| 20100190123 | Burner Plate Assembly for a Gas Oven - A wire mesh burner plate for use in large, gas burners for large ovens is comprised of spaced-apart wire mesh plates. The spacing between the wire mesh plates defines an air/fuel mixture space. The fuel passes through the lower or first mesh, experiences a pressure drop, mixes with air and passes through a second wire mesh. The gas combusts after passing through the second wire mesh. The fine gauge of the mesh prevents combustion from flowing backwardly into the fuel/air mixture space. Several individual wire mesh burner plates can be flexibly attached to each other such that a very wide space can be covered. Thermal stresses are reduced by being distributed across multiple burners. | 07-29-2010 |
