Catalytic reactor comprising metal radiation surfaces
The invention relates to a catalytic reactor comprising a combustion reaction chamber with catalytic reactor tubes filled with catalyst elements and metal radiation surfaces arranged in the chamber to improve heat transfer.
1. Catalytic reactor comprising a combustion reaction chamber which comprises a plurality of catalytic reactor tubes and at least one burner for producing at least one combustion reaction, said catalytic reactor tubes are at least partly filled with catalyst elements, wherein the combustion reaction chamber further comprises one or more metal radiation surfaces, said metal radiation surfaces are
arranged between the catalytic reactor tubes
having a length of at least half the length of the catalytic reactor tubes
arranged with at least a part of the metal radiation surfaces in a distance from the burner small enough to enable heat absorption from the combustion reaction to the metal radiation surfaces,
wherein the metal radiation surfaces are either woven metal radiation surfaces or made of metal gauze,
whereby the metal radiation surfaces improve the heat transfer and/or even out the heat transfer profile from the combustion reaction to the catalytic reactor tubes and the catalyst elements during operation of the catalytic reactor,
wherein said metal radiation surfaces are arranged so near the at least one burner that a flame of the burner will make flame attachment to the radiation surfaces.
2. Catalytic reactor comprising a combustion reaction chamber which comprises a plurality of catalytic reactor tubes and at least one burner for producing at least one combustion reaction, said catalytic reactor tubes are at least partly filled with catalyst elements, wherein the combustion reaction chamber further comprises one or more metal radiation surfaces, said metal radiation surfaces are
arranged between the catalytic reactor tubes
having a length of at least half the length of the catalytic reactor tubes
arranged with at least a part of the metal radiation surfaces in a distance from the burner small enough to enable heat absorption from the combustion reaction to the metal radiation surfaces,
wherein the metal radiation surfaces are either woven metal radiation surfaces or made of metal gauze,
whereby the metal radiation surfaces improve the heat transfer and/or even out the heat transfer profile from the combustion reaction to the catalytic reactor tubes and the catalyst elements during operation of the catalytic reactor,
wherein said metal radiation surfaces are arranged within a flame of the at least one burner.
