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.
Claims22
A heating system comprising:
- a burner nozzle;
- and
- a burner;
- wherein the burner nozzle comprises:
- a housing defining an inlet, an outlet and an inner chamber between the inlet and the outlet;
- a movable body within the inner chamber;
- and
- a biasing member configured to regulate a positional relationship between the body and a wall of the inner chamber in response to a pressure of a fluid flow, flowing through the burner nozzle;
- wherein the positional relationship between the body and the wall of the inner chamber is configured to determine the amount of fluid flow through the burner nozzle, such that a predetermined increase in pressure of the fluid flow from an at rest position results in the movable body moving closer to the wall of the inner chamber to reduce the cross-sectional area of the flow passage between the body and the wall and correspondingly, a decrease in pressure of the fluid flow results in the movable body moving farther away from the wall of the inner chamber to increase the cross-sectional area of the flow passage between the body and the wall until the rest position is achieved.

A heating system comprising:
- a burner;
- and
- a burner nozzle comprising:
- a housing defining an inlet, an outlet and an inner chamber between the inlet and the outlet;
- a movable body within the inner chamber;
- and
- a biasing member configured to regulate a positional relationship between the body and a wall of the inner chamber in response to a pressure of a fluid flow, flowing through the burner nozzle;
- wherein in a first position of the movable body within the inner chamber, the amount of flow allowed through the burner nozzle is more than in a second position and wherein the movable body is configured such that movement between the first and second positions is controlled by the pressure of the fluid flow acting on the biasing member.
