Description

Boiler using Brown gas

The present invention relates to a boiler apparatus using brown gas, and more particularly, to a boiler apparatus using combustion heat of brown gas as a heat source.

The boiler according to the prior art is a device arranged to generate water or steam having a predetermined pressure and temperature by burning fuel to heat water, and supplying the same to a required place.

FIG. 1 illustrates a basic structure of a boiler, in which a fuel is combusted in a combustion chamber, and heat of water in the main body is used to obtain steam by using heat energy obtained therefrom, and a turbine or the like is driven by a superheated steam obtained by overheating it. .

At this time, as a heat source of the boiler, fossil fuels such as coal, petroleum, and natural gas are usually used.

In this case, a large amount of combustion air must be supplied to a normal combustion chamber for burning fossil fuel, and the smoke generated at the time of combustion is discharged to the outside through the chimney as much as the combustion air supplied to the combustion chamber.

At this time, the energy lost to the chimney without being used is generally about 60% of the total supply energy, and fossil fuels generate carbon dioxide as a combustion product, and soot, ash, and other impurities are generated as byproducts Cause.

Mankind has made constant efforts to recover and use this lost energy, but there is no better way than to blow it.

In other words, the combustion method that needs to blow air to burn fossil fuel has reached the technical limit in the method of increasing the combustion efficiency, there is no further development. In the technology of fueling water with alternative energy, it was only known that the electrolysis of water produced hydrogen fuel, and the fuel was not commercialized.

Therefore, studies on alternative energy sources such as hydrogen gas obtained by electrolysis of water are actively underway, and Brown gas is also considered as one of such alternative energy sources.

In other words, although anyone could electrolyze, the water is electrolyzed to prevent the use of fuels such as heaters, boilers, furnaces, and incinerators.

Despite 170 years of electrolysis history, water cannot be used as a fuel because it has no knowledge of the characteristics of brown gas, the fuel of water electrolysis. Brown gas has unique characteristics such as complete pollution-free characteristics, complete combustion characteristics, improvisation characteristics, thermonuclear reaction characteristics, as well as clean energy without explosion risk like propane gas, and its value as an alternative energy is infinite.

However, in order to use this as a heat source of a boiler, a structural design that can appropriately utilize the unique characteristics of Brown gas is required.

It is an object of the present invention to provide a boiler apparatus having a structure suitable for using the above brown gas.

1 is a schematic view for explaining the structure of a conventional boiler.

It is characterized by including.

In addition, the heating bath is preferably characterized in that the rotating member is provided at a predetermined position inside the heating bath in order to equalize the upper temperature of the water heated by the combustion nozzle and the lower temperature of the unheated water.

In addition, the rotating member is preferably characterized in that the temperature sensing unit for controlling the operation of the rotating member by measuring the temperature of the water heated in the heating bath.

In addition, the boiler is preferably characterized in that the water supply tank for temporarily storing the water in order to send the water heated in the heating water tank is provided on the outside of the heating water tank.

Before describing the present invention, the characteristics of the brown gas used in the present invention and the brown gas generator will be described.

Here, Brown gas is a gas obtained by electrolysis of water and is a mixed gas having a content ratio of hydrogen and oxygen exactly 2: 1. Usually, when water is electrolyzed, hydrogen is obtained at the cathode and oxygen is obtained at the anode. Brown gas is collected at once without collecting these gases separately.

First of all, the characteristics of brown gas are as follows: 1) Completely pollution-free characteristics: Brown gas is produced in water and reduced to steam after combustion, so it does not cause pollutants.

2) Complete combustion characteristics: Brown gas is a mixed gas mixed with a chemical equivalence ratio of hydrogen to oxygen 1, and thus contains the appropriate oxygen for complete combustion.

3) IMPLOSION Characteristics: Brown gas generator produces about 1860 liters of brown gas with 1 liter of water. Conversely, burning 1860 liters of Brown's gas in a sealed pressure vessel by sparking produces again one liter of water and the rest of the volume is vacuumed. This is a concept that is completely different from the explosion.波: implosion). When burning Brown gas, the flame is a continuous process of impursion. Therefore, the flame does not burst and goes straight, forming a pinpoint flame, and the length of the flame reaches 400 mm.

4) Thermonuclear Reaction Characteristics: Brown gas is gas that dissociates water into atomic hydrogen and oxygen rather than molecular state and keeps it mixed without separating hydrogen and oxygen. In addition, the flame when burning Brown gas has a unique characteristic of reacting hydrogen and oxygen in atomic and molecular states. Hydrogen atoms and oxygen atoms penetrate into the nucleus of the material to be heated. Therefore, the material heated by thermonuclear reaction by hydrogen and oxygen is heated by the flame much hotter than the flame when the gas burns alone in the air. Brown gas can dissolve aluminum well at 700 ℃, while tungsten vaporizes the target material with 6000 ℃ of heat. Brown gas, which has different thermonuclear reaction characteristics depending on the material to be heated, can be welded by melting brick and iron as it is.

5) Self-heating phenomenon by infrared ray: The absorption rate of infrared ray is the highest absorption rate in the near infrared wavelength range of 3㎛ and also the high absorption rate in the far infrared 6 ~ 11㎛. The water molecule absorbs almost 100% of infrared rays when it hits infrared rays in the wavelength range of 3㎛. At this time, water molecules are excited and radiate higher energy as heat as molecules collide with each other.
