Optimization of the slag tap for the gasification of sustainable feedstocks
Abstract
The objective of this study was to optimize a slag tapping block for use with a
molten slag bath containing slag from the gasification of biomass and municipal solid
waste feedstocks. Theoretical testing was conducted on the slag tapping block
implementing computational fluid dynamics and design of experiments. It was
desired to see how factors affecting the slag tap could be optimized to result in the
minimum required temperature of the slag bath to reduce costs associated with
auxiliary means of heating the slag bath.
