Endotermisk reaktionsugn

摘要

An endothermic reaction furnace (102) includes one or more elongated tubes (110) defining therein an endothermic reaction flow path and a combustion flow path for providing heat to drive the endothermic reaction. The combustion flow path is arranged so that fuel and combustion air are separately heated by the heat inside the furnace (102) to significantly above their autoignition temperature before being combined in a combustion zone (116) where they mix, autoignite and burn.
