廃棄物焼却における初期熱分解の挙動

抄録

In order to incinerate heterogeneous fuel such as waste products completely, high excess air ratio was traditionally applied to the burning zone in the incinerator. However, from viewpoints of heat recovery efficiency and flue gas treatment, low excess air ratio at high temperature has been becoming more popular for the waste incinerator year by year. Meanwhile, technologies for NOx emission control should be stricter since high temperature and flame instability under low excess air incineration conditions intend to extend NOx formation. In this study, initial pyrolysis behaviors of wastes in their incineration processes were analyzed to investigate their contributions to NOx formations.
