Description
Technical field
The present invention relates to utilize the premix burner of gas and/or liquid fuel operation combustion chamber, it has the vortex generator and the device that is used for fuel is injected into this eddy current that is used for producing at the combustion air flow of introducing eddy current, this vortex generator has at least two cone-shaped shell portions, these two cone-shaped shell portions are assembled together and form a liquid, and surround a taper vortex space together, this taper vortex space have cone angle gamma and with the air inlet slit of the length direction of cone tangent (or along the length direction of cone tangential).
Background technology
From many existing publications, for example wherein two document EP 0 210 462 A1 and EP 0,321 809 B1 the premix burner of known the above-mentioned type.Such premix burner is operated based on the general operation principle that produces in cardinal principle taper vortex generator, this vortex generator provides at least two with the suitable cone-shaped shell portion and the eddy current that are assembled together of stacked mode each other, this eddy current comprises fuel and AIR MIXTURES, and this eddy current is lighted in the combustion chamber in the downstream that is positioned at the premix burner along flow direction, thereby forms the premix flame that occupies stable as far as possible space.In this case, the locus of premix flame is determined by the aerodynamics behavior of eddy current, the vortex coefficient of eddy current is along with along the increase of the propagation of the axis of burner and increase, therefore it is unstable to become, and finally resolve into the vortex ring that is formed with recirculation zone because between burner and combustion chamber, produce discontinuous cross section transition, in its forward region, form premix flame along flow direction.
The aerodynamics stability of formed recirculation zone particularly importantly, but it depends on design, the shape and size of vortex generator in highly sensitive mode.For example, if spatially not really stable foremost at the flow direction of formed recirculation zone, then hot acoustic vibration or pulsation will take place in combustion system to the degree of increase, and this will significantly damage the release of whole burning and heat.
Consider this fact, the overall dimension of the premix buner system of previously known and use is limited, and wherein the maximum combustion device diameter at the burner outlet place only is 180mm.Such premix burner also have relatively point, promptly be less than or equal to 18 ° than small-angle, so the length of burner trend is bigger with respect to the diameter of for the downstream burner, handles but still can carry out I﹠ M to it well.
But so long as will light the burner of large-size, it is made by so-called multiple burner apparatus up to now, and has used aforesaid mixed type burner.For example DE 42 23828 A1 or DE 44 12 315 A1 disclose such multiple burner apparatus.For operational example as being suitable for lighting this multiple burner apparatus of silo-type combustion chamber, need be by the complex configurations of a large amount of premix burners that are used separately as main burner or auxiliary burner, so that realize allowing in whole load range end effect with alap emission value continued operation combustion chamber.
But, needn't accept simultaneously under the situation of the mass loss in the combustion process, wish the quantity that reduces complexity and be used to light the independent premix burner of large-size combustion chamber.In addition, because the environmental standard about the increasingly stringent that reduces the emission value its objective is by the buner system that more meets the modern environment standard, is easier to accept to substitute the single diffusion burner of before having operated of lighting large-sized silo-type combustion chamber that is mainly used in.Particularly, be desirable to provide large-sized as far as possible premix burner, only adopt single premix burner that this silo-type combustion chamber is operated so that can continue to keep about avoiding high conversion and very first time procurement cost.
Theoretical research and test show, the bipyramid burner of knowing from EP 0 321 809 B is carried out simple scaling can not realize above-mentioned purpose, and this mainly is because the length of burner will disproportionately increase.In addition, another fact is can pass its width that flows in vortex generator with the air inlet slit that produces required eddy current along the combustion air that extends with the tangent direction of the axis of burner and introduce will increase equally pro rata, thereby can not guarantee that the combustion air of fuel and introducing is mixed well and have suitable quality.
When needing increased in size or increase the output quantity of known premix buner system, the downstream terminal of the cone-shaped shell portion in the vortex space that another extremely important and very crucial simultaneously aspect is the encirclement vortex generator, in the example of the bicone burner of describing in EP 0 321 809 B1, it ends at the axial orientation block piece.These block pieces help the formation of the separation vortex do not expected, and the separation vortex of the spiral structure that this conduct is relevant causes the unstability of burning, and produces hot acoustic vibration or pulsation thus.
Also have some to be different from other known premix burner apparatus of above-mentioned premix burner (as US 5,588,826), these premix burner apparatus have the transition geometry that for example is hollow cylindrical fixed tube form between vortex generator and burner.But because this regional flow separation can cause backfire or spontaneous combustion, such transition geometry is extremely responsive aspect aerodynamics.Similarly, because its complicated production process, such transition geometry has improved production cost undoubtedly.
