. GAS-PRODUCER.

Specification 01' Letters Patent. nulication tiled July 24, 1398. Serial No. 445,071.

To all whom it may concern:

Be it known that I, Janns'A. Hnamcrz, a

citizen of the United States, residing in the city of New York, county of New York, 5 and State of New York, have invented certain niprovemcnts in Gas-Producers.

This invention contemplates improvemepts in the manufacture of gas by means of a duplex gas producer having; a regenera- Tt 1s designed to make coke in one producer while the usually waste gases given off during this operation are carried down, enrichcd,- purified and made permameat in the other properly coked producer,the operation being reversed when it becomes esirable to feed fresh fuel, which is charged into the producer previously effecting the secondary operation. To carry out this operation in the most efficient and economical manner, I have devised a structure having characteristic features which will fully appear in the following description and the accompanying drawings in illustration thereof.

In the drawings, Figure 1 is a sectional elevation of a continuous duplex producer designed for the practice of my invention; Fig. 2 is a transverse sectional view takcn on the line 2-2 of Fig. 1, and Fig. 3 is an irregular vertical sectional view approximately on the line 3--3 of Fig. 2.

I As illustrated in the drawings, the prc V ferred forlnof the producer compriscs the base A having the two cones A. surroumlcd by the circular basins A. which arc divided by the centraliridgc A. the ridge being lower thandhmgeneral level of the base so that" there is communication between the basins. 'Iillars A formed in the base below the general level thereof, support the 4 producer bodies B centrally above the respective cones A. channels A being formed in the base so as to communicate with the basins to receive water therefrom and seal 45 the joints at the bottoms ofthe bodies.

Within the bottom or ash hopper of each body'are the'twye'rs comprising the boxes C radiatingfrom the termihus of a blast piped). The terminus of each pipe I) is centrally disposed with reference to the cor- "responding body and f'discharges intogthe boxes. which" latterdischarge connected wlth opposite sides of a, valve box Patcnted July 25, 1911;

E and in communication with this valve box are the blower F and -the'gas take off pipe G, thelatt'er delivering to a scrubber (i and the flow bein facilitated by a suction blower G. B ower F and suction blower G are approximately balanced, that is, the suction blower is of a capacity such that the quantity of as 'withdrawnfroni the producers will car a direct relation to the amount of blast forced therein by the blower F.

A simple form of valve, as the butterfly valve- H, is located' within the box and operated through an arm H connected therewith and with a hand operated rod H, the valve being designed to place the blower in direct communication with either of the pipes Dand at the same time establish communication between the other of these pipes and the gas take off pipe (in The valve box is provided with hollow walls forming chambers E containing water for cooling purposes. 7

To How water over the twyers and cool them, the boxes 0 have formed in their ridges the notched channels C. and the conical top of the vertical. part I) of the pipe D,

which joins these boxes, is provided with the channel I) which communicates with the channels CH Perforated pipes C lie in the channels C and through the walls of the'bodies from the circular pi pes C" exterior to the bodies. the pipcsC being connected by branches C with a valve box (l -containing a valve C by which water maybe directed into either or both sets of pipes;

A passage Ivconnects the-upper parts of the producers and in this passage is located the double expanding tube or nozzles J (analogous to a ,Venturi tube in the form extend inwardly illustrated) having mouths communicating with'the'respective producer bodies. In the contracted throat J of this tube are dis posed the outlets or nozzles K of tubes K .which are connected with the valve box L. This box contains'a butterfly valve M, connected by anarm M with the rod H'uand has communicating therewith a pipe N for the intr'oductionof fluid hydro-carbon and steam, so. thatwhen the valve H is setto induce flow of gas from say the left hand to the right hand producer, the valve M .15 set 'to'induce the flow of steam and fluid hydro-carbon into the right hand pr )(lLlCGI' to accelerate the action and enrich ti e gas.

-The accelerator serves not only to facilitate containing a valve N, with a steam pipe 0,

which leads to the blower-F and contains a valve 0 between the blower and the branch N. The pipe N is also connected with a branch N containing a valve N which controls the flow from a funnel N communieating with the branch, oil being dropped into the funnel from a pipe P.

A urge pipe Q, is provided with the brunt: es Q, which communicate with the respective producers near the tops thereof, the pipe having the test cock Q, and the removab e top Q.

Hoppers R, connected with the tops of the respective producers, provide meansfor charging them with fuel.

In operation, coarse clean ashes are filled into both producer bodies so as to entirely surround and cover the twyer structure. Wood and coke are then placed on the ash beds and i nited; the reversing valves being asm-ea to provide draft and set vertical so as to "fe d until beds of hot co ermit air to draw throu h bot, pipes D rom the now fully open lower- F and the purge pipeQ being ermit the escap'e? of sirioke therethrough. Vhen the fires in the respective reducers have been e are provided, the sealing basins are filled with water to the proper level to immerse the bottoms of the odi'es, steam blast is gradually added, and soft-coal and cokc are fed to the fires until, the gas evolved will burn with the production of a. flame. The top of the purge pipe isthen closed, the reversing valves are thrown so as to carry on the initial production of as in the producer desired, and the raw gas 1s carried into the second producer and downwardly through the bed of hot coke in the bottom thereof, issuing through the twyers and the corres onding pipe D to the as take-ofl" ipe G. 'Ihns the rawgas fron t e first producer is subjected in the second producer to a treatment which gasifies the tarry nia-tter carried therewith, breaks up excessive CO, with the formation .of CO, enriches the gas .with production of large increments of hydrogen gas, making semiwater gas, and delivers it in su rior condition, with less work to be done in the scrubber and with less disposition to clo the action of an engine in which it ma 'e used. After this operation has been carried on until the hot coke in the producer effecting the secondazhy operation has become partly cooled, e reversing valves are thrown and fuel is fed into the producer, which by the reversal of the valves becomes the nrimary producer, from whicl he gas evolved is carried through the coh-v bed of the adjacent producer to the gas lake-off pipe G.,

It is to be understood that fuel is always fed into the producer used as a primary producer so that when it becomes secondary by the reversal of the operation, it will contain a bed of hot coke, which acts upon the raw gases delivered thereto from the opposite producer. Hence any tar that has not reviously been decomposed and changed into permanent gas, as also the soot carried therewith, is intercepted. Any tarry matter of value which lodges in the coke bed and is not gasificd by reason of the lack of free oxygen, is changed into gas upon the reversal of the operation an' the introduction of oxygen. This mode of o aerationavoids the necessity of purging o and making up fresh coke fires in the usual manner. It provides means for making a high grade and clean semi-water gas with an inferior quality of fuel. lVater gas can be made directly as distinguished from former operations. There is little leakage or undesirable introduction of air because the operation is carried on by combined pressure and suction which are approximately balanced.
