In the method, liquid fuel in kind of of a nepheloid conical liquid fuel column is enclosed by a rotary combustion air stream flowing in tangential into the swirler (1), and additionally gaseous and/or liquid fuel is sputtered into the air stream, as well as with at least a injection nozzle means (8) within the swirler, by which medium caloric or low caloric fuel in axial and/or coaxially is injected.
Description
The present invention relates to a kind of in the burner that has cyclone (Drallerzeuger) combustion of gaseous, liquid and in calorie or the method for low caloric fuel.In addition, the invention still further relates to the burner of implementing said method.
DE19547913A
1Disclose a kind of burner that is used for heating element, at the cyclone 100 that there is shown of this specification, axial liquid fuel is sprayed in the above-mentioned cyclone through the form of fuel nozzle 103 with conical liquid fuel stream.Combustion air flow in the cyclone become tangentially and and aforesaid liquid fuel stream lead at angle between the shell of revolution (Drallschalen) of cyclone, preferably above-mentioned combustion air flow is mixed with gaseous fuel by corresponding ejiction opening 117.Above-mentioned jet 117 is mainly used in and imports this fuel that has the 46MJ/kg high heating value usually of natural gas.Emphasize to some extent in the Germany prospectus of mentioning in the above as for all other structural details of the known burner of use two class A fuel As that also are called as double burner (Dualbrenner).
For example as being learnt from above-mentioned specification, the combustion system that is used for heating element is preferred for the driving of gas turbine.By chance in the subsidiary available natural gas in the gas turbine application field in future and fuel oil also preferentially use as the equipment of double burner fuel calorie or low caloric fuel (Mbtu-resp.LBtu-Bennstoffe) but these traditional fuel is formed with the harmful substances field after burning.These for example from coal or heavy oil gasification are resulting calorie or low caloric fuel (Mbtu-resp.LBtu-Brennstoff) contain a large amount of hydrogen and carbon monoxide, therefore the calorific value of caloric fuel only is about 1/3rd of heating value of natural gas, promptly about 15MJ/kg in.
Caloric fuel mixes mutually in burning gases stream and the gaseous state that is similar to natural gas although can make by tangential entrance in principle, but may form following deficiency: promptly therefore make to have the large volume stream that mixes in the cyclone, thereby make the local very high pressure loss that produces, this will influence the stability of formed gas line constantly.In addition, contain the hydrogen that has the strong reactivity energy in a large number in the middle caloric fuel of mixing, this has very big danger for the tempering of flame in the burner.This incorrect flow will further cause the fuel malcombustion imported, thereby combustion process is obviously worsened, and for example make the NO in the waste gas
xObviously increase.The tempering of flame causes burner overheated the most at last in the burner, and makes some burner member bear great thermic load and near their thermic load critical value.
Although caloric fuel itself is little to the stability influence of swirling eddy in spraying near burner outlet, and avoided the further tempering of flame in the burner, but because mixer is short, caloric fuel and mixing of combustion gases are insufficient in making, thereby combustion process is similar to diffusion, the NO that generation is very many
xThough can reduce NO by middle caloric fuel is suitably fully mixed (hohe Beimischung) with nitrogen or water vapour
xEmission measure, but fuel is so diluted and will cause gas turbine proficiency to reduce.For same consideration, when using low caloric fuel, also to increase input quantity.
Task of the present invention is to provide a kind of combustion of gaseous, liquid and calorie or low caloric fuel, the burner that has cyclone and combustion method of being used for, liquid fuel with conical liquid fuel column form is sprayed into vaporific in the method, the rotary combustion gas stream that the aforesaid liquid fuel column is tangentially flowed in the cyclone surrounds, like this, the burning of the fuel of being mentioned above can making under using the situation of single a kind of fuel obtains following several respects effect:
A) obviously minimizing especially reduces NO to the emission measure of the influential material of environment
xEmission measure with CO;
B) guarantee the flowing relation set up in the cyclone, especially can avoid or eliminate the hidden danger that flame refluxes in the burner;
C) guarantee flame stabilization;
D), increase the acquisition of energy by means of full combustion of fuel; And
E) by in burner, spraying into the efficient of middle calorie of non-dilution fuel raising gas turbine.
The theme of dependent claims is preferred other features by the present invention's design.Theme of the present invention is: gaseous fuel (as natural gas), liquid fuel (as oil) and in or low caloric fuel (so-called Mbtu-or LBtu-Brennstoffe) burning jointly in the burner of band cyclone, wherein in or low caloric fuel sprayed in burner or the cyclone vertically and/or coaxially.Be preferably near liquid fuel jet part above-mentioned fuel is sprayed into the inside of cyclone, aforesaid liquid fuel cyclone inside at each burner under the state of spraying into forms the conical liquid fuel column gradually.Can guarantee in this way to spray into the additional tiny fog-like liquid fuel of cyclone inside can be very fully with in or low caloric fuel mix.
Will in or low caloric fuel spray into cyclone inside vertically or coaxially and can cause the burner flow field obviously to change, can strengthen above-mentioned axial flow part by caloric fuel in additional the spraying into, and rotating part reduces in the same way almost.As from above-cited Germany prospectus DE19547913A1 especially from the capable described example of the 4th hurdle 55-66 available known manner reduce rotating part, thereby make so-called backflow bubble (R ü ckstr mblase) instability, so that make the recirculating zone flame stabilization.
Different with the top double burner principle of mentioning is can normally the backflow bubble that is produced in the recirculating zone be blown off owing to having increased the axial flow part, therefore can eliminate the hidden danger of tempering significantly.
As this paper begin to be mentioned, central or low caloric fuel contains a large amount of hydrogen and has very by force when reactive, these fuel are still guaranteed the necessary flame holding of burning, will form the retention flame and can not form the recirculating zone effectively this moment.
Also will in or low caloric fuel send into liquid fuel entrance zone with sailing against the current so that well mix with fuel that has sprayed into and the burning gases that spray in the cyclone.In this manner, because the mixing segment length of premixed combustion has more satisfactory NO
xThe emission value can obtain above-mentioned emission value when natural gas is carried out premixed combustion.
In order to reduce corresponding emission value nitrogen or water vapour are mixed.The special benefits of doing like this is to have avoided the efficient of the whole gas turbine that causes because of dilution to reduce.
Implementing the burner of the inventive method regards as the improvement at the described double burner of above-mentioned Germany prospectus DE19547913A1, according to the present invention, the 3rd fuel system of also additional general or low caloric fuel input cyclone on the fuel system that is used for natural gas and liquid fuel.Be preferably near the entrance zone, center, the liquid fuel by spraying into cyclone inside, the shell of revolution by cyclone, by entrance will in or low caloric fuel spray into the inside of cyclone.In or the input of low caloric fuel and liquid fuel input carry out vertically and/or coaxially, they are respectively with the cyclone axial symmetry.
