Plate type burner

Abstract

A plate type burner includes a burner main body and a plurality of burning plates mounted on the open surface of the burner main body. A flange portion enclosing the open surface is formed on the upper surface of the burner main body. The outer edge of each of the burning plates is placed on the flange portion with a sheet of packing interposed therebetween. The outer edge of each of the burning plates is pressed downward by a pressing plate. A clamping plane inclining downward to the outer side is formed on the upper surface of the outer edge of each of the burning plates. Furthermore, an inclined abutting portion contacting the clamping plane of each of the burning plates by a plane of the abutting portion is formed in the pressing plate.

1 . A plate type burner, comprising:
 a burner main body shaped in a box with an upper surface thereof being formed as an open surface;   a plurality of burning plates mounted side by side in the open surface so that a mixture gas is jetted for combustion from inside the burner main body through a multiplicity of burner ports formed in each of the burning plates;   the burner main body having formed on the upper surface thereof a flange portion in a manner to enclose the open surface, each of the burning plates being placed on the flange portion at an outer edge thereof with an annular packing being interposed therebetween such that, by pressing downward the outer edge of each of the burning plates by a pressing plate to compress the packing, sealing property is secured between the burner main body and each of the burning plates,   wherein an upper surface of the outer edge of each of the burning plates has formed therein a clamping plane inclining downward to an outer side; and   wherein the pressing plate includes an inclined abutting portion coming into surface contact with the clamping plane of each of the burning plates.   
     
     
         2 . The plate type burner according to  claim 1 ,
 wherein a downward stepped portion to enclose a region in which the burner ports are formed is disposed on the upper surface of each of the burning plates; and   wherein the clamping planes are formed on an outside of each of the stepped portions.
