Based on the concept of RDF(Refused Derived Fuel) pyrolysis by partial combustion and subsequent gas combustion

a reactor with two reaction zone (a spouting-moving bed pyrolyzer and a gas combustor) was developed

which was proposed for thermal disposal of solid wastes especially RDF. The RDF produced in the authors’ laboratory was used to evaluate the performance of the reactor. RDF was continuously fed to the spouting-moving bed pyrolyzer in which RDF was partially burned to supply heat for pyrolysis of RDF at a lower temperature

then the pyrolysis product gas was burned with secondary air at a higher temperature in the upper combustor. The flow-rate effects of spouting air

auxiliary air and secondary air on the profiles of temperature and pyrolysis gas composition were measured.
