The present invention relates to an oil boiler that is used a lot in the home, and in more detail, the oil boiler is provided with a reburn means and a noise prevention function generated during combustion, and thus the combustion efficiency and thermal efficiency can be further improved. The present invention relates to a boiler and its fuel combustion and noise prevention method.

In the conventional oil boiler, as shown in FIG. 1, the burner unit 20 which burns the supplied fuel and the combustion unit 10 which reheats the incompletely burned fuel and heats the heating water by the heat of combustion generated during combustion. And a gas discharge pipe 30 through which waste gas is discharged from the combustion unit 10.

The combustion unit 10 is composed of a baffle and a noise preventing means for forming a combustion chamber, the fuel is supplied into the combustion unit 10 through the burner unit 20 mounted outside the combustion unit 10 and burned, It consists of multiple plates for the reburn of incompletely burned fuel.

The noise preventing means is provided with a normal sound absorbing hole for absorbing the combustion sound to prevent the generation of noise.

In the conventional oil boiler having the above configuration, the combustion efficiency depends on the efficient use of the heat of combustion and the buff and noise preventing means of the combustion unit 10.

If excessive heat release prevention measures are taken to keep the heat in the combustion chamber for a long time, the combustion load is excessively increased, and the heat loss prevention means is largely neglected to improve the combustion capacity.

Therefore, an appropriate number of baffles were required by the appropriate heat dissipation preventing means in the combustion section 10.

In addition, since the combustion sound generated in the combustion section 10 is very loud, noise suppression means for attenuating the combustion sound in stages is required because it is difficult to prevent noise with one silencer.

A conventional oil boiler and its fuel combustion method associated with this technique are shown in FIG. For example, as illustrated in FIG. 2A, the combustion unit 1A includes a main body 10a formed of a water tank 11a and a combustion chamber 12a, and an upper cover 20a in which a heat insulator 21a is embedded and a gas outlet 22a is formed. ), A baffle 30a in which the plate 31a is mounted so that the combustion chamber 12a is zigzag-formed in the lower end of the main body 10a, and a plurality of sound absorbing holes 41a are placed on the upper end of the baffle 30a. It is composed of a snow silencer 40a.

The combustion section 1A of the oil boiler having the above-described configuration, the fuel is combusted in a zigzag direction from the burner section along the plate 31a of the baffle 30a, the strong combustion sound generated at this time is buffle ( Reflected by the plate 31a of 30a, it is absorbed by the sound absorbing hole 41a of the silencer 40a placed on the top of the baffle 31a.

However, the combustion part 1a does not reburn much soot generated during initial ignition or extinguishing, and the soot accumulates easily in the combustion chamber 12a and the plate 30a of the baffle 30a, causing incomplete combustion. It was to be.

In addition, the soot heat efficiency of the fuel is lowered by the soot, the heating capacity of the heating water is lowered, in particular, if the sound-absorbing olol 41a of the muffler (40a) is blocked, the noise protection effect is also significantly reduced. And removing the soot of the silencer 40a was required.

Therefore, the oil boiler having the combustion section 1A is caused by environmental and air pollution due to incomplete combustion and fuel consumption is increased.

As another example of the related art, as shown in FIG. 2B, the combustion unit 1B includes a water tank 11b having a plurality of vertical pipes 13b mounted thereon and a combustion chamber 12b formed below the water tank 11b. Main body 10b, a heat insulating material 21b on which a plurality of sound absorbing holes 23b are embedded, an upper cover 20b having a gas outlet 22b, and a combustion chamber zigzag in the lower end of the main body 10b. A baffle 30b on which the plate 31b is mounted so that 12b is formed, and a silencer 40b on which the sound absorbing pipe 41b is mounted to be fitted to the support plate 42b corresponding to the vertical connection 13b of the main body 10b. It is composed of

The combustion unit 1B is a silencer 40b inserted into the vertical pipe 13b of the main body 10b while reflecting the strong combustion sound generated when the fuel is burned by the plate 31b of the baffle 30b. Is first absorbed by the sound absorbing tube 41b and is secondarily absorbed by the sound absorbing hole 23b of the heat insulating material 21b.

In this oil boiler, the heat of combustion is also transmitted to the water tank 11b through the plurality of vertical pipes 13b, and the first and second heat pumps are provided through the sound absorbing pipe 41b of the silencer 40b and the sound absorbing hole 23b of the heat insulating material 21b. It is absorbed by the car, so the thermal efficiency and noise reduction effect are more improved.

However, there was no means for re-burning soot and incompletely burned fuel generated during initial ignition or extinguishing, and thus harmful gases were generated. The sound absorption of the vertical pipe 13b of the main body 10b and the silencer 40b was absorbed. Since the pipe 41b has to be welded one by one, the number of working hours is increased.

In addition, the structure of the vertical pipe 13b of the water tank 11b, the sound absorption pipe 41b of the silencer 40b, the baffle 30b, etc. was complicated by the internal cleaning of the combustion part 113, and was difficult to clean. .

In addition, in order to solve the above problems, a means for recovering combustion heat and waste gas lost from the gas discharge pipe and a recombustion means must be provided, or auxiliary means such as a device for forcibly discharging waste gas for a certain time after extinguishing should be provided. It was a factor in the cost increase.

An object of the present invention is to provide an oil boiler in which the combustion chamber of the combustion section is multistage, and the combustion chambers of each stage are provided with a recombustion means and a noise prevention function, thereby improving combustion efficiency and thermal efficiency and improving noise prevention effect.

Another object of the present invention is to provide a fuel combustion and noise preventing method of an oil boiler in which incomplete combustion fuel and waste gas are completely burned and combustion noise is attenuated step by step to prevent noise from outside.

In order to achieve the above object, in the present invention, a castable ceramic (Castabkle Ceramic) is formed at the bottom of the main body and a baffle having a plate having ceramic fibers (Cermic fiber) is formed in multiple stages. By providing a combustion section of the oil boiler having an upper cover mounted to the.
