方法を調整するのが困難である。Conventional reforming equipment is configured as described above, with one burner (7 burners) installed in the center of the equipment, which increases the combustion space αυ and increases the outer diameter of the entire equipment. In addition, fireproof material (4) was used to prevent the flame from coming into direct contact with the filler and to create a combustion gas passage.
was needed. Furthermore, when the combustion gas that has passed through the flame-extinguishing rectifying grid (9) passes through the filler (to), the flow rate of the combustion gas flowing near each reaction tube may become uneven depending on the filling condition of the filler Q19. There is. Therefore,
Each reaction tube is not necessarily heated uniformly. Furthermore, it is difficult to adjust the method of filling the filler so that the gas flows uniformly throughout the gas flow path.
