Abstract:
1. A combined water and fire display system comprising: a reservoir containing a volume of water; at least one water source associated with said reservoir; at least one power source associated with said system; at least one source of flammable gas associated with said system; and a unit for emitting flammable gas, the unit being at least partially submerged within said volume of water, said unit comprising: (a) a first gas line for directing flammable gas from said at least one source of flammable gas to one or more locations beneath a surface of the volume of water; (b) at least one water level sensor, wherein said water level sensor is operable to selectively transmit water from said water source to said reservoir upon the detection of an absence of a predetermined quantity of water; (c) a recirculation drain; (d) an overflow drain; (e) a pilot light positioned above said volume of water for igniting said flammable gas; and a toroidal member provided around said unit and said pilot light at a surface of said volume of water, said toroidal member extending above and below the surface of said volume of water and adapted to promote combustion of gas substantially proximate to said pilot light by preventing propagation of gas radially outward of the toroidal member.
