Abstract
Municipal Solid Waste (MSW) incineration is among the important opportunities
to control the pollutions caused by improper dumping and flue gas
emissions so as to meet the environmental guidelines. The objective of this
study was to design and develop a model for the MSW incineration process.
The paper explains the design and development of MSW incinerator involving
details of the Computational Fluid Dynamics (CFD) procedures through
model design to the post process. CFD model was developed to reveal these
features of the incineration process in the MSW incinerator. The model predicts
the temperature in combustion chambers as well as at stack outlet of the
incinerator. The solid waste characterization was done, and the laboratory
analysis shows that, the Higher Heating Value (HHV) of the MSW is 11.65
MJ/kg on dry basis. The elemental composition MSW consists of 54.8%,
5.27%, 34.61%, 2.37% and 0.3% for Carbon, Hydrogen, Oxygen, Nitrogen and
Sulphur respectively which are the input parameters for the CFD. The model
simulation was positively achieved during combustion process and temperature
in combustion chambers ranged between 930 K and 1700 K.
