## Abstract

An improved chimney starter having a cylindrical housing having an outer wall and inner wall defining a chamber, the chamber configured to hold charcoal. A series of spiral heat exchange chambers contained within the cylindrical housing and an air intake port provided on a portion of the cylindrical housing, wherein the air intake port is connected to the series of spiral heat exchange chambers. A base configured to retain a fire starter configured to ignite and burn the charcoal. Advantageously, a fan blower is configured to be positioned in the air intake port such that blown air is configured to be directed through the series of spiral heat exchange chambers, wherein the directed air accelerates the burning of the charcoal.

## Claims

### Claim 1

An improved chimney starter comprising:
a cylindrical housing having an outer wall and inner wall defining a chamber, the chamber configured to hold charcoal;
a series of spiral heat exchange chambers contained within the cylindrical housing; a top rim configured to connect the outer wall to the inner wall and enclose the series of spiral heat exchange chambers;
an air intake port provided on a top portion of the cylindrical housing, wherein the air intake port is connected to the series of spiral heat exchange chambers;
a base configured to retain a fire starter configured to ignite and burn the charcoal;
a fan blower configured to be positioned in the air intake port such that blown air is configured to be directed through the series of spiral heat exchange chambers, wherein the directed air accelerates the burning of the charcoal;
an airflow splitter positioned within the air intake port configured to split the directed air into multiple streams through at least two different spiral heat exchanger chambers of the series of spiral heat exchange chambers helping the charcoal to burn evenly; and,
wherein the inner wall of the cylindrical housing includes spiral blades configured to assist the directed air around the inner wall of the cylindrical housing chamber from top to bottom.

### Claim 2 (depends on 1)

The improved chimney starter of claim 1, wherein the base is removable.

### Claim 3 (depends on 2)

The improved chimney starter of claim 2, wherein the cylindrical housing includes a plurality of air vents positioned at a bottom portion of the cylindrical housing, and the removable base is configured to seal off the plurality of air vents.

### Claim 4 (depends on 3)

The improved chimney starter of claim 3, wherein the plurality of air vents is configured to encircle the entirety of the cylindrical housing.

### Claim 5 (depends on 1)

The improved chimney starter of claim 1, further comprising a number of air flow deflectors on a top surface of the base.

### Claim 6 (depends on 1)

The improved chimney starter of claim 1, further comprising a handle attached to the outer wall of the housing, the handle enabling a user to handle the chimney starter.

### Claim 7 (depends on 1)

The improved chimney starter of claim 1, wherein the fan blower is wireless.

### Claim 8 (depends on 1)

The improved chimney starter of claim 1, wherein the charcoal is placed on a grate inside the cylindrical chamber, wherein the grate is above the base.
