The specific embodiment
During gas turbine 18 work, air 10 is sucked compressor 14, and herein air is carried out high compression.Compressed air 10 is fed to burner 1 as combustion air 10 subsequently, and mixes with fuel gas with low heat value SG.Combustion gas-the air mixture of Xing Chenging burns in combustion space 17 thus, thereby produces the very high burning gases of temperature.High-temperature combustion gas is fed to turbine 18, and decompression acting herein, thereby drives the armature spindle 15 and the generator shaft 22 of compressor side, makes it enter rotation status.The electric power of Chan Shenging exports a power distribution network to by generator 19 by this method.Be discharged from the outflow side of waste gas form through part cooling and post-decompression burning gases from turbine 18.There is harmful substance in this part waste gas 20, particularly the nitrogen oxide that forms under the hot environment in combustion space 17.
The reason that causes nitrogen oxide emission to raise is that also the mixture of being made up of combustion gas and air mixes evenly inadequately, and perhaps time or spatial variations have taken place its mixing flow field.This can cause fuel gas with low heat value SG with combustion air 10 bad mixing the, the consequently remarkable rising of nitrogen oxide production rate in the combustion process to take place usually.
To this, solution of the present invention can significantly be improved synthesis gas SG and combustion air 10 mixing quality at the flame front place, thereby only produce a small amount of harmful substance when guaranteeing the work of burner 1 usefulness synthesis gas, wherein can avoid occurring temperature peak, thereby make the formation of nitrogen oxides relevant be lower than traditional synthesis gas burner with heat.
By Fig. 2 design of the present invention is described below, Fig. 2 shows is of the present invention one to be used for the burner 1 of lower heat of combustion combustion gas SG.It is the rotational symmetry structure of benchmark that burner 1 roughly is with axis 12.One is surrounded by an annular air transfer passage 7 with same center of circle along igniter 9 axis 12 orientations, that have a fuel transport passageway 8.Fuel transport passageway 8 is designed for the conveying exotic fuels, for example natural gas or fuel oil.
By means of igniter 9, burner 1 also can be used as the diffusion flame burner that uses exotic fuels.Scheme as an alternative, burner 1 also can be used as premix burner; That is to say, earlier exotic fuels are mixed with combustion air 10, and then use it for burning.In the case, igniter 9 is used to keep a pilot flame, and when possible change took place the ratio of fuel and air, described pilot flame also can make burning keep stable in the premix burner course of work.
When burner 1 used synthesis gas to carry out work, low heat value synthesis gas SG always earlier was delivered to mixed zone 27 with combustion air 10 by following current, and after fully mixing herein, did not do to burn in the combustion zone of detailed icon in a figure.
As indicated above, because the volume flow of fuel gas with low heat value SG is very big and how much of the mixed zone 27 that causes thus expand, be difficult to up to now guarantee that relevant gas reaches even mixing on time and space, to reduce the nitrogen oxide that generates in the burning.Can realize mixing especially uniformly between combustion air 10 and the combustion gas SG by burner 1 of the present invention.This point realizes that by the eddy current generating device 4 in the air duct promptly, directly 27 upstream is converted into an eddy current to combustion air 10 in the mixed zone.This depends on the raising of the churning in the microcosmic scope,, must avoid occurring having the maelstrom track of obvious wake zone that is, the components of flow pointed to of adverse current especially, otherwise will have the danger that occurs flash back phenomenon in the burner 1.This requirement has direct influence to the structural design of eddy current generating device 4.Fig. 3 shows a feasible and particularly advantageous design of eddy current generating device 4 with plan view forms.Wherein, eddy current generating device 4 needn't occupy the whole channel height of air duct 2.
Can realize that by eddy current generating device 4 shown in Figure 3 combustion air 10 mixes on room and time especially uniformly with synthesis gas SG.Meanwhile, the pressure loss that eddy current generating device 4 causes is very little, thereby can produce harmful effect to the efficient of synthetic air burner 1 hardly.
Below the vertical view of eddy current generating device 4 shown in Figure 3 and Fig. 4 are elaborated with the side view of the eddy current generating device 4 shown in the same reference numeral:
A large amount of braces 54 limit collar 52 in that is evenly distributed on the limit collar circumference extends to limit collar 53 outside.On the symmetry axis 59 that is centered close to interior limit collar 52 of outer limit collar 53, brace 54 is perpendicular to interior limit collar 52.Joint face 56 is rendered as the side surface of a truncated cone between interior limit collar 52 and the outer limit collar 53.Be furnished with on each brace 54 that the described truncated cone of a plurality of sensings is inside, trapezoidal, the deflection element 51 on plane.The broadside 51a of each deflection element 51 all links to each other with brace 54.The deflection element is that concentric circles 55a, 55b, the 55c in the center of circle equidistantly arranges each other along three with symmetry axis 59.Deflection element 51 is towards a normal slope of joint face 56, and wherein, those deflection elements 51 of arranging on same round 55a, 55b or 55c are to tilt in the same way, then is reversed dip between two adjacent round 55a, 55b, deflection element 51 on the 55c.
When combustion air 10 vertically to enter described truncated cone inside towards joint face 56, when flowing through eddy current generating device 4, can form eddy current 57 on the narrow limit 51b of deflection element 51.Combustion air 10 has formed the miniature eddy current that always continues to mixed zone 27 therefrom.The fuel gas with low heat value SG of certain volume flow with enter mixed zone 27 respectively from the eddy current shape combustion air 10 of air duct 2 owing to exist described miniature eddy current to realize both mixing fully and uniformly in the combustion air 10.In addition, the inclination of deflection element 51 also can make combustion air 10 also have secondary stream 58 except that main flow, owing to eddy current is realized the local good well-mixed while, described secondary stream helps in the entire cross section scope of mixed zone 27 (referring to Fig. 2) to realize the homogenising of combustion gas-air mixture in combustion air and combustion gas.4 of eddy current generating devices flow to the air that enters air duct 2 and exert an influence under the synthesis gas mode of operation, and the effect of this design is that the pressure loss that eddy current causes is especially little.
Therefore, burner 1 of the present invention is specially adapted to power station plant 24, by integrated gasification installation fossil fuel is gasificated into synthesis gas SG (for example coal gas), and wherein, burner 1 is arranged in the combustion chamber 16 of a gas-turbine installation 25.
