An integrated steam reformer/combustor assembly () is provided for use in a fuel processor () that supplies a steam/fuel feed mix () to be reformed in the assembly and a combustor feed () to be combusted in the assembly (). The assembly () includes a housing () defining first and second axially extending, concentric annular passages in heat transfer relation to each other; a first convoluted fin () located in the first passage to direct the feed mix therethrough, the first convoluted fin coated with a catalyst that induces a desired reaction in the feed mix; and a second convoluted fin () located in the second passage to direct the combustor feed therethrough, the second convoluted fin coated with a catalyst that induces a desired reaction in the combustor feed.

Highly integrated fuel processor for distributed hydrogen production

A combustor preheater () is provided for use in a fuel processor () to preheat a combustor feed () by transferring heat from a post water-gas shift reformate flow () to the combustor feed (). The combustor preheater () includes a housing () defining first and second axially extending, concentric annular passages in heat transfer relation to each other; a first convoluted fin () located in the first passage to direct the post water-gas shift reformate flow () therethrough and a second convoluted fin () located in the second passage to direct the combustor feed therethrough.

A recuperative heat exchanger () is provided for use in a fuel processor (), the heat exchanger () transferring heat from a fluid flow () at one stage of a fuel processing operation to the fluid flow () at another stage of the fuel processing operation. The heat exchanger () includes a housing () defining first and second axially extending, concentric annular passages in heat transfer relation to each other; a first convoluted fin () located in the first passage to direct the fluid flow therethrough; and a second convoluted fin () located in the second passage to direct the fluid flow therethrough.

A fuel processing system is provided wherein heat is transferred from a reformate flow () downstream from a water-gas shift () to both a) a combustor feed flow () that is supplied to a combustor (); and b) a water flow () that is supplied to a reformer feed mix () for a steam reformer ().
