F. L. DUFFIELD GAS PRODUCER Filed Jan. 10, 1924 FIG 2 FREDERICK LINULE .DUF'FIELD,
Patented Nov. 20, 1928.
, UNITED STATES FREDERICK LINDLEY DUFFIELD, OF BRASSINGTON, ENGLAND.
GAS PRODUCER.
Application filed January 10, 1924, Serial No This invention relates to gas producers.
The object of the invention is to provide a gas reducer with means for introducing pow ered carbonaceous matter together w1th primary air and steam into a gas generating chamber to cause gasification and means for delivering secondary air properly distributed to unite with the gas thus produced in the chamber.
To this end, I utilize a gas generating chamber of conoidal form having an outlet in its roof and an opening in its base in combination with'a trough for water positioned below said opening into which the hot ash from the chamber falls, thereby producing thesupply of steam for the generating chamber. Refractory plates spacedly positioned above the generator outlet are employed to deliver secondary air to mix with the gas as it leaves the generating chamber.
A further object of the invention is to pro-.
vide means for removing the ashes from the trough to insure the production of the desired steam Referring to the drawings filed herewith Fig. 1 is a sectional view of such preferred form of my producer, taken on the line 1'1 of Fig. 2; and
Fig.2 is a. plan View of the same while Fig. 3 is a sectional view taken onfthe line 3-3 of. Fig. 1. y
In these figures a is a gas generating chamber of conoidal form supported on a framework 6 of iron or the like. The roof 0 of the gas generating chamber'is preferably arched and provided with a central gas out-let cl. At
the base of the generator is an aperture 0.
Above the outlet d is a refractory plate f carried by supports 9 on the arched roof 0 and above the plate 7 is another refractory plate h, the space 7' between the two plates being adapted for the admission of secondary air through the medium of pipes y'. The members is supporting the top plate h are so arranged as to form a number of radiating or diverting passages m, m, communicating with the space 7' for distributing the secondary air at two sides and the inner end of the plates f and h. Powdered fuel and primary air arefed in a known Way into the gas generating chamber through one or more substantially tangential openings, one being indicated at n.
Below the aperture 6 at the base of the gas 685 296, and in Great Britain March 1923.
generating chamber is a water-trough 0 in which' s disposed a screw conveyor p for discharging the ash from the trough into a collect-ing chamber or receptacle 9.
In use, peat, lignite, charcoal, or coal,.in powdered form or the like containing a small or larger proportion of inert matter is carried with the minimum quantity of air, tangentially into the gas generating chamber maintained at a temperature of about 900 C. to 1200 C. by the gasification of the pulverized material which circulates within the gas generating chamber until the non-combustible matter, gradually descending in its circulation, isat last precipitated into the water trough at the bottom of the gas generating chamber while the carbon and volatiles in the pulverized material are converted by partial combustion into combustible producer gas in a reducing atmosphere with an excess of carbon. The circulation of the pulverized material in the generating chamber affords the necessary time factor for intimate partial combustion in the presence of the required heat to effect the production of gas. Thea'ction of the steam in the water gas reaction produces gas rich in carbon monoxide and hydrogen. The gas emerges from the outlet d at the top ofthe generator and is deflected out-wards by the plate 7 immediately above while the ash descends by a series of tortuous movement-s'to the water in the bottom. The secondary air necessary to cause the combustion of the gases into carbon dioxide and other combustion products is admitted between the two plates f and h and being distributed on two sides and the inner end of the plates readily mixes with the gas, the gas and air being conveyed into the furnace or combustion chamber where it is to be employed. The hot ash dropping into the water. facilitates the production of steam.
The gas producer may be built in the interior of the furnace, viz in the space occupied by the fire grate and fire bridge or may be built away from the furnace and the gases conveyed through mains or pipes with or without tar and ammonia extract-ion. WVhen built in or adjacent to the furnace practically the whole of the sensible heat in, and radiation of, the gas producer is carried tothe furnace.
Alternatively, the plates 7 and h on the roof 0 may be dispensed with and the gas allowed to issue from the outlet d without any obstruction and mix directly with the secondary air.
What I claim and desire to secure by Letters Patent is 1. A gas producer comprising a gas generating chamber of conoidal form having a gas outlet in the top of said chamber, means for introducing powdered carbonaceous matter, means for introducing primary air and means for introducing steam for causing gasification within the gas generating chamber, means for admitting secondary air to mix with the gas, said'means comprising refractory'plates spacedly positioned above the outlet in the top of said generator, means for admitting the secondary air between the said plates for causing thedistribution of said secondary air, said means including members arranged between said refractory plates and constituting supports to the upper of said plates and forming a number of diverging passagesbetween them, and means for supplying steam to the generator.
2. A gas producer comprising a gas generating chamber of conoidal form having a gas outlet in the top, means for introducing powdered carbonaceous matter into the gencrating chamber, means for introducing primary air and means for introducing steam for causing gasification within the chamber, means for admitting secondary air to unite with the gas, said means comprising refractory plates spacedly positioned above the gas outlet in the chamber, means for admitting theseconda-ry air between the said plates,
means provided between said plates for distributing said secondary air, and means for supplying the steam to the generator from an aperture provided in its base.
3. A gas producer comprising a gas generating chamber of conoidal form having a gas outlet in the top, means for introducing powincluding a Water-containing trough positioned below said aperture and adaptedrto 7 receive the hot ash which falls from the gas generating chamber and thereby produces stea in from the water.
-t. A gasproducer comprising'a gas gen erating chamber of conoidal form havinga gas outlet in the top, means for introduc ng powdered carbonaceous matter into the generating chan'iber, means forintroducingprimary air and means for introducing "steam for causing gasification Within the c amber means for admitting secondary air to unite with the gas, said means comprisin refractory plates spacedly positioned aove the said gas outlet in the chamber, means for admitting the secondary air between the said plates, means provided between said plates for distributing said secondary air, means for supplying the steam to the generator from an aperture provided in the base thereof, said means including a water-containin' trough positioned below said apertureaii adapted to receive the hot ash which falls from the gas generating chamber and thereby produces steam from the water, and a screw conveyor combined with said trough, for discharging the ash therefrom.
In testimony whereof, I M51: in signature.
