COMBUSTION ANALYSIS OF WASTE INCINERATION AND DEVELOPMENT OF HIGH EFFICIENCY WASTE MANAGEIVIENT SYSTEM BY WASTE COMBUSTION SIMULATOR EQUIPMENT

为了开发一种新的废物管理技术，对从燃烧到烟气处理的全过程进行了研究。现场颗粒物的特性取决于温度、气体成分和其他燃料状态，已经开发出能够控制这些参数的实验模拟设备并进行了测试。通过模拟木材废料的初步燃烧试验，收集了燃烧特性的基本信息，并对模拟设备进行了改进。用新研制的采样器对颗粒物进行分类采集，将颗粒物分为10μm、2.5μm、1μm和0.0 5μm四个等级，并用气体分析仪测定了CO、CO_2、SO_2、NO_2、O_2等五种基本气体浓度。为了降低采样测量过程中水分的影响，在参考有关柴油机排气颗粒物研究的基础上，设计开发了烟气稀释风洞。对颗粒物中的15种多环芳烃化合物进行了分析，以探讨燃烧条件的影响。本项目的目的是开发一种能够研究可燃和不可燃颗粒混合物等各种颗粒的燃烧状态的设备。在基础实验的基础上，利用涤纶坏颗粒作为模拟废物。它们与二氧化硅颗粒混合燃烧，作为模拟的不可燃废物。根据计算结果，讨论了掺混比、燃烧速率与颗粒特性之间的关系。

In order to develop a new waster management technology, whole process from combustion to flue gas treatment has been investigated. Site the particulate characteristics depends on temperature, gas composition and other fuel states, experimental simulator equipment which is capable of control of those parameters has been developed and tested. By preliminary combustion tests using simulated wood waste, basic information of combustion property has been collected and simulator equipment has been revised. Particulate matters axe classified and collected by newly developed sampler which separates them into 4 classes, 10 μm, 2.5 μm, 1 μm and 0.05 μm, and basic five gas concentration include CO, CO_2, SO_2, NO_2, O_2 are measured by a gas analyzer. To reduce the effect of moisture during those sampling and measurement, flue gas diluting tunnel has been designed and developed based on references on diesel exhaust particles. Fifteen PAH compounds in the particulate matter have been analyzed to discuss effect of combustion condition.Aim of the project is to develop a equipment which can investigate the combustion status of various wade such as mixture of combustible and incombustible grains. On the basic experiments, pet bad granules are used as simulated waste. They are mixed and combusted with silica granules as simulated incombustible waste. From the results, the relationship between mix ratio, combustion rate and particulate characteristics are discussed.
