A study was conducted on the process flow and operating parameters of other rotary kiln technologies 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. 其他回转窑生产硅酸盐水泥。对黑龙江省水泥工业目前所具备的其他旋窑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。 8 2008 This data set describes the production process of portland cement with a 28-day compressive strength of 42.5 MPa, utilizing alternative rotary kiln technologies. The described portland cement is suitable for construction applications where high strength cement is required, such as the construction of infrastructure, buildings, and bridges. It is specifically applicable to the cement industry within Heilongjiang Province, involving the stages from raw meal preparation to cement preparation. 该数据集描述了使用其他回转窑技术的42.5MPa硅酸盐水泥的生产过程。所述的硅酸盐水泥适用于需要高强度水泥的建筑应用，例如基础设施、建筑物和桥梁的建设。具体适用于黑龙江省水泥行业，涉及从生料准备到水泥制备的阶段。 Cq3Vb4qR4o8VucxIWL1crTTjnEc.png The 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 box None 无 None 无 None 无 None 无 None 无 于淼.

When using this data set for Life Cycle Assessment (LCA), consider that the scope of evaluation includes raw meal preparation, clinker calcination, and cement preparation, but does not account for the environmental load caused by the consumption of clay resources nor the impact of iron powder as an iron correction material. Furthermore, when modeling the use phase behavior or interpreting the results, it is important to note that only nitrogen oxides, sulfur dioxide, carbon dioxide, and dust emissions are considered. Ensure that LCA studies incorporating this data are restricted to the use of portland cement in contexts with comparable technological applicability and industrial operating parameters. 在使用这个数据集进行生命周期评估（LCA）时，请注意评价范围包括生料准备、熟料煅烧和水泥制备，但不包括粘土资源消耗造成的环境负荷和铁粉作为铁质校正材料的影响。此外，在建模使用阶段行为或解释结果时，重要的是要注意，只考虑了氮氧化物、二氧化硫、二氧化碳和粉尘排放。确保将此数据纳入的LCA研究限于在具有可比技术适用性和工业运行参数的情况下使用硅酸盐水泥。 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.com ysqsophia@gmail.com ysqsophia@gmail.com 2024-03-19T21:18:09+08:00 2024-04-20T14:40:40.984770+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=d010eff6-8f9c-442a-afec-b81d5fba2744&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 false Free of charge for all users and uses limestone, crushed, for mill Input 1203.4 1203.4 Limestone 石灰石 gypsum stone (CaSO4-dihydrate) Input 59.0 59.0 Gypsum 石膏 hard coal Input 235.386 235.386 Standard coal.
