PURPOSE:To prevent ununiform inclination of reaction tube at high temp. due to thermal deformation by forming a produced gas manifold from a space part communicating to external part utilizing a space enclosed by an external tube of a reaction tubes and upper and lower tube plates. CONSTITUTION:When produced gas passes through a regeneration chamber 7, the sensible heat is supplied to the internal tube 3 of the reaction chamber, and the produced gas is discharged from an outlet nozzle 12 provided to the manifold 9 of the produced gas. On one hand,fuel gas introduced from a fuel inlet nozzle 14 and combustion air introduced from a combustion air inlet nozzle 15 are introduced into the combustion chamber 13 formed as a space below the reactor vessel 1, and the gases are burnt in the combustion chamber 13 by the burner nozzle 16. The combustion gas at high temp. generated by the combustion in the combustion chamber 13 is led to a combustion gas passage 17 where it heats the external tube 2 of the reaction tube, then discharged from a discharging nozzle 18 of the combustion gas. |
