DUAL-FUEL GAS-PELLET BURNER ASSEMBLY
First Claim
1. A dual-fuel gas-pellet burner assembly, comprising:
- a cooking gas line;
a cooking gas igniter;
a motor-driven pellet auger;
a combustion air channeling section enclosing the motor-driven pellet auger and at least a section of the cooking gas line; and
a dual-fuel sectioned combustion chamber including a gas combustion section and a fire pot section,wherein the gas combustion section includes a terminal end of the cooking gas line and the cooking gas igniter disposed therein, and the fire pot section includes a terminal end of the motor-driven pellet auger disposed therein.

Abstract
Embodiments of the inventive concept provide a dual-fuel gas-pellet burner assembly. The dual-fuel gas-pellet burner assembly can include a cooking gas line, a cooking gas igniter, a motor-driven pellet auger, a combustion air channeling section enclosing the motor-driven pellet auger and at least a section of the cooking gas line, and a dual-fuel sectioned combustion chamber including a gas combustion section and a fire pot section. The gas combustion section includes a terminal end of the cooking gas line and the cooking gas igniter disposed therein. The fire pot section includes a terminal end of the motor-driven pellet auger disposed therein. The gas combustion section of the dual-fuel sectioned combustion chamber is partitioned off from the fire pot section by an internal separator wall. A control unit including a digital temperature display, a temperature dial, and a switch can receive a user selection among three different modes of operation.

14. A method for operating a dual-fuel gas-pellet burner assembly, the method comprising:
-
partitioning off a gas combustion section of a dual-fuel sectioned combustion chamber from a fire pot section of the dual-fuel sectioned combustion chamber by an internal separator wall; connecting the gas combustion section of the dual-fuel sectioned combustion chamber to the fire pot section of the dual-fuel sectioned combustion chamber via an opening in the internal separator wall; delivering, by a motor-driven pellet auger, fuel pellets to the fire pot section of the dual-fuel sectioned combustion chamber; igniting, by a cooking gas igniter disposed in the gas combustion section of the dual-fuel sectioned combustion chamber, cooking gas received from a cooking gas line within the gas combustion section that is partitioned off from the fire pot section; permitting, by the opening in the internal separator wall, the ignited cooking gas to enter the fire pot section of the of the dual-fuel sectioned combustion chamber; and combusting the fuel pellets by the ignited cooking gas. - View Dependent Claims (15, 16, 17, 18, 19)
