Description

Combination heating system using combustion catalyst burner and electric heater

The present invention relates to a composite heating system using a catalytic burner for combustion and an electric heater, wherein an electric heater is mounted on the upper part of the catalytic combustion burner so that electricity and gas can be used alone or in combination.

In general, various types of burners (heating device or combustion device) have been devised and used, but most depend on the direct heating method using a flame to directly heat the heating object (eg, livestock and fishery products or its food). Not only does it not cook evenly, but there is a problem that the surface of these heating objects burns easily, so proximity heating is virtually impossible.

Therefore, since the heating object is heated by a distance that does not burn or is not pressed, it takes a lot of heating time, wastes a lot of energy, so the overall thermal efficiency decreases, and there is a problem that the room needs to be ventilated frequently because of the large amount of air consumed for combustion.

In addition, in the case of a heating device using an alumina (ceramic) mat that generates far infrared rays, there is an advantage that proximity heating is possible by far infrared rays. There is an environmental hazard that pollutes while flying into the surrounding space, and it is unsanitary, so it is inappropriate to use it as a food roaster (food cooker).

In addition, there is a heating device configured to generate a large amount of infrared light by heating a ceramic (alumina) plate with a high temperature flame of 1,000 ° C or higher, but the eyes are irritated by the action of NO _X , which is mainly generated at a high temperature of 1,000 ° C or higher. There is a problem that air is polluted, and the place close to the heat source is hot, and when the distance from the heat source is farther away, the heat deviation is large, which causes the heating temperature to drop significantly, resulting in poor thermal efficiency. There is a problem.

1 illustrates a conventionally used catalyst burner for combustion, in which a heat-resistant chamber 1 with an open upper portion, a combustion catalyst 2 is installed on the upper chamber 1, and a heat insulating material layer 3 on the lower portion thereof. is installed, the electric heater 4 is installed inside the heat insulating material layer 3, the heat insulating material 5 is installed under the heat insulating material layer 3, and the gas diffusion chamber 6 is installed under the heat insulating material 5 Detects the temperature of the gas supply pipe 9 and the combustion catalyst 2 having an on/off valve 8 formed on one side of the chamber 1 to supply and block the fuel gas 7 to the gas diffusion chamber 6 It is configured to include a temperature sensor 10 and a controller.

In the case of the above-mentioned conventional catalyst burner for combustion, the catalyst burner is used alone, and the electric heater 4 mounted inside the combustion catalyst 2 serves to increase the reaction starting temperature of the combustion catalyst and is turned off after that, for example, Since it is used only for ignition purposes, the efficiency is low, and since the combustion catalyst 2 is subjected to heat stress in the OFF state while it is operating, there is a problem in that durability and efficiency are reduced and the service life is shortened.

In addition, the durability of the electric heater (4) built into the combustion catalyst (2) is short due to the fuel gas (7) inside the combustion catalyst burner and moisture generated by the catalytic reaction, and the electric heater uses the fuel gas (7) There is a risk of internal explosion in direct contact with

In addition, the conventional catalyst burner for combustion dries the heating object (the object to be heated) by a low-temperature flameless far-infrared radiant heat method using only the fuel gas 7, but it has a disadvantage that it takes a lot of time to dry as a whole due to the low temperature.

On the other hand, in the case of a conventionally used flame generating gas burner, a large amount of harmful substances and NOx are generated during incomplete combustion due to the generation of a high-temperature flame. there is.

In addition, in the case of an electric burner (electric heater) that uses an electric heater alone, it is advantageous to dry the surface of the heating object with high-temperature infrared heat, but there is a limit to the internal heating of the heating object (heated object), and the surface is burned before the inside is cooked. There were several problems such as deterioration of the quality of heating products and deterioration of durability of electric heaters.

In the present invention, the combustion catalyst 12 is kept constant at a set temperature in the range of 250 ° C to 450 ° C by the setting unit S and the mat temperature sensor 21, and generates a relatively low temperature of about 250 ° C to 450 ° C. It is safe against fire and generates far-infrared rays with uniform heat and deep heat penetration.

In the present invention, moisture contained in the fuel gas 17 is naturally raised and vaporized by the heat of 250° C. to 450° C. by the combustion catalyst 12 and the secondary heat by the electric heater 14, so the reaction with the fuel gas 17 explosion is prevented, and also the efficiency reduction and shortening of the life of the combustion catalyst 12 and the electric heater 14 are prevented.

In addition, in the present invention, since vaporization is greatly accelerated and organic matter decomposition ability is very excellent, odor is quickly deodorized. That is, the combustion catalyst 12 coated with the noble metal catalyst and tourmaline is activated so that harmful organic substances or unpleasant odors, such as odor, fishy smell, fish burn, chemicals, smoke, etc. contained in the updraft are quickly removed in a harmless state. decomposed and removed

And, in the present invention, the gentle vaporization of moisture is promoted by the electric energy naturally generated from tourmaline. Far-infrared rays and negative ions, which are generated like the vaporization of moisture, act, making it more subtle and natural.

In addition, existing heating devices have problems such as burning or burning when a heating object (food) is close to it, and a significant decrease in heating efficiency when it is a little off, requires a lot of maintenance cost, and generates a large amount of unburned material during initial ignition, which causes eye irritation. Although there were problems such as having to ventilate frequently, these problems are eliminated in the present invention.

The combustion catalyst 12 may be a flameless silica mat using a noble metal and a tourmaline catalyst. The flameless silica mat generates a large amount of far infrared rays and anions. Since the silica (SiO2) has a small surface area, it is very disadvantageous for catalyst coating. Therefore, in the present invention, the noble metal catalyst coating becomes easy by greatly expanding the surface area of the silica mat through the pretreatment process.

In the combustion catalyst 12 of the present invention, the combustion efficiency in the combustion catalyst 12 is improved by activating and using fuel gas 17 such as LPG, LNG, butane, hydrogen gas, liquid petroleum fuel, and far infrared rays and negative ions. The effect is doubled, and in particular, when various grilled foods such as jerky are baked, the smell of food is deodorized and removed.

By exemplifying the advantages of applying the heating object 29 to the roasting with the composite heating system (A) of the present invention, since the cooked food to be heated does not burn because it is baked with a flameless method far infrared rays, proximity heating is possible and energy is saved. The effect of far-infrared rays can be maximized, the volatilization of the juice of the food is minimized by the moisture generated from the fuel gas 17, the oil is evenly spread, and the original taste of the food is maintained. It is cooked as food, and since the temperature of the combustion catalyst 12 can be variously adjusted according to the type and condition of the food and the preferences of consumers, it is possible not only to drastically reduce the fuel cost, but also to significantly improve the heating quality.

As the heating object 29 in the present invention, in the case of food, various agricultural products and meat, including semi-dried, dried, and non-dried aquatic products including saury, mackerel, squid, Korean chives, pidegi, and fish cakes, etc. are included.

On the other hand, the conventional direct-fired heating device made of a ceramic (alumina) material is unsanitary, such as flying powder and generating dust, but the composite heating system (A) of the present invention eliminates these problems.

According to the present invention, the moisture contained in the fuel gas 17 is naturally vaporized by heat of 100° C. to 300° C. and an updraft, and hydrogen by the electrolysis action of tourmaline coated on the combustion catalyst 12, etc. Gas and hydroxyl anions are generated, and a rapid oxidation reaction of hydrogen gas is induced by a noble metal catalyst, generating a large amount of far infrared rays, and food cooking is effectively performed by gentle far infrared heat, and various odors are deodorized and removed by tourmaline and noble metal catalysts .

By heating the combustion catalyst 12 of the present invention, a large amount of far-infrared rays with deep heat penetration are generated at an atmospheric temperature of 100° C. to 300° C., and moisture vaporized from the fuel gas 17 is the electricity of Tourmaline. Hydrogen gas and hydroxide anions generated by decomposition induce a rapid oxidation reaction into water molecules by a noble metal (platinum, etc.) catalyst, thereby generating a large amount of far-infrared heat and anions.

In addition, the hydrogen gas evaporated by the electrolysis of moisture causes an oxidation reaction with oxygen contained in the surrounding air on the surface of the noble metal catalyst coated on the combustion catalyst 12 to generate moisture and heat again, and the heat is the combustion catalyst. Since the mat 12 and the tourmaline are further heated, the evaporation of moisture is greatly promoted and the electrolysis reaction of the tourmaline is also further promoted, so that the amount of far-infrared rays and anions generated is more remarkably improved.

In addition, since the combustion catalyst 12 of the present invention greatly promotes vaporization and has very excellent organic matter decomposition ability, odor is removed or deodorized quickly. That is, the combustion catalyst 12 coated with the noble metal catalyst and tourmaline is activated to quickly release harmful organic substances and unpleasant odors, such as bad odor, fishy smell, fish burn, chemicals, soot, etc. contained in the updraft in a harmless state. decomposed and removed

In addition, since the combustion catalyst 12 is a non-combustion type heating, even if the distance from the heating object 29 is somewhat increased, it is evenly heated by far infrared _rays . There is no stinging in the eyes, and there are advantages such as not having a big problem with use even if ventilation (ventilation through a window or door) is not frequent.

In addition, existing heating devices have problems such as burning or burning when a heating object (food) is close to it, and a significant decrease in heating efficiency when it is a little off, requires a lot of maintenance cost, and generates a large amount of unburned material during initial ignition, which causes eye irritation. Although there were problems such as having to ventilate frequently, these problems are eliminated in the present invention.

When explaining the operating state of the present invention, power is supplied to the plurality of electric heaters 14 by the controller 23 and heated, and when the temperature sensed by the mat temperature sensor 21 reaches the combustion start temperature, the controller ( 23) opens the on/off valve 18 and the fuel gas 17 is supplied to the combustion catalyst 12 through the gas diffusion chamber 16 and the thermal barrier 15, and heat is generated while igniting and burning.

At this time, the temperature value sensed by the mat temperature sensor 21 is continuously input to the control unit C, and the control unit C automatically controls the electric heater 14 so that the temperature is not lower than the catalyst combustion start temperature. .

In addition, the temperature required for heating the necessary heating object 29 is automatically controlled by controlling the gas supply amount by the gas proportional control valve 20 according to the temperature set through the setting unit S of the control unit C.

In the present invention, by installing an electric heater 14, which is a heating and ignition means, on the upper portion of the combustion catalyst 12, it is possible not only to reach the reaction start temperature of the combustion catalyst 12 and to achieve a stable reaction of the combustion catalyst 12, but also , it has the effect of generating infrared rays, negative ions, and heat.

In the present invention, gas and electric energy are saved because the fuel gas 17 and electricity are appropriately controlled by automatic proportional control according to the required temperature, and the intensity of far infrared rays and infrared rays is data by setting the temperature suitable for the characteristics of the heating object 29 . It has the effect of improving the heating quality by automatically controlling it by inputting it.

The present invention has the effect of increasing the durability of the combustion catalyst 12 by rapidly evaporating and removing moisture and impurities that reduce the activity of the combustion catalyst of the combustion catalyst 12 with the heat of the electric heater 14 .

In the present invention, since the alumina-silica mat, which is the material of the combustion catalyst 12, is always heated using the electric heater 14, far-infrared radiant heat is continuously emitted and the heating efficiency is high.

Since the present invention uses electricity and gas complementary to each other, the durability of the electric heater 14 and the combustion catalyst 12 is increased. there is.

The composite heating system (A) of the present invention uses the heat wavelength data according to the temperature of far infrared rays and infrared rays in the case of industrial product manufacturing to perform the process of pre-drying-drying-firing, etc. Data according to the characteristics of the heating object 29 It can be implemented as an automatic system programmed by input.

When the complex heating system (A) of the present invention is applied to household goods, it is an automatic system that is programmed by inputting the characteristics according to the options such as comfortable heating and steaming as data using the heat wavelength according to the temperature of far infrared rays and infrared rays. It can be implemented by applying
