Fuel processor for distributed hydrogen production

A combustor preheater (94) is provided for use in a fuel processor (20) to preheat a combustor feed (40) by transferring heat from a post water-gas shift reformate flow (32) to the combustor feed (40). The combustor preheater (94) includes a housing (92) defining first and second axially extending,...

Zusammenfassung:	A combustor preheater (94) is provided for use in a fuel processor (20) to preheat a combustor feed (40) by transferring heat from a post water-gas shift reformate flow (32) to the combustor feed (40). The combustor preheater (94) includes a housing (92) defining first and second axially extending, concentric annular passages in heat transfer relation to each other; a first convoluted fin (96) located in the first passage to direct the post water-gas shift reformate flow (32) therethrough and a second convoluted fin (98) located in the second passage to direct the combustor feed therethrough.
