Patent ID: 8479440

Claim:
An apparatus for use in killing pests in an affected area, comprising: a fuel source comprising a fuel tank; a first air inlet configured to receive a first air flow from an affected area; a second air inlet configured to receive a second air flow from an unaffected area; a premix system operable to generate an air-fuel mixture by mixing a fuel flow received from the fuel source with the second air flow received from the second air inlet; a burner operable to generate combustion air by combusting the air-fuel mixture, the combustion air being mixed with the first air flow to generate a heated air flow to be discharged into the affected area, the burner being configured such that the flame resulting from the combustion of the air-fuel mixture is shielded from the first air flow; a thermostat positioned in the first air inlet, the thermostat operable to measure an air temperature at the first inlet; and a controller configured to communicate with the thermostat, the controller operable to cause a change in the heated air flow being discharged into the affected area based on the measurement of the air temperature at the first air inlet; wherein the fuel tank, the premix system, the burner, the thermostat, and the controller are housed in a moveable cabinet for positioning in the affected area.
