To all 'whom 'it may concern:

Bc it known that we, ADELARD and ANTON A. YANKEE, citizens of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Gas-'Generating Apparatus, of` which the following is a specilication.

This invention relates to gas generating apparatus of that typedesigned for the production of gas from liquid hydrocarbons and which embodies generating chambers containing a mass of regenerative material adapted to be heated to the desired tempera-- ture for producing gas fromv a mixture of steam and oil passing therethrough, said chambers being constructed and connected for the passage of a blast of air in either direction, so that the regenerative material in the chambers maybe effectively heated by the combustion of steam and oil and'the traverse of the heat through the influence of the blast.

The object of the invention is to` provide a generator of the double down run type wherein the regenerative material in both generating'chambers will be heated simultaneously and both chambers may be employed simultaneously for the production of gas, thus securing an increased production with less fuel for heating npurposes and greater economy of operation by avoidance of t-he waste of heat occurring in the use of but a single generator after both have been preliminarily heated, as is customary in generators of this type.

A further object of the invention is to improve andsimplify the construction and increase the practical etliciency of gas generators of this character, as well as to pro- -vide a machine which may be readily cleaned and repaired and is not liable to get out of order.

lVith these and 'other objects in view, the invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which:-

Figure 1 is a front elevation of a gas generating apparatus constructed in accordance with our invention. Fig. 2 isa side elevation of the same Fig. 3 is a top plan view, showing one of the generators in hori- .zontal section, the section being taken D. BRAssoN '1. and. 4. 4desired points with suitably closed peep through the lower combustion chamber thereof. Fig.A 4 is a vertical section taken on the plane indicated by the irregular line 4 4 of Fig. 1. l

Referring to the drawings` A and A designate the two generators Vof the apparatus which may be of any approved construction and preferably of upright cylindrical form and consisting of a masonry wall 1 inclosed in a metal shell 2, each generator being provided at its base with a combustion charnber 3, the two combustion chambers being in permanentcommunication through a connection. 4 disposed between the lower ends of the generators, as clearly shown in Figs. The generators are provided atholes 5, and the generators and connection 4 are also provided at suitable points with manholes covered by-plates 6. The combustion chambers 3 of the two generators are 1n' communication through passages 7 with a mlXlng and discharge chamber 8 formed by the connection 4. The chamber 8 has communicating therewith a secondary blast pipe 9 provided wit-h a controlling valve 10, and has an outlet passage 11 from which leads a gas discharge pipe 12.

The discharge pipe 12 isarranged to conduct the gasto a washer 13 of any preferred construction,l which receives water through a supply pipe 14. The washer overflows through the discharge spout 15 into seal pots 16 of any approved construction, and the carbon separated from the gas passes oft' with the overflow water from the washer. The washer is provided at its bottom with a drain outlet 17 controlled by a valve 18, by which itmay be cleaned out at any time. The washed gas is drawn oit' from the washer into a suitable type of scrubber 19 through a connecting pipe 20 provided with la controlling valve 21. The scrubber is provided with a water' inlet 22 a valved drain outlet 23 and a gas discharge connection or outlet 24, through which latter the gas may be drawn off for discharge into any suitable storage reservoir.

Each generator is provided with an upper or top combustion chamber 25 with which communicates a Hue 26 adapted to be closed at its upper end by a valve 27 and provided at one side with an air blast pipe or conne tion 28 having a controlling valve 29, the connections. 28 of the two generators communicating with a common air supplyT pipe 30 through which air under pressure may be supplied from any suitable source. The chamber 25 contains a body of regenerative material 31, supported upon an arch 32 and composed of a checker work of tire brick or other suitable material. Below the arch 32 is a combined mixing and combustion chamber 33, and within the generator between said chamber 33 and the lower combustion chamber 3 is a mass of regenerative material 34, also preferably composed of a checker work of tire brick, supported by an arch forming the top of said lower combustion chamber.

Surrounding the upper portion of each generator are two sets of steam and oil pipes-one set designed for heating and the other for gas producing purposes. One of these sets comprises a steam pipe 35 and oil pipe 36 which are connected by suitable branches 37 with injector nozzles 38 entering the combined mixing and combustion chamber 33. The other set of pipes comprises a steam supply pipe 39 and an oil pipe 40 connected by branches 4l with nozzles or ejector burners 42 which enter the chamber 33. Surrounding the base of the apparatus, that is extending completely around both generators are main steam and

oil supply pipes

43 and 44 which are adapted to be respectively coupled to conductors leading from the sources of steam and oil supply at the

points

45 and 46. Branches 47 connect said

pipes

43 and 44 with injector burners or nozzles 48 which enter the lo-wer combustion chambers 3 of the generator. Between the said

connections

45 and 46 and the branches 47 leading to the nozzles 48 each side of the apparatus the pipes are provided respectively with controlling

valves

49 and 50. From the pipe 43 extends a pipe 51 which is coupled to the steam pipes 39 of the two generators and is provided with a controlling valve 51. Leading from the pipe 43 on opposite sides of the pipe 51 are

pipes

52 and 53 respectively which independently connect the pipe 43 with the steam pipe 35 of the two generators and are provided respectively with controlling

valves

52 and 53.

Pipes

54 and 55 connect the oil pipe 44 with the oil pipes 36 of the respective generators and are provided with control ling valves 544 and 55, while pipes 56 and 57connect the pipe 44 with the pipes 40 and nozzles 42 of the respective generators and are provided with 'controlling

valves

56 and 57. It will be observed that all of the valves controlling the tlowmf oil, steam and air are arranged at the front of the machine in a position for convenient i'nanipulation, so that the entire operation of the machine may be governed from a single point.

In order to supply suilicient oil and steam for the generation of a maximum amount of gas at a determined pressure within a gi ven amount of time, the injectors 43 should be made comparatively large. At the same time if these injectors were employed for the initial h eating,which requires but a relatively small amount of oil and steam, a waste of oil and steam would result, as too much oil and steam would be supplied. lVe, therefore, employ the injectors 38 in addition to the injectors 43 and malte them preferably of relatively smaller size, so that said set 38 may be employed solely for initial heating and to supply only a suilicient amount of oil and steam for the purpose.

In operation, "assuming all valves to be closed, the valve 27 of generator A and valve 29 connected with the air blast 28 o't the generator A is opened, after which the

valves

53 and 55 are opened, to .inject steam and oil through the nozzles 38 into the combined'mixing and combustion chamber 33 ofthe generator A. The charges being ignited, said chamber' will be heated, as will the arch 32 and regenerative material 31, hea-ting t-he blast as 1t passes downward therethrough, which blast will in turn heat the regenerative material 34.y As ysoon as the heat begins to pass from generator A to generator A through the chamber 8 of connection 4, valve 10 is opened to augment the blast and

valves

49 and 50 are opened for the injection of steam and oil into combustion chamber 3 of generator A', the mixture being ignited and further @eating the blast which, on its upward travel through generator A, heats the bodies of regenerative material therein and finally discharges through the outlet 26 of said generator. The steam valves are open at the times named to admit steam with the oil when the generators are clean or free from carbon deposits. If, however, the generators are coated with deposits of this character, a restricted amount of oil may be admitted with the air and allowed to burn to partially or wholly consume the carbon before the full supply of oil and steam are admitted. After the bodies of regenerative material in the two generators have been brought to a proper temperature,

valves

10, 27, 49, 50, 53,'

55 and 29 are closed and valve 21 is opened, after which valves 57 51 andV 56 are opened, thus injecting steam and oil through nozzles 42 into the combined mixing and combustion chambers of both generators. The mixture is vaporized in these chambers and rariied and heated on its down fiow through the regenerative bodies, insuring the production of gas containing a proper percentage of oil, and then the currents of gas discharge into the connection 4 and through pipe 12 into the washer, thence to the scrubber and finally to the storage reservoir pipe 12 into the washer. from thence to the scrubber and finally to the storage reservoir.

lVhen the regenerative materials in the generators have become soreduced in temperature that gas can not be economically produced, that is, when the temperature is so low that the gas would be too rich, the opened valves above mentioned are closed and the generators again heated in the manner previously described, exceptin the reverse way, the generator A being employed as the heating generator, the air being drawn in through the stack 26 of said generator, while the products of combustion discharge through the correspondin stack of the generator A. After the bodies of regenerative material have been heated sutticiently for the second run, the producing operation is again carried out in the manner hereinbefore described and. which will be obvious from' the `foregoing description.

It will be observed that in the operation ofl the apparatus both generators are simultaneously utilized for generating gas, and both simultaneously heated for the subsequent operation, and that as a consequence greater eiiciencyis secured, as well as an increase of product, over generators of that type in which after both generators are heated but one is employed for producing, allowing the heat within the other to go to waste.
