EMBODIMENT OF THE INVENTION Hereinafter, the energy-saving eco-friendly steam boiler system of this invention is demonstrated, referring drawings for based on the preferable embodiment.

The energy-saving eco-friendly steam boiler system 1 of the present invention is basically a steam boiler 1a, a burner 11, a heat exchanger 12, a condensate tank 13, a high temperature pump 14, as shown in FIG. ), Pump 15, conduits 16, 17, 18, 19.

A schematic operation of the energy-saving eco-friendly steam boiler system 1 of the present invention will be described with reference to FIG. 1.

First, when saturated steam is made inside the steam boiler 1a, the saturated steam enters the heat exchanger 12 through the conduit 16. At the same time, when the tap water (or ground water) enters the heat exchanger 12 through the conduit 17, it exchanges heat with saturated steam, and the tap water (or ground water) becomes hot water of 98 degrees Celsius and enters the storage tank. Saturated steam is condensed to the same temperature while maintaining the temperature entered into the heat exchanger (12) and transported to the condensate tank (13), hot condensate from the condensate tank (13) again enters the steam boiler (1a) and saturated steam in an instant This saturated steam is again introduced into the heat exchanger 12 through the conduit (16).

More specific operation of the energy-saving eco-friendly steam boiler system 1 of the present invention will be described with reference to FIG. 2.

First, saturated steam with a temperature of 147.6 degrees Celsius (297.68 degrees Fahrenheit) and a steam pressure of 340 kPa (50 psig) at the gauge pressure exits the steam boiler (1a) and enters the heat exchanger (12) through conduit (16), at the same time Tap water (or ground water) of 10 to 20 degrees enters the tap water (or ground water) inflow path 17a and enters the heat exchanger 12 through the conduit 17 and the pump 15.

Heat exchange between the saturated steam and the tap water (or ground water) in the heat exchanger 12 is subsequently carried out and the saturated steam moves to the condensate tank 13 through the conduit 18, the saturated steam (including the condensate) exiting the heat exchanger 12 ) Is 147.6 degrees Celsius (297.68 degrees Fahrenheit) the same as when entering the heat exchanger 12, the temperature of the tap water (or groundwater) exiting the heat exchanger 12 will change to 97.78 degrees Celsius (208 degrees Fahrenheit). .
That is, heat is exchanged between the saturated steam and the tap water (or ground water) in the heat exchanger 12, and the temperature of the saturated steam is maintained at that temperature without any change in temperature even after heat exchange with water. Will be moved to).
In addition, the present invention may further add a thermostat device to adjust the temperature desired by the user. Hot water of 60 ~ 80 ℃ is enough for home use, so there is no need to waste energy to raise the temperature higher than necessary. It can be used.

As such, the temperature values of the steam inlet and the outlet of the heat exchanger 12 are equal to each other so that the saturated steam, which is the heat medium in the heat exchanger 12, changes phase into condensed water without changing the vapor pressure, and thus the latent heat ( Only latent heat is used to heat tap water (or ground water). In this case, it is considered that no temperature reduction such as de-superheating or sub-cooling of steam occurs.

Hot water of 97.78 degrees Celsius (208 degrees Fahrenheit) heated in the heat exchanger 12 is supplied to a hot water storage tank (not shown) for use by us through conduit 19, hot pump 14, and hot water outlet 19a. Stored.

 On the other hand, saturated steam entering the heat exchanger 12 exchanges heat with tap water (or groundwater). The temperature of the saturated steam, that is, 147.6 degrees Celsius (297.68 degrees Fahrenheit), remains unchanged even after heat exchange with water. It is stored in the condensate tank 13 while maintaining.

In addition, when the condensate pump 20 is commanded to the condensate pump 20 between the condensate tank 13 and the boiler inlet path 20a of the condensate in the boiler control box (not shown), the condensate in the condensate tank 13 is steam boiler ( 1a) will be transported into.

In this way, the saturated steam produced in the steam boiler 1a enters the heat exchanger 12 and exchanges heat with water. The condensate tank 13 is then transferred to the condensate tank 13 while maintaining the same temperature. This process occurs in a saturated steam, which is repeated without interruption quickly.

This process does not take much energy to convert hot condensate into saturated steam.

The operation of the energy-saving eco-friendly steam boiler system 1 according to the present invention will be described with reference to FIGS. 3A and 3B which disclose the internal structure of the steam boiler 1a according to the present invention in detail.

The steam boiler 1a according to the present invention is an upright boiler, which introduces fuel gas into the burner 11 through the fuel gas inlet path 21, and atmospheric air is also required into the burner 11 by the blower 22. When the fuel gas is ignited by the amount, the burner 11 fires a flame into the combustion chamber 23. The coil 24 in the combustion chamber 23 is heated, and condensed water in the coil 24 is heated to generate saturated steam. Done. The generated saturated steam then enters heat exchanger 12 through conduit 16.

When the burner 11 shoots a flame in the combustion chamber 23, the condensate in the coil 24 becomes saturated steam, while contaminants from the flame are removed by the washing water in the washing water tank 25, and the contaminated washing water is hot. After being filtered into the filtration tank 27 by the pump 26, the waste heat recovery 28 is preheated and then returned to the washing water tank 25 again.

Tap water (or groundwater) preheated in the waste heat recovery 28 is preheated again in the water tank 36 surrounding the combustion chamber 23.

At this time, the washing water is boiled due to the flame from the combustion chamber 23, and the water level 29 of the washing water to which the pressure of the flame is directly applied is lower than that of the surrounding washing water 30 to which the pressure of the flame is not directly applied.

 Meanwhile, when the air injected by the blower 22 enters the washing water tank 25 together with the flame of the burner 11, the air is purged by the washing water and turned into air bubbles by the pressure in the washing water tank 25 to the steam separator 32. At this time, a part of the washing liquid turns into water vapor by heat and enters together.

The polluted air purified by steam and washing water enters the steam separator 32 with heat and is separated into air and steam, while the heated air passes through the air outlet 33 and is installed in the water tank 36. Out of the (31) while preheating the tap water (or ground water) in the water tank 36, the separated water vapor (turned into a liquid) is recovered by the pump 35 to the wash water tank (25).

And from the moment the flame is burned in the burner 11, this process is repeated.

As described above, saturated steam is produced in the coil 24 inside the steam boiler 1a. The temperature is 147.6 degrees Celsius (297.68 degrees Fahrenheit), and the saturated steam at this high temperature is 340 kPa (50 psig) at the gauge pressure. Enters the heat exchanger (12).

When saturated steam exits the coil 24 inside the steam boiler 1a and enters the heat exchanger 12, the tap water (or ground water) stored and preheated in the water tank 36 is also heated by the hot pump 37. Go in and out of (12).

At the same time that tap water (or groundwater) pumped by the hot pump 37 enters the heat exchanger 12 and is discharged to the hot water outlet 19a, through the saturated steam inlet 16a and the condensate recovery path 18a. The temperature of the saturated steam entering and exiting the heat exchanger 12 is 147.6 degrees Celsius (297.68 degrees Fahrenheit), and the temperature of the tap water (or groundwater) heat exchanged from the saturated steam is changed to 97.78 degrees Celsius (208 degrees Fahrenheit).

The hot water of 97.78 degrees Celsius (208 degrees Fahrenheit) is discharged to the hot water outlet 19a by the hot pump 14 and finally stored in a hot water storage tank (not shown) which we can use.

The saturated steam entering the heat exchanger 12 exchanges heat with tap water (or groundwater). The temperature of the saturated steam, that is, 147.6 degrees Celsius (297.68 degrees F.), remains unchanged even after heat exchange with water. While stored in the condensate tank (13).

When the gauge pressure of saturated steam entering and exiting the heat exchanger 12 is lowered below 340 kPa (50 psig), the temperature of the saturated steam is lower than 147.6 degrees Celsius (297.68 degrees Fahrenheit) to obtain 97.78 degrees Celsius (208 degrees Fahrenheit). If the gauge pressure of the saturated steam is higher than that, the heat exchanger 12 may be damaged.

And when the condensate pump (not shown) in the boiler control box (not shown) to the condensate pump (not shown) between the condensate tank 13 and the boiler inlet (20a) of the condensate water condensate in the condensate tank (13) steam boiler It is transferred into the coil 24 in (1a).

In this way, the saturated steam produced in the steam boiler 1a enters the heat exchanger 12 and exchanges heat with water. The condensate tank 13 is then transferred to the condensate tank 13 while maintaining the same temperature. This process occurs in a saturated steam, which is repeated without interruption quickly.

This process does not take much energy to convert hot condensate into saturated steam.

The heat exchanger 12 according to the present invention is a gasket flat plate type heat exchanger and is composed of thin corrugated boards for transferring heat between the fluid and the fluid.

These flat plates are filled with gaps around the ports and edges to form a narrow gap through which fluids flow.

The heat exchanger 12 allows cold fluids to pass odd-numbered gaps and hot fluids to even-numbered gaps so that the two fluids do not mix anywhere inside the heat exchanger 12. Is designed.

By this design, each gap through which hot fluid flows is in contact with the cold fluid with the flat plates interposed therebetween, and the hot fluid flows through the gap and the plates of each part When you heat a flat plate, the flat plates heat up the cold liquid on the other side.

Cold fluid, on the other hand, cools the flat plates on both sides as it flows through the gap, and the flat plates cool the opposite hot fluid.

 Since it is common for the heat exchanger 12 to allow hot and cold fluids to flow in opposite directions, the temperature at which the hot fluid exits the heat exchanger 12 is determined by the temperature at which the cold fluid enters the heat exchanger 12. It is close to the temperature and vice versa.

In this way, the heat exchanger 12 according to the present invention almost completely exchanges the thermal energy of the fluids without any contact or mixing between the two types of fluids.

With regard to saturated steam, steam is generally a very powerful fluid.

At 69 kPa (10 psi), one kilogram of steam occupies more than 2000 times the space of one kilogram of water, and the heat released by condensing one kilogram of steam is about five times that of changing from one kilogram of water to a boiling point.

For this reason, steam is a great way to heat objects, and combining the efficiency of a gasket flat plate heat exchanger with the power of steam is a very useful way to get hot water quickly and easily.

One of the more complicated and interesting facts about condensed steam is that the temperature remains the same even during the condensation of all steam.

This occurs because the energy of the steam is used to convert the vapor of the gas into liquid water at the same temperature until all the steam has condensed.

This is why the same temperature of water leaves the heat exchanger 12 when steam enters.

The cold water inside the heat exchanger is heated by the thermal energy provided by the condensation of steam.

For example, when ice cubes are put in a coca-cola in a cup, the liquid coca-cola takes heat away from the ice and cools, but the temperature of the floating solid ice never changes.

Energy-saving eco-friendly steam boiler system 1 of the present invention is provided with a fuel gas activation device to increase the combustion efficiency of the fuel gas and reduce environmental pollutants generated during the combustion process.

The fuel gas activator 100 is installed in a portion of the fuel gas inlet 21 as shown in FIG. 4A, and the housing 101 has a portion of the fuel gas inlet 21 and the permanent magnets 102a and 102b. It is configured to surround.

The housing 101 is composed of two hemispherical halves connected to each other by screws 103 to facilitate installation or removal of the fuel gas activator 100.

The housing 101 is made of a nonmagnetic material such as aluminum.

In addition, the fuel gas activator 100 may have a core material that can replace a part of the thickness of the housing 101 inside each of the housing 101 half portions between the housing 101 and the fuel gas inlet passage 21. The core material may be made of a polymer such as polystyrene.

In addition, a plurality of permanent magnet settling grooves 103a and 103b for accommodating a plurality of permanent magnets 102a and 102b are formed in the core of the housing 101 half, and a plurality of permanent magnets are provided in the core of the other half of the housing 101. Positioning the permanent magnets 102a and 102b by protruding the magnets 102a and 102b and inserting the plurality of permanent magnets 102a and 102b into the plurality of permanent magnet settling grooves 103a and 103b as plugs. Keep it.

4A, at least one permanent magnet 102a is arranged on the first side of a part of the fuel gas inlet 21 in the longitudinal direction of the fuel gas inlet 21. One or more other permanent magnets 102b are disposed in the longitudinal direction of the fuel gas inlet 21 on one side and a second side of the portion of the fuel gas inlet 21 that is opposite in the radial direction of the fuel gas inlet 21. Are arranged in alignment.

Here, the polarity of the at least one permanent magnet 102a disposed on the first side is the same as the polarity of the permanent magnet 102b disposed on the second side.

The one or more permanent magnets 102a of the first side are also two longitudinally aligned permanent magnets arranged so that the ends of opposite polarities face each other, and the one or more permanent magnets 102b of the second side also have opposite polarities. Two or more longitudinally aligned permanent magnets arranged such that the ends of the two face each other.

When a fuel gas or other combustibles such as natural gas flows through a portion of the fuel gas inlet passage 21 surrounded by the fuel gas activator 100, a magnetic field is applied to the fuel gas or other combustibles such as natural gas to form a molecular structure. The negative combustion effect of the sulfur component mixed with the fuel gas, etc. is reduced and thus, a more complete and efficient combustion of the fuel gas supplied to the burner 11 can be achieved, as well as combustion of the fuel gas. Environmental pollutants may also be reduced.

In an exemplary embodiment of the fuel gas activator 100, the housing 101 has a length of 10.16 cm (4 inches), a width of 5.08 cm (2 inches), and a thickness of 1.905 cm (0.75 inches).

Permanent magnets 102a and 102b have a length of 2.54 cm (1 inch), a width of 0.635 cm (0.25 inch) and a thickness of 1.27 cm (0.5 inch).

Each of the permanent magnets 102a and 102b is disposed at a distance of 1.905 cm (3/4 inch) from the end of each other in the longitudinal direction of the housing 101.

The permanent magnets 102a and 102b are 2000 Gaussian neodymium magnets.

The number, size, and arrangement of the permanent magnets 102a and 102b may vary depending on the dimensions and other factors of the fuel gas inlet passage 21. For example, using strong magnets allows the use of fewer magnets and allows the magnets to be spaced farther apart.

For the purposes of this application, the term “conduit” refers to a component for transferring fluid from one point to another. Conduits may consist of a single pipe or tube, multiple pipes or tubes, and other devices used to transfer pipes, tubes, elbows, joints, or fluids from one point to another.

4d illustrates a conduit type fuel gas activation device 100 installed in the energy-saving eco-friendly steam boiler system 1 of the present invention. In FIG. 4D, the A conduit method consists of four pipes, four fuel gas activation devices 100, and four elbows, and the B conduit method consists of four fuel gas activation devices 100 and four pipes.

And the energy-saving eco-friendly steam boiler system of the present invention can use natural gas, diesel, petroleum, bunker C oil as fuel.

In addition, the energy-saving eco-friendly steam boiler system 1 of the present invention is an air activation device 200 in the air inlet path 201 of the inlet of the blower 22 to increase the combustion efficiency of fuel gas and reduce environmental pollutants generated in the combustion process. Can be installed by adding

The air activation device 200 includes a plurality of permanent magnets 202a and 202b surrounding the air inlet passage 201 as shown in FIG. 5A.

The polarity of the permanent magnet 202a on one side in the radial direction of the air inflow path 201 is the same as the polarity of the permanent magnet 202 on the other side in the radial direction of the opposite air inflow path 201. Air enters directly from the atmosphere at one side of the air inlet 201 or through a conduit or an air filter, and passes through the air inlet 201 in which the air activator 200 is installed. It goes out to the side and is used for the combustion of the fuel gas supplied to the boiler by the fuel gas inflow path 21.

When the air activator 200 is used, a magnetic field is applied to air (20% oxygen and 80% nitrogen) that is sucked into the boiler to induce a regular arrangement of the air molecular structure, and thus the fuel gas inlet 21 By this, not only a more complete and efficient combustion of the fuel gas supplied to the burner 11 can be achieved, but also environmental pollutants caused by the combustion of the fuel gas can be reduced.

In an exemplary embodiment of the air activation device 200, the air inlet path 201 has a diameter of 1,905 cm (3/4 inch). Permanent magnet 202 is 5.08 cm (2 inches) long, 2.54 cm (1 inch) wide, 1.27 cm (1/2 inch) thick, with three or four permanent magnets 202 in the air It is arranged on each side of the air inlet passage 201 opposed to each other in the radial direction of the furnace (201).

The permanent magnets 202 are separated from each other by a distance of 1.905 cm (3/4 inch), and use 2000 Gaussian neodymium magnets, and the number, size, and arrangement of the magnets are different from the dimensions of the air inlet 201. It may vary. For example, using strong magnets allows the use of fewer magnets and allows the magnets to be spaced farther apart.

Most burners currently on the market are difficult to burn completely, so the combustion rate is reduced by about 15%. When the fuel gas activating device 100 and the air activating device 200 according to the present invention are used, complete combustion is possible, and among the environmental pollutants In particular, it is possible to completely remove the carbon monoxide harmful to the human body, and also reduce the maintenance cost of the boiler by reducing the occurrence of scale generated in the combustion section and the combustion gas discharge portion of the boiler by incomplete combustion.

The results of analyzing the combustion gas using the fuel gas activating apparatus 100 and the air activating apparatus 200 according to the present invention in conventional steam boilers are shown in Table 1 below.

As can be seen in Table 1, the fuel gas activating apparatus 100 and the air activating apparatus 200 according to the present invention can burn fuel gas without generating carbon monoxide.

Interesting facts with respect to the present invention is that if the conventional steam boiler on the market to install the upgrade kit 300 using the principle of the energy-saving eco-friendly steam boiler system (1) of the present invention can greatly improve the thermal efficiency of the boiler will be.

That is, when the saturated steam generated in the conventional steam boiler enters the upgrade kit 300 according to the present invention, it is possible to obtain almost the same amount of hot water as the energy-saving eco-friendly steam boiler system 1 of the present invention. The advantage of the upgrade kit 300 is that the thermal efficiency can be greatly improved, the life of the boiler is extended, and above all, the upgraded cost can be returned within 18 months by significantly reducing the energy cost.

Upgrade kit 300 is packaged by removing the heat exchanger and the condenser of the energy-saving eco-friendly steam boiler system 1 of the present invention, the operation will be described with reference to Figure 6a and 6b as follows.

First, saturated steam exits a conventional steam boiler and enters the gasket flat plate heat exchanger 302 via a steam injection furnace 301 at a temperature of 147.6 degrees Celsius (297.68 degrees Fahrenheit) and a steam pressure of 340 kPa (50 psig). .

When saturated steam enters the gasket flat plate heat exchanger 302 through the steam inlet 301, at the same time the gasket flat plate through the tap or groundwater tap water (or ground water) inlet 303 and the pump 304 Enter heat exchanger 302.

Then, the tap water or ground water heated by the saturated steam in the gasket flat plate heat exchanger 302 is changed to 97.78 degrees Celsius (208 degrees Fahrenheit), and is moved to the hot water outlet 306 by the hot water pump 305. It is stored in a storage tank that we can use.

On the other hand, the saturated steam, which supplies heat to the tap water or groundwater and condenses the gasket flat plate heat exchanger 302, is maintained at 147.6 degrees Celsius (297.68 degrees Fahrenheit) without a change in temperature, through the condensate recovery path 307. 308 is stored.

In addition, when the condensate pump 310 is commanded to the condensate pump 310 between the condensate tank 308 and the boiler inlet 309 of the condensate in the boiler control box (not shown), the condensed water in the condensate tank 308 may be steam boiler ( 1a) will be transported into.

Thus, the saturated steam produced in the steam boiler 1a enters and exits the gasket flat plate heat exchanger 302 to exchange heat with water. Saturated steam is sent back in, and this process is repeated repeatedly without interruption.

This process does not take much energy to convert hot condensate into saturated steam.

Upgrading the conventional steam boiler to the upgrade kit 300 according to the present invention has almost the same effect as the energy-saving eco-friendly steam boiler system of the present invention without replacing the boiler. In addition, the installation of the above-described fuel gas activator or air activator or the use of low-nox burner (NOx 25ppm) can greatly contribute to environmental protection.

The thermodynamic data obtained as a result of operating the boiler by applying the upgrade kit 300 according to the present invention to a conventional steam boiler on the market is shown in Table 2 below.

In Table 2, boiler A is for a conventional (associated) steam boiler (2.5 tons / 150 hp), boiler B is to attach the upgrade kit 300 to boiler A.

Boiler A makes hot water by directly contacting the steam in the steam chamber with the water (20 degrees Celsius) of the separate water tank. The steam in the steam chamber is mixed with the water in the water tank and cannot be recovered. When the heat exchange was performed and the water in the water tank was 98 degrees Celsius, it was operated by a batch operation in which the steam flow path was changed to another water tank and the water of 20 degrees Celsius was made into hot water again.

Boiler B sends the steam of Boiler A to the gasket flat plate heat exchanger 302 of the upgrade kit 300 to exchange heat with the continuously transported water (20 degrees Celsius), and the produced hot water (98 degrees Celsius) passes through the conduit. Continuously exiting the gasket flat plate heat exchanger 302, at the same time condensate condensed at the same temperature as the steam in the steam chamber exits the gasket flat plate heat exchanger 302 is continuously recovered to the steam chamber of the boiler continuous heat exchange It was operated by a formula operation.

And the boiler A and B set the heat input amount and the temperature conditions of the water which flows in and out similarly.

As a result, approximately 4,500 kg of hot water is obtained in Boiler A, approximately 16,000 kg of hot water is obtained in Boiler B, and boiler B equipped with the upgrade kit 300 according to the present invention is conventional (associated) boiler A. It can be confirmed that it has about 4 times the hot water production capacity.

Boiler C1 ~ C5 (ESEI-1 ~ ESEI-5) is for the energy-saving eco-friendly steam boiler system of the present invention, hot water production capacity (16,000kg) of boiler B equipped with an upgrade kit 300 in conventional (associated) boiler A / hr) is equivalent to the hot water production capacity (16,262kg / hr) of boiler C3 (ESEI-3) of the same specifications (150 horsepower).

As described above, the energy-saving eco-friendly steam boiler system uses only the condensation latent heat of saturated steam made in a steam boiler as a heat source for manufacturing hot water, and the saturated steam is circulated through a closed circuit, thus losing steam produced in a steam boiler. It does not require much energy to regenerate condensate water at the same temperature as saturated steam again to saturated steam, so it has a greater effect than conventional boilers in terms of energy saving.

In addition, the energy-saving eco-friendly steam boiler system of the present invention is a conventional boiler (linked boiler, water pipe boiler) by heating the low temperature water to make steam, the steam boiler system of the present invention condensed at the same temperature as the steam temperature Since the condensed water is regenerated into steam again, the steam regeneration rate is high, and by using a gasket flat plate heat exchanger having excellent heat exchange performance, the hourly production of hot water is also greatly increased to match the large regeneration rate of steam.

In addition, the energy-saving eco-friendly steam boiler system of the present invention not only has a low energy loss and a high steam production rate, but also puts water to be converted into steam in the body of the boiler, such as a conventional boiler (pipe-type boiler, water tube boiler), or There is no need to install the pipes to pass through, so the size of the boiler can be greatly reduced, thereby reducing the installation area and manufacturing cost of the device.

In addition, the energy-saving eco-friendly steam boiler system of the present invention is capable of complete combustion of fuel by introduction of a fuel activator and an air activator. It has the effect of providing a steam boiler.
