Abstract

Disclosed is an induction burner ignition system that implements an induction burner located external to the fire pot. The induction burner can be controlled by a controller to start and stop according to a predetermined heating algorithm, and can further provide heat via heat sinks in contact with the induction burner. Because the induction burner is located external to the fire pot, it is easily repairable or replaceable and avoids the harmful atmosphere of the fire pot. The induction burner also provides more uniform heating than conventional hot rod technology to improve the pellet heating process.

Claims (19)

1. An induction furnace system comprising:

a fire pot having a lower-most surface;

an auger that provides pellets to the fire pot for heating therein; and

an induction burner located under the lower-most surface so as to cause at least the lower-most surface of the fire pot to heat via induction heating, to thereby heat the pellets according to a control of a controller; and

a heat sink spaced from the fire pot and interacting with the induction burner so as to cause heat to be emitted via induction heating,

wherein the induction burner is spaced from an inside of the fire pot.

2. The induction furnace system of claim 1 , further comprising holes defined in the fire pot and allowing ventilation therethrough.

3. The induction furnace system of claim 1 , wherein the auger includes internal fighting that rotates iso as to deliver the pellets.

4. The induction furnace system of, wherein the induction burner includes a central burner for causing the fire pot to heat, and an auxiliary burner for causing the heat sink to heat via induction heating.

5. The induction furnace of claim 4 , wherein the auxiliary burner is independently controllable from the induction burner to cause the heat sink to heat.

6. The induction furnace of claim 4 , further comprising a sensor coupled to the controller and causing the controller to allow current to flow to at least one of the induction burner and the auxiliary burner based on an output of the sensor to the controller.

7. An induction furnace system comprising:

a fire pot having a bottom surface;

an auger that provides pellets to the fire pot for heating therein; and

an induction burner that causes at least the bottom surface of the fire pot to heat via induction heating, to thereby heat the pellets according to a control of a controller; and

a heat sink spaced from the fire pot and interacting with the induction burner so as to cause heat to be emitted via induction heating,

wherein the induction burner is spaced from an inside of the fire pot.

8. The induction furnace system of claim 7 , wherein the induction burner includes a central burner for causing the fire pot to heat, and an auxiliary burner for causing the heat sink to heat via induction heating.

9. The induction furnace of claim 8 , further comprising a sensor coupled to the controller and causing the controller to allow current to flow to at least one of the induction burner and the auxiliary burner based on an output of the sensor to the controller.
