Inventor: MIURA TAMOTSU
IPC: F23D14/16
Filed: 1985-09-13
Abstract: PURPOSE:To obtain stable surface burning at high burning load by placing an adequate number of recessed parts having specified size at the surface in the surface burning side of a burning stabilizer for a surface burning burner composed of a ceramic particle layer. CONSTITUTION:Irregular polygonal ceramic particles are formed into a flat plate-shaped combustion improver 2 with inorganic binders such as alumina-sol or water-glass. At the burning side surface of the burning stabilizer an adequate number of concave parts having such specified shape as rectangular parallelogram, cylinder or divergent trapezium are installed. Surface burning of the combustion improver yields small pressure loss in the recessed parts and large pressure loss in the projected parts. Therefore, when input quantity of mixed gas is increased, stable and fine flame is formed and exhibits function of pilot burners at those projected parts and at the projected parts lifting of flame is prevented though flow velocity of mixed gas is increased at the recessed parts, and gas mixing function peculiar to a ceramic particle layer and effect caused by uniformity characteristic in gas flow have combined to obtain stable high load burning.
