Patent ID: 7182923

Claim:
A device amenable to chemical conversion of a feedstock, said device comprising in combination: an outer chamber envelope ( 2 a ) comprising an inlet orifice ( 5 ) and an outlet orifice ( 10 ); an assembly of modules comprising at least two heat transfer modules ( 44 ) configured in series, said assembly being disposed within said outer chamber envelope ( 2 a ), each of said heat transfer modules comprising a metal jacket ( 40 ) housing a circulation pipe ( 3 ), an inlet and an outlet to said circulation pipe, and at least one wall ( 11 , 12 ) made of refractory material, wherein the inlet of a first heat transfer module in the series of heat transfer modules defines an inlet orifice of the assembly of modules, and wherein the outlet of a final heat transfer module in the series of heat transfer modules defines an outlet orifice of the assembly of modules; each of said heat transfer modules including heat exchange means ( 4 ) comprising an exchange surface arranged in said pipe; first flexible connecting means ( 41 ) for collectively connecting said metal jacket ( 40 ) of each of said heat transfer modules to said outer chamber envelope ( 2 a ); and second flexible connecting means comprising two flexible means ( 46 ) for connecting the inlet orifice of the assembly of modules to the inlet orifice of the outer chamber envelope ( 2 a ) and for connecting the outlet orifice of the assembly of modules to the outlet orifice of the outer chamber envelope ( 2 a ), wherein two consecutive heat transfer modules are connected to one another such that the outlet of a preceding heat transfer module is connected to the inlet of a successive heat transfer module by a third flexible connecting means ( 45 ).
