PURPOSE: To provide a burner plate made of fiber ceramic and adapted to maintain a consistent combustion even at an elevated temperature such as 900°C or higher.
CONSTITUTION: A planar portion 1 is made of fiber ceramic with a fire-proof in organic fiber as a skelton, and has a convexed portion 2 formed on the surface thereof, said convexed portion 2 being continuously formed on the surface of burner plate in a diamond conical shape to form a burning surface. The diamond basic bottom of respective convexed portion 2 provided at the center of each side and each apex with flame ports 3a, 3b respectively piercing from the rear surface of burner plate. The top of convexed portion 2 is also provided with a similar flame port 3c. The convexed portion 2 is 2.5W5mm along one side of bottom, and 1.5W3mm in height. Flame ports 3a, 3b and 3c have the diameter of 0.8W1.6mm. These dimensions are varied depending on the type of combustion gas and a combustion condition. Thus, the flame ports defined through the top of convexed portion plus other flame port defined in its bottom serves to realize a stable combustion, and thereby maintaining a consistent combustion even at an elevated temperature.
