ABSTRACT:
A furnace is provided having at least two regenerator beds for heat recovery. While a first bed is being heated by hot flue gases produced by combusting a fuel and an oxidant in the furnace, a second bed, heated during a previous cycle, is cooled through carrying out an endothermic chemical reaction therein, for example the reforming reaction of a hydrocarbon with water vapor and carbon dioxide and/or the dissociation of a hydrocarbon. Once the second bed is cooled by the endothermic reaction, the hot flue gases are redirected to it while the first bed, now hot, is used for carrying out the endothermic chemical reaction. Thereafter the cycle is repeated.
