Bottom ash (BA) from waste-to-energy (WtE) plants contains valuable components, particularly ferrous (Fe) and non-ferrous (NFe) metals, which can be recovered. To assess the resource recovery potential of BA in the Czech Republic, it was necessary to obtain its detailed material composition. This paper presents the material composition of BA samples from all three Czech WtE plants. It was found that the BA contained 9.2-22.7% glass, 1.8-5.1% ceramics and porcelain, 0.2-1.0% unburnt organic matter, 10.2-16.3% magnetic fraction, 6.1-11.0% Fe scrap, and 1.3-2.8% NFe metals (in dry matter). The contents of individual components were also studied with respect to the BA granulometry and character of the WtE waste collection area.
底灰(BA)来自于废物能源化(WtE)工厂,含有有价值的成分,特别是铁(Fe)和非铁(NFe)金属,可以进行回收。为了评估捷克共和国 BA 的资源回收潜力,有必要获得其详细的材料组成。本文介绍了来自捷克三个 WtE 工厂的 BA 样品的材料组成。结果发现,BA 含有 9.2-22.7%的玻璃、1.8-5.1%的陶瓷和瓷器、0.2-1.0%的未燃烧有机物、10.2-16.3%的磁性部分、6.1-11.0%的废铁和 1.3-2.8%的 NFe 金属(干物质)。还研究了各个成分的含量与 BA 粒度和 WtE 废物收集区的特征之间的关系。
