Abstract

L'invention concerne le transfert de chaleur entre un gaz et un autre milieu, qui peut être solide, liquide ou gazeux. Du gaz est envoyé dans une zone 2 d'échange de chaleur par une entrée 4, tandis que des particules solides sont introduites par le sommet 5 de la zone et tombent librement à travers le gaz en procédant à des échanges de chaleur avec celui-ci. Les particules sont extraites de la partie inférieure 3 de la zone et peuvent être soumises à un autre transfert de chaleur, par exemple dans un lit fluidisé 12, 13 et 14. L'invention sert à la récupération de la chaleur des gaz de combustion, sans que l'échangeur de chaleur ne vienne directement en contact avec les gaz de combustion. Ceci réduit le risque de contamination ou de corrosion de l'échangeur par les gaz.The invention relates to the transfer of heat between a gas and another medium, which may be solid, liquid or gaseous. Gas is sent to a heat exchange zone 2 through an inlet 4, while solid particles are introduced through the top 5 of the zone and fall freely through the gas, exchanging heat with it. . The particles are taken out from the lower part 3 of the zone and can be subjected to another heat transfer, for example in a fluidized bed 12, 13 and 14. The invention serves for the recovery of heat from the combustion gases, without the heat exchanger coming into direct contact with the combustion gases. This reduces the risk of gas contamination or corrosion of the exchanger.
