Abstract:
A furnace structure includes a roof assembly of at least one layer of refractory material, and a metal plate that covers the at least one layer of refractory material and is configured to dissipate heat from the furnace structure; a plurality of sidewalls fixed to the roof, each of the sidewalls comprising refractory material at an interior surface and a metal wall plate at an outer surface; and a plurality of infrared emitters disposed in an opening in at least one of the refractory material of the sidewalls or the refractory material of the roof.
Abstract:
A highly durable, high-strength thermal shield element is provided for the interior lining of the combustion chamber of a gas turbine. For this purpose, the thermal shield element comprises a base produced from a solidified cast ceramic material into which a plurality of reinforcing elements are integrated, to increase the tensile strength of the thermal shield element.
Abstract:
A turbine blade or vane for use in a gas turbine is to have as long a service life as possible at high strength. To this end, the turbine blade or vane, according to the invention, has a basic body which is formed from a strengthened cast ceramic material and in which a number of reinforcing elements are placed.
Abstract:
A REFRACTORY BRICK ADAPTED FOR USE IN FURNACE ROOF CONSTRUCTION AND HAVING SIDE FACES AND END FACES AND A CASING SHEET OF OXIDIZABLE METAL CARRIED ON AT LEAST ONE OF THE SIDE FACES, THE CASING INCLUDING A SHEET CHARACTERIZED BY A PLURALITY OF SPACING PORTIONS PROJECTING FROM ONE SURFACE AND A PLURALITY OF RECESSES DISPOSED IN THE OTHER SURFACE THEREOF IN ALIGNMENT WITH THE SPACING PORTIONS, INDIVIDUAL SPACING PORTIONS AND RECESSES BEING DISCONTINUOUS WITH RESPECT TO A STRAIGHT LINE DISPOSED IN THE PLANE OF THE SHEET. PREFERABLY, THE SPACING PORTIONS ARE DISPOSED IN SURFACE ENGAGEMENT WITH THE BRICK SIDE FACE AND FUNCTION TO SPACE THE ONE SURFACE OF THE SHEET THEREFROM. THE RELATIVE SIZE, CONFIGURATION AND POSITIONING OF THE SPACING PORTIONS AND RECESSES OF THE SHEET PERMITS SUBSTANTIALLY COMPLETE OXIDATION THEREOF DURING USE WITHOUT RESULTING IN GROWTH IN OVERALL SHEET THICKNESS, PREVENTS INTERLOCKING OF LIKE SHEETS CARRIED ON ADJACENT BRICKS DURING INSTALLATION THEREOF IN A FURNACE ROOF, AND MAINTAINS UNIFORM BEARING STRESS CONDITIONS IN FURNACE ROOF BRICK JOINTS.
