Optimising design of secondary combustion chambers using CFD

Optimising design of secondary combustion chambers using CFD

Paper in proceedings (conference paper)

Secondary combustion chambers belong to key equipment in units for thermal processing of waste, including waste to energy systems. This work uses a real industrial chamber as a baseline in simulations. Work presented here continues with finding of ideal proportions of cylindrical secondary combustion chamber (height/diameter ratio). The aim of this work is to find minimal tolerable height/diameter ratio which will secure the environmental limits and which will have the minimum investment costs. For this purpose, the baseline geometry has been slightly modified to compare with other simulated geometries. Total count of five alternative geometries has been simulated and results have been compared.
