Device for burning a fuel/oxidant mixture

摘要

A device for burning a fuel/oxidant mixture in a strongly exothermic reaction, consists of a reactor with a combustion chamber containing at least one first porous material and at least one second porous material in separate zones A and C. The zones are designed in such a way that an exothermic reaction can only occur in zone B, and with one or more feed lines for the fuel and for the oxidant, whereby zone A, which consists of the first porous material, is separated by a distance of approximately 10 mm to 4000 mm, for example approximately 20 mm to 500 mm, equating to one zone B, from zone C which consists of the second porous material and is located before zone C in a flow direction of the fuel/oxidant mixture.

主权项

1. A device for burning a fuel and oxidant mixture in a strongly exothermic reaction, the device comprising:
a reactor including at least one feed line for the fuel and the oxidant and a combustion chamber including at least one first porous material in a first zone and at least one second porous material in a separate second zone, said combustion chamber, said at least one first porous material and said at least one second porous material being formed from materials resistant to temperatures of approximately 1600° C. to 2400° C., said at least one second porous material having a sufficiently high heat capacity to restart a combustion reaction following a short-term interruption of gases, said first zone and said second zone configured such that the exothermic reaction can occur only in said second zone, said first zone being located before said second zone in a flow direction of the fuel and oxidant mixture and at a distance of between approximately 20 mm and 500 mm from said second zone, said distance of approximately 20 mm and 500 mm between said first zone and said second zone defining a third zone; and a support grate located at an interface area and configured to be cooled.
