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.
Claims17
A heating system comprising:
- a burner;
- and
- a burner nozzle comprising:
- a housing defining an inlet, a first outlet, a second outlet, and an inner chamber between the inlet and the first and second outlets;
- a movable body within the inner chamber;
- and
- a biasing member configured to regulate the position of the movable body within the inner chamber in response to a pressure of a fluid flow, flowing through the burner nozzle;
- wherein in a second position of the movable body within the inner chamber, the second outlet being closed by the movable body and the amount of flow allowed through the burner nozzle is less than in a first 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.
5 more elements
A heating system comprising:
- a burner;
- a nozzle comprising:
- a nozzle housing;
- an inlet;
- at least two outlets;
- a valve comprising
- a valve body within the nozzle housing and between the inlet and the at least two outlets;
- and
- a biasing member wherein the valve and biasing member are configured such that fluid flow of a predetermined pressure acts on the valve body to at least one of 1) open, and 2) close the valve body within the nozzle housing to control fluid flow through the nozzle, wherein independent of the position of the valve body, the nozzle being configured such that at least one of the at least two outlets remains open.
