Burning Promotion System using a Brown Gas Shooting Burner Gun}

The present invention relates to a combustion promotion system using a brown gas shooting burner gun, which provides brown gas by supplying brown gas by securing a predetermined space on a center line of a burner using an existing fuel such as oil or LNG. The present invention relates to a combustion promotion system using a brown gas shooting burner gun, which can save fuel by suppressing the emission of pollutants by promoting combustion due to high temperature occurring in the brown gas zone by forming a (brown gas combustion zone).

Until now, industrial boilers have been devised to prevent pollution such as dust collectors at the rear of the combustion chamber to catch pollutants generated by incomplete combustion in the combustion chamber. However, as environmental regulations tightened, the post-treatment approach no longer solved the technical limits.

Therefore, it is desirable to burn well in the combustion chamber so that no pollutants are generated from the beginning. The present invention for solving such a problem is to reduce the emission of pollutants by injecting Brown gas, which is a mixed gas of hydrogen and oxygen into the combustion chamber to promote combustion, which is called a brown gas combustion promoting system.

Brown gas combustion promotion system saves fuel by inducing the incomplete combustion part to complete combustion by injecting brown gas mixed with hydrogen and oxygen into the molecular state of H ₂ and O ₂ into the existing fuel combustion chamber where incomplete combustion is in progress. It is a new combustion technology that can solve the problem.

This combustion technology is made possible by the WE Energy (Water Energy System), which is capable of automatically supplying tap water into brown gas and providing 24-hour, 365-day supply automatically.

WE system means that brown gas plant and combustion device are linked to one system to convert tap water (2H ₂ O) to brown gas (2H ₂ + O ₂ ) in brown gas plant and burn brown gas in brown gas combustion device. It is to get thermal energy.

Therefore, in the present invention, a brown gas plant that supplies tap water to brown gas and supplies it to a combustion device such as a boiler using bunker-C oil is composed of H ₂ and O ₂ by combining brown gas plant as a center of the flame. In order to save fuel and solve environmental problems by inducing incomplete combustion to complete combustion.

20T / h, 50T / h class medium boilers installed in paper mills and chemical plants, or 100T / h, 150T / h large boilers installed in power plants use cheap fuel such as bunker-C oil. In the case of burner guns of such medium and large boilers, a steam supply pipe is generally formed at the center of the burner gun center line, a fuel oil supply pipe is formed at the outer periphery of the steam supply pipe, and an atomizer is formed at the tip of the burner gun so that steam and fuel oil are mixed. After the atomizer is configured to be sprayed from a certain number of injection nozzles formed on the front.

The present invention relates to boiler performance improvement that can reduce fuel costs and solve environmental problems by injecting brown gas while maintaining the fuel oil injection function by atomizing steam.

In other words, the Brown Gas combustion accelerator system can greatly improve performance by modifying only the burner gun without modifying or replacing the combustion chamber of the existing boiler.

The burner gun of the boiler is easy to fix or replace, as it is always removable for repair. Therefore, the present invention is configured to maintain the atomizing steam function while installing the brown gas supply pipe on the center line of the burner gun, and also configured the brown gas nozzle on the center line of the atomizer.

The Brown gas shooting burner gun of the present invention is intended to promote combustion by injecting Brown gas composed of hydrogen and oxygen into a combustion chamber using bunker-C oil or the like.

Prior patents for achieving this purpose include Patent Application No. 10-0397585, "Combustion Promoting Brown Gas Burner" (hereinafter, referred to as a patent).

This cited patent is described in the detailed description of the invention.

The present invention relates to a brown gas burner for promoting combustion, and specifically, a brown gas mixed with compressed air by securing a predetermined space on the outer circumference of an oil nozzle for supplying oil (hereinafter referred to as "BG Mix Air"). The present invention relates to a combustion-promoting brown gas burner capable of supplying fuel to the point where the oil is injected while vortexing to promote combustion, thereby minimizing fuel saving and pollution.

Also in the composition and operation of the invention

"As shown in the figure, the present invention includes a housing (5) in which the oil filling chamber (1) and the chamber (2) and the flange portion (3) are integrally formed at one end of the inner center; An oil spray gun 10 disposed in the oil filling chamber 1; A BG burner gun (15) mounted to the chamber (2); A wind box 20 which promotes combustion by introducing external air; The burner tile 25 is positioned at the distal end of the BG burner gun 15.

As shown in FIGS. 1 and 4, the oil spray gun 10 supplies the oil filter 7 for filtering various foreign substances contained in the oil supplied from the oil supply pipe 6 and the oil to the front side. The filter plug is detachably mounted on the rear side of the oil spray pipe 9 and the housing 5, which are integrally mounted with the spray nozzle 7a and the distal end of the slewer 8 so as to communicate with the oil filling chamber 1; (7b).

The slewer 8 screwed to the distal end of the oil spray pipe 9 is supplied with BG mix air, which will be described later, with the injection of oil, causing vortex as shown in FIG. For the purpose of the present invention, a small hole 8a and a tip portion 8d are formed at the front end of the hollow portion, and three to four braids 8b are arranged at equal intervals on the outer circumference and the spiral portion 8c formed at the rear end portion. It is composed of a structure that is integrally coupled with the oil spray pipe (9) using.

As mentioned above, the cited patent is to secure a certain space on the outer periphery of the oil nozzle for supplying fuel oil, and to inject the brown gas mixed with compressed air, swirling by the swirler, and brown gas to the point where the oil is injected. The present invention relates to a brown gas burner for promoting combustion, by promoting combustion.

In other words, the cited patent creates an oil spray tube on the centerline of the burner gun and forms a Brown Gas spray tube on the outer periphery of the oil spray tube, which swirls by the sprayed oil and swirler sprayed from the center of the burner. Is burned in a mixed state to produce a flame.

However, the present invention, unlike the cited patent, forms a brown gas supply pipe on the center line of the burner gun, forms a steam supply pipe on the outer periphery of the brown gas supply pipe, and forms a fuel oil supply pipe on the outer periphery of the steam supply pipe, which is assembled at the burner tip. Brown gas is ejected from the Brown Gas Injection Nozzle assembled in the center of the Miser and is injected deep into the combustion chamber. Fuel oil is steamed in the atomizing oil nozzle which is installed in a plurality of radially centering the atomizer Brown Gas nozzle. It is configured to be injected with a mixture of fuel oil and fuel.

The present invention is to form a brown gas zone in the center of the flame to promote combustion by using the high temperature of brown gas burning in the brown gas zone.

In order to achieve this purpose, it is preferable to install a brown gas supply pipe on the center line of the burner gun and to configure the brown gas nozzle at the center of the atomizer. It should be configured to be put into the state of not ignited toward the center, that is, the molecular state of H ₂ , O ₂ .

The temperature of the flame in the existing boiler combustion chamber is about 1200 ° C. Since the present invention forms a brown gas zone at the center of the flame to burn brown gas composed of hydrogen and oxygen, the temperature of the flame of the brown gas zone present in the flame is inevitably higher than 1200 ° C.

At this time, the temperature of the flame of Brown Gas John can be estimated to be about 4 times higher than 1200 ° C. If the temperature is higher than 4300 ° K, the temperature at which water molecules are pyrolyzed. If so, brown gas John In can be expected a phenomenon in which heat is created through repeated cycles of thermal decomposition are recombined back to a water molecule (H ₂ O) a H ₂ and O ₂ are generated when the H ₂ and O ₂ to the combustion reaction.

Therefore, the brown gas shooting burner gun of the present invention has a brown gas supply pipe installed on the center line of the burner gun, and a brown gas nozzle is installed at the center of the atomizer so that the brown gas is shot at the center of the flame in the state of H ₂ and O ₂ molecules. It is configured to be.

Brown gas shooting burner gun of the present invention is to shoot the brown gas in the flame of the existing fuel to form a brown gas zone.

In the case of 20T / h to 150T / h class medium and large boilers using bunker-C oil, most of them produce atomizing steam by supplying atomizing steam. Therefore, inside the burner gun, an atomizing steam supply pipe is installed along with the fuel oil supply pipe, and an atomizer is formed at the tip of the burner gun, and a predetermined number of injection holes are formed radially around the atomizer center line.

The injection hole is radially formed at an angle of 40 ° with the atomizer center line, and sprays and diffuses fuel oil into the combustion chamber by atomizing steam. Therefore, it is desirable to configure the Brown gas nozzle while maintaining the spray function as it is.

Therefore, in the present invention, a brown gas nozzle is formed on the atomizer center line without modifying a radial injection hole position to finely inject fuel oil by atomizing steam to shoot brown gas at the center of the flame. will be.

The fuel saving rate by the combustion promotion system of the present invention can relatively increase the fuel saving rate depending on the amount of Brown gas introduced into the existing combustion chamber.

However, in constructing the WE system to increase fuel savings, the capacity of the brown gas plant that supplies brown gas cannot be increased.

Therefore, the desired reduction ratio should be determined to determine the capacity of the Brown Gas Plant.

The present applicant intends to use the Brown gas shooting burner gun according to the present invention as an example of a fuel saving rate, for example of a boiler.

2) Combustion promotion application equipment: heavy oil fuel 20T / h steam boiler

3) New Burner Type: Brown Gas Shooting Burner Gun

2. Combustion promotion effect

1) As mentioned above, when Brown gas was inputted with the combustion promotion system, the flame length increased and the chimney temperature increased.

2) In Brown gas chimney temperature after 2 hours went up from the usual 150 ℃ to 185 ℃ oxygen concentration was increased to 7% has only a 13% CO ₂ emissions are drastically reduced.

3. Achieved 25.6% fuel savings average

As a result of measuring five times every two days, the fuel savings rate was 24.2 ~ 26.9%, confirming the average reduction of 25.6%.

4. In this embodiment, the fuel saving effect of 25.6% was obtained by putting Brown gas 12000 l / h into a 20T / h steam boiler, which was superior to the one originally expected. Therefore, attendees who attended the measurement test at that time shouted with joy, shouting that the combustion revolution took place due to this drive.

5. Identification of Brown Gas Zone (Brown Gas Combustion Zone).

At the time of the measurement, to check the flame state of the Brown Gas Shooting Burner installed at the front of the boiler, the flame was observed by the pipe hole at the rear of the boiler. It is to confirm that. Applicant photo-photographed the scene and published it on the website.

As shown in the above embodiment, even though only 12000 L / h of Brown gas was injected into the 20T / h boiler, the fuel reduction rate of 25.6% is not the combustion revolution by Brown Gas.

Large-scale power plants pay hundreds of billions of dollars of fuel, while medium-sized power plants pay hundreds of billions of fuel. For example, Daejeon Cogeneration Plant equipped with four 150T / h boilers uses 800 billion won of heavy fuel oil annually. By applying the Brown Gas combustion promoting system according to the present invention to this power plant, if the fuel is reduced by 25%, the cost of 20 billion won can be saved annually, and it can be seen how large the fuel saving effect is.

In addition, since the emission of pollutants is reduced by the amount of fuel savings, the present invention solves both environmental problems and energy costs.
