Smokes flow in incinerator Smoke flow patterns inside a waste incinerator Hot gas flow modelling CLIENT VINCI ENVIRONNEMENT LOCATION Clermont-Ferrand (63) - France DATE 2012 GOAL High temperature flow modelling inside a waste incinerator SOFTWARE FLUIDYN-MP Context and objectives VINCI Environment wanted to qualify the flow patterns in the post-combustion chamber of a boiler exchanger. The objective was to ensure the good mixture of the smoke at the outlet to avoid recirculation zones, hot spots and high residual time. Our skills The aeraulics and heat transfers in the afterburner have been modeled in the software Fluidyn-MP. The 3D-CFD simulation includes :The combustion of unburnt hot gases from the waste pyrolysis,The heat conduction in the walls of the incinerator,The radiation of hot gases
