Definitions

  • This invention relates to gas fires.
  • the plaque is suitably of ceramic foam of the kind disclosed in published PCT Specification WO 84/01992, or other material showing cross-porosity allowing some air to be entrained into the secondary gas stream.
  • a section of a fire on the above principle is shown in the accompanying drawing where within a metal casing 10 a lower body or box of conventional alumina-silica ceramic 9 defines a gas-air plenum 1 fed with gas from a jet 8a through an air entrainment venturi 4 in known manner.
  • the jet has a 1.92 mm diameter orifice and operates at 17.5 cm (water gauge) pressure using natural gas, the venturi being 12 cm long with a 15 mm throat and 20 mm entry.
  • a ceramic foam plaque 2 45 cm across is shaped at the surface to represent artificial solid fuel 7 and closes the top of the box.
  • the solid fuel 7 coloured and rendered substantially impermeable by sprayed- on clay/water slip coloured with black and coral underglaze pottery colours and optionally glazed in known manner, forms non-glowing areas between which at 5 are glowing areas simulating the bed of a solid fuel fire.
  • luminous gas flames 6 play. No special apertures through the plaque are used, and the construction gives sufficient air for combustion in a luminous flame but without sooting.
  • the gas feeds are behind or rather below the fuel, which may be formed in one piece with the plaque as shown or if desired as separate members placed on a suitably shaped plaque.

Claims (2)

1. Foyer à feu de gaz comprenant un élément rayonnant dont la surface porte un combustible solide simulé ou est formé en combustible solide simulé, caractérisé en ce que l'effet chauffant principal du feu est produit par la combustion d'un mélange de gaz/air passant par le corps d'un élément poreux (2) et brûlant à la surface de l'élément afin de chauffer ce dernier jusqu'à l'incandescence, mais en ce qu'un conduit d'alimentation en gas secondaire (8b) est disposé de sorte qu'il passe par la matière poreuse du corps lui-même et brûle sous forme de flammes individuelles (6) à côté du combustible simulé (7), dont il simule la combustion, et produit un effet chauffant auxiliaire.
2. Foyer à feu de gaz selon la revendication 1, dans lequel la plaque consiste en mousse céramique ou en autre matière d'une porosité mutuelle permettant l'aspiration d'une certaine quantité d'air dans le conduit de gas secondaire.
