0; 0 HTML 0 UNK1 12. The technical transformation of changing the dust collector bag at the kiln end, after the technical transformation, the dedusting ventilation area is increased, the resistance is reduced, and the power consumption is saved; 0 HTML 0 UNK1 23. The solid waste dedusting powder is directly mixed and calcined at the kiln end, the use amount of raw meal powder is reduced, and then the use amount of raw material limestone is reduced, and the energy is saved; 0 HTML0 UNK1 34. Raw meal is directly mixed with aluminum ash for calcination, because Al2O3, the main component of aluminum ash, can be used as clay, thereby reducing the use of raw materials and saving raw material energy consumption; 0 HTML0 UNK1 45. Energy-saving transformation of kiln exhaust fan; 0 HTML0 UNK1 56. Energy-saving transformation of 1 # cement mill to increase production; 0 HTML 0 UNK1 67. Energy-saving reconstruction of automatic control of water system. 0 HTML0 014500 7 Starting and ending time of project construction: 0 HTML0 UNK1 8 January 2022-December 2023 0 HTML0 UNK1 9 Total project investment (ten thousand yuan): 0 HTML0 UNK2 014500 HTML0 UNK2 1 Comprehensive energy consumption of the project before transformation (ton of standard coal): 0 HTML0 UNK2 2 1103620 HTML0 41392 3 Estimated annual energy savings (tons of standard coal): 0 HTML0 UNK2 UNK2 490 HTML0 UNK2 520 HTML0 UNK2 6 Project name: 0 HTML0 UNK2 7 Energy-saving technical transformation project of rotary kiln cement production line with daily output of 4500 tons 0 HTML0 UNK2 8 Enterprises and Name of Cooperation Unit: 0 HTML 0 UNK2 9 Fujian Yong'an 0 HTML 0 UNK3 0 Million Year Cement 0 HTML 0 UNK3 1 Co., Ltd. 0 HTML 0 UNK3 2 Main Construction Content: 0 HTML 0 UNK3 3 The preheater of the burning system of the rotary kiln cement production line with a daily output of 4500 tons is opened by using the current domestic advanced energy-saving process equipment Expansion and transformation from stage 5 to stage 6, upgrading and transformation of grate cooler, energy-saving transformation of high temperature fan and head exhaust fan, transformation of coal mill to increase production, etc.; transformation of vertical mill to roller mill in raw material grinding system; transformation of limestone and clay crushing in raw material crushing system to increase production, etc. 0 HTML0 UNK3 4 project construction start and end time: 0 HTML0 UNK3 5 April 2023-December 2024 0 HTML0 UNK3 6 total project investment (ten thousand yuan): 0 HTML0 UNK3 7180000 0 HTML0 UNK3 8 comprehensive energy consumption of the project before transformation (tons of standard coal): 0 HTML0 UNK3 92441250 HTML0 UNK4 0 Estimated annual energy savings (tons of standard coal): 0 HTML0 UNK4 1186000 HTML0 UNK4 230 HTML0 UNK4 3 Project name: 0 HTML0 UNK4 4 Jiangle Jinniu Cement Co., Ltd. 3.4MW Stockyard Roof Distributed Photovoltaic Power Generation Project 0 HTML0 UNK4 5 Name of enterprise and cooperative unit: 0HTML0 UNK4 6 Jiangle Jinniu Cement Co., Ltd. 0HTML0 UNK4 7 Main construction content: 0HTML0 UNK4 8 The project plans to build a BIPV roof distributed photovoltaic power generation project in the material yard of the factory, with an installed capacity of 3.4M Wp. The mode of "spontaneous power consumption and surplus power access to the grid" is adopted. After the photovoltaic module is inverted and boosted to 10 kV, it is connected to the 10 kV photovoltaic incoming cabinet through the directly buried cable. The photovoltaic power generation is connected to the 10 kV distribution room of Jiangle Jinniu Cement Co., Ltd. at 10 kV voltage. The project is expected to generate 3 million kW.

Under the situation of imbalance between supply and demand, a single industrial structure has been unable to support enterprises based on the current complex market situation. Energy saving and carbon reduction, cost reduction and efficiency enhancement, industrial transformation and upgrading, optimization of asset allocation and enhancement of core competitiveness can maintain the healthy and long-term development of the cement industry. 0 HTML 0 UNK5 8 July 6-7, 2023, China Cement Network will hold "0 HTML 0 UNK5 92023 China Cement Energy Conservation and New Energy Development Conference 0 HTML 0 UNK60" in Chongqing, starting from energy-saving transformation, photovoltaic, energy storage and other technical applications, green electricity, alternative fuels to replace traditional energy transformation, etc. Explore new ways of energy saving and consumption reduction in cement industry. 0HTML0UNK61 After the meeting, we will visit Dongfang Hope 0HTML0UNK62 Chongqing Cement 0HTML0UNK63 preheater "level 5 to level 6" energy-saving demonstration line, steam driven fan energy-saving project, etc. 0HTML0UNK64
