Abstract
A process oven includes a housing structure with a conveyor system configured to carry product through a housing structure from a first opening to a second opening. A perforated flame holder is positioned within the housing structure and configured to apply, to the product, thermal energy released by a combustion reaction held by the perforated flame holder.
Claims54
A heater system, comprising:
- a tunnel structure having an input end and an output end;
- a conveyor system configured to carry a product through the tunnel structure from the input end to the output end;
- and
- a perforated flame holder positioned inside the tunnel structure and configured to apply, to the product, thermal energy released by a combustion reaction held by the perforated flame holder, the perforated flame holder including:
- a first face,
- a second face parallel to the first face, and
- a plurality of apertures extending through the perforated flame holder from the first face to the second face.
4 more elements
A device, comprising:
- a housing structure having first and second openings;
- a conveyor system configured to carry a product through the housing structure between the first and second openings;
- and
- a perforated flame holder positioned within the housing structure, and having a first face, a second face lying opposite the first face, and a plurality of apertures extending through the perforated flame holder between the first and second faces, the perforated flame holder being configured to hold a combustion reaction substantially within the plurality of apertures.
1 more element
A method, comprising:
- placing a product piece on a transport surface of a conveyor system;
- carrying the product piece into an oven housing by operation of the conveyor system;
- supporting a combustion reaction within a plurality of apertures extending through a perforated flame holder;
- applying thermal energy produced by the combustion reaction to the product piece as it is carried through the oven housing by the conveyor system;
- and
- following the applying thermal energy, carrying the product piece out of the oven housing by further operation of the conveyor system.
3 more elements
A heater system, comprising:
- a housing structure having first and second openings;
- means for conveying a product through the housing structure between the first and second openings;
- and
- means for holding a combustion reaction within the housing structure and emitting thermal energy as radiant heat toward the product.
