Description

Total heat exchanger for a boiler having a fixed insulation frame {Boiler heat exchanger with fixed insulation frame}

The present invention relates to a total heat exchanger for a boiler, and more particularly, by fixing an insulating material formed higher than the height of the metal fiber burner to a fixed frame formed higher than the height of the metal fiber burner to block the flame ejected from the metal fiber burner, It relates to a total heat exchanger for a boiler having an insulating material fixing frame that allows the insulating material to be firmly fixed in the vertical direction on both sides of the bottom surface of the fiber burner.

In general, boilers are installed in various buildings such as homes, offices, or other factories to supply hot water and heating water through heat exchange with a heat source generated by burning a mixed fuel of air and gas.

To this end, the boiler includes a fuel supply that receives and mixes air and gas from the outside, and then supplies the mixed fuel to the burner, and a fuel supply that receives the mixed fuel from the fuel supply and burns it by an ignition device to generate a flame. It includes a heat exchanger that heats the heating return to the heating water by allowing the burner and the heating return water to exchange heat with the heat source supplied from the burner.

In particular, in recent years, there are many condensing heat exchangers equipped with a sensible heat exchanger in which heating return exchanges primary heat with sensible heat generated by a burner and a latent heat exchanger in which heating return exchanges secondary heat with combustion gas that has undergone heat exchange in the sensible heat exchanger. A boiler having such a condensing heat exchanger is called a condensing boiler.

In addition, heating and hot water boilers used at home can be divided into oil boilers and gas boilers according to the fuel used.

Patent Document 1 shows a conventional heat exchanger. Referring to this, a burner assembly that causes a combustion reaction and a flame due to the combustion reaction are located downstream from the burner assembly based on the flow direction of the combustion gas. a combustion chamber that receives the sensible heat generated by the combustion reaction, and a sensible heat heat exchanger that heats the heating water. A latent heat heat exchanger that receives latent heat and heats the heating water, and a sensible heat insulating pipe arranged adjacent to the sensible heat heat exchanger to receive the heating water and flow it through the inside in order to insulate the sensible heat heat exchanger.

Here, the combustion chamber forms a burner on its inner upper surface, and forms a combustion chamber insulation part attached to the side wall of the combustion chamber, thereby blocking the flame ejected from the burner from being transmitted to the side wall of the combustion chamber.

Then, the flame ejected from the burner is blocked from the combustion chamber insulation to prevent direct contact with the side wall of the combustion chamber, and accordingly, the combustion chamber insulation portion is prevented from being heated by the flame.

At this time, the combustion chamber heat insulating part is formed to protrude in the vertical direction so as to extend from the upper end to the lower end inside the combustion chamber, and surround and cover the side wall of the combustion chamber.

And, the flame ejected from the burner is directly sprayed downward to heat the sensible heat exchanger, and by allowing the heating water passing through the sensible heat exchanger to exchange heat with the sensible heat exchanger, the heating water passing through the sensible heat exchanger is heated.

In addition, the hot air moving downward through the sensible heat exchanger heats the latent heat exchanger, and the heating water passing through the latent heat exchanger is heated.

However, in Patent Document 1 as described above, the combustion chamber insulation portion extends from the upper end to the lower end along the side wall of the combustion chamber, so that the ejection angle of the flame ejected from the burner is sharply limited. Compared to the insulated pipe, the heat is concentrated in the centrally located sensible heat insulating pipe, so the heat cannot be transmitted evenly to the sensible heat insulating pipe. By simply attaching or closely attaching the combustion chamber insulation to the side wall of Due to this, there is a risk that the combustion chamber insulation part is inclined or separated from the sidewall of the combustion chamber in the direction of the burner, and the sidewall of the combustion chamber is directly exposed to the flame ejected from the burner due to the separation of the combustion chamber insulation portion, so that the heat of the flame is transferred to the sidewall of the combustion chamber In particular, thermal deformation occurs when the side wall of the combustion chamber comes into contact with the flame, thereby causing damage to the side wall of the combustion chamber, thereby reducing the reliability of the product.

In this case, the height of the insulating material fixing frame 300 and the insulating material 400 is relatively higher than that of the metal fiber burner 200 .

Here, the fixing plate 301 of the insulating material fixing frame 300 is fixed to the bottom surface of the metal fiber burner 200 by a welding method (eg, spot welding), and the fixing plate 301 and the supporting wall 302 are attached to the fixing plate 301 and the supporting wall 302. In a state in which the upper surface and the side surface of the insulator 400 are in close contact, the bottom surface of the insulator 400 is pressed upwardly with the compression plate 303 bent at the lower end of the support wall 302 by pressing the lower surface of the heat insulator 400 upward, so that the insulation fixing frame 300 ) in the heat insulating material 400 is fixed.

In particular, the insulating material 400 fixed in the insulating material fixing frame 300 is in close contact with the blocking guide 304, the upper end of which is bent in the direction of the compression plate 303 from one end of the fixing plate 301 . It is supported so that it is prevented from being tilted in the direction of the metal fiber burner 200 within the insulating material fixing frame 300 or from being separated from the insulating material fixing frame 300 .

Both ends are caught by the side guides 302a, and the compression plate 303 is blocked from being bent upward by a predetermined angle or more.

Next, the auxiliary heat insulating material 400a formed to have a relatively lower height than the heat insulating material 400 is fixed to the extended frame 301a extending from both sides of the fixing plate 301, and in a direction perpendicular to the heat insulating material 400 Install the auxiliary insulating material (400a).

In particular, the blocking guide 304 supporting the upper side of the insulating material 400 has a height relatively higher than the height of the flame sprayed to the side of the metal fiber burner 200, so that it directly hits the flame. By preventing contact, thermal deformation due to contact with the flame is prevented.

On the other hand, the auxiliary heat insulating material 400a installed on the extension frame 301a extending from the fixing plate 301 causes the flame ejected to the side of the metal fiber burner 200 to be emitted from the peripheral edge of the metal fiber burner 200 and the housing.
