Abstract
Official abstract text for this publication.
A combustion plate is for use in a totally aerated combustion burner in which a plate main body made of ceramic has formed therein a multiplicity of flame holes for ejecting a premixed gas. The plate main body is provided, in a lattice shape, with non-flame-hole sections free of flame holes. Each of those sections of the plate main body which are enclosed by the non-flame-hole sections constitutes a collective flame-hole section having formed therein in a crowded manner a plurality of flame holes. Flame holes formed in those peripheral portions of the collective flame-hole sections which are adjacent to the non-flame-hole sections are smaller in diameter than the diameter of the flame holes formed in those portions of the collective flame-hole sections which are inner than the peripheral portions.
First claim
Opening claim text (preview).
What is claimed is: 1. A combustion plate for use in a totally aerated combustion burner in which a plate main body made of ceramic has formed therein a multiplicity of flame holes for ejecting a premixed gas, wherein the plate main body is provided, in a lattice shape, with non-flame-hole sections free of flame holes, each of those sections of the plate main body which are enclosed by the non-flame-hole sections constituting a collective flame-hole section having formed therein in a crowded manner a plurality of flame holes, characterized in that flame holes formed in those peripheral portions of the collective flame-hole sections which are adjacent to the non-flame-hole sections are smaller in diameter than the diameter of the flame holes formed in those portions of the collective flame-hole sections which are inner than the peripheral portions; wherein the flame holes formed in each of the side portions of the non-flame-hole sections are also smaller in diameter than the diameter of those flame holes formed in those portions of the collective flame-hole sections which are inner than the peripheral portions. 2. The combustion plate according to claim 1 , wherein flame holes are formed in each of those side portions of the non-flame-hole sections which are adjacent to the respective collective flame-hole sections, the flame holes being formed at a predetermined spacing from one another in a longitudinal direction of the non-flame-hole sections, and wherein the predetermined spacing is set larger than the spacing from one another of the flame holes formed in the collective flame-hole sections as seen in a direction parallel to the longitudinal direction of the non-flame-hole sections.
