INSTALLATION FOR BURNING LIQUID FUEL Filed March 7, 1939 ADOLF BAResaor: R
. INVENTOR 31 AITORNEY- UNITED STATES PATENT OFFICE INSTALLATION. FOR FUEL Adolf Bargeboer, The Hague, Netherlands I Application March 7, 1939, Serial No. 260,263
4 Claims.
At installations for burning liquidfuel with wide range burners of the return flow type (as f f. i. U. S. A. Pat. 2,079,430) and where the fuel is supplied to the burners by a high-pressure Q pump, it is common practice that the return fuel flows back into the suction lead of the highpressure pump. 7
In many cases these installations suffer of troubles such as unstable burning, undesirable variations in pressure and, in serious cases, a collapse of the pressure and extinguishing of the flames.
The invention eliminates these troubles completely by supplying the fuel to the high-pressure pump under a positive pressure, while the 4 return fuel flows into the supply lead at a point where said positive pressure prevails.
This may be understood from the results of research about the abovementioned troubles. It has been shown that these troubles were due to vapour-lock phenomena of the fuel which contains often high volatile components, especially where the fuel, as in most cases, is pre-heated.
These volatile components are liberated by the vacuum-shocks in the liquid which are caused by the irregularities inthe working of' every pump, while these so liberated gases do not resolve or condense afterwards. So these phenomena give rise to gas-accumulation at the suction-side of the high-pressure pump, and so cause irregularities, and under severe circumstances, break-down of the pump-action.
Now it is clear that by supplying the fuel under pressure to the high-pressure pump, these dangerous vacuum shocks cannot arise, and so the formation of gasis eliminated.
Figs. 1, 2 and 3 give schematically some instances of the invention.
In Fig. 1, the high-pressure pump I (f. i. -20
atm.) supplies a greater quantity of fuel to the burners 2 than is burned. The return (surplus) fuel flows via the non-return valves 3 and leads 4 to the collective return lead 5, which issues into the supply lead 6 and the hot-filter I2 of the high-pressure pump I. Fresh fuel is supplied under pressure (f. i. 1-6 atm.) by the lowpressure pump which sucks the fuel from the tank 8 via a filter Ia. As low-pressure pumps are not so liable to shock action they do not give rise to vapour-locks. Moreover, in cases, where the fuel is pre-heated, as generally occurs, the heater II may be inserted between the low-and high-pressure pumps, so that the low-pressure pump does not suck highly heated fuel. This ar- 'I heater, and the necessary hot-filter I2, whiclijn other cases have to be placed in the high-pressure lead due to their flow-resistance, are now much cheaper due to the fact that they need not resist such a high pressure.
The capacity of the burners may be controlled by a valve I3. This may also be done by controlling the capacity of the low-pressure pump I, f. i. by adjusting the valve Id. The two pumps I and I, may be built together as two stages of a unit. I
Another method of applying the invention is explained in Fi s. 2 and 3. I
Here the return fuel flows through an injector I5. By the energy of the return fuel which enters at considerable pressure through the nozzle I6, the fresh fuel is sucked from the tank I! through pipe I8, and is pressed from the part I5a of the injector under considerable pressure through pipe 20, heater I9, lead 20 to the highpressure pump 2|. This pump supplies the fuel to the lead 22 and the pipes 23 to the burners 24. The return fuel flows through leads 25 and the collective return lead 26 to the injector.
The capacity of the burners may becontrolled in the ordinary way by a valve 21. A far better way is attained by varying the opening of the nozzle I6 f. i. by an adjustable needle 28. By opening the nozzle, more fuel is returned and the capacity of the burners decreases. As with ,increasing returned fuel quantity the return pressure decreases in about the same proportion,
v emcient and simple way.
rangement' has also the advantage that this the energy of the injector remains approximate 1y constant over thewhole range, and the injector action is always sufiicient.
Together with this pressure action and the excellent mixing of the hot return fuel with the relative cold fuel from thetank, the device eliminates the above mentioned troubles in a very With the lead 29 and the valve 30 the fuel may be circulated at the starting.
With control valve 3| the-pressure of the highpressure pump I may be regulated.
The surplus fuel of the pump 2| may be returned through the by- passes 32 and 33.
If the return fuel from the pump 2| flows through the lead 33, the back flow assists the action of the injector.
In order to prevent inverse fiow from the injector to the tank, a check valve 36 is inserted into lead I8 and an emergency suction lead 34 with check valve 35 provides the possibility of sucking fuel directly from the tank I1.
and a supply lead connecting the pressure side 1o of said injector with said pump.
2. An installation, as claimed in claim 1, including means for adjusting the cross-section of said injector nozzle.
3. An installation, as claimed in claim 1, in-
5 .cluding a by-pass connection between said suction lead and pump and a non-retum valve in said by-pass to prevent back flow of fuel to the suction lead.
4.;An installation, as claimed in claim 1, including a non-return valve in the suction lead.
