Abstract
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.
