Description

High Performance High Efficiency Boiler {High Performance High Efficiency Boiler}

The present invention relates to a high-performance, high-efficiency boiler, and more specifically, to a high-performance, high-efficiency boiler that can maximize thermal efficiency.

Generally, in a cast iron boiler with an existing section connection structure, a combustion gas chamber is formed within the section, and combustion gas burned by a burner enters this combustion gas chamber and heats the section heating plate, generating high heat on one side of the section. By heating the water in the already formed water channel to generate and supply hot water or steam heat source, it is possible to use hot water as well as indoor heating.

Figure 1 shows the main configuration of an existing cast iron boiler, in which a plurality of section heating plates made of cast iron are combined and a first combustion chamber, which is a burner combustion furnace, is formed at the center of the lower end of the section heating plates. In addition, a second combustion chamber and a third combustion chamber are formed on the upper part of the first combustion chamber, and a water inlet passage through a water intake pipe is formed at the lower part of the heating plate of each section and a blowing water passage is formed at the upper part.

In a conventional cast iron boiler of this configuration, the combustion gas burned by the burner heats the section heating plate in the first combustion chamber with high heat, and some of it is moved to the second combustion chamber in the inversion ramp to heat the section heating plate again, and then this combustion gas is 3 It is moved to the combustion chamber and the section heating plate is heated again to generate hot water or steam heat source.

In this way, the heating plate is heated as the combustion gas passes through the first combustion chamber, the second combustion chamber, and the third combustion chamber. As the number of combustion chambers through which the combustion gas passes increases, the heat absorption rate improves, and the volume of the boiler increases accordingly. The disadvantage is that the manufacturing cost is high and constructability is poor due to limitations in installation space.

In addition, cast iron boilers with combustion gas passages of the existing semi-inverted combustion method do not distribute combustion flames uniformly due to the instantaneous scattering of flames when burning gaseous fuel, resulting in incomplete combustion such as lift-off phenomenon. There are disadvantages such as an increase in the amount of carbon monoxide and nitrogen oxides generated, lowering combustion efficiency, and increased generation of soot and NOx (nitrogen oxides).

Therefore, the purpose of the present invention is to provide a high-performance, high-efficiency boiler that can increase combustion efficiency by uniformly distributing combustion chamber flames.

According to the present invention, the combustion chamber flame is distributed evenly due to the static pressure penetration hole to improve the existing low thermal efficiency, thereby enabling complete combustion. This increases the heat transfer rate for heating water, which can improve energy efficiency. It works.

Hereinafter, a high-performance, high-efficiency boiler (1) according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

Prior to explanation, the present invention is a high-performance, high-efficiency cast iron boiler composed of one or more section parts 10 that function as heat transfer plates combined in a row, and the shape of the path through which combustion gas and hot water moves through the internal structure of the section part 10 and the Please note that the explanation focuses on placement.

The high-performance, high-efficiency boiler 1 includes a section section 10, and as shown in FIG. 6, a plurality of section sections 11, 12, 13, and 14 can be overlapped and combined to form a high-performance, high-efficiency boiler. .

The section portion 10 is composed of a plurality of plates arranged overlapping each other. The section portion 10 includes a first section portion 11, a second section portion 12, a third section portion 13, and a fourth section portion 14. If necessary, the number of section parts 10 may be 8 to 16. The number of section portions 10 is not limited.

As shown in Figure 2 or 3, the plurality of section parts 11, 12, 13, and 14 include a section main body 111, a combustion chamber forming part 112, a gas flow path forming part 113, and a through hole forming part ( 114), section lower water inflow passage part 115, hot water main forming part 116, flow guide forming part 117, combustion discharge forming part 118, combustion gas guide forming part 119, heat transfer fin forming part (120), it includes a section upper hot water connection passage 121 and a fluid discharge outlet 122.

The section body 111 has a plate shape that is overlapped to form a combustion gas space 111a and a water heating space 111b.

The combustion chamber forming portion 112 forms a combustion chamber by penetrating the section main body 111 in the overlapping direction in a plate-shaped overlapping arrangement.

Meanwhile, the combustion chamber forming portion 112 is a space in which combustion gases combusted by the burner 200 connected to the foremost section 11 are introduced and combustion occurs most frequently.

The gas flow path forming portion 113 forms a gas flow path through which combustion gas generated in the combustion chamber moves while adjacent section bodies 111 are arranged overlapping in a plate shape.

The through-hole forming portion 114 is disposed in an area where combustion gas moves at the rear end of the gas flow path and forms a static pressure through-hole that penetrates the section body 111 in the overlapping direction in a plate-shaped overlapping state. The static pressure penetration hole can prevent incomplete combustion, such as lift-off, from occurring due to uneven distribution of combustion flames due to the instantaneous scattering of flames when burning gaseous fuel. Since the combustion chamber flame is distributed evenly, complete combustion can be achieved. This increases the heat transfer rate for heating water, thereby improving energy efficiency.

The section lower water inflow passage 115 may form an inflow pipe through which water (high temperature water, saturated water) flows into the lower end of the water heating space 111b.

The hot water main forming part 116 can form a hot water main pipe in which water (high temperature water, saturated water) flowing into the inlet pipe moves along the outside of the combustion chamber in a state where adjacent section bodies 111 are arranged overlapping in a plate shape. .

The flow guide forming portion 117 may be formed at the rear end of the hot water main forming portion 116 through which water moves to form a flow guide that guides the movement of water (hot water, saturated water).

Meanwhile, as shown in FIG. 5, the flow guide forming portion 117 is located on the upper side of the hot water main pipe and is formed in a vertical direction from a straight guide section 117a and an end of the straight guide section 117b. It consists of an inclined guide section 117 that is inclined in the outward direction to facilitate the upward and downward movement of water (hot water, saturated water) moving inside the section portion 10.

The combustion exhaust forming portion 118 may form a combustion exhaust port through which combustion gas is discharged by passing through the plurality of section bodies 111 in the overlapping direction in a plate-shaped overlapping arrangement.

Here, the combustion discharge part can be formed below the water level of the water (high temperature water, saturated water) in the water heating space to prevent wasted heat, thereby improving energy efficiency.

The combustion gas guide forming portion 119 may form a combustion gas guide that guides combustion gas discharged from the combustion outlet to flow downward into the combustion outlet.

The heat conduction fin forming portion 120 may be formed to protrude from a plurality of regions of the section body 111 in a combustion gas space formed by overlapping the adjacent section bodies 111 in a plate shape.

The heat conduction fins are used to turbulent the flow of the moving combustion gas and at the same time extend its residence time. As the combustion gas passes between the plurality of heat conduction fins, the movement path of the combustion gas is extended, and the combustion gas flows into the gas flow path of the section. By allowing it to stay for as long as possible, the heat transfer effect can be improved as a result.

The section upper hot water connection passage 121 is formed with a hot water connection passage in an overlapping direction, allowing water (hot water, saturated water) to flow while the plurality of section bodies 111 are arranged in an overlapping plate shape. do.

The fluid discharge discharge unit 122 is a device in which heated high temperature water and saturated water vapor flowing through the section upper hot water connection passage 121 are discharged to the outside in a state in which a plurality of section bodies 111 are arranged overlapping in a plate shape. makes it possible.

Figures 3 and 4 are exemplary diagrams showing the flow of combustion gas.

Referring to FIGS. 3 and 4, combustion gas flows into the combustion chamber and combustion begins, and the combustion gas moves to a plurality of gas passages between the plurality of section portions 111 formed by the gas passage forming portion 113 to cause combustion. It moves into the gas space (111a) and allows the combustion gas to instantly move horizontally through the static pressure through-hole formed by the through-hole forming portion (114) and at the same time ensures uniform distribution of the combustion chamber flame, thereby ensuring complete combustion. . Afterwards, the combustion gas moves upward and is bypassed by the combustion gas guide, moving to the combustion outlet at the bottom and being discharged to the outside.

Figure 5 is an exemplary diagram showing the flow of water (high temperature water, saturated water) in the water heating space.

Water flows into the inflow pipe formed by the section lower water inflow passage 115, moves the hot water main pipe formed by the hot water main forming part 116, and moves to the upper water heating space 111b. There is a slit between the hot water main pipes. It is formed and divided into the inner and outer parts, and the water (high temperature water, saturated water) moves. The overall circulation is achieved by the flow guide formed by the flow guide forming part 117, and the heated water exchanges heat with each other to ensure uniform circulation. As the temperature is distributed, the hot water is discharged through the outlet.

Here, the uppermost water level surface of the hot water in the water heating space (111b) is located at least above the uppermost side of the combustion outlet through which the combustion gas is discharged, so that the heat of the combustion gas is efficiently transferred to water (high temperature water, saturated water). This allows heat transfer efficiency to be improved.

Meanwhile, as shown in FIG. 7, it is preferable to operate the water level gauge 130 so that the uppermost side of the combustion outlet is located below the lowest water level of hot water.

Due to the above-mentioned high-performance and high-efficiency boiler, the combustion chamber flame is distributed evenly due to the constant pressure penetration hole to improve the existing low thermal efficiency, thereby enabling complete combustion. This increases the heat transfer rate for heating water, thereby improving energy efficiency. It can be improved.

In addition, since the circulation of water (high temperature water, saturated water) within the water heating space 111b can occur naturally, the heat transfer rate through which heat from the combustion gas space 111a is transferred to the water heating space can be improved, and the water heating space can be improved. Since the thermal contact area between the space 111b and the combustion gas space 111a increases, heat transfer efficiency can be increased.

In addition, since the combustion gas can move from the combustion gas space (111a) to the upper space and bypass the combustion outlet, the combustion gas can stay in the combustion gas space (111a) for a long time, so heat transfer efficiency can be improved, and the flow of combustion gas can be improved. By making it turbulent and at the same time extending the residence time of the combustion gas, the heat transfer effect to the water heating space (111b) can be improved.
