Abstract
Abstract An improved temperature distribution reactor-burner assembly, consisting essentially of a burner insert having a straight section and an inwardly tapering section serving to choke the flow of hot combustion gases in the vortex burner at the location where increased heat transfer to the reactor can be desired. Heat-transfer fins are disposed on the external wall of the reactor can to increase the area exposed to the swirling exhaust gases. The fins function to absorb and block radiation from the swirling combustion flames and the hot burner walls.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
53 words
A burner-reactor assembly as in claim 1, wherein said reactor canister further includes an upwardly extending prereactor chamber, said burner-reactor assembly further including an insulating sleeve disposed against the housing inner wall above and adjacent to the truncated conical section of the burner insert and surrounding said prereactor extension to the reactor canister.
Claim 2
Dependent Claim
39 words
A burner-reactor assembly as in claim 2 wherein the burner insert extends upward a sufficient distance to enclose essentially the reactor chamber of the reactor canister and the insulating sleeve encloses essentially the prereactor chamber of the reactor canister.
Claim 3
Dependent Claim
33 words
A burner assembly as in claim 3, wherein the heat-transfer fins are tangent to helices and cooperate with the swirling flow to minimize pressure loss through the finned section of the burner cavity.
Claim 4
Dependent Claim
117 words
In a fuel cell reformer having an essentially cylindrical reactor extending into a vortex burner, said reactor having a catalyst bed disposed therein, the improvement comprising a burner insert disposed against the inner burner walls and enclosing at least a portion of said cylindrical reactor to define a burner cavity therebetween, said insert having a cylindrical section and an inwardly and upwardly tapering truncated conical section serving to choke the outward flow of swirling combustion gases and fins attached to the external periphery of a portion of the reactor projecting into the space enclosed by said inwardly and upwardly tapering section of the insert to increase heat transfer to the reactor chamber and to increase thermal efficiency.
Claim 5
Dependent Claim
33 words
The improvement as in claim 5 wherein the external fins are tangent to helices and cooperate with the swirling combustion gases to minimize pressure loss through the finned section of the burner cavity.
