Abstract
A combustion plate for use in a totally aerated combustion burner has a ceramic plate body with a multiplicity of flame holes formed therein for ejecting a premixed gas. The plate body is provided, in a lattice shape, with non-flame-hole portions having no flame holes therein. Each of such regions of the plate body as are enclosed by the non-flame-hole portions constitutes a collective flame-hole portion having formed therein a plurality of flame holes. It is so arranged that flame lifting can be effectively prevented in the flame holes on the periphery of the collective flame-hole portions. Along each of such sides of the non-flame-hole portions as are adjacent to each of the collective flame-hole portions, outside flame holes are formed at a predetermined spacing therebetween in a longitudinal direction of the non-flame-hole portions. This predetermined spacing is greater than a spacing, in the longitudinal direction of the non-flame-hole portion.
