Heat-amplified oil combined electric boiler {omitted}

The present invention relates to an electric boiler for thermal amplification oil. More specifically, the heating amplifier (1) has a built-in heat amplifier (2) having a thermal amplification means in the center of the heating boiler (1) and further burned by oil heaters (12, 13). It is installed to be heated through the oil combustion passage pipe (18, 19) by the heat amplification pipe (2) is heated when the gas (he.xe.ar) enclosed therein conducts heat and is heated to a constant temperature As it generates high heat of about 1,200 ℃ during pyrolysis, it is characterized by the fact that the thermal efficiency is much higher than the power consumption and the amount of oil burned, and the thermal efficiency is increased to the maximum by adding a function to increase some thermal efficiency. In the meantime, the constituents are related to a thermally amplified oil-based electric boiler that is manufactured to be practically compact and significantly lowers the heating cost burden than a conventional heating boiler.

Conventionally, it is already known that boilers which combine oil and electricity generally have a structure in which an electric heater is provided to generate heat by receiving electrical energy from a water chamber heated by oil combustion.

Therefore, the oil-combined electric boiler becomes a research subject by efficiently constructing the above structure to increase the thermal efficiency, find a better way to increase the thermal efficiency, reduce the cost and improve the productivity.

In this regard, the prior art Korean Utility Model Registration No. 20-1177114 is not a perfect product.

Therefore has a problem

However, the present invention uses a gas such as he.xe.ar (helium.xenon.argon) that generates high heat when heated to a constant temperature as described above, which is different from the conventional method. It is designed to get higher thermal efficiency, and it has added several functions to increase the thermal efficiency, and the structure is efficiently constructed to maximize the thermal efficiency, and it is manufactured in the smallest practical type in terms of heating cost than the conventional heating boiler. It is to provide a thermally amplified oil combined electric boiler that can significantly reduce the burden.

In addition, the present invention intends to use as a thermal amplification means a gas that generates high heat when heated to a constant temperature to maximize the thermal efficiency as described above. Conventionally, thermal amplification electric boilers have been applied using such a gas. (Utility Model Publication No. 93-6978) Although this thermal amplified electric boiler is a good product that can increase the thermal efficiency, it is very sad that it has not been used much as a boiler.

Therefore, the present invention can be used as a saving oil combined electric boiler rather than a simple electric boiler function, so that oil can be used as a fuel during the day, and midnight electricity can be used at night. The installation of the enclosed thermal amplifier tube and the addition of several functions to further increase the thermal efficiency is to provide an electric boiler with a thermal amplifier.

However, since the present invention uses gas having thermal amplification means for the oil combined electric boiler as described above, it makes up for the problem caused by the new conception and technology development is made for the oil combined electric boiler, and the thermal efficiency is maximized and practical. It is a research task to make a boiler that can be made in the smallest and significantly reduce the heating cost burden than the conventional oil combined electric boiler.

The present invention was devised to achieve the above problems

In order to maximize the thermal efficiency, this paper uses the gas (he.xe.ar) that generates high heat of about 1,200 ℃ while heating up to a certain temperature when heating up to a certain temperature. To reduce the

In the next step, the combustion rate is increased to the maximum when burning the oil of the heating boiler, so that it is close to the complete combustion, so as to prevent soot and increase the thermal efficiency.The next is to reduce the amount of oil burned while burning the oil of the heating boiler. It increases the heat efficiency by increasing the residence time in the boiler.

The next step is to devise measures and methods for recovering the heat that is thrown out of the boiler into the circulating heating water when the smoke with the heat from the boiler is discharged through the flue outside the boiler so that the heating cost can be greatly reduced by reducing the heating cost. The present invention provides a thermally amplified oil-combined electric boiler characterized by the above-mentioned.

Figure 2 is a longitudinal sectional view schematically showing the overall configuration of the present invention.

3 to 13 are explanatory views showing respective parts for understanding the internal structure and the external structure.

The present invention constitutes a main body of a cylindrical heating boiler 1 having one large water tank.

The heating boiler (1) the body is wrapped with a thermal insulation material so that the outside is covered with an outer case (40).

A water tank forming cylinder 29 of the combustion chamber 4 is installed in the lower portion of the main body of the heating boiler 1 so that the heating water 3 is heated by the heat of combustion of the combustion chamber 4, It is installed to prevent loss.

Next, the combustion chamber partition 5 is installed in the combustion chamber 4.

In this way, the installation of the combustion chamber partition 5 will be installed in the combustion passage pipe over the place indicated by the arrow in [Fig. 3], and the up arrow marked places 18, 19, 24, 25, 26, 27 are burned in the combustion chamber 4. Combustion chamber to make a structure in which the flame and the smoke are firstly raised through the first place and the flame and the smoke which are burned to the marked places 20, 21, 22, and 23 are lowered and discharged to the smoke outlet 39. It is to install the partition (5) and to have such a structure is to increase the thermal efficiency because the smoke with the heat that is burned even with a small amount of oil combustion has a long residence time in the boiler.

And the arrows on the angles are mainly arrowheads to help you understand the passage of burned smoke.

And the group of dots on the angle indicates the heating water.

Next, on the combustion chamber 4, as shown in FIG. 5, upward combustion passage pipes 24, 25, 26, and 27 penetrating the water tank 8 and the heating water 3 are installed and opposite to each other. Downward side combustion passage pipes (20, 21, 22, 23) are installed and the combustion passage pipe forming plates (46, 47) up and down around the water tank (8) to serve as a distinction between the combustion passage pipe. And it is installed so as to be able to heat the heating water (3) inside the boiler as a combustion passage pipe.

And the center of the space where the heat amplifier (2) is to be installed, the remaining space is the water tank space, the heating water is filled there.

FIG. 6 is a longitudinal sectional perspective view of a portion of the combustion passage pipe of FIG. 5, which has been communicated through the heating water 3 up and down, and thus shows that the combustion flame and the smoke with heat can pass.

Next, a combustion passage exchange space 7 is provided on the combustion passage tube as shown in FIG.

In order to form the combustion passage space 7, the cylindrical combustion passage space portion forming partitions 30 and 17 having a smaller diameter in the main body water tank are provided inward and outward so that the combustion passage exchange space 7 is formed. do.

Grieg blocks the upper portion of the combustion passage space forming partitions 30 and 17 so that the upper portion of the combustion passage space 7 is filled with heating water 3.

Since the combustion passage exchange space 7 is provided so that the oil is combusted in the combustion chamber 4 of FIG. 3, the combustion chamber partition 5 is provided, so that the upstream combustion passage tube as shown in FIG. Since the flames and smoke burned only at (24, 25, 26, 27) are raised, the combustion passage exchange space (7) is required to descend to the downstream combustion passage tubes (20, 21, 22, 23).

And once the smoke is lowered into the downstream combustion passage pipe is discharged into the year (6) as can be seen in [1] and [2].

In addition, the combustion passage exchange space (7) up, down, left, right. Outside is a water tank (8) and is installed to be filled with heating water (3).

10 is a perspective view showing the water tank and the upper part of the combustion passage as shown in FIG. 9 when cut in half.

Next, the inside of the water tank 8 of the heating boiler was installed with a hot water pipe 37 as shown in FIG. 2 to use hot water.

And the outside of the heating boiler (1) is provided with a flue (6) formed of a double pipe and the combustion smoke is discharged in the inside of the flue (6) and each heating line inside the outer water tank forming pipe (34) of the flue In the first stage, the cold heating water recovered by the circulation pump 10 to the heating inlet 48 is installed so as to be heated by the smoke that is discarded, and the outside water tank forming pipe of the flue 6 is primarily 34. The heating water heated through) is introduced into the water tank (8) of the upper part of the heating boiler (1).

At this time, the outside of the flue (6) water tank forming tube 34 is wrapped with a heat insulating material.

And installed under the flue (6) to install the circulation pump 10 to operate.

In addition, a burner 11 for oil combustion is installed in the burner port 38 in front of the combustion chamber 4, and a combustion heating element 36 is provided in front of the burner port 38 in the combustion chamber 4 as shown in FIG. Since the heating element 36 burns red by the flame coming out of the burner sphere 38, the combustion rate is increased during the combustion of oil, thereby increasing the thermal efficiency and at the same time preventing the occurrence of soot.

In addition, the superheat cut-off sensor 14 and the temperature sensor 15 and the low water level sensor 16 are installed in the heating boiler water tank filled with the heating water 3, as shown in FIGS. 1 and 2. It is connected to send a detection signal to the controller 28 and is also configured to perform each function by the controller 28 and the circulation pump 10 and the oil burner 11 is also installed to be automatically operated by the controller.

In addition, a midnight power switch SW1 is installed, and a general power switch SW2 is also installed to connect to the home AC current.

Next, a heat amplifier tube 2 is installed in the center of the heating boiler 1.

This thermal amplifier tube 2 is shown in detail in FIGS. 11, 12, and 13. The electric heater protection tubes 32 and 33 are installed inside the thermal amplifier tube 2, and the combustion passage tubes 18 and 19 are also installed inside the thermal amplifier tube 2.

In addition, a gas such as he.xe.ar., which generates high heat of about 1,200 ° C. while being pyrolyzed when heated to a constant temperature, is enclosed through the gas injection pipe 31.

And the electric heater protection tube (32, 33) inside the thermal amplifier tube (2) is fixed by putting the nichrome wire (12, 13), which is a hot wire closely wound to the quartz glass tube (44) as shown in FIG. At this time, in order to fix the quartz glass tube and the nichrome wire from moving, the fixing insulator 41 is attached to the upper and lower portions of the quartz glass tube 44 and fixed with the electric heater plug 42 for fixing the glass quartz tube 44 thereon. do

Thus, the electric heater protection pipes 32 and 33 installed next to each other and the nichrome wires 12 and 13, which are heating wires installed therein, are prevented from coming into contact with the electric heater protection pipes 32 and 33 to prevent a short circuit. It is installed so that heat can be transferred well. Also, it is installed to facilitate the troubleshooting during use by inserting and removing the coiled quartz glass tube 44, which is wound around the quartz glass tube 44. Nichrome wires 12 and 13 are operated by electric heaters.

The electric heaters 12 and 13 are installed inside the thermal amplification pipe 2 in order to heat the gas enclosed in the thermal amplification pipe 2, and the gas subjected to the heating is about 1,200 DEG C while thermally decomposed when heated. This is because the direct electric heaters 12 and 13 are more effective than heating the heating water because they are used to heat the heating water 3 next to them because they generate high heat.

In addition, the installation of the combustion passage tubes 18 and 19 inside the thermal amplification tube 2 is because the combustion of the flame and the heat with the combustion of the combustion passage pipes 18 and 19 through the combustion passage tube 18 and 19 passes the thermal amplification. It heats the gas enclosed in the inside of the pipe (2). When this gas is heated, it generates high heat of about 1,200 ℃ while pyrolyzing, so it can be used to heat the heating water (3) next to it. Since gas is more effective than heating (3) and heat efficiency can be increased, gas with thermal amplification means is used.

In this way, the electric heaters 12 and 13 are also heated through the combustion passage tubes 18 and 19 by oil combustion, so that the power consumed by the thermal amplification means of the heat amplifier 2 is also compared with the amount of oil consumption burned. Since it is possible to obtain an extremely high amount of heat, a gas such as he.xe.ar. may be enclosed in the heat amplifier tube 2 and heated.

The heating boiler 1 having the above-described structure has a superheat cutoff sensor 14, a temperature sensor 15, a low water level sensor 16, and a circulation pump that are automatically controlled and operated by the controller 28. (10) and oil burners are installed respectively and each function is performed.

Therefore, if the general power switch SW2 is operated during the day, the electric heaters 12 and 13 are not operated, but the heating water 3 inside the heating boiler 1 is lower than the set temperature set in the boiler controller 28. When the oil burner (11) is operated to blow oil and air into the combustion chamber (4) and automatically ignite the combustion heater (36) installed in front of the burner opening (38) as shown in FIG. First, it heats up and heats up red, thereby accelerating oil combustion, thereby reducing soot generation and increasing thermal efficiency.

The combustion flame and the smoke having the heat are caused by the combustion chamber partition 5 installed inside the combustion chamber 4, so that the upper side combustion passage tubes 24, 25, 26, 27 as shown in Figs. ) And only the combustion passage pipes (18, 19) inside the thermal amplification pipe (2), and this risen smoke passes downward through the combustion passage exchange space (7) (20, 21, 22, 23). ) Is moved downward and discharged out through the outer flue 6 through the rear space portion of the combustion chamber partition 5.

In this way, the upward and downward combustion of the smoke from inside of the boiler is discharged to increase the thermal efficiency of the flame and the smoke with the heat, which increases the residence time in the boiler.

In addition, when the burned smoke passes through the combustion passage tubes 18 and 19 inside the thermal amplifier tube 2, the gas encapsulated in the thermal amplifier tube 2 is heated to a constant temperature and thermally decomposed to about 1,200 ° C. Since it generates high heat, it heats the heating water (3) inside the boiler. Therefore, it is possible to obtain a much higher amount of heat than the amount of oil burned.

The heating water 3 heated through this process is circulated by the set temperature set in the controller 28 when the temperature sensor 15 attached to the inside of the boiler senses the temperature and sends a signal to the controller 28. The pump 10 is operated so that the heating water heated by the oil combustion inside the boiler and by the thermal amplification means is supplied to each heating line through the boiler heating water outlet 9 and circulated to achieve heating.

At this time, the heating water 3 circulated by the circulation pump 10 is supplied to a heating line (not shown) and the cold heating water recovered through the heating inlet 48 in the heating line is shown in FIGS. 2] through the inside of the flue water tank forming pipe 34 of the flue 6 is introduced into the boiler and circulated. Thus, the flue 6 is formed into a double pipe so that the flue water tank forming pipe 34 is inside. Passing the cold heating water recovered into the furnace causes the flue gas with the burned heat to be discharged out through the flue (6) so that the cold heating water circulated through the smoke of the flue (6) that is thrown away is primarily heated. It is to be introduced into the boiler through the upper side of the to increase the significant thermal efficiency.

When the night power switch (SW1) is operated at night, the controller 28 stops the burner at the time when the midnight electricity is supplied, and at the same time, the electric heaters 12 and 13 inside the thermal amplifier tube 2 are automatically turned on. It is activated. When the electric heater is heated to a constant temperature by the operation of the electric heater, the enclosed gas (he.xe.ar) inside the heat amplifier tube 2 next to it receives heat and is heated to a constant temperature to pyrolyze about 1,200. This amplified high temperature heats the heating water 3 inside the boiler water tank right next to it, and the heating water started to be heated by the temperature sensor when the set temperature set in the controller 28 is reached. The sensed temperature is transmitted to the controller 28 as a signal so that the circulation pump 10 is operated by the controller 28 so that the heated heating water inside the heating boiler 1 is circulated through the heating outlet 9 and heated. It is fed to the line and heated. As described above, the gas such as he.xe.ar. (helium.xenon.argon) encapsulated inside the thermal amplification tube 2 is thermally decomposed when heated to generate high heat of about 1,200 ° C. This paper can make a boiler with better heat efficiency than conventional oil-based electric boilers.

Next, an overheat protection circuit is installed to block the risk of overheating of the burner by the electric heater in this paper.When the overheat protection circuit is activated, the electric supply of the electric heaters 12 and 13 can be automatically cut off. To be installed. It is also installed to stop the burner.

Next, as shown in FIG. 4, the smoke outlet 39 is installed at the left and right sides, and can be selectively used as needed.

In addition, the heating export opening (9) is installed on the left and right so that it can be selectively used as needed.

As described above, the present invention encloses a gas having a thermal amplification means inside the heating boiler 1, compared to electric power consumed by installing the thermal amplification pipe 2 by an electric heater and by heating the oil. In addition, it is a heat-amplified oil combined electric boiler, characterized in that it is possible to obtain a significantly higher calorie value than the amount of oil burned.

In addition, during the combustion of oil, a spring-type combustion heating element 36 was installed in front of the burner port inside the combustion chamber 4 to improve the oil combustion rate, and at the same time, greatly reduce the occurrence of oil soot, thereby improving thermal efficiency.

Next, a combustion chamber partition is installed in the oil combustion chamber 4 so that the burned flame and the smoke with heat are raised to the upstream combustion passage pipe and down to the opposite downstream combustion passage pipe to be discharged to the flue 6. Thus, even with a small amount of oil combustion, the combustion time with the flame and heat of combustion is increased in the boiler to increase the thermal efficiency.

Next, the flue (6) is formed into a double pipe to pass the cold heating water recovered by the circulation pump into the flue water tank forming pipe (34) so that it can be primarily heated so that thermal efficiency can be improved by the discarded smoke. It is a boiler.

As the above-described thermal amplification oil combined electric boiler with the characteristics of several thermal efficiency as described above, it has a significant energy saving effect and can reduce the heating cost burden of each user, and also because the combustion heating element 36 is installed, the combustion rate is increased. It also increases the effect of preventing air pollution caused by smoke.
