Advances are being made in the gasification and melting processes for domestic waste. Still, more research is needed to achieve further energy recovery, effective resource utilization, and operating condition optimization. To date, we have established a pyrolysis reaction model using typical chemical substances that constitute municipal solid waste (MSW) .<BR>In the present study, we examined the effects of pyrolysis conditions and MSW composition on the amount of residue and the residue calorific value after pyrolysis using a new fixed temperature pyrolysis model. As a result, we were able to estimate the MSW calorific values from a composition sample using a model with calorific values of typical substances in MSW.<BR>Furthermore, we compared pyrolysis residue amounts and calorific values calculated in the pyrolysis model with those obtained experimentally using a tubular electric furnace. The results suggest that it is possible to estimate the amount of pyrolysis residue and the residue calorific value with this model and that it is effective in establishing efficient pyrolysis process operating conditions.
