Optimization of the slag tap for the gasification of sustainable feedstocks
Metadata[+] Show full item record
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.
