GAS PRDDUCER.
-Application filed April as, 1322. Sea-Balm, 555,771.
vide an im roved gas producer of the underfeed type in which the fuel issupplied continuously b mechanical means.
Compare with the known apparatus of this type, the improved gas producer works in the reverse direction. The blast is led to the surfaceof the fuel that has been reduced to ashes, and the ashes are simultaneously removed from the gas producer at that point.
A constructional form of the improved gas producer according to this invention is illustrated by way of example in the accompanying drawing in vertical section.
Referring to the drawing, the producer shaft '1, the cross-sectional area of which increases towards the top, has an upper part 2 of refractory brickwork, its lower part 3, which is provided with outlet openings 31 for the gas, being iron. A fuel-feed pipe 4 having a mouthpiece 5 is connected up to the lower part '3 of the shaft so as to form a continuation thereof.
Around-the lower part 3 9f the shaft is an annular chamber 6 enclosed by the cylindrical sheet metal casing 7 and a base plate 8. This annular chamber 6 which also serves asa gas receiver, is extended downwardly so as partly to surround the fuel feed pipe 4 for the purpose of preheating and drying the fuel. Instead of the gas receiver 6 surrounding the upper portion of the fuel feed pipe 4, a separately heated chamber may be provided, which at its maximum temperature will produce partial dry distillation of the fuel in the pipe 4. From the gas receiver 6 the gas is drawn through the pipe 9 into the main 10.
The fuel is fed to the producer by means of a rotary feed plunger 11 having a lower screw-threaded portion 11 which fits into an internally screw-threaded pedestal 1:2, The feed plunger ll-is provided with a driving gear 13 by means of which it can be rotated and simultaneously raised and lowered by the interaction of the screw-threaded portion 11 with the internal screwthread of the pedestal 12. The fuel is supplied by means of a hopper 14 to a feed tray 15 having a base plate 16 in which the feed plunger is guided. The fuel is passed -to the centre of the feed tray 15 above the piston 11 by means of a revolving annular member l'Z supported on antifriction rollers and fitted. with a number of scraper blades 19 fixed to scraper arms 18.
In the operation of the improved gas producer, the feed plunger 11 moves continuously up and down, and receives from the base plate 16 of the tray 15 a. determined quantity of fuel which it forces into the mouthpieceb and thence to the shaft 1.
In order to prevent the fuel that has already been fed by the plunger from dro ping back, the cross-section of the mout piece 5 is increased above its inlet end in] such a'manner that an annular surface 20' is formed which provides a supporting ledge for the fuel.
It is necessary for the piston 11'to rotate in order to help it detach itself from the 7 fuel. The top 21 of the piston 11 is pref-- 90 erably convex in order that the bottom surface of the fuel in the mouthpiece 5 will be concave. In the case of dry fuel, such fuel is preferably moistened with a liquid such as water, 011, tar, and the like, at its surface'of contact with the piston.
The lower part of the generator has a very much smaller diameter than the ugpler part, and therefore, in order that the 21 shall not be pressed up into the shaft in the form of a core of smaller cross sectional area which, on arrivingat the top, would break up and roll about inside the shaft distributing means are provided in the shaft,
consisting of a pointed solid core 22 from 05 which partitions 23 extend radially out wards. Between these radial partitions 23 are arranged concentric partitions 24: held in place by means of tongue-a-nd-groove joints.
The paititions 2-l may be set at any desired I angle to the vertical for the purpose of deflecting the ascending fuel more towards the centre or more towards the outside as required.
The radial partitions constitute gas. outlets which communicate with the outlet openings 31 in the lower part 3 of the producer. By this means an exceedingly uniform withdrawal of the gas is provided for over the entire cross section of 110 the shaft.
The air for the generation of gas-1s sup- 23 are hollow and v is open at the top "to admit the air for the generation of gas and allow the discharge of the ash, means for feeding the fuel from the bottom towards the top of the shaft, means for withdrawing the gas from below the ash zone without passing through the ash zone, whereby the combustion is caused to take place at the top of the shaft, the ash zoneto remain at the top of the shaft, and the air to be supplied to the fuel through the ash zone. 1
2. A gas producer of the downward combustion type having the ash zone at the top of the producer shaft comprising-in coinbination a producer shaft the cross-sectional area of which increases towards the top and is open at the top to admitthe air for the generation f gas and allow the discharge of the ash, means for feeding the fuel from the bottom towards the top ofthe shaft, means comprising apertures in the narrow part of the producer shaft below the ash zone for is open at the top to admit the air for the generation of gas and allow the discharge of the ash, a fuel-feed tube delivering into the lower part of the producer shaft, and a, feedplunger capable of rotating and moving vertically into the lower end of said fuel-feed tube for feeding the fuel from the bottom towards the top of the shaft, means comprising apertures in the narrow part of the producer shaft below the ash zone for withdrawing the gas without passing through the ash zone, whereby the combustion is caused to take place atthe top of the shaft, the ash zone to remain at the top of the shaft, and the air to be supplied to the fuel through the ash zone, as set forth.
in testimony whereof I have signed my name to this specification.
