Abstract
This study is an attempt to burn Pulverized Refuse-Derived Fuel (P-RDF) prepared from municipal solid waste (MSW) for recycling of waste resources. New experimental apparatus and method were established in order to obtain fundamental data of P-RDF combustion in a furnace. A small amount of P-RDF in the fuel holder were heated up by high temperature flow gas under a variety of O2concentrations. The pyrolytic and burnt gases were extracted by a water-cooled sampling probe, and then these compositions were analyzed by a FT-IR gas analyzer. The effects of temperature and O2concentration on the composition in flue gas were investigated in order to elucidate pyrolytic or combustion mechanisms of P-RDF. Results showed that the pyrolytic and burnt gases include components such as nitrogen oxide, carbon monoxide, carbon dioxide, methane, ethylene, ethane and propylene, and the main component of the pyrolytic hydrocarbonic gas is methane. The concentrations of the pyrolytic and burnt gases mentioned above were raised with an increase in temperature and O2concentration in flow gas. In particular, fuel NO was observed even in the low temperature of 400°C in N2gas flow.
