Numerical Analysis of Depollution of Smoke Produced by Household Wastes IncinerationSource: Journal of Heat Transfer:;2012:;volume( 134 ):;issue: 004::page 41203DOI: 10.1115/1.4005204Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study reports the results on a numerical investigation of the depollution of smokes produced by the incineration of household wastes in a cylindrical furnace. Transfers are described by double-diffusive mixed convection equations, associated to radiative transfer equation, and a global kinetics model. The governing equations are discretized using finite volume method and the resulting algebraic equations are solved by THOMAS algorithm. The linkage between the pressure and velocity fields is assumed by SIMPLE algorithm. Results are presented as streamlines, isotherms, isoconcentrations for different Reynolds number (300 ≤ Re ≤ 1800). Effects of Reynolds number, relative height opening, aspect ratio, excess air ratio, and radiative transfers on gas pollutants (CO, CH4 , C2 H4 …) destruction are investigated in detail.
