数据集使用建议 | 使用本数据集的用户应确保在水泥窑替代传统燃料过程中考虑RDF的热值和燃烧特性。需监控并保持熟料的质量参数,如石灰饱和度系数(KH)、硅酸盐模数(SM)和铝酸盐模数(IM)以及热替代率(TSR)在规定的限度内,避免对熟料质量产生不良影响。对于原材料消耗量的计算,尤其是原料中替代原料的比例也至关重要,因为这会影响整个过程的物料用量和能效。用户应根据水泥生产的电力消耗指数计算每个生产阶段的电力消耗,并且认识到该过程中废水的生成量可以忽略不计。环境排放或废物的评估应符合所述系统边界:煤粉制备、生料制备和熟料煅烧。 |
产品或过程的技术目的 | 本数据集描述的由城市固体废物制成的垃圾衍生燃料(RDF)用于生产水泥的主要成分之一熟料。该RDF用作替代传统化石燃料例如煤,并主要由纸张、塑料、木材等轻质易燃物组成。市政废物中的不可燃部分,主要包括石灰土、砖、陶瓷、玻璃和金属,被用作熟料生产过程中的替代原料。该RDF的具体使用案例是在山东申丰水泥集团有限公司的水泥窑内,作为利用废物转能方法的一部分。 |

关于数据集的一般性意见 | 根据北京市住房和城乡建设委员会2021年发布的《北京市生活垃圾管理条例》,生活垃圾被分为食品垃圾(Food waste,FW)、其他垃圾(Residual waste,RW)、可回收物和危险废物。将生活垃圾转化为垃圾衍生燃料(Refuse-derived fuel,RDF)作为生产熟料的替代燃料。RW被筛分为两部分。超过尺寸的部分主要包含易燃材料,如纸张、塑料和木材。将它们与5%的石灰粉碎和压缩成为垃圾衍生燃料(RDF CDW),用作水泥窑炉中的替代燃料以取代部分煤。欠尺寸的部分主要由不可燃材料组成,如石灰土、砖、陶瓷、玻璃和金属,经过破碎后进入生料磨。FW与碎石灰预混,然后进入配料系统。它也被用作替代原料。FW不需要干燥,因为它的水分被石灰石预混利用。在情景中,熟料生产使用了石灰石、砂岩、页岩、铁粉、RW欠尺寸和FW作为原材料,以及煤和RDF CDW作为燃料。煤灰和RDF CDW灰也被用作原材料。考虑到熟料质量参数、热替代率(Thermal substitution rate,TSR)和原料中替代品的比例,调整了物料用量。每个阶段的电力消耗根据水泥生产的电耗指标进行计算。 |

技术说明,包括后台系统 | In scenario 4, the RW was divided into two parts with a sifter. The oversizemainly contained light combustibles, such as paper, plastic, and wood. They were crushed and compressed with 5% lime (Li, 2017) to make the refuse-derivedfuel (RDF CDW), which was used as an alternative fuel in the cement kiln to replace part of the coal. The undersize mainly consisted of incombustible, such as lime soil, bricks, ceramics, glass, and metals, which were fed into the raw meal mill after being crushed. The FW was pre-homogenized with crushed limestone and then entered into the batching system. It has also been used as the alternative raw material (Cai et al., 2014). There was no drying for FW because its moisture was just utilized by limestone pre-homogenization (Cai et al., 2015). Clinker production in scenario 4 used limestone, sandstone, shale, iron powder, the undersize of RW and FW ( ́ Swiechowski et al., 2020) as raw materials, and used coal and RDFCDW as fuels. Coal ash and RDF CDW ash were also used as raw ma terials. The clinker quality parameters, TSR, and proportion of alternative raw materials in the raw meal were considered as constraint conditions to adjust the material usage (Cai et al., 2015). The power consumption in each stage was calculated based on the electricity consumption index for cement production(Cai et al., 2015; Wang, 2013; Li, 2017). |
