Numerical investigation on residence time of cooling water and surface temperature distribution of water-cooled grates

摘要: Waste incineration is a treatment system that reduces waste volume while capturing or destroying potentially harmful substances and recovers energy chemical contents from wastes. Grate incinerator one of the thermal methods in incinerations. The grates are exposed to high heat flux due occurrence combustion on their surface. Therefore, cooling grate main issues these treatments. In this study, conjugate transfer between water investigated numerically. We consider different geometries internal guide vane channel analyze effects shapes performance grate. also calculate fluid residence time investigate relation fluid. Results confirm maximum can be reduced, which improved.
