Abstract
Abstract An axial flow delayed combustion furnace or reaction tower for synthesis gas production for pressures greater than 10 atm., and temperatures greater than 700* C., is provided with an inner thermal lining, an arch for supporting the catalyst, the arch being of ring shape and such that a stack is disposed at the center thereof through which the gas-conducting pipe extends. The lower end of the gas pipe is mounted in a reinforced collar on the floor of the reaction tower, and is connected to the tower floor through a sleeve-shaped expansion part.
