Open fire display apparatus

Abstract

A fire display apparatus comprises a structural base plate supported in a horizontal attitude within a clay, or other fire resistant bowl. The base plate supports an annular burner tube on a outer, upwardly facing surface, the burner tube providing outwardly directed plural burner apertures adapted for directing flames in a peripheral, horizontal, outward direction. The base plate also supports a burner fence positioned in spaced-apart relationship with the burner apertures and adapted for directing the flames in an upward direction away from the outer face of the base plate. A rim fence ring is positioned outward of the burner fence and is adapted for reflecting heat inwardly. Burner gas is supplied to the space between the bowl interior and the underside of the base plate. Here, gas valves and a flame sensor provide automated flame monitoring and control.

What is claimed is:  
     
         1 . A fire display apparatus comprising: a base plate supported in a horizontal attitude within a bowl, the base plate supporting: (i) an annular burner tube on a outer face of the base plate, the burner tube providing outwardly directed plural burner apertures adapted for directing flames in a peripheral, horizontal, outward direction; (ii) a burner fence positioned in spaced-apart relationship with the burner apertures and adapted for directing the flames in an upward direction away from the outer face of the base plate; and (iii) a rim fence ring positioned outward of the burner fence and adapted for reflecting heat inwardly.  
     
     
         2 . The apparatus of  claim 1  wherein the base plate provides plural peripheral drain and vent cutouts and the bowl provides at least one drain hole.  
     
     
         3 . The apparatus of  claim 1  wherein the base plate provides a subplate mounted in spaced apart relationship onto an inner face of the base plate.  
     
     
         4 . The apparatus of  claim 1  further comprising a gas supply manifold mounted on the subplate and adapted for gas delivery to a flame ignitor pilot through a pilot gas flow adjusting valve, and to the annular burner tube through a burner gas flow adjusting valve.  
     
     
         5 . The apparatus of  claim 4  further comprising a flame safety module engaged for control with a solenoid valve adapted for opening a gas supply line to the burner gas flow adjusting valve.  
     
     
         6 . The apparatus of  claim 5  further comprising a flame monitor sensor adapted for shutting the solenoid valve when a flame signal is lost.  
     
     
         7 . The apparatus of  claim 1  further comprising a reflector plate mounted medially relative to the annular burner tube.
