waste fungus sticks, waste branches, pulp residues and other agricultural and forestry wastes, which are not valued, are crushed into blocks through several processes such as crushing, mixing, extrusion and drying, and become a new clean fuel that can replace traditional energy coal-biomass fuel, which has the advantages of green, harmless and low price. This application also enables Luoyang Zhonglian to run out of "acceleration" on the road of low-carbon environmental protection and green development. In his important speech during the deliberations of the Jiangsu delegation at the Second Session of the 14th National People's Congress, General Secretary
Xi Jinping stressed that new quality productive forces should be developed according to local conditions. Chairman Zhou Yuxian also proposed at the 2024 working conference of China Building Materials Group that the basic building materials business should accelerate high-end, intelligent and green development through continuous innovation to achieve a breakthrough in adversity. Luoyang Zhonglian resolutely implements the decision-making and deployment of the Party Central Committee, the Group Company and Tianshan Materials, and runs innovation through the whole process of high-quality development, from green and intelligent upgrading and transformation to the application of new technologies and equipment and the development of new products, constantly seeking new chapters, opening new situations and seeking development.
Luoyang Zhonglian is located in Ruyang County, Funiu Mountains, which is a famous mushroom planting base and timber processing site in China. 150 million bags of mushrooms are planted annually. There is a large market for waste disposal after mushroom planting and wood products processing.
After full market research, Luoyang Zhonglian, based on its own advantages in the co-disposal of solid and hazardous wastes, simulated the biomass fuel substitution experiment. According to the material composition, the corresponding recovery standards were formulated, and the waste bacteria sticks, waste branches and biomass RDF fuel rods were tested in batches. After reaching the standard, the fuel is crushed by a crusher and then transported to a hot plate furnace for full combustion.
Through unremitting efforts, Luoyang Zhonglian has made new breakthroughs in exploring the use of high calorific value solid hazardous waste and biomass alternative fuels. Firstly, the calorific value of the current solid hazardous waste and biomass alternative fuel is increased by about 600 kilocalories on average, and the burnout time of the solid hazardous waste and biomass alternative fuel is reasonably adjusted to ensure the clinker quality and continuous and stable operation. And secondly, by adjust that position of the kiln tail coal pipe and finding a prop opening, the decomposition rate of the kiln is improved to more than 95%, and the utilization rate of the tail coal is greatly improved. Thirdly, by adjusting the air consumption of the kiln, controlling the air leakage of the system and optimizing the operation of the grate cooler, the temperature of the tertiary air is increased by about 40 degrees, which further helps the combustion of solid hazardous waste and biomass alternative fuels. After a series of adjustment measures, the pulverized coal consumption of the calciner is reduced by 3 t/H, and the maximum physical coal consumption can be saved by 13. 6 kg/t. A large number of data show that the use of 3 tons of biomass fuel per hour can reduce 1 ton of raw coal consumption, reduce 2. 25 tons of CO2 emissions, and is expected to reduce 2370 tons of CO2 emissions per year.
Green development is the background of high-quality development, and new quality productivity itself is green productivity. Next, Luoyang Zhonglian will earnestly study and implement General Secretary Xi Jinping's important exposition on new quality productivity, adhere to the new development concept, take the development of green manufacturing industry as the orientation, constantly explore the use of green low-carbon energy, accelerate scientific and technological innovation and the popularization and application of advanced technology, and strive to achieve green low-carbon circular economy. Promote the company to high-end, green, intelligent direction.
