The device is intended to be utilized in both heating boilers and internal combustion engines and in turbine aeronautical motors too, or generally in all those applications in which one has the combustion of a liquid fuel.
- By gasification, the generation is meant of aeriform substances by transformation of solid and liquid fuels. The interest is addressed in the present invention to liquid fuels, the gasification of which brings noteworthy advantages which can be summarized in a complete combustion, given the enormous reaction surface the molecular dispersion ensures between the fuel and the comburant, in a better control of the quantity of air necessary for the combustion, in a long flame, in the possibility of interrupting and restarting the combustion at will, in the possibility of concentrating the flames in a restricted space, and in the possibility of the recovery of the heat by the preheating of the fuel.
- This invention aims at creating a particular burner arrangement that allows an optimum gasification of a liquid fuel while this one is delivered into a combustion chamber.
- Therefore, according to this invention a device is provided for burning gasified liquid fuels, which includes a central control unit, an electric transformer, a centrifugal pump for supplying air as a comburant, a pump for supplying a liquid state fuel, and, moreover, in communication with a combustion chamber.
- A first burner stage has a first piping and a first nozzle for ejecting the fuel in an atomized liquid state. The first piping is connected to the pump for supplying the fuel and endowed with a first solenoid valve for supplying the priming fuel. The ejected fuel is ignited by an electrode excited by the electric transformer under the control of the central control unit. The first burner stage develops a priming flame in a ignition zone of the combustion chamber.
- A second burner stage has a second piping connected to the pump for supplying the fuel and endowed with a second solenoid valve for the steady-state supply of the fuel. The second piping has a gasification tract passing in said ignition zone so as to allow the transformation of the fuel, which passes inside it, from the liquid state to the aeriform state. The gasification tract terminates in a distribution passageway to be distributed in the aeriform state in said ignition zone, to form a combustion flame caused by said priming flame of the first burner, which is cut out after the ignition of the second burner stage.
- This invention is described to an indicative and not limiting object in an embodiment thereof, referring to the annexed drawing.
-
FIG. 1 is a partial schematic and sectional view of a device for burning gasified liquid fuels according to this invention. - Referring to the drawing, one has marked a central control unit by 1, and electric transformer by 2, a centrifugal pump for supplying air as a comburant by 3, and a pump for supplying liquid state fuel by 4.
Centrifugal pump 3 operates to supply air in the direction of arrow F. Such components are assembled in a structure not described and illustrated in detail, but within one skilled in the art. Such a structure is applied in a manner which passes through the interior of acombustion chamber 5, to the wall of which, in arefractory material 6 andmetal sheet 7, it is fixed by bolts schematically shown at 8. As shown, the combustion. chamber is surrounded by a hollow space orfumes box 20 for the exhaustion of fumes through aport 21, which also operates, in a rear part thereof, as a heat exchanger for an upper part of achamber 22 for drawing heated air, indicated by arrow A for the combustion.Chamber 22 for drawing air is connected through apiping 23 tocentrifugal pump 3 for supplying air. - A
first piping 9 terminating in afirst nozzle 10 for ejecting atomized liquid state fuel is connected tosupply pump 4.First piping 9 is endowed with afirst solenoid valve 11 for supplying fuel. The ejected fuel, by virtue of the fine crumbling of the droplets, is ignited by anelectrode 12, which, connected to theelectric transformer 2, is excited under the control ofcentral control unit 1. A first burner stage is so realized, which develops a priming flame in anignition zone 16 ofcombustion chamber 5. A second burner stage is formed of asecond piping 13 connected withpump 4 for supplying the fuel and endowed with asecond solenoid valve 14 for supplying the fuel at steady-state.Second piping 13 has agasification tract 15, formed as a pipe coil, which passes through theignition zone 16 ofcombustion chamber 5. Asignition zone 16 is heated by the priming flame, ingasification tract 15 ofsecond piping 13, one has the transformation of the fuel, which passes inside it from the liquid state to the aeriform state.Second piping 13 terminates in adistribution passage 17, preferably cylindrical, to be distributed in an aeriform state inignition zone 16. A combustion chamber is formed therein, caused by the priming flame of the first burner. Thereafter, the priming flame is cut out controlled bycentral control unit 1. Aphotoelectric cell 18 for controlling the flame is connected withcentral control unit 1. As soon asphotoelectric cell 18 sees the flame in a steady state, it sends a signal of consent to regular operation tocentral control unit 1. These interactions are schematically indicated by arrows without reference numbers. The burner in its steady state continues the regular operation, tillphotoelectric cell 18 sees the flame burning. The flame in the steady state frees fumes schematically indicated by lines with arrows in succession, marked with f. - It is clear that
gasification tract 15 is to be realized in a material fit for withstanding the temperatures of the flame in the steady state of the second stage of the burner, which it is subjected to when the priming flame is cut out and only continues the combustion of the fuel coming out of the passageway for the distribution of the fuel in aeriform phase. - Suitably, a
governor 19 of flow of fuel toburner 17 is envisaged in the second piping.Governor 19 of the flow of fuel, which serves to adjust the flame at the steady state, can be realized under the form of a calibrated-hole plate, interposed in the fuel flow. - As regards the supply of air,
centrifugal pump 3 for supplying air as a comburant draws air for combustion in an upper part ofchamber 22 for drawing air. In this way, the supply air is heated at the expense of the exhaust fumes. So, the temperature can even be increased in the combustion chamber, achieving an optimum combustion, substantially devoid of unburnt particles. The environmental pollution is also reduced in such a way. - It should be apparent that the gasification tract could be externally endowed with other means for heating the fuel which passes inside it, such as an electric resistance, which cooperates with the gasification of the fuel under the control of the central control unit.
- The device according to the present invention can be applied to normal boilers which burn liquid fuels, but also to the combustion in other fields, such as turbine aeronautical motors and internal combustion motors.
- Though not being part of the present invention, the fact is to be taken into account that in combustion motors having traditional carburetion, the position of the chamber having a float and metering rod is to be modified to reduce the excessive inflow of liquid fuel. After the chamber having a float and metering rod, positioned downstream of the pump for supplying the fuel, the pipe coil of the device according to this invention, is foreseen coiled around one of the pipes for exhausting fumes. In this way the liquid fuel is allowed to pass to the aeriform. state and to arrive in this state into the combustion chamber of the motor. It is apparent that in this way, the environmental pollution is lowered, whilst the fuel consumption is reduced.
