Abstract
Various implementations provide an inherently safer design feature for microchannel reactors that provides temperature control at the individual channel level. This approach relies on bimetallic strips embedded within the combustion channel, forming a thermally-actuated “valve”. Bimetallic strips convert a temperature change into a mechanical displacement. Heating the strip increases its deflection and thereby restricts flow in the combustion channels, which consequently reduces the rate of heat generation. The thermally-actuated valve is not limited to use in microchannel reactors and may be used in other structures for which thermally actuated flow control is desired, according to some implementations.
