Abstract
(EN)
An apparatus for vaporizing a liquid and heating the vaporized liquid to an elevated temperature. The apparatus has a heat transfer wall having an outer surface for receiving heat and transferring the heat to an inner surface. A wick material is disposed so that a portion of the wick material is in contact with the inner surface and another portion is remote from the heat transfer wall. A wick support in contact with the wick material opposite the inner surface of the heat transfer wall provides structural support to the wick material and further provides a path for vaporized liquid to flow from the wick material. Vaporizable liquid is delivered to the portion of the wick material that is remote from the heat transfer wall and is allowed to migrate to the portion that is in contact with the inner surface. Heat from the inner surface converts the liquid to a vaporized liquid. Optionally, a gaseous fuel may be introduced into the wick support for pre-heating and mixing with the vaporized liquid. Vaporized liquid flows out of the wick material through the wick support and into a downstream superheater that preferably houses a heat exchange device. The heat exchange device is in thermal communication with the inner surface of the heat transfer wall for receiving and transferring heat to the vaporized liquid. The apparatus can include multiple vaporization units connected to common and/or different heat sources. Methods for making an apparatus for vaporizing a liquid and methods for vaporizing a liquid are also disclosed.

L'invention concerne un appareil destiné à vaporiser un liquide et à chauffer le liquide vaporisé jusqu'à une température élevée. L'appareil est doté d'une paroi de transfert de chaleur présentant une surface extérieure destinée à recevoir de la chaleur et à transférer la chaleur à une surface intérieure. Un matériau pour mèche est disposé de telle sorte qu'une partie du matériau pour mèche soit en contact avec la surface intérieure et qu'une autre partie soit écartée de la paroi de transfert de chaleur. Un support de mèche en contact avec le matériau pour mèche en face de la surface intérieure de la paroi de transfert de chaleur assure un support structural au matériau pour mèche et donne en outre un chemin d'écoulement du liquide vaporisé à partir du matériau pour mèche. Un liquide vaporisable est amené jusqu'à la partie du matériau pour mèche qui se trouve à l'écart de la paroi de transfert de chaleur et on le laisse migrer vers la partie qui se trouve en contact avec la surface intérieure. La chaleur provenant de la surface intérieure convertit le liquide en un liquide vaporisé. Eventuellement, un combustible gazeux peut être introduit dans le support de mèche en vue de préchauffer et de se mélanger avec le liquide vaporisé. Le liquide vaporisé s'écoule hors du matériau pour mèche à travers le support de mèche et dans un surchauffeur en aval qui contient de préférence un dispositif d'échange de chaleur. Ledit dispositif d'échange de chaleur est en communication thermique avec la surface intérieure de la paroi de transfert de chaleur afin de recevoir de la chaleur et de la transférer au liquide vaporisé. L'appareil peut comprendre des unités de vaporisation multiples reliées à des sources de chaleur communes et / ou différentes. L'invention concerne également des procédés de construction d'un appareil destiné à vaporiser un liquide et des procédés de vaporisation d'un liquide.
