It's about one wood boiler.

Wood boilers, which are generally used as a main fuel among wood boilers, are used to heat water by simply igniting wood from the inside of a furnace to heat water, and to circulate the heated water to the room to provide room heating. In some cases, heated water can be used directly as hot water.

Thus, the water heated by wood is required to maintain the proper temperature because it is directly used as hot water or circulated for heating, but when hot water is used, a large amount of wood fuel is used because it needs to be reheated by replenishing the amount of water. There was a problem.

In order to solve this problem, wood boilers have been improved to include liquid fuel as well as wood fuel, so that fuel can be replaced with liquid fuel to maintain the use of heating and hot water.

As another embodiment of the present invention, including all of the configuration of the embodiment, as shown in Figure 2, the plurality of pipes 81 and parallel to the hot water pipe 60 located on the upper side, and the pipe 81 It may be carried out further comprising a heat exchanger (80) consisting of a blower (82) for sucking and blowing outside air.

The present invention constituted as described above is a technology that significantly improves the thermal power of the furnace by boiling water to generate high temperature steam and heating water using the same, as well as supplying steam to the furnace.

When the coke heated to a high temperature is brought into contact with water vapor, heat is absorbed and a mixture gas of carbon monoxide and hydrogen is generated. At this time, a mixed gas of carbon monoxide and hydrogen, that is, water gas, is very high during combustion. The idea is to generate high heat.

On the other hand, while water in the liquid state has a maximum temperature of 100 ° C., water vapor is a colorless, odorless transparent gas generated by a change in the state of water due to temperature or pressure, and may exist only at a critical temperature of 374 ° C. or higher.

Therefore, it is more efficient to heat the water by allowing the hot steam to exchange heat with the stored water than to cut off a certain amount of water directly through the furnace to heat the water.

That is, the present invention generates a high-temperature steam by directly heating a predetermined amount of water stored in the steam generating tank 30 using the furnace 20, the generated steam to the furnace 20 and the water supply tank 10 By supplying each of them, the same amount of fuel can be used to generate a higher calorific value.

Hereinafter, the use of the present invention will be described in more detail.

<Use example>

As an example of use of the present invention, as shown in FIG. 2, first, a suitable amount of water is stored in the water supply tank 10 by using the water supplement pipe 12 on one side of the water supply tank 10, and at the same time, the steam generation tank 30. Supply water to the steam generating tank 30 through the water supply pipe 31 of to maintain the proper water level. Here, the proper water level of the water stored in the water supply tank 10 and the steam generating tank 30 is different depending on the storage capacity of the water supply tank 10 and the size of the brazier 20. Deformation is carried out.

When water of the appropriate level is supplied to the water supply tank 10 and the steam generating tank 30 through the above process, as shown in FIG. 30) The water stored inside is heated, thereby producing hot steam.

The high temperature steam generated by the combustion of the furnace 20 is directed to the pressure nozzle 40 along the induction pipe 41 by its own pressure, and high pressure is generated in the high temperature steam to the bottom surface inside the furnace 20. Water vapor is discharged.

Through this, the water vapor supplied inside the furnace 20 reacts with wood as a fuel to generate water gas, and since the water gas is combusted to obtain a higher thermal power, high thermal efficiency is obtained when using the same amount of wood fuel. .

Here, if the amount of water vapor that is greater than the amount of water vapor supplied into the furnace 20 is generated, the excess water vapor is supplied to the water supply tank 10 through the water vapor supply pipe 50, so that the water stored in the water supply tank 10 This water vapor keeps it warmed up.

The water in the preheated water supply tank 10 is sucked through the water supply pump 70 and flows along the hot water pipe 60 as shown in FIG. 5, and the hot water pipe 60 is in the furnace 20. Due to the hot heat generated, the water is heated, and the water flowing through the hot water pipe 60 is heat-exchanged with the hot water pipe 60, and the water is heated and discharged. At this time, since the water in the water supply tank 10 is preheated, during the heat exchange, the hot water pipe 60 is not cooled to a low temperature and maintains a proper high temperature, thereby rapidly heating the water flowing in the hot water pipe 60. It becomes possible.

On the other hand, the waste heat passing through the hot water pipe 60 is discharged to the outside through the communication 21 on the upper side of the furnace 20, in this case a plurality of pipes 81 and the communication between the hot water pipe 60 and the communication (21) It is further provided with a heat exchanger (80) made of a blower 82 may be carried out so that the hot air can be supplied to the room by sucking the outdoor air.

This is, before the waste heat rises and is discharged into the communication 21, the heat exchanges with the plurality of pipes 81, and then is discharged to the outside, and the blower 82 on one side sucks outside air and heats the inside of the pipe 81 heated. By passing through the outside air is heat-exchanged with the pipe 81 generates hot air, and by supplying the generated hot air to the room, it is possible to realize the floor heating using hot water and space heating using hot air at the same time.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is obvious that all modifications belong to the appended claims.
