Abstract

PURPOSE: To remove the leakage from a heating tube, and improve the maintainability of an orifice, and make the whole heating tube compact, by welding an inlet header and the heating pipe together with each other, and possessing an inner tube having an orifice within the inlet header of the heating tube. CONSTITUTION: Heating tubes 3 are attached at equal intervals to an inlet header 4 by a heating tube mounting tube block 42. On the other hand, an orifice-arranged inner tube 40 is inserted and attached to an inlet header 4 from the side of the terminal of an inlet header. The orifice-arranged inner tube 40 is pushed in to the position of a cylindrical header 44 attached by welding to the inlet part of the inlet header 4. Moreover, the orifice-arranged inner tube 40 is provided with a key 41 for performing the positioning in circumferential direction at insertion and preventing the orifice-arranged inner tube 40 from turning during operation of a boiler The orifice-arranged inner tube 40 performs the positioning in longitudinal direction by the closing flange 45 at the terminal of the inlet header 4.
