２図に示す。 Two or more heat exchanger tubes 7 wound into a coil are inserted concentrically into one heat exchanger. For example, in the illustrated embodiment, flexible tubular heat exchanger tubes with the same diameter are fitted with different coil diameters so that they fit concentrically with each other, three times inside and outside, but this multiple fitting between the inside and outside is generally is used in multiple layers. The heat exchanger tubes 7 of each layer are supported in shape by support columns 8 installed substantially parallel to the heat storage cylinder between support plates that protrude outward from the outer periphery of the heat storage cylinder. The struts 8 are inserted into the inner circumferential side of one layer of coiled heat exchanger tubes 7 at approximately equal intervals, for example, every 90 degrees, and both ends of the struts are screwed to the support plates 5 and 6 via nuts N. Therefore, the heat exchanger tube 7 is suspended or skewered supported by the support 8 which penetrates the tube so as to be in contact with the inner periphery thereof. Further, the second layer of coiled heat exchanger tubes 7 and the third and fourth layers are formed in the same manner. Then, a second layer of coiled heat exchanger tubes is fitted on the outer periphery of the first layer of coiled heat exchanger tubes 7, and then a third layer and a fourth layer are fitted on the outer periphery of the second layer. This state is shown in FIGS. 1 and 2. .

れる。 Furthermore, spacers 91, 92, 93, . . . 9n are provided at both ends of the coiled heat exchanger tubes in each layer.
For example, a spacer 91 inserted between the first and second rings from the terminal end of the first layer coiled heat exchanger tube presses the outermost end surface of the second layer coiled heat exchanger tube, causing the second layer coiled heat exchanger tube to accidentally press the outermost end surface of the second layer coiled heat exchanger tube. Hold the coil pitch firmly so that it does not change. Similarly, the spacer 92 is inserted between the second and third coiled heat transfer tubes in the first layer, between the first and second coiled heat transfer tubes in the second layer, and the spacer 92 is inserted between the first and second coiled heat transfer tubes in the third layer. It is arranged so as to be in contact with the outer end surface. Similarly, spacers 93 and subsequent parts are also provided to fix the coil pitches of the coiled heat exchanger tubes in each layer. Note that the spacers 91, 92, . . . are also made of thin strip-shaped metal plates, and are supported by the supports 8 by penetrating through the supports 8 of each layer.
In this way, the multilayer coiled heat exchanger tube is integrally formed with the support plate, struts, and spacers, and is inserted into the casing 1, and the ends of the struts are connected to the head caps 2 and 3. be adhered to.
なお各層コイル状伝熱管はその一端から給水

よい。 What is shown in FIG. 4 is an explanatory view in which a gas body passes between the heat exchanger tubes wound into a coil. The coiled heat transfer tube of the present invention is wound so that each coil (ring) is in contact with each other, but even in this case, the adjacent coil rings do not contact each other so as to completely block gas flow. The contact points change in the direction of the outer circumference of the rings, and a gap is provided between adjacent coil rings, allowing the gas to freely flow through this gap. Therefore, in order to provide a gap that allows gas to flow between adjacent coil rings, when the protrusions are formed in a spiral shape, it is sufficient to simply wind the spiral tube in a spiral shape.

According to the present invention, the heat exchanger tube disposed in the gas flow passage is a flexible coil type, so even if the heat exchanger tube is tightly wound in a spiral, the gap for gas flow is passed through the groove of the flexible tube. gas can be secured, gas is divided in the radial direction, manufacturing and assembly are simple, costs can be significantly reduced, and maintenance such as cleaning can be easily performed. Also, since a flexible tube is used, heat transfer performance is improved.
It has advantages such as 27 to 37% improvement.
