Abstract

Food Solid wastes (FSWs) can provide energy for blast furnace through combustion. The combustion characteristics and kinetics of waste meat (WM), waste steamed bread (WSB), waste rice (WR), waste vegetables (WV) and their mixture were studied by the non-isothermal thermogravimetric method. The combustion of FSWs could be divided into two stages: volatiles released and fixed carbon combustion. The first stage was all very intense, while the second stage was different. The fixed carbon combustion was prominent for WM and WV. The order of ignition point was the WV < WM < WR < WSB < coal. However, the order of burnout capacity was WV > WSB > WR > WM > coal. FSWs have a better combustion performance than coal and are better suited for blast furnace injection. The single waste promoted each other at the mixture combustion, ignition point was improved. The combustion activation energy of FSWs was far lower than the coal. The volatiles released were third-order chemical reactions for FSWs. Fixed carbon combustion of WSB and WR was the first order reaction, but that of WM, WV and their four mixture was cylindrical symmetry phase boundary reaction.
