Abstract

Abstract

The pyrolysis char was produced from typical combustible components in MSW, and combustion behavior of which was evaluated based on both combustion activity and cleanliness. Biomass chars, prepared from raw materials such as pine wood, hardboard and orange peel chars, have relatively richer K/Ca content and less ordered carbon structure, leading to higher combustion activity and stability. The yields, texture structure and carbon structure of fossil fuel chars, such as PVC, tyre and chemical fiber fabrics chars, varied. Among which, the tyre char has a mesoporous structure and higher content of S and Zn. The NO_x concentration in the flue gas from biomass char combustion was relatively higher(140.7~385.5 mg/m³), while SO₂ concentration(1889.8 mg/m³) in the flue gas, and Zn content(198167 mg/kg) in the ash from tyre char combustion were relatively higher. Special attention should be paid on these pollutants in real practice.
