DESCRIPTION:
BRIEF SUMMARY
This invention relates to a device according to the introductory part of claims 1.
The invention relates more specifically to a new design of oil burners for oil-heated boilers, furnaces and so on.
Burning of pellets is for instance made in belt furnaces where the heating of the furnace is made by burning oil that is squirted into the furnace together with compressed air via a burner nozzle. The effectivity and the oil consumption are depending upon how well the oil is decomposed by the air before burning takes place.
Conventional design of burner nozzles makes that the oil is decomposed into the form of drops. Drawbacks of the known technique is a bad atomization of the oil particles, a high air and oil consumption and a bad adaptability of the flame. Furthermore, the oil burners have a short length of life due to high environment temperatures that demolish the oil burner.
The object of this invention is to provide an improved device of the kind mentioned above and this object is achieved by giving the device the characterizing features mentioned in the claims.
An advantage with the invention in comparison with known technique is that the invention offers a device that makes a high degree of atomization of the fuel possible before the fuel-air mixture leaves the device.
Further advantages of the invention in comparison with known technique is a reduced fuel and air consumption, a longer length of life of the burner nozzle and the burner, a high adaptability of the length and the width of the flame and that the nozzle besides that can be used for solid fuels like pulverized coal fuel.
A further advantage of the invention is that the burner can be used for working temperatures from 0.degree.-1300.degree. C. This has resulted in that bottled gas systems for temperatures up to 100.degree.-150.degree. C. previously used for dry heating of furnaces, burners for thin oil for temperatures up to 600.degree. C. and burners for thick oil for temperatures from 600.degree.-1300.degree. C. have been able to be replaced by one single burner of the kind according to the invention.
Below an embodiment of the invention will be described with reference to the accompanying figures where
FIG. 1 schematically in interrupted longitudinal section shows an embodiment of the device according to the invention;
FIG. 2 shows in larger scale in longitudinal section a front portion of the device;
FIG. 3 shows schematically in longitudinal section an alternative embodiment of the front portion;
FIG. 4 shows schematically in an end view the front portion according to FIG. 3;
FIG. 5 shows schematically in longitudinal section another alternative embodiment of the front portion.
According to FIG. 1 the combustion device comprises a burner house 1 composed of a front burner head 2, a middle cylinder-formed main part 3 and a rear end part 4. The main part 3 is herewith firmly connected to the burner head 2 and the end part 4, respectively. The end part 4 is provided with an air inlet 5 for combustion air from a not shown source of compressed air. This source can for instance be the compressed air system being available at the place where the device is used or a separate compressor. The end part 4 is further provided with a central, coaxially threaded opening 6 for receiving a fuel tube 7 with external threads.
The rear end of the fuel tube 7 serves as a connecting part 8 for a not shown conduit for the fuel which preferably is a liquid fuel, as a rule thick oil, but it is also possible to use a solid fuel, for instance a pulverized coal fuel.
The fuel tube 7 is axially displaceable in the burner house 1 by turning and is provided with a key grip 9 for a suitable not shown turning tool in order to facilitate the turning. A locking nut 10 is applied on the outside of the fuel tube 7 and arranged to lock this one in a desired position. The front end of the fuel tube 7 has internal threads and is intended to be screwed together with an oblong nozzle body 11 having external threads. In FIG. 1 the parts are shown in a condition where they are not
