The main production facility is an external kiln decomposition production line with a daily output of 2,000 tons of clinker. The design capacity is an annual cement output of 700,000 tons. The process flow is roughly the same as that of Dry Process Plant A. The factory's production process layout is reasonable, the host equipment is mainly domestically produced, and key components are imported from abroad. The automation control level of the entire production line has reached the international advanced level in the early 1990s. The factory cement qualification rate and first-class product rate, rich labeling rate, bag weight qualification rate, uniformity qualification rate, etc. have always maintained 100%. In the first half of 1998, the No. 425 and No. 525 cement produced by Dry Process Plant B passed the product certification of the National Product Certification Center. In the second half of the year, the measurement confirmation system passed the ISO10012 on-site audit. 干法B厂水泥生产采用新型干法预分解技术，主要生产设施为一条日产 熟料2000吨窑外分解生产线,设计 能力为年产水泥70万吨工艺流程与干法A厂大致相同。 该厂生产工艺布局合理，主机设备以国产为主，关键部件从国外引进 ，整条生产线自动化控制程度达到90年代初国际先进水平。出厂水泥合格率和一等品率、富裕标号率、袋重合格率 、 均匀性合格率等 一 直保持100%。1998年上半年，干法B厂生产的普425号、普525号水泥通过国家产品认证中心的产品认证. ， 下 半年计 量 确 认 体 系通 过ISO10012现场审核 。 This dataset describes the production of Portland fly-ash cement with a strength of 44.6MPa, using a dry process precalciner kiln technology.

When applying this LCA data, users should note that the dataset is specific to dry process precalciner cement production lines with an output of 2,000 tons of clinker per day, achieving a yearly production of 700,000 tons of cement. Ensure that the use of this data aligns with the scope of the construction project in question and adheres to its technological and capacity specifications. Consider that the production process described excludes mining, transportation, and packaging of cement. Therefore, if a full life cycle assessment is required for your project, additional data for these excluded stages will need to be sourced and included. Lastly, emissions data within the dataset pertains to a specific volume of production, so for different production volumes, emissions data should be scaled appropriately. 在应用此LCA数据时，用户应注意数据集具体针对每日产出2000吨熟料的干法预分解水泥生产线，年产水泥量为70万吨。使用这些数据时，确保其与所涉建设项目的范围对齐，并遵循其技术和产能规范。请考虑所描述的生产过程不包括水泥的采矿、运输和包装。因此，如果项目需要全生命周期评估，则需要额外获取并纳入这些被排除阶段的数据。最后，数据集中的排放数据与特定生产量有关，因此对于不同的生产量，排放数据应相应调整。 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 2024-04-20T14:40:13.454621+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=66e50c51-410d-40c5-98dc-85015aed9287&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 1199.08387 1199.08387 limestone 石灰石 sandstone Input 0.008249604 0.008249604 sandstone 砂岩 iron, powder Input 28.58614616 28.58614616 Iron powder 铁粉 gypsum stone (CaSO4-dihydrate) Input 52.91704977 52.91704977 gupsum 石膏 ash Input 159.3728883 159.3728883 Fly ash 粉煤灰 freshwater Input 402.2388142 402.2388142 Fresh water 新鲜水 hard coal Input 139.8566539 139.8566539 The original data is 93.882kt standard coal, here converted to hard coal, the conversion formula is 1kg hard coal = 0.929kg standard coal. 原始数据为93.882kt标准煤，这里换算为硬煤，换算公式为1kg硬煤=0.929kg标准煤。 Electricity Input 396.40637628 396.40637628 Electricity 电力 particles (> PM10) Output 0.018832183 0.018832183 Dust, with an unspecified particle size, is treated as PM > 10 micrometers in diameter. 粉尘，未标明粒径，按PM>10处理。 particles (> PM10) Output 0.008441249 0.008441249 Smoke, with an unspecified particle size, is treated as PM > 10 micrometers in diameter. 烟尘，未标明粒径，按PM>10处理。 sulfur dioxide Output 0.009305314 0.009305314 Sulfur dioxide 二氧化硫 Nitrogen oxides Output 0.015038052 0.015038052 Nitrogen oxides 氮氧化物 carbon monoxide (fossil) Output 0.013556402 0.013556402 Carbon dioxide 一氧化碳 carbon dioxide (fossil) Output 886.7329524 886.7329524 carbon dioxide 二氧化碳 Water Output 157.5810615 157.5810615 The original text is industrial wastewater (i.e. wastewater from cement production). 原文是工业废水（即水泥生产废水）。 cement, portland fly-ash cement, 44.6MPa Output 1000.0 1000.0 The average grade of cement is 446. 水泥平均标号446号
