Abstract
Recent studies of spiral counterflow "Swiss-roll" heat-recirculating reactors have demonstrated the importance of streamwise heat conduction on their performance. Titanium Swiss rolls having a thermal conductivity (k) of 7.1 W/m-K, geometrically similar to inconel 718 reactors (k = 11.1 W/m-K) studied previously, were constructed to test this hypothesis using propane-air mixtures with specially-prepared Pt catalyst. Three different wall thicknesses were studied. As suggested by theoretical studies, better performance was found for low-k, thin-walled reactors. Under these conditions, self-sustaining chemical reaction could be maintained at maximum temperatures below 55°C with ignition temperatures below 90°C. These results may be useful for development of micropower generation devices employing thermoelectrics or solid-oxide fuel cells.
