A study was conducted on the process flow and operating parameters of the rotary kiln 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. 立窑生产硅酸盐水泥。对黑龙江省水泥工业目前所具备的立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 specific portland cement, characterized by a 28-day compressive strength of 42.5MPa, is suited for general construction purposes including infrastructure, buildings, and civil engineering projects that require a high grade of structural integrity. Its production process using a shaft kiln is particularly relevant to the region of Heilongjiang Province in the context of the current technological capabilities of the cement industry. 本硅酸盐水泥产品具有28天压强42.5MPa的特性，适用于要求较高结构完整性的普通建筑、基础设施、建筑和土木工程项目。其使用立窑的生产工艺适用于黑龙江省目前水泥工业的技术能力范围。 NK0Hb2UOgows9vxHdZic8RrUn8d.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 utilizing this data set, LCA practitioners should base their analysis on the functional unit of 1kg of cement with a 28-day compressive strength of 42.5MPa. Users should include emissions such as nitrogen oxides, sulfur dioxide, carbon dioxide, and dust in their impact assessment. The environmental impact of clay resource consumption and iron powder used as a corrective material should be omitted from the analysis at this stage. The methodological boundary includes raw meal preparation, clinker calcination, and cement production, and users should carefully consider the technological applicability of the shaft kiln which is specific to this regional industry. 当使用这份数据集进行生命周期评价时，分析者应以1kg具有42.5MPa 28天抗压强度的水泥为功能单位。用户应在影响评估中包括氮氧化物、二氧化硫、二氧化碳和粉尘等排放物质。目前阶段，来源于粘土类资源消耗和作为校正材料使用的铁粉的环境影响应从分析中省略。方法学范围包括生料准备、熟料煅烧和水泥生产，而且用户应仔细考量与该地区工业特定的立窑技术的适用性。 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 2024-04-20T14:40:39.845003+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=dcffcc2b-d964-46d2-94ed-0c7b3c5b0c75&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 1137.5 1137.5 Limestone 石灰石 gypsum stone (CaSO4-dihydrate) Input 59.3 59.3 Gypsum 石膏 hard coal Input 204.82 204.82 Standard coal.
