Abstract
One or more techniques and/or systems are disclosed for a portable heating device comprising a combustion-powered heater, a regulator, and an air quality detector, such as an oxygen depletion sensor. The combustion-powered heater may be supplied by an associated fuel source and may comprise a combustion region comprising a catalytic surface. The regulator may be adapted for fluid communication with the associated fuel source. The air quality detector may comprise a burner and a temperature detector. The burner may be in fluid communication with the regulator and may be adapted to combust fuel form the regulator with air to produce a flame. The temperature detector may be adapted to detect the temperature of the flame and may be adapted to selectively render the combustion-powered heater non-functional.
Claims20
A portable heating device comprising:
- a catalytic surface configured to generate heat from a catalyzed reaction when exposed to a heating fuel and oxygen;
- and
- a fuel supply valve configured to mitigate a supply of the heating fuel to the catalytic surface when the valve is disposed in a closed position, the valve disposed in a closed position in absence of a signal indicative of a desirable atmosphere from an air quality detector, the air quality detector configured to transmit the signal indicative of the desirable atmosphere merely if a desired atmosphere is detected by the air quality detector, and the air quality detector comprising a temperature sensor configured to detect a temperature of a detector flame.
A portable heater, comprising:
- a catalytic heat generation component fluidly coupled to a fuel source;
- an air quality detector configured to selectively mitigate a flow of fuel between the fuel source and the catalytic heating component when a non-desired atmosphere is detected, the air quality detector comprising:
- a burner, in fluid communication with the fuel source, and configured generate a detector flame, and
- a temperature sensor, operably engaged with the detector flame, and configured to detect the temperature of the detector flame.
A heating device, comprising:
- a catalytic heater fluidly coupled with an associated fuel source, the catalytic heater comprising a catalytic heating surface, comprising a catalyst and a substrate, the catalytic heater configured to perform one or more of:
- generate heat in the presence of oxygen from the atmosphere and fuel;
- and
- release one or more combustion products into the atmosphere;
- a valve, operably engaged between the catalytic heat heating surface and the fuel source, the valve configured to be disposed in a closed position in absence of a signal indicative of a desired atmosphere;
- and
- an oxygen depletion sensor (ODS) configured to detect the desired atmosphere and relay the signal indicative of a desired atmosphere to the valve, resulting in the valve being disposed in an open position, the ODS comprising,
- an ODS burner, fluidly coupled with the fuel source, the ODS burner configured to produce an ODS flame;
- and
- an ODS detector configured to detect a first property of the ODS flame, the first property of the ODS flame is indicative of a depleted oxygen content when
- the atmosphere comprises a carbon dioxide amount of more than 5000 PPM.
