20230023054 · 2023-01-26 ·

The invention relates to a reformer furnace for catalytic reforming of a carbon-containing input material with steam. The reformer furnace has a steel construction which serves as a framework for a refractory lining and for the fastening of burners, reformer tubes and supply and discharge lines. The burners and reformer tubes are arranged in rows, parallel to one another and in alternating fashion. The steel construction includes a plurality of main carrier units, wherein each main carrier unit has at least two vertically extending supports and a horizontally extending main carrier which connects the supports. This type of steel construction makes it possible to achieve uniform spacing of the reformer tubes and burners over the entire reformer furnace. This results in advantages in terms of the maximum operating temperature of the reformer tubes, thereby extending their service life.
