By arranging heat transfer tubes, the exhaust gas boiler which increased the heat recovery amount is proposed by making effective use of a heat transfer surface.

Republic of Korea Patent Publication No. 10-0773260 "Steam boiler with a combustion chamber of the spiral structure" is a sealed housing having a water supply pipe on one side and the steam discharge pipe on the upper side, and is installed by the side of the fixture into the inside of the housing and cylindrical The inner casing having the combustion chamber sealed by the gas chamber, the heat exchange pipes attached to the inside of the inner casing, standing vertically, maintaining spiral linearity gradually spreading outward, and a flame guide tube are installed in the center of the combustion chamber.

Referring to Figure 1, the boiler 10 using the spiral structure according to the present invention is a spiral water pipe 20 is formed by placing a plate-like plate in two rows from the center side to the outside from which the heat source is introduced into the heating source 20 By making the channel and the combustion furnace through, the water and combustion gas or the combustion gas is circulated from the center side to the outside in the form of a spiral to increase the residence time and heat exchange area can be expected higher thermal efficiency.

More specifically, in the boiler 10 using the spiral structure according to the present invention, the water pipe 20 is basically the first spiral plate 22 and the second spiral plate 24 are heated by a heat source. By forming the water pipe 20 having a spiral structure from the center side to the outside, a water channel and a combustion furnace are alternately formed between the first spiral plate 22 and the second spiral plate 24.

At this time, the water pipe 20 is composed of a start water pipe 30, the intermediate water pipe 40 and the end water pipe (60). Here, the start water pipe 30 is formed in a predetermined shape within the range that can be bent (bending) at the center side to form the beginning of the first spiral plate 22 and the beginning of the second spiral plate 24. Achieve. The intermediate water pipe 40 is formed in a predetermined shape within the range in which bending processing is possible and is continuously connected to the start water pipe 30. The end water pipe 60 is connected to the end of the middle water pipe 40 outside the middle water pipe 40 to form an end of the first spiral plate 22 and an end of the second spiral plate 24. . In addition, the start water pipe 20 and the end water pipe 60 are each end {32, 62; That is, the inner end 32 in the case of the start water pipe 20, and the outer end 62 in the case of the end water pipe 60} are the connecting portions 32 and 62, and the first spiral plate 22 and the second spiral plate. 24 is integrally connected and has a structure which is sealed. The inner and outer ends S ₁ and S ₂ of the start water pipe 30 and the inner and outer ends S ₃ and S ₄ of the intermediate water pipe 40 are positioned for a closed structure. Here, the intermediate water pipe 40 is composed of a plurality of plates according to the length of the water pipe 20, but the first intermediate plate 42 and the second intermediate plate 44 to apply the characteristic manufacturing method of the present invention. It consists of a structure that is connected to each other alternately.

As described above, since the boiler 10 using the spiral structure according to the present invention is formed by the assembly of the start water pipe 30, the intermediate water pipe, and the end water pipe 60 in which the water pipe 20 is formed separately, the high technology Since the plate bending technique and the apparatus required for the plate can be used without applying the necessary technique or bending apparatus, there is an advantage that the productivity can be sufficiently secured and practically used without the need for a high technology.

Meanwhile, in the present invention, the first spiral plate 22 and the second spiral plate 24 constituting the water pipe 20 are connected to the flat plate constituting the start water pipe 30, the intermediate water pipe, and the end water pipe 60. Element. Of course, the connection of the flat plate is required to be coupled in a sealed structure due to the nature of the water pipe 20, such a combination of the sealing structure can be made by welding typically, depending on the needs and requirements of the designer or user It can be made by applying a gasket (gasket) and packing (packing) used for watertight in the field.

In addition, the present invention has a spiral structure of the water pipe 20, which means that it is formed to have a spiral shape from the center side to the outside.

There are various forms that can be applied. That is, in the present invention, the flat plate does not refer to a plate material having a certain thickness, but refers to an unspecified element capable of forming a spiral structure, and does not limit the material, shape, dimensions, and the like.

In addition, in the present invention, the "bending processable range" refers to a range in which a flat plate may have a desired curvature to form a spiral structure using a generally known bending process technique. In other words, the range in which the bending process is possible in the present invention is shown as a circular range, but this range is substantially changed according to the range applicable in this field (the designer will set it in consideration of the bending process, convenience of work, etc.). It can be. For example, the flat state is also included in the range in which the bending process is possible.

In addition, the structure in which water flows through the water pipe 20 in the present invention can be variously set according to the needs of designers or users. For example, in the preferred embodiment of the present invention, three examples of water supply and drainage are shown. The first example, as shown in FIGS. 3A and 4A, is supplied to the outer end of the water pipe 20 to supply the water pipe 20. 2) is a structure that flows inward along the helical direction of the drain) at the inner end, the second example, as shown in Figure 3b and 4b, the water supply to the entire water pipe 20 from the lower side of the water pipe 20, as in a typical boiler {The water supply tank 14 is installed in the lower side}, and it is a structure which drains from the upper side to the outside (the drainage tank 16 is installed in the upper side). And, the third example, as shown in Figures 3c and 4c, the first and second examples of the circulation structure is configured to be applied in combination, the water pipe 20 is configured to be disconnected from each other in a predetermined section, the upper side By allowing the water pipes of each disconnected section to communicate with each other from the lower side and the lower side, the combustion gas has a structure that circulates from the center side to the outside, and the water is supplied from the outside to the center side, and the water is repeatedly circulated up and down through the communication structure of the predetermined water pipe.
