| Summary: | Al-Qur’an is Holy Scripture of Islam therefore the printed text itself is treated with a
great deal of respect. Unavoidably, there are times when an Al-Qur’an needs to be
disposed and burning is one of the method but it require to make sure the scripture is
fully burnt and the ashes produce is in the controlled condition. The best way to done
this method is by using the Cyclone Combustion chamber. Cyclone combustor is known
as the separator of the ash from the gaseous products of the solid fuel. The objectives of
this study are to demonstrated the flow characteristic, identify velocity and temperature
distributions inside the combustor and to attain the complete combustion process with
stoichiometry amount of air is used. The parameters of the simulation were run by using
multiphase model, incompressible flow, Realizable k-epsilon turbulent method and heat
transfer. The simulation was done by using ANSYS FLUENT version 14.0. The paper�volatiles-air used as mixture phase and air as liquid phase. The inlets velocities for fuel
and air are 0.0254 m/s and 14.14 m/s. The simulation was run with prediction the
combustion already occur so the chamber walls was set as the hot wall with temperature
773K. Others walls, inlets and outlets were assumed at the ambient temperature, 303K.
The simulation results show that the design of inlets merge was influenced the mixture
velocity, the higher swirl effect and the temperature increased gradually in the spinning
and swirling manner occur can be visualized. The combustion mixture found as rich
mixture, so the new air inlet diameter or velocity been suggested for archive the
complete combustion. Simulation of new air inlet velocity shows that higher velocity
and stagnation temperature occur much faster and the temperature distribution in the
emission chimney was lower. As a result that chimney design may use other cheaper
capable material. |
