Description

Main Casing Sturcture of Oil Cornbined Gao Boiker}

The present invention relates to a main body structure including a combustion chamber of an oil combined gas boiler, and more particularly, to a main body structure of an oil combined gas boiler which increases the contact area of a heat exchanger to improve hot water supply and heating efficiency.

As is well known, a boiler that combines oil and gas is composed of a combustion chamber with a burner, a golden pipe surrounding the combustion chamber, a heat exchanger with a heating tube, and an induction pipe for guiding the combustion gas. In the conventional structure of the injection-type gas boiler, as shown in FIG. 9, a heating water pipe 103 is installed in a concentric circle in which a spiral hot water supply pipe 104 is built around the combustion chamber 102 of the burner 101. Combustion gas pipe 105 is installed between the pipe 104 and the heating water pipe 104, the combustion gas is injected in the direction of the arrow from the top-down burner 101 is downward along the inner surface of the heating water pipe 103. After being moved, it is discharged to outside air via the combustion gas pipe 105 provided between the hot water supply pipe 104 and the heating water pipe 103.

However, since the combustion gas is discharged by the combustion gas pipe 105 in the conventional boiler of the downward injection combustion gas, the heat exchange efficiency naturally decreases as the thermal contact with the heating water pipe 103 contacts only the inner surface of the fuselage. The disadvantages of reducing the efficiency of the boiler and the problem of setting the boiler body large to increase the flow structure of the combustion gas.

Accordingly, the present invention has been invented to solve the conventional problems as described above, the combustion gas of the boiler by maximizing the heat transfer area by forming a flow path so that the combustion gas of the combustion chamber is transmitted through the inner and outer surfaces of the front and rear of the heating tube. It is an object of the present invention to provide a main body structure of an oil combined gas boiler capable of increasing efficiency and making the body of a boiler more compact.

The present invention for achieving the above object comprises a burner, a combustion chamber in which the burner is installed, a water supply pipe built in a heating water pipe around the combustion chamber, and a combustion gas passage communicating with the combustion chamber. The inner and outer combustion gas passages are formed on the inner and outer surfaces of the heating water pipe in which the spiral water supply pipe is built, and the outer cylinder of the insulation is installed at the outermost portion to concentrically arrange the outer combustion gas passage. It is.

Another embodiment of the present invention connects the lower bottom of the heating water pipe to each other by a connection water pipe or to embed a separate heating water pipe.

In still another embodiment of the present invention, the lower portion of the heating water pipe is integrally formed, but combustion gas guide tubes of equal intervals are formed and connected to each other.

In another embodiment of the present invention, the outer combustion gas passage formed on the outer surface of the insulating material outer cylinder and the heating means is equipped with a partition plate for increasing the heat exchange area having a zigzag cross section.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of a first embodiment showing a main body structure of an oil combined gas boiler according to the present invention.

As shown in the drawing, the burner 1, the combustion chamber 2 in which the burner 1 is installed, the water supply pipe 4 embedded in the heating water pipe 3 around the combustion chamber 2, and the Combustion gas passage (5) communicating with the combustion chamber (2), the combustion gas passage (5) is the inner and outer combustion on the inner and outer surfaces of the heating water pipe (3) in which the spiral feed pipe (4) is embedded The gas passages 5a and 5b are formed and connected to each other, and the heat insulating material outer cylinder 6 is provided in the outermost part in order to arrange this outer combustion gas passage 5b concentrically.

Therefore, the combustion gas combusted by the burner 1 is injected downward from the combustion chamber 2 along the direction of the arrow, through the inner combustion gas passage 5a of the heating water pipe 3, and the outer cylinder 6 and the heating water pipe 3 Since the combustion gas is moved upward through the outer combustion gas passage (5b) formed between the and exits to the outside air, the combustion gas is to transfer heat directly to the inner and outer surfaces of the heating water pipe (3).

On the other hand, Figure 2 is a second embodiment of the present invention, the difference from the previous embodiment is a structure in which a separate auxiliary heating water pipe 7 is provided to be spaced apart from the bottom bottom of the heating water pipe 3, in this case the combustion gas Is heated to heat the auxiliary heating water pipe. The rest of the structure is the same as in the first embodiment.
