The MSW has been recognized as one of the promising alternative energy resource. Recently dioxin
emission has been social concern and the serious regulation less than 0.1ng/m3 was determined for newly
built incinerator. To overcome the serious problems of pollutants such as dioxin, NOx, CO and dust in the
MSW incinerator, densified RDF(refuse derived fuel) which is classified RDF-5 by ASTM standard is an
attractive technology to utilize MSW as the energy resources. Since RDF utilization technologies have
significant advantages in storage, transportation and constant heating value. Moreover, the calcium
component added in RDF has the capacity to control HCl emission level in flue gas and then higher energy
efficiency is expected. The RDF was produced from municipal solid wastes including papers, woods,
plastics and clothes for this experiment.
In this work, since the most combustible component of RDF is volatilized by pyrolysis, a RDF
combustor should be designed to achieve very good mixing and high reaction efficiency of the gas
flow field. In order to design the multi-hearth type RDF combustors having capacity of 60kg/hr,
computational fluid dynamics was employed to calculate the flow and reaction profiles along with
combustion experiments. Through this method imposed a limitation in accuracy, it was applicable
to investigate the flow performance governed by the secondary air jets. Using the simulation
results, the RDF combustor design including the nozzle arrangement of the secondary air and the
shape of the secondary combustion chamber was improved to minimize a dead volume of mixing
within the furnace, which resulted in longer residence time and efficient mixing. The results of
combustion experiment of RDF showed that the concentrations of CO, NOx, SOx and dust were lower than the regulations of flue gases emitted from the incinerator.
