Definitions
- the invention relates to a method and a device for reducing the oil throughput of a boiler oil burner, in particular in the partial load range, using an oil supply to the oil burner.
- Examples include DE-697 04 464-T2, DE-197 25 266-A1 or DE-43 04 068-A1.
- the electronic control of a heating system is also described, for example only, in DE-195 27-830-C2.
- this object is achieved according to the invention in that In addition to the metering fitting assigned to the oil supply line, a secondary medium, in particular water, is supplied to the oil flow as a function of the burner output.
- Embodiments of the invention result from the subclaims. It can be particularly expedient to supply the secondary medium in the area of a through-hole taper of the oil supply line, this supply being able to take place, for example, via an injection cannula.
- Another design can be that the secondary medium supply is designed as an injection needle, the outlet opening of which is assigned to the tapered oil flow line.
- the secondary supply is carried out by means of an injection needle, simple regulation of the inflow quantities of the secondary medium, e.g. of the water to be injected, in that the injection opening can be changed by variable immersion of the injection needle in the oil flow line.
- the secondary medium e.g. of the water to be injected
- a floating ball shut-off valve for preventing air from entering the secondary medium supply suction is assigned if there is no secondary medium.
- a device features also by a control system for switching off the secondary medium supply and maintaining an oil supply to the burner before switching it off to ensure the filling of the oil supply line to the burner, exclusively with oil without secondary medium.
- FIG. 1 is a simplified schematic representation of an oil burner with a secondary medium supply fitting according to the invention
- FIG. 2 shows an embodiment of the device according to the invention in detail in a side view
- FIG. 4 shows a floating ball shut-off valve in section, Fig. 4a the floating ball shut-off valve in supervision and in
- FIG. 1 schematically shows an oil burner 1 with an upstream oil pump 2 in the oil supply line 3.
- the oil is supplied from an oil reservoir, not shown, via a line 4 to the device according to the invention, generally designated 5, which has a through bore, generally 6 designated, is equipped, which decreases in cross section, so as to form a storage space, designated 7 in Fig. 3.
- a secondary medium supply line 9 is provided in the area of the taper designated by 8, the secondary medium, e.g. Water, which is fed via a reservoir 10 to the feed line 9, with the interposition of a controllable valve 11.
- FIG. 2 shows details of the device 5 in a view, this figure shows the secondary medium supply line with valve 11 and a gravity metering device, generally designated 12, which also has a corresponding valve 13 shown in section in FIG. 4.
- the secondary medium is supplied from below via line 9 to device 5 (in the figure).
- a cannula 14 is immersed in the corresponding oil line 3 the cannula, ie in its outlet opening 15, is immersed from above by a regulating pin 16, the immersion depth of which can be adjusted into the cannula 14 via a threaded element 17 and a screw cap 18.
- the regulating pin tapers towards its tip, this area is designated 16a in FIG. 3, so that the outlet opening 15 can be enlarged and reduced.
- FIG. 3 it is also indicated that the diameter of the oil inflow line 3 can be adapted to the respective burner data by means of plug-in sleeves, generally designated 19.
- FIG. 3a shows a modification with an insertion sleeve 19a for adapting the cross sections of the storage space 7 or the taper 7a.
- the floating ball valve shown in FIG. 4 as an example is assigned to the secondary medium supply line 9 and consists of a shut-off ball 20 in a valve seat 21, which as a rule floats in the secondary medium and rests on an upper grille 22 in the direction of gravity and thus releases the valve seat 21. Sinks the liquid level accordingly, the floating ball 20 also drops and lies down, finally in the valve seat 21 and shuts off the secondary medium supply line, designated 9 'in FIG. 4, so that no air can be sucked in.
- Fig. 5 a control diagram is shown, here it depends on the delay switch relay designated by 23, which ensures that the solenoid valve (MV) designated by 24 for the secondary medium (H 2 0) is closed when the controller shuts down causes the burner, whereby the time delay in the oil supply ensures that the oil supply to the burner is maintained until it is ensured that there is no secondary medium in the supply line to the burner.
- the delay switch relay designated by 23, which ensures that the solenoid valve (MV) designated by 24 for the secondary medium (H 2 0) is closed when the controller shuts down causes the burner, whereby the time delay in the oil supply ensures that the oil supply to the burner is maintained until it is ensured that there is no secondary medium in the supply line to the burner.
- the described embodiment of the invention can be modified in many ways without departing from the basic idea.
- the supply of the secondary medium can be electronically controllable depending on the burner temperature or depending on the exhaust gas values u. Like. more. This possible electronic control is indicated in dashed lines in FIG. 2 and provided with the reference symbol 25.
