Abstract
A non-burning cigarette holder is comprised of an upstream cylindrical section of a low heat conducting material and a downstream cylindrical section of a relatively high heat conducting material. The upstream cylindrical section has a first upstream chamber for receiving a fuel source and a second downstream chamber defining a fuel mixture chamber which is in flow communication with the first upstream chamber. The downstream cylindrical section is provided with a flame holder downstream of the chamber and a flame chamber is disposed between the flame holder and a cigarette receiving chamber adapted to receive a tobacco rod or a cigarette. The fuel source may be an ethanol-water mixture disposed within the upstream cylindrical section or the fuel source may be attached to the upstream end of the upstream cylindrical section.
