Abstract
Certain embodiments of a nozzle are configured to dispense a first gas, liquid, or combination thereof at a first pressure in a first mode of operation and dispense a second gas, liquid, or combination thereof at a second pressure in a second mode of operation. In some embodiments, the nozzle is integrated in a heat-producing device, such as, for example, a heater, a fireplace, or a stove. In some embodiments, the heat-producing device including the nozzle can operate with a first combustible fuel at a first pressure, or alternatively, can operate with a second combustible fuel at a second pressure. In some embodiments, the nozzle is used in applications other than heat-producing devices.
Claims13
A heater configured to operate with either a first fuel at a first pressure or a second fuel at a second pressure, the heater comprising:
- a first oxygen depletion sensor nozzle line defining a passageway;
- a second oxygen depletion sensor line defining a passageway;
- and
- a first oxygen depletion sensor nozzle communicating with a fluid flow controller;
- a second oxygen depletion sensor nozzle communicating with said fluid flow controller;
- a first heater nozzle line defining a passageway;
- a second heater nozzle line defining a passageway;
- and
- a heater nozzle comprising:
- a first cavity in fluid communication with the first heater nozzle line, the first cavity having an input end configured to couple with the first heater nozzle line and an output end configured to dispense fuel at the first pressure, wherein the first cavity decreases in size toward the output end thereof;
- and
- a second cavity in fluid communication with the second heater nozzle line, the second cavity having an input end configured to couple with the second heater nozzle line and an output end configured to dispense fuel at the second pressure, wherein the second cavity decreases in size toward the output end thereof, further comprising:
- said fluid flow controller configured (1) to permit the flow of fuel to the first cavity and to direct a first gas to said first oxygen depletion sensor nozzle when the controller is in a first position and (2) to prevent the flow of fuel to the first cavity, to permit the flow of fuel to the second cavity and to direct a second gas to said second oxygen depletion sensor nozzle when the controller is in a second position.
