Original Abstract
Secondary combustion chambers belong to key equipment in units for thermal processing of waste, including waste to energy systems. The design of secondary combustion chambers used in hazardous waste incinerators and their operating conditions pose a difficult engineering problem. The currently prevalent approach in designing and operating these secondary combustion chambers involves only simple balance calculations and intuitive engineering solutions. However, considering investment and operating costs, secondary combustion chambers constitute very significant budget items. Aim of this work is therefore to identify possible savings through a careful CFD analysis of a real industrial secondary combustion chamber working as part of a hazardous waste incinerator. Priority in the optimisation is given to flawless functionality (meeting environmental limits represents a crucial issue). Maximum care has been taken to make the CFD computations as reliable as possible in order to provide a dependable basis for drawing conclusions and design recommendations. This included the following measures: CFD results were validated by calculated balance data, second order upwind differencing has been used throughout the work, and advanced Reynolds-stress model has been used for turbulence modelling.
