Description

Device for increasing combustion efficiency of gas equipment using steam {ENHANCEMENT DEVICE OF COMBUSTION EFFICIENCY FOR GAS APPLIANCE USING STEAM}

The present invention relates to an apparatus for increasing the combustion efficiency of gas equipment using water vapor, and to increase the thermal power by injecting (ejecting) water vapor into the flame of a gas machine such as a gas stove or a gas boiler. By improving the efficiency of combustion, saving fuel, and nearing the complete combustion, it is possible to prevent indoor pollution and air pollution and lead the green growth industry.

In general, gas appliances such as gas stoves and gas boilers use fuels such as LNG and LPG. In the case of cooking stoves, not only the soup overflows or the food splashes, but also the surrounding area becomes dirty.In particular, the burner gets stuck or burns (flameholes), so that the heat efficiency decreases or soot or unburned gas generated by incomplete combustion. Not only is indoor air contaminated by the back, but also burns a large amount of oxygen in the indoor air when it is burned, so there is a problem in that the door must be frequently ventilated.

For example, 15-29% of LNG and 25-30% of LPG are incompletely burned in the gas fuel used in the kitchen, and carbon monoxide, formaldehyde, carbon dioxide, sulfur dioxide, etc. are emitted. If you use a gas stove for 1 hour based on a 30 pyeong apartment after ignition after drinking gas, the concentration of carbon monoxide in the kitchen will be 0.1%. Especially, carbon monoxide has a strength of 150 to 300 times stronger to coagulate hemoglobin in the blood. Because of this, it is known to reduce blood circulation and function of tissue cells in the body.

According to the present invention, when the gas appliance is ignited and a flame (5) is generated by the burner (3), combustion is started. The water vapor 5 generated as the water 16 is heated by applying power to the electric heater 17 and the blower 12 is supplied to the venturi tube 2 through the outlet 11 and is supplied to the blower tube 12. The outside air is blown (supplied) to the venturi pipe (2) by the air vapor (5) mixed with air is supplied through the supply pipe (10) → branch pipe (9) → steam supply pipe (4) → water vapor injection port (4a) The water vapor 5a, which is injected into the flame 5, is mixed with air and thermally decomposed into hydrogen and oxygen by being instantaneously heated and pyrolyzed while being directly exposed to the flame 5 at several hundred degrees Celsius. ) Increases the size of the flame (8a) and the temperature rises, greatly improving the combustion efficiency, combustion close to complete combustion The.

Reference numeral 31 is a fuel gas supply pipe, 32 is an air mixing pipe, 34 is a burner cap, 39 is an ignition port, 40 is a support member, and 41 is a cooking vessel. to be.

On the other hand, when the user stops the gas appliance or the flame (8) (8a) is extinguished due to an abnormality, it is detected by the combustion detection sensor (P), the controller (7) 7a is the flame (8) of the gas appliance It is judged that 8a is turned off (fired) to stop all operations including the blower 12, so that the injection of the air-mixed water vapors 5a and 5d is prevented.

In the present invention, the degree of injection (injection amount or injection pressure) of the air-mixed steam (5a) (5d) is controlled by the variable displacement blower 12, the pumping capacity of the blower 12 is the controller (7) (7a) It is set in advance by the setting unit S of.

In the present invention, the water level of the heating chamber 14 or the water tank 14a is maintained at a constant water level by the water supply control means 22. That is, when the water level is lowered as the water 16 of the heating chamber 14 or the water tank 14a is consumed by the heating or ultrasonic vibration, the floating body 24 is lowered and installed inside the floating body 24 ( Since the built-in permanent magnet 25 is lowered along the floating body 24, when the second hall element 30 senses and inputs it to the controller C, the controllers 7 and 7a replenish the lowered water level. In order to operate the water supply pump 20 to supply water from the water supply source 21 to the heating chamber 14 or the water tank 14a through the water supply pipe 19, the water of the heating chamber 14 or the water tank 14a ( 16) The water level will rise.

As the level of the heating chamber 14 or the water tank 14a rises, the floating body 24 rises, and the permanent magnet 25 installed in the floating body 24 is installed along the floating body 24. Since the first hall element 29 located at the upper side detects this and inputs it to the controller C, the controller 7 or 7a determines that the water 16 has been replenished with a sufficient water level. The water supply of the water supply source 21 is cut off by stopping 20, and the water level 16 of the heating chamber 14 or the water tank 14a is maintained in a certain range (elevation section) by repeating this process.

In the present invention, in the combustion efficiency increasing apparatus 1 of the electrothermal heater heating method, since the heating water temperature is detected by the temperature sensor 18 installed in the heating chamber 14, the heating state of the water 16 is heated or not. The controller 7 can determine.

The combustion efficiency increasing apparatus 1a of the ultrasonic vibration method is water vapor in the state where the water in the vibrating chamber 35 is atomized to a normal temperature around 25 ° C at or around 25 ° C similar to or similar to the water temperature of the water tank 14a by ultrasonic vibration. 5) It is rapidly heated and rapidly decomposed into hydrogen and oxygen as it is injected into 5), and complete combustion is induced through micronization and activation of fuel gas, and the fire power is greatly increased as the flame (8a) increases. Fuel gas is saved.

The steam 5 generated by the combustion efficiency increasing apparatus 1 of the electrothermal heater heating method is saturated steam or superheated steam generated by boiling water 16 with the electrothermal heater 17 and thus exceeds 100 ° C. The temperature is maintained, and as described above, it is instantaneously heated while being injected into the flame (5) to thermally decompose into oxygen and hydrogen, and the complete combustion is induced through the differentiation and activation of the fuel gas and the flame As 8a becomes larger, the thermal power is greatly increased, and fuel gas is saved.

Thermal Decomposition and Combustion Theory, confirmed by the French chemist Antoine-Laurent Lavoisier (1743-1794), heats and heats a metal tube at high temperature to heat the metal tube. Passing generates hydrogen. For example, the water molecules are activated at a temperature of about 500 ° C., and thus weak bonds are broken down into oxygen gas and hydrogen gas (for example, 2H 2 O → O 2 + 2H 2 ^), and the oxygen gas and hydrogen gas are flames in the present invention. While acting on chemical synergy, the fire power of the flame is greatly increased.

That is, in the present invention, the water molecules in the state of water vapor (5a) (5d) is exposed to the flame (8), thermal decomposition and activation by the instantaneous high heat, weak molecular bonds are broken down into oxygen and hydrogen, and thermal power by chemical synergy It is stronger than this. The steam (5a) (5d) is injected into the flame (5) is exposed to the high heat of the flame (8) is an endothermic reaction (entropy) more than the internal energy (enthalpy) due to the endothermic reaction (pyrolysis) will occur well.

In the present invention, the surface of the water vapor injection port 4a may be coated with a material in which a large amount of far infrared rays and anions are generated by heat (combustion heat) such as ceramics. For example, when coating a catalyst material mixed with alumina oxide (Al ₂ O ₃ ), transition metals (Cr, Co, Ni, Mn, Fe, etc.) and precious metals (pt, pd, Rh, etc.), LNG, LPG It is possible to completely oxidize and burn the fuel gas.

When the ceramic material or the like is coated on the surface of the water vapor injection port 4a as described above in the present invention, a large amount of far infrared rays and anions are generated, the deodorizing effect is further improved, the surrounding harmful electromagnetic waves are neutralized, and the combustion efficiency is further improved.

The present invention is close to the complete combustion, there is no occurrence of nax (NO _X ) or the like, there is no need to ventilate frequently, and since the water vapor (5a) (5d) is pyrolyzed to generate anion anion in addition to hydrogen and oxygen 5 ~ 15㎛ Far infrared rays of are emitted in a greater amount, and the hydroxyl anions generate in the combustion process or neutralize harmful electromagnetic waves in the surroundings.

In the present invention, the steam (5a) (5d) is pyrolyzed as shown in the following formula (1),

^{_{H 2 O → H + + OH}} - ----------------------------------------- ------- Formula (1)

Herein, the separated hydrogen ions (H +) are attracted to the cathode as shown in Equation (2) below, are combined with electrons emitted from the cathode, and neutralized to form hydrogen gas (H ₂ ).

_{^{OH - + H 2 O → H}} 3 O 2 - (hydroxyl ion) ------------------------------ formula (2)

That is, hydroxyl ions (OH-) combine with the surrounding water molecules to form a surface active material called a hydroxyl anion, which is an anion.

In the case of the catalyst material is activated by a catalytic reaction by the action of the combustion gas and water (moisture), various organic substances or unpleasant odors contained in the combustion gas are quickly decomposed and removed in a harmless state.

In the present invention, since the oxygen generated by the pyrolysis action and external air pumped through the blower 12 is added and burned, indoor oxygen consumption is reduced, and indoor air is pleasant by anion and far-infrared action, and almost no harmful gas is generated. Therefore, thermal efficiency is high, and economical and instantaneous high temperature can be easily obtained.

The far-infrared rays penetrate to the depth of the superficial layer (3 ~ 4cm) to promote cell activity, promote blood circulation in the human body, maintain the body temperature at the proper body temperature, promote the excretion and odor of various waste products of the human body It neutralizes, reduces excess salts that cause adult diseases, excretes subcutaneous fat, regenerates into glossy young skin, promotes the growth of the human body, and increases the analgesic and epithelial formation of thermal burns. Because of the short healing period and no scars are known to work.

Therefore, the far-infrared rays and negative ions act on a person who approaches or cooks near the stove, which affects the human body.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, It is self-evident to those of ordinary skill.
