Abstract
An endothermic reaction furnace includes one or more elongated reaction tubes 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 preferably to significantly above their autoignition temperature before being combined in a combustion zone where they mix, autoignite and burn. The fuel is introduced into the combustion zone by a plurality of tubes having outlet ends arranged to produce annular shrouds of flame around each reaction tube that are directed countercurrent to the endothermic reaction product.
