Abstract

PURPOSE: To enable the removal of adhered substances by the combustion of cracked gas in a double tube type heat exchanger wherein high temperature steam is generated from the cracked gas by providing a heat insulative cylinder around double tubes which communicate between boiling chambers of thin plate being properly reinforced.
CONSTITUTION: The high temperature cracked gas 59 flows from an entrance chamber 31 through an inner tube and discharged from an outlet chamber 33. On the other hand, supply water enters the boiling chamber on the entrance side 32 which is constituted by thin tube plates 45, 45 reinforced by a bar stay 48, ascends along an annular part of the double tubes 53 while it is vaporizing, and comes out of the boiling chamber on the outlet side 54 of the same constructon. In order to burn and remove the attachment to the inner tube 56, the water is all discharged and a high temperature air is fed through a gas inlet 40 to burn the attachment. In this case, the provision of the heat insulative cylinder around the double tubes 35, which contributes to decreasing the temperature difference between the outer and inner tubes, eliminates a possibility of damaging the device due to the thermal stress together with the tube plates 45 and 51 being thin.
