PROCESS ANU APPARATUS FOR THE PRODUCTION OF USEFUL FUEL GAS Filed May 20, 1940 Patented' Nov. 17, u1942 y UNITED 'STATES PATENT OFFICE 2,302,156 PRooEss AND APPARATUS Fon THE rao- DUCTION F USEFUL FUEL GAS Friedrich Totzekf Essen, Germany, assignor, by mesne assignments, to Kappersv Company, Pittsburgh, Pa., a corporation of Delaware ApplicatiouMay 20, l1940, Serial In Germany May 27, 1939 9 Claims. (Cl. 48-74) This invention relates to the production of fuel gas of high heating power out of dusty or finely granular fuels, such as black or browncoal, or coke or semi-coke made therefrom, the fuel being converted at a high temperature with air (oxygen), steam and carbon dioxide, where by a gas is produced which is rich in hydrogen and carbon monoxide.
It is possible to produce a fuel gas of high calorific valuein such a manner that part of the lo finely reduced fuel is burnt in a coal dust firing chamber and the hot gases produced are brought into contact with the other part of the reduced fuel, the mixture then being passed continuously, preferably in circular current, through a cylindrical reaction chambe steam being added to the mixture of fuel dust and hot combustion gases leaving the coal dust nring chamber.
The present invention has for its principal obp ject to produce a high grade fuel gas out of dusty or finely granular fuels in such a manner that part of the produced fuel gas, preferably after a suitable preheating, is burnt with oxygen (air) and the combustion gases of high temperature thus produced are mixed with the fuel dust, whereupon the mixture is treated with steam.
Contrary to a former method, this invention enables a considerable simplification of the gas production in that a special coal dust burner together with the requisite comparatively complicated auxiliary contrivances ar dispensed with and replaced by a gas-air burner which is a simple means from a constructional and operating point of view.
v Another advantageof the present invention is that the production of hot combustion gases of a certain uniform high temperature may be carried out in a considerably simpler way by the combustion of fuel gas than is the case with the combustion of fuel dust. Thus the temperature of the hot gases mixed with the fuel dust may be raised approximately up to that point which is limited by the durability of the building material necessary forthe construction of the reaction chamber.
A further characteristic feature of my invention is that the hot mixture of gas and fuel dust is brought into contact with a highly heated mixture consisting of steam-'and combustion gases which is obtained vby the combustion of 5," fuel gas, preferably by burning part of the fuel gas produced and by mixing the hot combustion gases with steam, if possible with superheated steam. The combustiongases contained in the steam-gas mixture preferably serve as a heat car- 55 VWater gas with a high calorifie forth and understood, I now Fig. 2 is a horizontal section" on line II-II of Fig. 1.
Referring to the drawing, a gas producer is v illustrated which has a gas reaction chamber I Vhaving substantially the shape of a horizontal cylinder formed-by refractory brickwork 2 placed in a metal jacket 3. At one axial end of the gas reaction chamber flamed gas-air burner 4 which terminates substantially tangentially` into the gas producer chamber I, as may be seen from Fig. l. In front of the burner 4, in the Wall 2 of the gas reaction chamber I as a mixing box, into which terminates the slotlike fuel dust supply 6. The fuel dust to be gas-v ied is filled into the delivery slot Ii in a well distributed manner and meets the hot combustion gases Within themixing box 5, said combustion gases escaping from the burner 4 at high velocity. 'Ihe fuel dust is finely distributed by the hot combustion gases and in this form it is delivl ered tangentially into the gas producer chamber I. The mixture of fuel dust and gas moves through the gas reaction chamber I in a spiral-y like current. The effective or useful gas produced is withdrawn axially from the gasifying chamber I through the opening I at the axial end of the producer -opposite the end at which the burner 4 is arranged.
A series of ring-like provided in the bricklining 2 of the gas producer chamber I. These channels are connected in pairs or in groups with the main-distributing ducts 9, I0 as may be seen from Figure 2. Furthermore the ring-like distributing channels 8 arefcoupled with the gas producer chamber by means of nozzle-like apertures II. I
The apertures II are carried out in such a manner that they terminate nearly tangentially into the gas reaction chamber I. The media introduced through the apertures II into the gas producer chamber I therefore assist the circular movement of the fuel dust through the gas reaction chamber I and preventvthe dust` from be- I there is arranged a multiple there is provided a recess 5 servingv distributing channels 8 is 2 ing deposited in large layers upon the bottom of the gas reaction chamber I. Moreover, the apertures are inclined in the direction of the longitudinal axis of the gas reaction chamber I. The spiral-like movement of the fuel dust as mentioned above, is due to this construction. The fuel dust therefore moves from the mixing box arranged at the one end of the gas producer chamber gradually in a spiral-like current to the gas exit 1 'situated at the opposite front side of the gas reaction chamber I.
Beside the gas producer I there are arranged two steam superheaters I2, I3 which are connected by means of the channels I3, I5 with the main distributing ducts 9 and I0 respectively. Each steam superheater I2, I3 is equipped with a gas-air burner i6 which serves for the production of hot combustion gases of high temperature. Steam is introduced from above through the opening I1 (see Fig. 1) into the superheaters I2, I3 where the steam is intimately mixed with the hot waste gases of the gas-airburner I6. The highly-heated mixture of gas and steam then flows through the channels ifi, I5, the main distributing ducts 9, lll and the ring-like distributing channels 8 to the apertures II through which it passes tangentially into the gas producer chamber I at high velocity.
The fuel dust residue depositing on the bottom of the gas reaction chamber I gradually reaches the ash-outlet IB lying at the useful-gas exit end of the chamber I, due to the spiral-like motion of the gasifying media. The ring-like channels 8 are likewise equipped with special ash-outlets I9 through which the residue may be discharged which latter has passed through the aperture II and accumulated in the channels 8.
The fuel gas supplied to the burner fi and to the burner I6 is taken from the useful-gas stream preferably after the useful-gas has been dedusted. Part of the useful-gas produced is in continuous circulation through the gas producer. The caloric value of the gas is advantageously improved if the conversion of thefuel dustwith fuel gas and steam takes place at a low velocity only. f
As may be seen from Fig. 1, steam is introduced into the gas reaction chamber I even at that part of the reaction chamber wall lying directly opposite the burner il. .This part of the chamber wall is exposed to very high temperatures due to the combustion of gas and air within the burner d. On account of the fact that steam is introduced from this part of the wall into the gas reaction chamber, a very rapid reaction is caused there with the fuel dust whereby the temperature is reduced to such an extent that the refractory building material may not be superheated at this point, as endothermic conversions are carried into eiect. The separation of the ring-like channel series 8 into two groups to be operated independently from each other, as illustrated on the drawing, or into several groups offers the advantage that it is possible to run the various zones of the gas producer I with hot gas-steam mixtures of different composition. Thereby it is possible to maintain the most favourable efficiency in any zone of the gas producer I without having to fear that dangerous superheatings occur at any point.
The nozzle-like openings in the wall of the gas producer through which steam and hot combustion gases may be\introduced are suitably placed at such a distance from one another and 75 constructed in such a way that no dead spaces are formed between the nozzles in which fuel dust or ash may precipitate. The stream of gasifying media passing along the wall therefore prevents the ash from depositing and sticking onto the walls. Furthermore it is of advantage to arrange the nozzle-like openings along the wall of the gas producer chamber in a tesselated way e. g. like checker-work apertures, thus counteracting the formation of undesired dead spaces to a greater extent.
I have now above described my present invention on the lines of a preferred embodiment thereof but my invention is not limited in all its aspectsto the mode of carrying it out as described and shown, since the invention may be variously embodied within the scope of the following claims.
