Definitions
- the invention relates to an oil firing system for combustion under reduced Nitrogen oxide (NOx) emissions, especially for higher performances, with at least a centrally arranged atomizer nozzle and associated ignition device as well as a fan for the supply of combustion air, which by a Flame tube surrounding atomizer nozzle downstream of the atomization chamber is fed to the nozzle.
- NOx Nitrogen oxide
- Oil combustion plants of the type in question work for the purpose of reduction the thermal nitrogen oxides with exhaust gas recirculation designed in many ways. This leads in part to flame instabilities with a high level at the same time equipment expenditure.
- the invention has for its object an oil combustion system of the beginning to provide the type mentioned in which the distribution is as homogeneous as possible of fuel, air and exhaust gas is given and at avoidance targeted or separate external exhaust gas recirculation the formation of thermal NOx is reduced.
- a core flame and an enveloping flame around it Core flame around which is reliable regardless of the geometry of the firebox and burn stably.
- a fuel gasification and mixing zone In the combustion chamber area after the central nozzle surrounding atomizing nozzles one reaches a fuel gasification and mixing zone. Here the components become more atomized Fuel, air and exhaust gases flowing back internally in the combustion chamber are premixed intensively.
- the heat emission from the core flame supports fuel gasification.
- the aim is a homogeneous mixture with the result of an equalization of the Flame temperature at an overall reduced average temperature level in the flame, which in turn causes a good burnout in the entire flame area is achieved.
- the core flame is preferred through a central atomizing nozzle produced in combination with a mixing system of conventional design, which can be yellow at the core. In the area of the flame one reaches bluish Burnout and overall a slim flame shape without clouding of Fuel.
- Ring disk bluff body arranged to the central atomizer nozzle or the central mixing system can be arranged with gap formation. This gap formation is important for the air introduction to the central flame.
- the central atomizer nozzle or Mixing system complete with the ring disk bluff body in the direction of Longitudinal axis of the flame tube in different positions - in particular infinitely adjustable. This can adjust the air supply adjustment serve the amount of fuel when the load changes, otherwise can this shifting option enables the NOx values to be set or optimized to reach.
- they have the central atomizing nozzle surrounding atomizer nozzles at a narrower spray angle than that the central nozzle.
- the spray angle is preferably the surrounding one Atomizer nozzles selected around 30 ° to 45 °. Because of this narrow spray angle it is achieved that the combustion chamber wall is not wetted with oil. About that In addition, coking in the area of the flame tube mouth and the Avoid adjacent areas on the outer edges of the bluff body.
- the annular disk bluff body is on it the outside facing the combustion chamber, i.e. the centrally located one Atomizer nozzle - pilot atomizer nozzle - side facing away, with an in this direction projecting essay, preferably continuously is ring-shaped and in particular the annular inner edge of the annular disk bluff body arranged immediately afterwards is.
- the attachment can be formed in one piece on this bluff body ring disk be.
- the bluff ring washer on its outer edge again with regard to the combustion air supplied downstream of the combustion chamber have facing projecting edge edging, which are related with the flame tube to improve airflow.
- the Purposes can also be a tapered design of the flame tube on serve downstream end of the combustion air duct.
- the bluff ring washer in the areas the respective ring around the central pilot atomizer nozzle Main atomizer nozzles with radially inward bulges be provided.
- the annular disk bluff body or physically considered the bluff body annular disk of the kind described makes it possible in particular to use nozzles with large Spray angle - 60 ° - to use and even with this large one Spray angle an impact and caking of oil droplets on the front to prevent the bluff ring. If the Mixing device is moved back accordingly, there is also Danger of contamination of the ring-shaped side atomizer nozzles. This measure further reduces NOx emissions and improves combustion overall, i.e. Soot formation is reduced and the combustion approaches that of gas. It takes place a flow equalization with the result of higher flame stability.
- the main atomizer nozzles arranged in a ring around the central pilot atomizer nozzle can be used Star-shaped "to the oil supply and oil return line in the sense of an oil supply pressure source and a common oil return, which are provided for all main atomizing nozzles feeding and discharging.
- the main atomizing nozzles are in the form of a ring line with regard to both their oil flow and their oil return connected to each other, i.e.
- main atomizer nozzles are connected in their base area to this ring line, which in turn is centrally connected to the oil supply pressure source and the oil return line, preferably in such a way that these ring lines between two adjacent main atomizer nozzles provide a feed or discharge point for one have a central oil supply pressure line and an oil return line.
- the prescribed central supply of the main atomizer nozzles arranged in a ring secures you - ultimately also by sufficient cross-section of the feed and Discharges - even operation of these nozzles, i.e. Ejection of the sprayed Oil under practically matching conditions.
- Figure 1 shows a cylindrical flame tube 1, at the outlet of which the combustion air is accelerated, for example by moving in the direction of flow conically tapering section 9, is in its tube axis - i.e. in the middle - a central atomizer nozzle 3 as part of a mixing system of the usual type arranged.
- a central atomizer nozzle 3 Around this central atomizing nozzle 3 - pilot atomizing nozzle - there are several more on a concentric circle with radius r Atomizer nozzles 2 - main atomizer nozzles - arranged.
- the central nozzle 3 is used to supply fuel to a pilot flame, and concentrically the main part is supplied around these atomizing nozzles of the liquid fuel in or with the main combustion air.
- the number of atomizing nozzles evenly spaced on the pitch circle 2, the defined minimum radius 3 of the pitch circle to the central nozzle 3 and the nozzle outlet conditions depend on each other.
- the nozzle outlet holes of all atomizers on the concentric pitch circle are in the direction of flow, or in the air outlet plane of the Flame tube.
- the ratio of the distribution of the total amount of fuel supplied for the Pilot flame to the atomizing nozzles 2 of the pitch circle is an essential one Criterion for combustion with low NOx emissions. (approx. 2 - 5% of the Total fuel quantity at high load is required for the central pilot flame).
- the main combustion air is applied to the flame via the ring cross sections fed to the exit plane of the flame tube 1.
- These ring section cross sections result from the respective flame tube inner diameter, one for Flame tube axis coaxially arranged bluff body 4, e.g. executed as Washer, and the atomizer nozzles 2 on the concentric pitch circle.
- the Another disc damper is integrated coaxially into the annular disc bluff body 6. Both bluff bodies are through an annular gap for combustion air passage Cut.
- the central volume bluff body has adjustable combustion air inlet cross sections in a prechamber 7.
- the end of the prechamber 7, in Seen flow direction, is with a bluff body 8 with radial flushing slots, a center hole and one on the outside diameter, in the direction of flow standing collar, closed.
- the annular disk bluff body 4 improves the operating behavior.
- the individual fuel-gas mixture partial flows mix completely with the pilot flame according to the minimum path length and ignite in the process - the main flame stabilizes. In this main flame there is a uniform, complete combustion of the individual partial mixture flows at reduced O 2 partial pressure. (Burning phase).
- the thermal NOx formation in the Flame significantly reduced, reduction 30-40%, with a good rating at the same time of the other operating parameters.
- the firing starts with the electric Ignite the pilot flame and switch on the atomizer on the pitch circle. It this creates a continuous slim, focused flame. The flame burns with a yellow core and blue border areas.
- Figures 2 and 3 show perspective views of the central mixing system with the central atomizer nozzle 3 and three arranged circumferentially to this Main atomizer nozzles 2.
- the in connection with the schematic embodiment Reference symbols used according to FIG. 1 are found in the same Way again in these drawings.
- the three are Main atomizing nozzles arranged around the central pilot nozzle or the mixing system in a base area 18 via two ring pipes connected, one of which is the oil supply line under constant pressure 14 and the other symbolizes an oil return line 15.
- the care of Atomizing nozzles by means of a differential pressure between a supply pressure and a return pressure is generally known.
- This oil flow and oil return system ensures that all of the Main atomizer nozzles work practically under the same operating conditions, so that the oil atomization around the pilot flame is stable.
- Figures 2 and 3 leave a special design of the ring disk bluff body 4 recognize that it surrounds the central atomizing nozzle 3 Internal border has an attachment 10, which serves to ensure that the outside 11 of the bluff body 4 of sprayed oil particles and thus impending Deposits remains free.
- the outer circumference of this annular bluff body 4 is provided with a rim 12, which is interrupted by bulges 13 which are directed radially inwards and the reception of the main atomizing nozzles to serve.
- the central pilot atomizer nozzle 3 or Mixing system together with the annular disk bluff body 4 opposite the ring around these arranged main atomizing nozzles 2 axially to the flame tube 1 be moved.
- the edging 12 and in particular the tapered Section 9 of the flame tube 1 is used to guide the combustion air in the combustion chamber.
- FIGS. 2 and 3 and in particular also FIG. 4 show, the main atomizing nozzles around the central pilot atomizing nozzle are connected to one another in their base region 18 by two parallel ring lines 14, 15, one 14 of which supplies the oil supply and the other 15 the oil return forms.
- These ring lines are intended to ensure that the pressure behavior is as equal as possible - constant oil supply pressure and controlled oil return pressure depending on the desired mode of operation. This can be achieved by appropriately dimensioning the diameter of the lines and thus negligible flow resistances.
- connection of the ring lines 14 and 15 to the central oil supply that is to say an oil pressure source relevant for all main atomizing nozzles on the one hand and oil return on the other hand, can be achieved in that the ring lines 14, 15 via T-shaped branch points are tapped ".
- valve device is provided in each of the main atomizing nozzles is provided, both the oil supply line and the oil return line separates from the nozzle mouth when burner operation is interrupted becomes. This is of particular importance at the end of the operating intervals because then there is a tendency to drain oil through the nozzle into the combustion chamber, which leads to contamination etc.
- the valve device is basically hydraulic, i.e. depending on that by controlling the flow the oil return line actuated, in such a way that are under spring tension Valves react according to the pressure conditions to be set, i.e. in the event of interruption of the burning operation by pressure build-up in the closing direction Valves, however, in operation through their opening.
- valve devices are located between the the ring lines of the oil flow and the oil return base of the respective nozzle lance of the main atomizing nozzles 2 and their nozzle head, such as this can be seen in particular in FIG. 2.
- the valve device arranged in this way each nozzle lance is surrounded by a jacket.
- Figure 6 is a circuit diagram for an oil firing system with three around a pilot nozzle main atomizer nozzles arranged around, each in the oil supply as in the oil return with two spring-loaded, hydraulically connected in parallel actuated valves is provided, two for each oil path for space or availability reasons.
