Waste incineration in a small incinerator is a simple and convenient way of treating waste discharged from small areas or from large facilities and buildings such as business centers, marketplaces, factories, and military units. Despite their ostensible advantages, however, many small incinerators frequently suffer from serious problems, e.g., unsystematic waste feeding, unstable combustion, deficient air pollution control devices, and consequently, environmental pollution. To obtain a better understanding of the characterization of wastes in small incinerators, we investigated a series of fundamental characteristics, i.e., physical composition, bulk density, proximate and ultimate analysis, potential energy content, and so on. The main waste components in small incinerators were identified as paper and plastic; the proportion of food waste was less than that in large incinerators. Especially, a low ratio of food waste had a strong influence on other waste characteristics, e.g., lower moisture content and bulk density, and higher potential energy. On the other hand, in contrast with that of HCl, there was no distinguishable linear relationship between Cl content in waste and PCDD/DF concentration in combustion gas.
小型焚烧炉中的垃圾焚烧是处理小区域或大型设施及建筑（如商业中心、市场、工厂和军事单位）排放垃圾的一种简单便捷方式。然而，尽管它们表面上有优势，但许多小型焚烧炉经常存在严重问题，例如垃圾进料不系统、燃烧不稳定、空气污染控制装置不足，结果导致环境污染。为了更好地了解小型焚烧炉中垃圾的特性，我们研究了一系列基本特性，即物理组成、堆积密度、近似和最终分析、潜在能量含量等。小型焚烧炉中的主要垃圾成分被确定为纸张和塑料；食物垃圾的比例低于大型焚烧炉。特别是，食物垃圾比例低对其他垃圾特性有很大影响，例如含水量和堆积密度较低，潜在能量较高。另一方面，与HCl不同，垃圾中的Cl含量与燃烧气体中PCDD/DF浓度之间没有明显的线性关系。
