Description

Firewood Boiler {BILIER USING A FIREWOOD AS A FUEL}

The present invention relates to a firewood boiler that can use waste wood or waste wood as fuel, and in particular, when the fuel is being burned, heat generated from the fuel can be circulated in the boiler to increase thermal efficiency, as well as It relates to a firewood boiler that can use hot water quickly by forming the cold and hot water pipes surrounding the boiler water pipe.

In general, the main fuels of boilers that have been used for heating in homes include briquette boilers mainly using coal or briquettes, oil boilers using kerosene and diesel oil, and gas boilers using LPG and natural gas. . While briquette boilers are cheap, their use is gradually being reduced due to the treatment of natural ashes and toxic gas generation.Boilers using oil or gas do not generate ash and toxic gas, which are disadvantages of briquette boilers, but purchase oil or gas. There is a problem that the cost is high and the cost of the boiler itself is high.

Moreover, the oil boiler or gas boiler is a core component of the burner operated by the temperature sensor which senses the temperature of the room heating. When the burner is stopped, the heat source in the boiler is completely extinguished and the burner is operated during the burner operation. Since only the remaining heat remains, the circulating water in the water tank heating the room or supplying the hot water is rapidly cooled, so a large amount of heat is required when the burner is restarted to reheat the circulating water, and thus a large amount of energy is lost. There was a problem.

In addition, since the hot water is supplied only when the water in the entire tank is heated, the conventional boiler is not only able to receive hot water quickly, but also cannot use hot water continuously.

The present invention is designed to solve the above problems, and when using firewood such as waste wood or waste wood as fuel, the heat generated by staying in the boiler for a longer time to make more heat exchange with the heating bath. There is this.

Another object of the present invention is to provide a firewood boiler that can use hot water quickly and continuously by the cold and hot water pipe that wraps the pipe of the heating water tank heat exchanged with the heat source in the form of a coil.

7: hot air guide passage 8: cleaning hole

9: separator 10: input door

11: cold water supply pipe 12: hot water supply pipe

In order to achieve the above object of the present invention, the separator is formed in the upper part of the incineration chamber consisting of a rectangular cylinder and installed through the outside so that the firewood can be put on one side, the heat between the separation tank heating tank This is accomplished by forming an air guide passage.

Figure 1 is a perspective view of the present invention, Figure 2 is a cross-sectional view of Figure 1, the firewood boiler of the present invention incineration is fired after the firewood (2) such as waste wood or waste wood is received in the boiler through the input door (10) Including the chamber (1), the upper part of the incineration chamber (1) is heat-exchanged with the heating water pipe (3) in the boiler and the air discharged to the flue (13) so that the heat exchange with the heating water tank (4) A hot air guide passage 7 towards the flue 13 is formed. That is, the heating water tank 4 is located in the upper portion of the guide passage (7). The heating water tank 4 in the upper part of the incineration chamber 1 is connected to the heating water tank 4 arranged to surround the incineration chamber 1, and the water whose temperature is increased by heat exchange during the passage of the heating water tank 4 is temporarily It is a water tank collected by the water, and the temperature of the water collected in the heating water tank 4 is supplied to the place to be heated through the heating water supply outlet pipe (6). Reference numeral 5 is a cold water supply pipe for heating connected to the heating water pipe (3) to supply the heating water to the boiler.

Furthermore, a separate separator 9 for separating the guide passage 7 and the incineration chamber 1 is formed in the lower portion of the guide passage, and the material contained in the discharge air is provided at the end of the separator 9 through which air is discharged. Falling pairs of cleaning holes 8 are installed, and the flue 13 through which combustion air is discharged is installed vertically above the cleaning holes 8.

A separate hot water pipe 14 is installed in the heating water pipe 3, and the water of the hot water pipe is connected to a cold water supply pipe 11 through which cold water is supplied and a hot water supply pipe 12 through which hot water is discharged.

The input door 10 is preferably provided with an automatic air supply 10a and a manual air supply 10b so that smooth air can be supplied during combustion of firewood. In addition, the input door 10 is provided with a locking device 15 for locking the input door to the boiler so as to seal the incineration chamber 1 into which the firewood 2 is injected and combusted.

When the firewood boiler of the present invention configured as described above is put into the firewood (2) through the input door (10) and burned, heat exchange with the heating water pipe (3) supplied with water through the heating cold water supply pipe (5) The elevated temperature water is collected in the heating bath 4 above the incinerator 1, and cold cold water is circulated continuously through the heating water pipe 3.

On the other hand, the air heated in the incinerator (1) is heat exchanged with the heating water pipe (3) and then hit the separator (9) of the upper and guided to the rear of the incineration chamber (1), and then again the hot air guide passage (7) The heat exchange is made to the upper heating water tank 4 and then discharged into the flue 13 through the cleaning port 8.

When the heat-exchanged air is guided to the hot air guide passage 7 as described above, the heat contained in the air is not only the heating water tank 4 in the upper portion but also the hot water pipe 14 in the lower separator 9. Transient heat exchange is further achieved.

Then, the ash contained in the air discharged through the cleaning device (8) to the upper flue 13 is dropped to the cleaning device (8) and then removed.

The firewood boiler of the present invention, which is constructed and used as described above, is primarily heat exchanged with a water pipe for heating using a heat source generated in the incineration chamber 1, and then, the discharged air is redirected backward by a separator to heat air. By discharging to the outside through the guide passage (7) to naturally delay the discharge time of the hot air to increase the heat exchange time of the boiler increases the heat exchange rate of the boiler, as well as separate hot water for the separator (9) By installing the water pipe 14, not only heating but also hot water can be used effectively.

In addition, the firewood boiler of the present invention can be used in connection with the existing oil boiler, when the heat quantity of the firewood boiler is lowered by being detected below a certain temperature by the temperature sensor (T) mounted on the water supply outlet pipe (6) for heating. The oil boiler is activated and continuous heating takes place.

The firewood boiler of the present invention is configured to work as described above, the heat exchange efficiency is increased as well as a very useful design that can use hot water quickly.
