Abstract
A dual fuel heater can couple with one of two fuel sources operating at different pressures. The dual fuel heater can have a first fuel line, a second fuel line, a fluid flow controller, and a combustion chamber. The fluid flow controller can selectively permit flow of a first fuel to either the first fuel line or flow of a second fuel to the second fuel line. The first fuel line can be in communication with a first oxygen depletion sensor orifice and the second fuel line can be in communication with a second oxygen depletion sensor orifice.
Claims12
A dual fuel heater for coupling with one of two fuel sources operating at different pressures, the heater comprising:
- a first fuel line;
- a second fuel line;
- a fluid flow controller configured to selectively permit flow of a first fuel to either the first fuel line or flow of a second fuel to the second fuel line;
- and
- a combustion chamber;
- wherein the first fuel line is in communication with a first oxygen depletion sensor orifice and the second fuel line is in communication with a second oxygen depletion sensor orifice.
A dual fuel heater for coupling with one of two fuel sources operating at different pressures, the heater comprising:
- a first fuel line;
- a second fuel line;
- a third fuel line;
- a fourth fuel line;
- a fluid flow controller configured to selectively permit flow of said first fuel to the first fuel line or flow of said second fuel to the second fuel line and wherein the fluid flow controller is configured to selectively permit flow of said first fuel to the third fuel line or flow of said second fuel to the fourth fuel line;
- and
- a combustion chamber;
- wherein the first fuel line is in communication with a first oxygen depletion sensor orifice and the second fuel line is in communication with a second oxygen depletion sensor orifice;
- wherein the third fuel line is in communication with a first burner nozzle outlet and the fourth fuel line is in communication with a second burner nozzle outlet, and wherein said first burner nozzle outlet and said second burner nozzle outlet are positioned to discharge fuel into the combustion chamber.
