Abstract
Water on fire appearing water displays characterized by a burning fuel/air mixture entrained in a stream of water. The display uses a self entraining nozzle disposed at a proper level in a body of water, with a source of flammable gas provided a flow of gas to the lower pressure portion of the air entraining region of the nozzle and with the proper flow rate to obtain a combustible mixture of fuel/air entrained in the air stream. Coordinated variation of the water and gas flow under computer control provided a dynamic display while maintaining the flame throughout the variations. Other features are disclosed.
