Abstract
The present invention is a method, and an apparatus for practicing the method, that creates a product stream and a heat of reaction from a fuel-rich fuel/air mixture and then contacts the product stream with a sufficient quantity of additional air to completely combust all of the fuel, to which air a portion of the heat of reaction has been transferred.
Claims18
A catalytic reactor comprising:
- a) a housing having an entrance and an exit and an interior surface, the housing defining at least one aperture;
- b) a plate positioned within the housing defining a first zone and a second zone;
- c) at least two conduits made of a heat conducting material and adapted for conducting a fluid, the conduit having an entrance, an exit with a periphery and an exterior surface, the conduits positioned within the housing, such that:
- the conduits penetrate the plate whereby the conduit exits are in the second zone and the conduit entrances open into the first zone,
- the conduit exterior surfaces within the second zone and the housing interior surface within the second zone defining a flow path, the conduit exit peripheries defining at least one flow path exit, the conduit exits and the flow path exit being proximately located and interspersed, the flow path being in fluid communication with the aperture;
- and
- d) catalytic means for making at least a portion of the flow path catalytically active.
