Abstract
A furnace system includes a heat exchanger and a burner assembly including a burner enclosure fluidly coupled to the heat exchanger. The burner assembly is configured to receive a fluid, ignite the fluid to produce combustion byproducts, and direct the combustion byproducts to the heat exchanger. The furnace system also includes a pressure sensor configured to detect a pressure within the burner enclosure. The furnace system is configured to operate based on the pressure detected by the pressure sensor.
Claims20
A furnace system, comprising:
- a heat exchanger;
- a burner assembly comprising a burner enclosure fluidly coupled to the heat exchanger, wherein the burner enclosure is configured to receive a fluid, ignite the fluid to produce combustion byproducts, and direct the combustion byproducts to the heat exchanger;
- and
- a pressure sensor configured to detect a pressure within the burner enclosure, wherein the furnace system is configured to operate based on the pressure detected by the pressure sensor.
A furnace system, comprising:
- a burner enclosure configured to receive a fuel/oxidizer mixture and ignite the fuel/oxidizer mixture to produce combustion byproducts;
- and
- a pressure sensor disposed within the burner enclosure, wherein the pressure sensor is configured to detect a pressure within the burner enclosure, and the pressure sensor is configured to cause interruption of a flow of electrical power to the furnace system to suspend operation of the furnace system in response to the pressure comprising a vacuum that exceeds a threshold negative pressure.
A burner assembly of a furnace system, the burner assembly comprising:
- a burner enclosure comprising an internal volume, wherein the burner enclosure is configured to receive a fuel and ignite the fuel to produce combustion byproducts;
- and
- a pressure switch fluidly coupled to the internal volume, wherein the pressure switch is configured to transition between a closed configuration and an open configuration, the closed configuration enables flow of electrical power to the furnace system, the open configuration interrupts the flow of electrical power to the furnace system, and the pressure switch is configured to adjust to the open configuration in response to a vacuum within the burner enclosure exceeding a threshold pressure.
