TECHNICAL FIELD The present invention relates to the field, and more specifically, by using an intermediate relaxation spiral core, the combustion flame can be spread through the middle portion of the core so that the combustion flame can be evenly transmitted to the core. The present invention relates to a waste heat-free boiler having an intermediate-relaxing spiral core, which can reduce manufacturing costs by preventing waste heat from being generated and at the same time using a low-cost spiral core.

In general, boilers are classified into firewood boilers, coal boilers, briquette boilers, oil boilers, gas boilers, etc., depending on the type of fuel burned, and steam boilers and special oil heat medium boilers, depending on the type of medium for transferring heat. Wow, it is also divided into hot water boiler.

Conventional boilers are composed of a burner for igniting fuel to provide a flame, a heat exchanger for transferring heat generated from the burner to water, and a body in which the burner and the heat exchanger are installed. Developing a structure to improve heat transfer efficiency is key to boiler research.

The technology related to a boiler with relatively high heat transfer efficiency is described in the "Assembly Hot Water Boiler" of Korean Utility Model Registration Publication No. 2000-184241 (Announcement date: June 1, 2000), and Registration Registration No. 2001-258015. "Stairless, Heat-free Hot Water Boiler" of the issue (Announcement: December 31, 2001), and "Doorless, Heat-Free Hot Water Boiler" of Publication No. 2002-265339 (Announcement: February 25, 2002); No. 2003-333998 (published date: November 19, 2003) has been disclosed by the applicant in the "Capacity Variable Heat-Free Heat Boiler".

However, the conventional boiler as described above does not use a relatively inexpensive spiral core or has a problem in that thermal efficiency is lowered even when the spiral core is used.

An object of the present invention is to solve the conventional problems as described above, by using the intermediate relaxation spiral core to allow the combustion flame to be diffused through the middle portion of the core so that the combustion flame can be evenly transferred to the core. The present invention provides a waste heat-free boiler having an intermediate-relaxing spiral core, which can efficiently reduce combustion costs by using combustion heat efficiently and reduce manufacturing costs by using a low cost spiral core.

As a means for achieving the above object, the configuration of the present invention, the flame tube is formed in the inner center and the fire wall is installed in the periphery of the flame tube and the inner side is formed with a locking jaw, and A burner installed in one flame tube to provide thermal power, a pedestal placed on the locking jaw, a preheating tube supported by the pedestal and preheating external air required for combustion of the burner; A plurality of cores placed on top of the pedestal, each having an inlet for connection to the inlet storage unit and a outlet for connecting to the hot water storage unit respectively formed at the upper end, and forming a spiral in which the middle part is relaxed; It is formed on the edge and the upper part of the body and is for discharging the combustion gas generated from the inside of the body to the outside. It comprises a barrel.

Is a perspective configuration diagram of a middle part relaxed helical core of Fig. 3 is a plan configuration diagram of a pedestal of a heat-free boiler having an intermediate part loosening spiral core according to an embodiment of the present invention, Figure 4 is an embodiment of the present invention Fig. Is a plan view of the hot water storage unit of the heat-free boiler having the middle part relaxed spiral core according to the example.

As shown in Figures 1 to 4, in the configuration of a heat-free boiler having an intermediate-relaxing spiral core according to an embodiment of the present invention, the flame tube 71 is formed in the inner center and the flame A fireproof wall 74 is installed at the periphery of the tube 71, and a body 7 having locking jaws 72 and 73 is formed at one side thereof, and the flame tube 71 is installed to provide thermal power. The burner 1, the pedestals 81 and 82 placed on the locking jaws 72 and 73, and the external air supported by the pedestal 81 and required for combustion of the burner 1 are preheated. The preheating pipe 5 and the inlet port 21 to 29 are placed on the pedestal 82 to be connected to the inlet and storage unit 2, respectively, and are provided at the lower end of the hot water storage unit 4. Water outlets 41 to 49 to be connected are formed at the upper end, and a plurality of the intermediate parts form a relaxed spiral. Control (31-39)) and is formed on the edges and top portion of the one body (7) and comprise a communication passage (6) for allowing the combustion gas generated from the interior of the body 7 is discharged to the outside.

With the above configuration, the action of the heat-free boiler having the middle part relaxed spiral core according to an embodiment of the present invention is as follows.

When the burner 1 is ignited, the flame continuously generated from the burner 1 heats the plurality of cores 31 to 39 placed on the pedestal 82 through the flame tube 11.

At this time, the preheating tube 5 placed on the pedestal 81 utilizes heat efficiently by preheating and providing external air necessary for combustion of the burner 1 using the combustion heat.

In general, when a plurality of spiral cores are installed, combustion flames are blocked by the cores so that they do not propagate sideways. Each of the plurality of cores 31 to 39 has one example shown in FIG. As described above, since the upper and middle portions and the lower portion are bent to form a structure in which the density of the middle portion is relaxed than the density of the upper and lower portions, the combustion flame is opened in the middle portion of the plurality of cores 31 to 39. Propagation to the side through) can increase the thermal efficiency.

The plurality of cores 31 to 39 are heated by the flame discharged from the burner 1 through the flame tube 71. The hot water is blown out of the burner 1 to primarily heat the plurality of cores 31 to 39. The flame reaching the storage unit 4 is reflected by the hot water storage unit 4 and descends again to form a structure in which waste heat is hardly generated by secondary heating of the plurality of cores 31 to 39.

When the plurality of cores 31 to 39 are heated in this way, and the water inside each core is heated hot, the hot heated water is stored in the hot water storage unit 4 and then connected to the hot water storage unit 4. It functions as a boiler by being able to draw outside and use for heating through a hose.

As shown in FIG. 4, the hot water storage unit 4 may prevent the upper and lower surfaces from being excessively expanded and burst by hot temperature by bridging each other through spot welding at various points.

On the other hand, the gas that is filled in the interior of the body 7 by the combustion of the burner 1 is discharged to the outside in the direction of the arrow through the communication 6 formed on the edge and the upper portion of the body 7 burner 1 ) So that combustion can be performed smoothly.

As described in the above embodiment, the present invention uses the middle spiral helical core to allow the combustion flame to be diffused through the middle portion of the core so that the combustion flame can be evenly transferred to the core. It is possible to reduce the manufacturing cost by using a low-cost spiral core while preventing waste heat from being generated.
