Thermodestruction of Wastes Generated by Thermal Processing of Household Wastes: Thermal Study of the Equipment in Laminar Regime

In this work, we conduct a thermal study on the installation of an incinerator of gas generated by the carbonization of household wastes. We used a forced and laminar flows, with Reynolds number ranging between 500 and 2,000. Beyond 2,000, in our simulation, computer programs are become more and more unstable, therefore showing that the regimen is no longer laminar. This combustion phenomenon is handled with Navier-Stokes equations, those on the energy and distribution of the species contained in smokes. Temperatures, around 650 K for a Reynolds number of 500, increase when this Reynolds number increases. Results show that the highest temperatures are near the walls of the incinerator. Given the quantity of energy released in these areas, thermal recovery is possible, but this must be properly done to minimize losses.
