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处理技术，对从燃烧到烟气处理的全过程进行了研究。现场的颗粒特性取决于温度，气体成分和其他燃料状态，实验模拟设备，能够控制这些参数已经开发和测试。通过模拟木材废弃物的初步燃烧试验，收集了木材废弃物燃烧特性的基本信息，并对模拟装置进行了改造。采用自行研制的采样器对颗粒物进行分类采集，将颗粒物分为10 μ m，2.5 μ m，1 μ m，0.05 μm四类，用气体分析仪测定CO、CO_2、SO_2、NO_2、O_2五种基本气体的浓度。为了减少水分对采样和测量的影响，在参考柴油机排气颗粒物的基础上，设计并开发了烟气稀释隧道。本课题的目的是研制一种能对可燃颗粒物和不可燃颗粒物的混合物进行燃烧状态研究的装置，通过对颗粒物中15种多环芳烃化合物的分析，探讨燃烧状态对颗粒物燃烧的影响。在基础实验的基础上，以聚酯废料颗粒为模拟废弃物。它们与二氧化硅颗粒混合并燃烧，作为模拟的不可燃废物。根据试验结果，讨论了混合比、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.
