Pyrolysis behavior of refuse derived fuel

RDF pyrolysis behavior over a temperature range of 773 to 1173K is experime ntally investigated by measuring released gas composition and accumulative gas volume in it pyrolysis process for three kinds of RDF, The major combus tible components in the released gas were CO, H-2, CH4, C2H6, C2H4, C3H8 an d C3H6. A rise in pyrolysis temperature resulted in improved content of com bustible gas components, particularly H-2 and CH4. The total heating value of the released gas is dependent upon the temperature and the type of RDF, and higher temperature improves the recycle energy efficiency converted int o inflammable gas from RDF, but reduces the volumetric heating value of the gas. The amount of total gas yields can be expressed by a function of temp erature and volatile matter content in raw materials regardless of the type of RDF.
