<p>The invention relates to a method and to an apparatus for providing a steam flow as constantly as possible from an alkane dehydrogenation, wherein the method is performed by way of passing a hydrocarbon-containing gas through reactor tubes which can be filled with a catalyst, and wherein the reactor tubes closed towards the outside are guided through a heating chamber which can be heated by burners, and wherein the catalyst for the reaction is regenerated cyclically, wherein the reaction is endothermic and the catalyst regeneration is not endothermic, and wherein the main burners are reduced in power during the regeneration of the catalyst, wherein auxiliary burners are positioned at the inlet of the flue gas channel for the further generation of hot flue gas which continue producing hot flue gas during the regeneration of the catalyst, wherein said hot flue gas is used to generate steam as constantly as possible from the waste heat of the process.</p> |
