持構造。 A tubular heat exchanger consisting of a plurality of heating tubes, each of which communicates with a water supply inlet chamber and a water supply outlet chamber at both ends through tube plates, housed in a cylindrical container-shaped body through which a heat medium flows. In the vessel, a plurality of heating tube support plates having a smaller diameter than the inner diameter of the body and disposed in the body in parallel with the tube plate, and a plurality of heating tube support plates arranged between the support plate closest to the tube plate and the tube plate; A plurality of spacing rods arranged between the rods are equally spaced apart from each other on the circumference of the support plate to form a circle having an envelope smaller in diameter than the inner diameter of the body and larger than the diameter of the support plate. The slide rods are arranged in such a manner that they extend in the longitudinal direction of the body and are fixed on the circumference of each of the support plates, and the outer circumferential surface of the slide rods and the lower part of the inner circumferential surface of the body are connected to each other. A support structure for a heating tube, characterized in that it is in line contact.
