GAS-GENERATOR.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Original application filed April 22, 1912, Serial No. 692,525. Divided and this application filed April 1,

1914. Serial No. 828,782.

To all whom it may concern Be it known that I, GUSTAV P. LUEDKE, a citizen of the United States, residing at Chatham, in the county of Sangamon and I State of Illinois, have invented a new and useful Gas-Generator, of which the following is a specification.

The present invention relates to improvements in gas generators, the present application being a division of my application filed April 22, 1912, Serial'No. 692,525 for an apparatus for condensing gases from noxious fumes and utilizing the heat thereof, one object of the present invention being the provision of a gas generator adapted to be disposed to be effected by the fumes in transit, and at the same time provide a compartment by means of which the fumes are condensed and the condensation is precipitated in the compartment at the lower portion thereof where the same may be collected and removed, such precipitant in the fumes from smelters being principally arsenic trioxid and zinc oxid.

A still further object of the present invention is the provision of a gas generator,

especially adapted for generating gas from coke, soft coal or other carbonaceous material, the said gas to be used in connection with the formation of hydrogen gas and carbon monoxid gas, there being means provided for introducing air and steam to the lower end of the retort and into the carbonaceous material for assisting in the formation of such gases.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a perspective view of the complete apparatus, portions being broken away to show the interior structure thereof. Fig. 2 is a central transverse cross section therethrough.

Referring to the drawings, the numeral 1 designates the brick foundation or chamber which is provided withthe grating 2 thereacross to form the lower precipitant receiving chamber 3 having the clean out doors 4. The sheet metal casing 5 which is disposed above the brick foundation, has an enlarged central portion and the two oppositely disposed inlet and outlet flue ends 6 and 16 respectively, the flue 6 being adapted to be connected directly to the flue of a smelter or reverberatory furnace, so that the greatest possible heat from the fumes may be utilized in the present apparatus, while the outlet flue 16 is adapted to be connected in communication with the respective fines of the boiler construction as illustrated in the above mentioned application and in my copenfliing application filed of even date herewit A lower chamber or flue 7 is provided while dis osed at each side of the retort 19 are the ues 8, each one of which is provided with the hinged sectional bottom 17, by means of whichthe flue area may be increased or vdecreased, and also by means of which the condensate from the fumes may be properly precipitated upon the grate 2' Controlling the inlet end of the upper flues 8 are the vertically depending swinging doors 13 controlled by the cranks 14. By this means the fumes are properly directed to any portion of thegas retort 19 according to the amount of heat necessary.

As before stated, the retort 19 is disposed to receive carbonaceous material such 'as charcoal or coke, while in order to supply the necessary hydrogen and oxygen thereto, to assist in the formation of hydrogen and carbon monoxid gas, the air directing pipe 20 and the steam directing pipe 21 are projected from below and are in communication with the lower end of the retort 19, the gases formed therein being carried off through the outlet 23, to any desired apparatus, or as particularly stated in the before mentioned co-pending application of which this application is a division.

By this form of apparatus, it is evident fumes, coming from the smelter or reserberatory furnace, may beproperly supplied and furnished, utilizing the heat from such fumes during its passage through'the apparatus heretofore mentioned.

It is evident that an alternate blowing ef steam and air into the 'hot retort 19 containing a hot bed of incandescent coal or coke, Water gas, producer gas or coal gas can be produced respectively.

What is claimed is: I

1; A gas generator, including a casing having a grate extending parallel to the bottom to provide a precipitant chamber therebelow, a flue leading in at one end above the grate, a second flue leadingfrom the casing at the opposite end, the portion of the casing between the flues being divided into a plurality of longitudinal flues, a damper at the inlet end of each longitudinal flue, and a gas retort disposed to have a certain portion of its exterior exposed in said longitudinal flues.

2. A gas generator, including a casing having a grate extending parallel to the bottom to provide a precipitant chamber therebelow, a flue leading in at one end above the grate, a second flue leading from the casing at the opposite end, the portion of the casing between the flues being divided into a plurality of longitudinal flues, a damper at the inlet end of each longitudinal flue, and a gas retort disposed to have a certain portion of its exterior exposed-in sai'd'longitudinal flues, the bottoms of the longitudinal flues being hinged to permit the emptying of any precipitant therefrom.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
