Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is an improvement of a burner type combustion apparatus for improving the thermal power or combustion efficiency (fuel consumption) of LPG and other gaseous fuels (meaning all gas fuels that are made gaseous immediately before combustion). Regarding the method.

[0002]

2. Description of the Related Art A burner type combustion apparatus is of a premix type in which gaseous fuel and air are mixed in advance by a burner tube and ejected from the tip thereof to ignite and burn. There is a diffusion type in which fuel and air are introduced into a combustion chamber and mixed and burned. These have already accumulated a great deal of research and usage records over a long period of time,
It was said that there is almost no room for improvement in terms of fuel efficiency, thermal power, etc. unless a new material that is groundbreaking appears.

The present invention intentionally breaks this prejudice and, assuming the possibility of introducing free energy, which has recently been attracting attention in some cases, puts a significant cost burden on the conventional burner type combustion apparatus. The challenge is to improve to a more energy-saving and power-up type without making a call.

[0004]

As a result of various experiments and measurements conducted in order to solve the above-mentioned problems, as a result, gaseous fuel (1) (in the present invention, gasified immediately before combustion and oxygen or air By providing a shutter (3) having a through hole (2) with an opening ratio of 15 to 85%, preferably 25 to 50% in the passage or outlet (including all cases such as mixed ones), it is clear. We were able to recognize a reduction in fuel consumption and an increase in thermal power.

The main items of the experimental data are shown below. (1). The time and use required to heat 4 liters of water from 20 ° C to 70 ° C when the shutter (3) is attached to the outlet of the divergent nozzle (4) of the LPG (propane gas) cylinder as shown in Fig. 1. Regarding the amount of fuel, A: When a square with an aperture ratio of 50% is drilled, time: 3 minutes 02 seconds Fuel used: 4.42 l B: When a hexagonal star with an aperture ratio of 40% is drilled, time: ...... 3 minutes 08 seconds Fuel used ...... 4.45 l C; When a circle with an aperture ratio of 30% is drilled, time ...... 3 minutes 12 seconds Fuel used ...... 4.48 l D; If not attached, time: 3 minutes 16 seconds Fuel used: 4.60 liters

(2). In addition, when the shutter (3) is attached to the outlet of the burner tube (5) as shown in FIG.
The time required to heat 1 liter of water from 25 ° C to 70 ° C and the amount of fuel used are as follows: A; When a hexagonal star with an aperture ratio of 45% is drilled, time: 4 minutes 37 seconds Fuel used: … 1.1l B; When a + type with an opening ratio of 40% is drilled, time: 4 minutes and 37 seconds Fuel used: 1.1 l C; When an equilateral triangle with an opening ratio of 50% is drilled, time: ...... 4 minutes 39 seconds Fuel used …… 1.1l D; When a circle with an aperture ratio of 25% is drilled, time ………… 4 minutes 40 seconds Fuel used …… 1.1l E; aperture ratio 30% -When the shape is punched, time: 4 minutes 42 seconds Fuel used: 1.1 l
(Yellow flame is mixed) F: When a gear with 70% aperture ratio is drilled, time: 4 minutes and 43 seconds Fuel used: 1.1 l G; When a regular hexagon with 70% aperture ratio is drilled, Time: 4 minutes 47 seconds Fuel used: 1.1 l H; When a circle with an opening ratio of 70% was drilled, time: 4 minutes 51 seconds Fuel used: 1.1 l I; If not, time: 5 minutes 24 seconds 1.2 liter of fuel used

According to various other experiments, the aperture ratio was 85.
It was also found that when the content exceeds 15%, the effect peculiar to the present invention becomes unclear, and when it is less than 15%, the momentum of the flame is weakened and the combustion tends to be incomplete.

Further, the through-hole pattern generally has a characteristic that it is surrounded by a right-angled or acute-angled contour, such as a triangle, a quadrangle, a star, a + or Y-shape, a radial shape, a gear shape, and a petal shape. In some cases, it was also found that the effect was more remarkable than that of a circular or obtuse angle figure with the same aperture ratio.

[0009]

In the present invention, the reason why the burning power and the combustion efficiency of the burner flame are improved can be explained completely based on the conventional scientific system, or the problem of free energy which has been recently raised. Whether or not the introduction should be assumed has not been concluded yet, and it is not the main purpose of the present invention to clarify this. In other words, the structure in which a passage was provided at the same time as a shutter-like obstacle in the passage or outlet for gaseous fuel causes disturbance in the flow of fuel gas, which has a positive effect on the complete oxidation reaction. It is believed that However, although the energy of "ki" and the pyramid power are unexplainable in modern science, the existence itself is indisputably confirmed, and the input that clearly violates the "law of conservation of energy" It has been reported that a power generator with a higher output and the fact that an electrolysis product above the theoretical value was obtained by passing a direct current in a pulsed manner like the electrolysis method recently patented overseas is reported. However, it is also necessary to take into consideration the concept of free energy, which is currently the subject of debate, and above all, the attitude of not easily erasing the facts seems important.

[0010]

Example 1 In a diffusion burner in which heavy oil is preheated, sprayed at high pressure, rapidly mixed with air and burned, a stationary shutter having a square opening with a 50% opening ratio at the tip of a fuel spray nozzle is used. Attach the metal or ceramic tubular body in the passage.

[0011]

[Example 2] In a premixed burner for LPG, welding, fixing, or integral molding is performed so that the tip of the burner tube is filled with a metal plate obtained by hollowing out an equilateral triangle having an opening ratio of 45%.

[0012]

[Embodiment 3] In a main burner for a domestic or commercial gas stove, a water heater, etc., which uses LPG, LNG, or city gas as a fuel, the opening ratio of each ejection port is 70.
Set the batch type shutters so that they are aligned with each other so as to be covered by the star-shaped holes.

[0013]

EFFECTS OF THE INVENTION According to the present invention, only by adding a very low cost and durable element without significantly complicating or upsizing the structure, it is possible to increase the thermal power and at the same time reduce the fuel consumption, thereby saving energy and efficiency. There is an effect that leads to improvement.
