Abstract
Mathematical modeling and computer simulation for the municipal solid waste incineration process
provides important understanding into the incinerator’s performance. The application of mathematical
modeling for the incineration process will increase the incinerator operating efficiency. The broad objective
of this study was to optimize the design of municipal solid waste incinerators using mathematical modeling
and computer simulation. Computation Thermal Predictions (CTP) relations involving different types of
incineration parameters such as temperature, density, velocity and species concentration were formulated
based on theories of incineration process with various assumptions. The solution of the mathematical model
developed was done and accomplished by Computational Fluid Dynamics (CFD). Finite element method
of numerical analysis was applied to solve the temperatures in the simulated incinerator model as well as
species/flue concentration at the end of its chimney. Dimensions used on the simulated model were applied
to construct the physical incinerator for analysis. Tests were performed on the physical model incinerator
and data used to validate the results obtained from the simulated model. Both simulated and experimental
results showed that it is possible to forecast temperature and flue gases by the application of mathematical
expressions. The incinerator CTP model was applied to simulate the incineration process and aid to regulate
temperature at different locations and species/flue concentration at the end of incinerator chimney. The
CTP results were very close to those obtained from experiment. The t-test method conducted revealed that
simulated and experimental results did not differ significantly at 0.05 level of significance. Therefore, there
is an agreement between the empirical model and experimental data as they show true trend of the
incineration process.
