A chimney starter or charcoal chimney is a device for igniting
charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, ca ...

s. It consists of a metal tube with a grate to hold charcoal. A lighting cone is a similar, conical, device placed over an existing grate. The tube is typically cylindrical, but may also have other cross-sections.

History
A 1910 British design for a cylindrical metal portable stove
A portable stove is a cooking stove specially designed to be portable and lightweight, used in camping (recreation), camping, picnicking, backpacking (wilderness), backpacking, or other use in remote locations where an easily transportable means ...
is described as "also applicable for use as a Fire Lighter" and describes the use of paper kindling below a conical grate, with wood or coal above it.
A 1917 design closely resembles a modern chimney starter: a metal cylinder with a raised grate and air holes below the grate. However, it is not described as a fire starter, but as a "camp stove".
Home-made versions in the 1950s, called kindle cans, were often made from metal coffee, fruit juice, or motor oil cans with ventilation holes punched with a can opener, and did not have a grate. They often did not have handles, and needed to be handled with tongs.
Various kinds of chimney starter have been patented over the years.
Design considerations
Chimney starters essentially work by increasing the draft
Draft, the draft, or draught may refer to:
Watercraft dimensions
* Draft (hull), the distance from waterline to keel of a vessel
* Draft (sail), degree of curvature in a sail
* Air draft, distance from waterline to the highest point on a v ...

to the coals. Taller starters are more effective than shorter ones. In empirical studies of lighting cones for Haitian charcoal stoves (which are placed ''over'' a grate rather than having an integrated grate), the ignition time and charcoal consumption were halved compared to lighting on a shallow bed grate, and carbon monoxide

production was reduced by 40%. The cone also protected the charcoal from the wind, and helped direct the smoke away from users.
Using a chimney starter
The chimney starter is used by placing kindling—typically paper—under the grate and charcoal over it. When the kindling is lit, it ignites the charcoal and creates a draft. Since the coals are held together, radiation

heats coals higher in the stack. Once all the charcoal is burning (glowing red on the bottom and ashed over on the top), the chimney is lifted by its handle and the burning charcoal dumped into the grill. Dry newspaper is a popular and affordable chimney start but can cause increased smoke output during the process.
If some burning charcoal remains in the chimney, adding new charcoal will quickly ignite it.
Cooking
One can also cook directly over the chimney starter with an additional top grate. This provides high-intensity heat for fast searing
Searing or pan searing is a technique used in grilling, baking, braising, roasting, sautéing, and the like, in which the surface of the food (usually meat such as beef, poultry, pork
