Patentedsept. 17, 1912.

Application filed February 14, 1910. Serial No. 543,721.

To all whomtt may concern:

Be it known that T, Jones H. Him, a

citizen of the United States residing at El Paso, in the county of E1 fPaso and State of Texas, have invented a certain new and useful Improvement in Gas-Producers, of,

which the following is a specification.

This invention relates to improvements in apparatus for making producer gas.

The object of the invention is to provide a producer for making gas from the combustion of a continuous stream of gas-forming combustible material mixed with airand the subsequent combination of gases formed by the decomposition of steam or other endothermic agent and recomposition of the resulting gases with the gases evolved by the said combustion. I

Another object of the invention is to so construct the producer that the producer gas made therein will be high in percentage of carbon monoxid and methane or marsh gas, and low in percentage of carbon dioxid.

The accompanying drawing illustrates one embodiment of the invention and from a study of the same as described" in the specification, a clear conception of the invention may be had.

In the drawing-Figure 1 is a central,

vertical section of a gas producer. is a section of the producer taken line 'IIII of Fig. 1.

Referring to the drawing, the outer shell Fig. 2 on the 4 is preferably circular and has ahollow column 5 disposed centrally therein. This column 5 is built up from the floor of the producer to a point slightly short of the top of the shell where it enters a recess 40 formed in the topof the shell 4. This construction provides for a variation in the relative expansion of the shell 4 and the column 5. The column 5 is pierced near its upper end by a large number of ports 11. These ports 11 form a means of communication between the interior of the shell 4 and the interior of the hollow column 5'. The interior of the shell 4 forms a gas generating chamber which is divided into lower chamber 2 and upper chamber 10, by means of an annular ledge 91 projecting inwardly from the shell 4 before leaving annular communicating passage 9 between the ledge 91 and the ,outside of column 5, and this passage 9 constitutes a centrally disposed passage through which said column extends.

chamber 2. ,lower end of shell 4 at the lowest point of the inclined floor of chamber 2. A cleaning take of A tangentially disposed inlet 1 for gasformmg combustible material mixed with air is formed in the shell 4 near the bottom 7 of chamber 2. Other valve controlled inlets 13, tangentially or otherwise disposed, are

passed throu h the shell 4 near the top of K radial slag port 8 pierces the port 7 pierces the shell 4 so as to-communicate with the lowest part of the interior 3 of hollow column5. This cleaning ort 7 is exteriorly provided with a cover. n ofi shell 4 is centrally provided at its top with a port l2 having an exterior cover and com- .IllIlIlICfitll'lg with the extreme upper portion of the interior 3 of hollow column 5.

Operation: Finely divided gas-forming combustible material such as coal-dust or atomized oil is introduced under pressure to inlet 1 into combustion chamber 2, sufficient air to produce completecombustion being supplied until a high-temperature is attamed in said chamber, ignition having been initially caused. The volume of air admit-ted is then decreased in such degree that carbon dioxidceases to be produced, and the resultant gas is carbon monoxid at a temperature of incandescence.- The highest temperature is attained in the upper part of the combustion chamber 2, and the gases and material. swirl about column 5 within said chamber, and "the resultant gas or gases'pass through annular passage 9, and, swirling about column 5 in chamber 10, thence pass through ports'll, thence pass downwardly through mterior 3 of column 5, and out through-otf-take pipe 6 to any point desired for storage or use. This use of the producer in passing the gas downwardly through column 5 is where the producer is designed to more permanently fix the gas produced, as the fixing will take place while passing downwardly through the highly heated column 5. If such a use is not de-- sired by the producer and the gas is to be immediately urned in a furnace, ,for instance, the gas may be passed directly through said furnace through t-he port 12, which is in that case suitably connected thereto. is admitted through inlets 13 to the upper part of chamber 2, increases the swirllng pipe 6 connects with the lowest point a the interi0r3 of hollow column 5. The,

Steam or other endothermic agentbe removed from the action of the combustible material and gases about column 2, if these inlets are tangen-' tially arranged, and at the high temperature decomposes in-the presence of the highly heated carbon, forming hydrogen, carbon monoxid, and methane or marsh gas. The formation of the marsh gas is made possible orits decomposition prevented, by the introduction of the steam or other form of moisture, undoubtedly due to the reduction of the temperature by its introduction. The reduction of temperature of course serves to preserve the Walls of thefurnace from destruction by the high temperatures attained.

The central location of the annular passage 9, as compared with the major portion of the combustion chamber 2, together with the swirling of the combustible material and gases in the combustion chamber 2, prevent the passage of solid materials from the combustion chamber, (but this. feature is not broadly claimed herein as it is claimed in application S. N 465,424, filed Nov. 30, 1908), and an excess of such solid material, and also the used impurities and ash, may exterior and pass through the sla port 8. Any solid material that may possi 1y blow through ports 1] and pass downwardly through the interior 3 of column 5, will be deposited at the lowest point of said interior 3, and may be removed from the exterior by passing through cleaning port 7. I V

- umn joining It should be understood that it is not desired to be limited to the exact details of construction shown and described, for ObVlr ous modifications will occur to a person skilled in the art.v

It is claimed and desired to secure by Letters Patent,+

1. The combination in a gas producer, of a shell having an inner recess in the to thereof, a hollow colunm within said shel extending from bottom to top thereof and into said recess permitting movement within said recess said column being pierced by ports near one end, the whole forming an annular vertically disposed gas generating chamber, an inlet to said chamber and an ofitake pipe connecting therewith through said column and ports.

2. The combination inea gas producer, of a shell, a hollowcolumnwithin said shell forming a gas generating chamber, said colwith the shell at top and bottom but constructed to allow for any expansion and contraction relatively thereto due to heating and cooling, ports through said column, an inlet to said chamber an an off-take pipe leading from said column.

In testimony whereof, I aflix my signature in the presence of two witnesses.
