Claims.

This invention particularly relates to improvements in the Well-known methods of manufacturing carbureted water gas in a gas-making set including a generator, a carbureter, a superheater, and a seal, -all connected in a well-known manner, and equipped with the usal fixtures such as pipes and valves for supplying suitable media for blasting a fuel bed in the generator, and for making up and down gas-making runs through the fuel bed, and for carbureting the water gas so made. My invention particularly relates to improvements in such processes in which the carburetion is effected by the use of heavy oil, such as bunker oil, and in which a down blasting is ef- A fected by admitting the blasting air at the top of the carbureter.

Also, preferably, the steam for the down run is admitted at the top of the generator, but it is within the spirit of my invention to admit such steam for the down or reverse run at the top of the superheater, and then pass the steam downwardly through the superheater and upwardly through the carbureter and thence to the top of the generator, for operation under the wellknown back-run process of making carbureted Water gas.

The invention is particularly applicable for working in that type of a carbureted water gas set in which the hot gas valves for controlling the direction of ow are located adjacent the seal, i. e., the setting of these valves determines through which one, of two pipes communicating with the seal, the gas flow should take place.

The annexed drawing and the following description set forth in detail certain steps illustrating my improved process, these steps constituting, however, but a few of the various series of steps by which the improved process may be carried out.

The gure is a view, partly in elevation and partly in vertical section, of apparatus for manufacturing carbureted water gas by the use of my improved method.

Referring to the annexed drawing, a generator A, a carbureter B and a superheater C constituting carbureting apparatus, and a seal D are con'- nected together in the well-known manner by a pipe E .between the top of the generator and the top of the carbureter, a pipe F between the bottoms of the carbureter and superheater, a pipe G leading from the stack C of the superheater C to the seal D, and a by-pass pipe H from the bottim of the generator to the pipe G. Pipe I controlled by valve I' feeds air into the bottom of 55 the generator A, and pipes 2 and Il controlled by valves 2' and Il', respectively, feed air into the top of the carbureter B. Steam pipes 4 and 8 controlled by valves 4' and 8', respectively, feed into the air pipe l and the top of the generator A, respectively. An alternate steam pipe 9 controlled by valve 9 feeds into the pipe G. A pipe 5 controlled by valve 5' feeds heavy oil into the top of the generator A. The pipe G is controlled by an up-run hot gas valve 1 and the pipe H by a down-run hot gas valve 6. The superheater stack C' is controlled by a valve 3 'and an additional stack I0 is provided which communicates with the pipe H and is controlled by a valve I0". The dip of the pipe G into the seal D is in an amount suiicient to exceed the effect of the pressure in the stack C'.

The manner of using the afore-described apparatus, when working my improved process, consists in rst preparing for forward or upward blasting by having all valves closed except thel stack valve 3 and the up-run hot gas valve 1. Then the fuel bed in the generator A is blasted with air which is admitted by opening the valve I', and the resultant blast gases which pass through the connection E from the generator A to the carbureter B are burned by air admitted by opening the blastl valve 2', this burning of the blast gases suitably heating the checkerwork in the carbureter B and superheater C. The resultant products are discharged through the open valve 3 of the stack C.

Then the carbureter blast valve 2' is closed and, in sucession, the generator blast valve I and the superheater stack valve 3 are also closed, which places the apparatus in condition for an up-run. 35

This up-run is effected by first opening the steam valve 4' which effects the formation of the blue water gas by the passage of the steam y through the heated fuel bed, which blue water gas is carbureted by heavy oil admitted by open- 40 ing the valve 5', the heavy oil being sprayed upon the fuel bed and being cracked and volatilized and mixing with the blue .water gas issuing from the fuel bed and being permanently fixed in the heated checker-brick of the carbureter B and 4 superheater C. As has been stated, the hot gas valve 1 in the pipe G is open so that the resultant gases pass into the seal D through the pipe G. The up-run is terminated by rst closing the oil valve I' and then the up-run steam valve 4'.

Then a down-run is effected by first opening the down-run lhot gas valve 6, then closing the up-run hot gas valve 1, and then opening the down-run steam valve I', which results in the 55' formation of blue water. gas by the passage of steam downwardly through the fuel bed, which blue water gas issues from the bottom of the generator and passes by pipe H into pipe G and thence into the seal D. The down-run is ternunated by closing the steam valve B'.

. Then a down-blow is effeted by first opening the valve I' of the auxiliary stack I0, and thenl opening the. blast valve II at the top of the carbureter B, which effects a down-blow through the fuel bed of the generator A, and the resultant products therefrom pass into the pipe H and thence into stack I0 and out through thestack valve I0. The down-blow is terminated by closing the blast valve I I'. Then the up-run hot gas valve 1 is opened, the down-run gas valve 6 closed, the superheater stack valve 3 opened, and the stack valve l0 closed. Then the apparatus is in the same condition as was originally presented for forward blasting, and a cycle has been completed.

Under some conditions when working the-improved process which has just been described, it

may be deemed essential toeifect a short blowblue water gas during the up-run; in which case,

the oil valve 5', instead of being closed at the termination of the up-run, can be allowed to remain open during part of the down-run, and then this oil valve 5' can be closed at any desired time after openingthe down-run steam valve-8'.

Under some conditions, it may be desired to make a short down-blow run; in which case, the top generator blast valve I I', which furnishes the air for the blast downwardly through the fuel bed, may be opened, after the termination of the down steam run, and before the opening of the auxiliary stack valve I0', and thus the down-blow gases pass through the connections H and G to the seal D for a short period, and then the auxiliary stack valve l0' is opened.

As before stated, it is within the spirit of my invention to admit steam for the down or reverse run at the top of the superheater C through the pipe 9, instead of to the top of the generator A through the pipe 8, if it is desired to operate the gas-making set under the well-known back-run processof making carbureted water gas. In this event, the steam passes'from the pipe 9 through the connection G and thence into the superheater C and carbureter B in succession, whence it passes through the pipe- E into the top of the generator A and downwardly through the fuel bed in the operating manner before described with reference to the ordinary admission of steam through the pipe 8 to the top of the generator A.
