Numerical Investigation of Swirl Enhancement for Complete Combustion in an Incinerator

摘要

Indeed, the entire country looks for to keep our environment neat and tidy. All form of wastes has some form of energy; normally it is incinerated to yield energy from it, and can be used to run gas turbines in power generation or mechanical drive applications. Incineration is one of the ways to control pollution, safe disposal of waste and need for landfill. Low emission level is great competitive in this world by burning all the given fuels in Engineering point of view. The work presented here is a numerical simulation of a cylindrical 3D combustion chamber, burning of all the given fuels without any residuals by providing Velocity Normal to Boundary (VNB) and Velocity Inclined to Boundary (VIB) with different approximations of fuel and oxygen by using CFD software, ANSYS-FLUENTTM. The present work takes incineration gases, Toluene and Benzene as fuel. It is found that creation of swirl inside the chamber and supply of excess amount of oxygen to the chamber, provide a complete combustion of given fuel. The numerical predictions would provide useful information for further analysis in this area.
