Description
Technical field
The present invention relates to a kind of burner that is used for the used heater of motor vehicles especially, the baffle plate that it comprises roughly axisymmetric combustion chamber and is arranged in described combustion chamber.
Background technology
These burners that are also referred to as atomising burner or atomizer burner are particularly useful in the motor vehicles used auxiliary heater and separate heater.
These burners have numerous requirements, especially about reliable and highly do not have the starting performance of discharging and smooth combustion moves.And, need to make great efforts to make up the heater that can be used for different installation sites.
Aspect starting performance, various operational factors are coupling mutually.On the one hand, must in the process of burner starting, make the starting district can obtain abundant relatively fuel-air mixture, yet, on the other hand, need the primary combustion air of sufficient quantity again, to guarantee that fuel is transported to the starting district from the fuel pin.
The requirement that allows heater to have different installation sites is associated with the problem that relates to starting performance.Specifically, for the primary air that transport of fuel has seldom to the starting district being supplied with, the tolerance of having in the past makes the directed fuel pin in outlet directed downwards ground; This has caused whole burner to have to be installed on the vertical installation site.
In order to ensure the stable burning operation of burner, must satisfy conflicting requirement in addition.On the one hand, always require fuel and air well to mix, and on the other hand,, can poorly cause too high AIR Proportional and severe excessively rotation again in the core district of flame especially at start-up period.
Summary of the invention
The objective of the invention is to overcome at least in part the described problem of prior art, especially make it possible to have the seldom starting performance of the reliable and low emission of dense smoke in different installation site acquisitions.
Above-mentioned purpose is realized by the feature of independent claims.
Favourable improvement of the present invention provides in the dependent claims.
The present invention is based on a class burner, and baffle plate has qualification bend in the axial direction, and has the bend on the direction of burning-out zone.Based on the bend of baffle plate, can limit temperature independently and be shaped baffle plate.For making flat prior art baffle plate, not this situation, this is owing to the thermoinducible change of shape of the combustibility of burner can occur influencing unfriendly.Curved by direction up-bow at burning-out zone, can in the zone of priming chamber, obtain sufficient space.And, have been found that the bend on the direction of burning-out zone can not have a negative impact to the mobile performance in this district.Especially, rotating countercurrent zone is significantly kept in the radially inner side zone of burning-out zone.
According to a preferred embodiment of the present invention, the periphery of baffle plate defines a plane, and baffle plate to the diameter ratio of the maximum axial distance on described plane and baffle plate between 0.07 and 0.21.The curved harmful point preferred center that is in structure basically on radial coordinate of going through most of baffle plate up-bow.The axial distance on the described plane that periphery limited to baffle plate is defined as to become designated ratio with described diameter.
Thus, particularly preferably, baffle plate to the maximum axial distance on plane and the diameter ratio of baffle plate is about 0.14.For example, the diameter of baffle plate is about 40mm, and bend has the value of about 5.7mm.
According to a particularly preferred embodiment of the present invention, has the burner nozzle that is used to supply with fuel and primary air, and between burner nozzle and combustion chamber, has heat shield, described heat shield has the opening that is used for secondary air is supplied to the combustion chamber, and described opening is provided with air guide element.Heat shield fundamentally is of value to protection nozzle and fuel supplying part spare and avoids heat in the combustion chamber.And secondary air supplies to the combustion space via heat shield.The opening of the secondary air supply part by being provided with air guide element, described secondary air can be supplied with in a controlled manner, thereby, no matter for starting operation still for continuous operation, all can influence the burning operation in the mode of appointment.
It is useful that air guide element is formed by protuberance, and described protuberance and heat shield integral body are made, and stretch out along the direction of combustion chamber.Described heat shield can be easily for example by make protuberance by v shape stamping tool form, after stamping procedure or use stamping procedure to make protuberance bend manufacturing from the plane of heat shield.
Also the present invention has been carried out useful improvement, promptly protuberance becomes different angle formation with the surface of heat shield and/or the radius of heat shield.If protuberance almost extends perpendicular to the radius of heat shield, then produce strong angular momentum, and become the protuberance of less angle to produce less angular momentum with radius.Become low-angle protuberance to produce to have the air stream of big radial component and little axial component with the surface of heat shield, and for the protuberance that becomes big angle with the surface of heat shield, axial component is preponderated.By adopting this mode, can make secondary air enter into the core district that flame forms with low angular momentum.By adopting this mode, on the one hand, supplied with the required air that burns; But do not influence the excessive angular momentum of the stability of flame unfriendly.Especially, secondary air can be shunted according to the arrangement of each air guide element.
According to another embodiment, protuberance becomes substantially the same angle to be grouped according to the radius with the surface of heat shield and/or heat shield.The flow regime that limits in the combustion chamber is arranged by the collective of protuberance and is formed.
In addition, the present invention implements valuably like this, that is, burner has burning-out zone, and the secondary air that supplies to burning-out zone has higher angular momentum than supplying to the secondary air that starting distinguishes.In the expectation burning-out zone high angular momentum is arranged.Especially, radially inner side rotation countercurrent zone has strengthened the after-flame effect, and makes combustion chamber volume be utilized effectively.
In addition, heat shield has the opening that passes through for igniting element.
According to a particularly preferred embodiment of the present invention, burner nozzle has the primary air supply part that is used to supply fuel to the fuel pin of burner and is used for combustion air is supplied to burner, and by selecting the internal diameter of fuel pin, the start-up period that the rate of outflow of fuel is predetermined to be at burner is essentially the not fuel arrival starting district of atomised form.Compare with the fuel pin in the heater of prior art, by reducing the internal diameter of fuel pin, under identical fuel delivered volume, the rate of outflow of fuel increases.By adopting this mode for any installation site, the fuel injection that exports from the fuel pin all can arrive the starting district.Especially, for little primary air amount, the primary air of supply should only have very little angular momentum, and the injection of the fuel of atomizing can not arrive the starting district basically.Thereby burner starts reliably, and has obviously reduced the formation of dense smoke in the starting process.
Preferably, the internal diameter of fuel pin 0.5 and 0.7mm between.Compare with the rate of outflow of the fuel pin of the prior art of internal diameter about 0.8mm, internal diameter 0.5 and 0.7mm between the rate of outflow can almost double or even reach more than the twice.
Especially preferably, the internal diameter of fuel pin is about 0.6mm.Under described internal diameter, when full-load run, promptly under the fuel mass flow rates of 0.5kg/h, the above rate of outflow of 0.6m/s is possible, and for the internal diameter of 0.8mm, the rate of outflow is about 0.35m/s.Thereby when fractional load was moved, promptly for the fuel mass flow rates of 0.2kg/h, the rate of outflow rose to about 0.25m/s from about 0.14m/s.For correspondingly choice structure characteristics or operational factor, even the traditional fuel pin that uses internal diameter to be about 0.8mm also can realize arriving starting distinguishes the target of atomized spray not basically when heater starts.
It is useful that starting district is made into the priming chamber that igniting element stretches into wherein.The wall of combustion chamber can surround igniting element in this way.In starting operation, the fuel of " ballistic " sprays and can make fuel get wet igniting element and chamber wall this moment, thereby chamber wall and adjacent member are used as the wall evaporimeter after their heating.
The present invention is based on following discovery, i.e. Xin Ying curved baffle especially can be improved the runnability of burner greatly with the combination of the fuel supplying part spare of novelty and novel heat shield.This relates in particular to stability and burner multiple possible installation site in motor vehicles of starting performance, burner operation.
