Investigation on Combustion Characteristics of Sewage Sludge Solid Fuels using Pilot-scale Bubbling Fluidized Bed Reactor

摘要

In this study, combustion characteristics of sewage sludge solid fuel produced by pretreatment based on hydrothermal carbonization process are discussed. In thermogravimetric analysis results, there are two burning sections. This tendency is more prominent in SS compared to WP. As a result of experiment using bubbling fluidized bed reactor, the temperature and pressure of the reactor were kept stable. But CO, NO_x and SO_x emissions of SS were higher than that of WP. Moreover, the ash deposition tendency of SS was predicted highly.
