PURPOSE:To dispense with an iron shell reinforcement at the connect part in the base part of a connecting tube by specifying the ratio of the tube diameter of the connecting tube to the dome diameter of a regenerator and the ratio of the tube diameter of the connecting tube to the dome diameter of a combustion chamber, respectively. CONSTITUTION:The side wall of the dome 10 in the regenerator 1 and the side wall of the dome 11 in the combustion chamber 2 are directly connected with the connecting tube 4 without using a flexible joint to form an outer combustion type hot stove 12. In this hot stove 12, the ratio RD/TD of the tube diameter RD of the connecting tube 4 to the diameter TD of the regenerator 1 is specified to 0.24-0.60. Further, the ratio RD/ND of the tube diameter RD of the connecting tube 4 to the dome diameter ND of the combustion chamber 2 is specified to 0.44-0.60. By this method, the locally generated stresses at the base parts A, B of the connecting tube are suppressed and the iron shell reinforcements in the base parts A, B of the connecting tube are made unnecessary.
