The way bassanova combustion

 

The invention relates to a power system, namely the technology bassanova combustion of the fuel. Besagno combustion is carried out by a separate supply to the burner fuel with air and superheated water vapor. Upon receipt Sanogo flame this flame is served superheated steam and the heat of the burner. After warming up air supply to the burner overlap fully or partially superheated steam gasification produces carbon (soot) in the synthesis gas. The resulting synthesis gas derived from a burner for subsequent combustion. The invention allows for high efficiency of fuel burning without soot. 1 Il.

The invention relates to a power system, in particular to technology bassanova combustion of fuel and raw materials.

The known method bassanova combustion with steam injectors, consisting in the supply of fuel by gravity, and vapor under pressure. The fuel and steam are mixed in the nozzle, and the mixture of fuel and steam is burned in a flare. Fuels, in particular oil before it enters the nozzle is heated to a temperature of 85-115With the p>

and the higher the steam temperature, the higher the degree of dissociation.

The carbon in the fuel combines with oxygen water, the fuel is gasified, turning into the hot gases carbon monoxide and hydrogen With+H2O=CO+H2that burn in the oxygen of the atmospheric air, turning into carbon dioxide and water.

The effect of the dissociation of water can improve the combustion efficiency due to the additional oxygen so that steam nozzles create Bassigny torch [1].

In this way steam having a higher temperature, is mixed with the relatively cold fuel. The temperature of the steam decreases, and went to the process of dissociation, it is necessary to raise the temperature of the vapor, which requires you to spend part of the chemical heat release and hence the flame temperature is reduced.

The lower the steam temperature, the lower the degree of dissociation, and hence the low combustion efficiency, which in this case is determined kolichestvennaia is the fuel oil and water under pressure are fed into the emulsifier. The resulting emulsion is pumped to the nozzle, where the pressure is simultaneously supplied air. The mixture of emulsion (water - oil) and air is burned in a flare. Water droplets suspended in the oil, have a temperature exceeding the boiling point, and during the ejection of the jet occurs secondary atomization.

Formed by thermal dissociation of water, oxygen reacts with carbon and oxidize it to carbon monoxide [2].

However, despite the fact that, compared with the above method of burning, spraying fuel more efficiently, but it pairs reduces its temperature, mixed with fuel, and therefore the degree of dissociation of water is reduced and as a consequence worse fuel burn efficiency.

Closest to the claimed method bassanova fuel combustion is the combustion method, which consists in simultaneously feeding to the burner fuel, air and superheated water vapor.

Fuel, air and superheated steam are mixed together in the combustion device, while the water required for steam, served in a certain ratio to the air flow. The resulting steam is mixed with vosklicanija condensation of steam prior to its contact with the fuel [3].

However, in this method of burning fuel, as well as in the previous methods, mixing superheated steam and fuel, which reduces the temperature of the vapor, and thus decreases the degree of dissociation, and hence deteriorates the efficiency of combustion of fuel.

The basis of the invention is to provide a method of burning fuel, providing high efficiency of its combustion without the formation of soot.

The problem is solved in that way bassanova fuel combustion, including the supply of water steam, fuel and air to the burner, according to the invention superheated steam and the fuel and air are fed to the burner separately, after receiving Sanogo flame jet of superheated water vapor according to the invention serves in canoe flame, the device warms up, after heating according to the invention overlaps the air supply completely or partially, the water vapor produces the gasification of carbon in the synthesis gas and the resulting synthesis gas is removed from the burner for subsequent combustion.

Due to the fact that in the present method bassanova burning fuel supply of water steam and fuel with air sudeste air, and superheated water vapor permeates not relatively cold fuel, as a prototype, and hot gases Sanogo flame, allowing the temperature of the steam rises, it begins a process of dissociation of water, which adds to the flame of oxygen.

The steam flow drags canoe flame, and it podsushivaet air from vozduhopodgo, which increases the flame temperature and the temperature of the vapor.

After warming up of the burner, in which the steam temperature reaches such a value that enough oxygen for oxidation of carbon (soot), vozduhootvod overlap fully or partially, as the air begins to interfere with the process of gasification of carbon. He, first, cools the flame, and secondly, contains 79% of ballast gases that prevent the combination of carbon with oxygen.

Obtained in the burner unit, the synthesis gas has a sufficiently high temperatures to effectively burn in the air.

The burner may be of various constructions, it depends on the type of combustible materials, combustion gases, kerosene and diesel fuel can be made in the devices of this design, which is specified in the description as an example.

Burning otrb the UDA instead of air must be superheated steam.

The drawing schematically shows one of the designs of the burner for bassanova combustion.

The device includes a housing 1, made in the form of a glass, a steam nozzle 2 that is mounted in the bottom of the housing 1, vozduhoprovodyaschih hole 3 made in the body 1, the fuel line 4, mounted in the lower part of the housing 1, the steam pipe 5, connected with a steam nozzle 2, the ignition zone 6, which is fed fuel.

The way bassanova combustion is carried out as follows. The fuel line 4 is supplied diesel fuel in the ignition zone 6, where it is ignited and burns Sanam flame in the oxygen of the air, which is sucked through the holes 3.

Continue to serve the water vapor pressure of 2 kg/cm2and a temperature of 150With that expires from the nozzle 2 up in the form of a stream that runs through canoe flame, and drags with it the flame. Educated stream starts stronger to drain the air through the holes 3 and the flame temperature increases.

After heating device until the red glow of the housing 1, the holes 3 block (not shown) and the burner continues to operate without access of air. The air is blocked for two reasons the e interfere with the oxidation process of carbon.

When the steam pressure is below 2 kg/cm2and the temperature is below 120With the observed unstable combustion, the flame is reduced and smokes because of the lack of oxygen, but is slightly open hole 3, a stable combustion is restored, the torch is bright red in color and black carbon are not visually observed.

By increasing the steam pressure and temperature, a decrease in the length of the torch and lighter glow, noise also increases.

When the vapor pressure of 7 to 10 kg/cm2and the steam temperature above 300From there the blue glow of the flame, which indicates efficient combustion of carbon monoxide. Carbon monoxide gives the blue glow of the flame.

Thus, in the present invention the fuel is fed to the burner separately, in any way, burning at atmospheric pressure in oxygen. Forced air supply is not required here, since the steam flow produces a suction of air through vozduhootvod (this is necessary in the initial stage of the process).

The steam is also fed separately through steam nozzle under pressure. Further mixing of the superheated steam is not with the relatively cold fuel the flame temperature, but from increasing the temperature of the flame at the expense of air leaks.

The temperature of the steam increases, the degree of dissociation (i.e., added oxygen), which leads to increased oxidative processes.

In the burner device is gasification of carbon (soot) water vapor, providing high efficiency of fuel burning without soot.

The proposed method bassanova combustion can be used in burners for various purposes, as heating devices, dryers and so on, as well as devices for waste disposal, with the ability to burn Sanam flame.

It should be noted that for this strategy to work, requirements for clean fuel are extremely low, so it can burn kerosene, diesel fuel, and other, recent technological use (for example, sink details).
