A combustion-powered heater may comprise a combustion site adapted to power said heater. A target component may be engaged with the combustion site. A transducer may be adapted to measure the temperature of the target component and adapted to shut-down said combustion-powered heater in response to a temperature measurement of less than a temperature limit.

Abstract: Provided is a portable heating device comprising a combustion-powered heater, a regulator, and 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 oxygen depletion sensor 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.

Abstract: A vertically storable combustion heater having a fuel tank having a generally-cylindrical passage formed in the fuel-tank housing through which an axle extends to support one or more wheels; a heating conduit that is coupled to the fuel tank and includes an outermost shell that is substantially concentric with an inner shell that has a smaller diameter than the outermost shell; a control panel that is connected to the combustion heater to interface with an operator and allows the operator to input instructions governing the operation of the combustion heater; a frame that at least partially encases the heating conduit and fuel tank; a hose having a return curve and nozzle; and a combustion chamber that is defined by the interior periphery of the inner shell.

A housing may comprise an air inlet and may define an interior region. A burner assembly may comprise a fuel valve adapted to control communication between the burner assembly and the associated fuel source, a venturi for mixing air and fuel into a fuel-air mixture, a combustion region adapted for the combustion of the air-fuel mixture to produce combustion products and heat.

Abstract: A portable radiant heater supplied by an associated fuel source comprises a housing having a handle for transporting the heater. A plenum in the housing receives fuel from the associated fuel source and mixes the fuel with air. A burner assembly includes a radiant surface that communicates with the plenum. A regulator limits the pressure of the associated propane source to approximately eleven inches water column, and an oxygen depletion system associated with the burner assembly automatically shuts off the heater at a predetermined oxygen content. A tank fitting with a position that can be adjusted relative to the regulator facilitates the installation of the associated fuel source to the heater.
