Abstract
A heating system can include certain pressure sensitive features. These features can be configured to change from a first position to a second position based on a pressure of a fuel flowing into the feature. These features can include, fuel selector valves, pressure regulators, burner nozzles, and oxygen depletion sensor nozzles, among other features.
Claims10
A dual fuel oxygen depletion sensor comprising:
- a housing having a single inlet and a single outlet, and having a first fluid flow path and a second fluid flow path through the housing between the inlet and the outlet;
- a first air intake;
- a second air intake;
- a first injector within the housing and defining part of the first fluid flow path, the first injector comprising a first orifice, the first orifice configured to direct a first fuel from the inlet and towards the outlet while drawing air into the housing through the first air intake;
- a second injector within the housing and defining part of the second fluid flow path, the second injector comprising a second orifice, the second orifice configured to direct a second fuel from the inlet and towards the outlet while drawing air into the housing through the second air intake, wherein the first fuel is at a first pressure different from a second pressure of the second fuel;
- a first valve within the housing and defining part of the first fluid flow path, the first valve configured to control a flow of the first fuel to the first injector;
- and
- a second valve within the housing and defining part of the second fluid flow path, the second valve configured to control a flow of the second fuel to the second injector.
