<p>A heat pipe and a method for operating a heat pipe of said type are provided, which heat pipe remains active over a relatively long period of time in particular when used in pressurized gasification atmosphere, that is to say in a hydrogen-rich environment. Also specified is a heat pipe reformer having a heat pipe of said type. By providing a hydrogen extractor in the region of the heat-dissipating end of the heat pipe, the hydrogen which has penetrated into the heat pipe and accumulated there is conducted out of the heat pipe again, such that the heat-exchanging capacity of the heat pipe is maintained. The hydrogen extractor generates a hydrogen concentration gradient or a hydrogen partial pressure gradient between the interior and the exterior of the pipe casing, such that hydrogen which has penetrated into the interior of the heat pipe is diffused into the hydrogen extractor and can be extracted from there. A hydrogen concentration gradient or hydrogen partial pressure gradient is also formed between the atmosphere surrounding the heat pipe, for example the atmosphere in a reforming fluidized-bed gasification chamber, and the hydrogen extractor, such that hydrogen from the surrounding atmosphere is also diffused into the hydrogen extractor and extracted from there.</p> |
