Combustion device

摘要

A fuel gas combustor which utilizes thermal assisted expansion and mixing of the fuel gas and a combustion supporting gas for more complete combustion and greater heat output. A heat transfer device provides thermal feedback from the flame to the gas expansion zone. The invention is especially useful in hand-held torch tips. In a specific embodiment, the heat transfer device include a heat conducting element, at least the intermediate portion of which is rod shaped and sheathed in a non-conducting envelope.
