A study was conducted on the process flow and operating parameters of the new dry-process technology currently available in the cement industry in Heilongjiang Province, and input and output data of the established product system were collected and calculated and quantified.新型干法窑生产硅酸盐水泥。对黑龙江省水泥工业目前所具备的新型干法工艺的工艺流程和工业运行参数进行研究，收集了所确定产品系统的输入、输出数据，并对数据进行了计算、量化。9The portland cement produced using the new dry process kiln technology is utilized mainly in the construction industry. It is suitable for constructing infrastructures such as buildings, highways, and bridges where a high level of durability and strength is required. The cement, with a specified 28-day compressive strength of 42.5MPa, is appropriate for structural concrete and other applications where 42.5MPa of strength is necessary.新型干法窑技术生产的硅酸盐水泥主要用于建筑行业。适用于建设需要高耐久性和强度的基础设施，如建筑物、高速公路和桥梁。该水泥具有指定的28天抗压强度为42.5MPa，适合结构混凝土和其他需要42.5MPa强度的应用。MSPWbT0ytoX9vbx6j29cuUHonYc.pngThe functional unit is the performance of 1kg cement with a 28-day compressive strength of 42.5MPa, that is, 1Fu=42.5kgMPa. The scope of evaluation is raw meal preparation, clinker calcination and cement preparation. The environmental load caused by the consumption of clay resources is not considered for the time being. Iron powder is an iron correction material, and its environmental impact will not be considered. The wastes considered to be emitted at the output end of the product system mainly include nitrogen oxides, sulfur dioxide, carbon dioxide and dust.以1kg28天抗压强度为42.5MPa的水泥所具有的使用性能作为功能单位，即1Fu=42.5kgMPa。评价范围为生料准备、熟料煅烧和水泥制备。粘土类资源消耗造成的环境负荷暂不考虑。铁粉属于铁质校正材料，其引发的环境影响不予考虑。产品系统输出端考虑排放的废弃物主要包括氮氧化物、二氧化硫、二氧化碳及粉尘。Unit process, black boxNone无None无None无None无None无于淼.

When utilizing this LCA data for the cement production process, ensure that the data corresponds accurately to the new dry process kiln technology. In modeling the cement production lifecycle, exclude the environmental load caused by the consumption of clay resources and the environmental impact due to the use of iron powder as a correction material. Consider the emissions of nitrogen oxides, sulfur dioxide, carbon dioxide, and dust in the impact assessment, as these are significant pollutants emitted from the cement production. The functional unit of the dataset is based on 1kg of cement with a 28-day compressive strength of 42.5MPa.在使用此水泥生产过程的LCA数据时，确保数据准确对应新型干法窑技术。建模水泥生产生命周期时，排除粘土资源消耗造成的环境负荷和作为校正材料的铁粉使用引起的环境影响。在影响评估中考虑氮氧化物、二氧化硫、二氧化碳及粉尘的排放，因为这些是水泥生产中排放的重要污染物。数据集的功能单位基于1kg28天抗压强度为42.5MPa的水泥。Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044.清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。Tiangong LCI Data Working Group天工LCI数据工作小组#REF!, ysqsophia@gmail.comysqsophia@gmail.comysqsophia@gmail.com2024-03-19T21:18:09+08:002024-04-20T14:40:42.232438+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=47999da2-6d54-4af2-a11d-47ca84c3da76&version=01.00.000&stock=TianGongTiangong LCI Data Working Group天工LCI数据工作小组falseFree of charge for all users and useslimestone, crushed, for millInput1104.41104.4Limestone石灰石gypsum stone (CaSO4-dihydrate)Input58.758.7Gypsum石膏ashInput319.4319.4Fly ash粉煤灰hard coalInput100.526100.526Standard coal.
