Specification of Letters Patent.
Patented Sept. 1 1, 1906.
Application filed November 21, 1904. Serial 233.619.
1'0 aU whom it may concern:
Be it known thatI, FELIX L. DECARIE, a subject of the King of Great Britain, residing at Minneapolis, in the county of Ilennepin, State of Minnesota, have invented certain new and useful Improvements in Gas-Consuming Furnaces for vCrematories, of which the following is a specification. 1
This invention relates to improvements in crematories, and more'particularly to that class designed for burning the-garbage and refuse of cities and towns; and the object I have in view is to provide an aurfiliary gasconsuming furnace which may be located between the combustion-chan1ber of the crematory and the smoke-stack and through which all gases and smoke not consumed in the comlmstion-chamber of the crematory must pass, and in which they will be fully consumed, and in which any solid particles being carried along by the current of gases will be collected, thereby rendering it impossible for noxious odors or to escape through the smoke-stack.
The invention consists generally in the constructions and combinations hereinafter described, and particularly pointed out in the claims. r
In the accompanying drawings, forming part of this specification, Figure 1 is a longi tudinal section of a gas-consuming furnace embodying my invention. Fig. 2 is a detail of the preliminary gas-consuming chamber, the section being taken on line at a of Fig. 1.
In the drawings, 2 represents the casing of" the furnace, and 3 is the smoke-stack. A preliminary gas-consuming chamber 4 is located between the combustion-chamber of the crematory and thediving-ilue 5 of the furnace. This preliminary chamber is of greater area than the flue, and it is provided with a series of tile 4, that are arranged in said chamber with passages between them. The furnace is provided with the upright walls 6, 7,8, and 9, all extending upward from the bottom of the furnace, and With the depending walls 10, 11, and 12. The walls 1() and 11 are arranged opposite the walls 6 and 7. The wall 8 extends above the top of the space between the walls '7 and 10, and the wall 12 projects downward below the top of the wall 8. A tortuous passage is thus formed from the preliminary gas-consuming chamber 4 to the smoke-stack 3. Between the walls 6 and 7 I provide an ordinary fuelgrate 13, and between the Walls 10 and 11 I provide a d0wndraftgrate'14. The grate 14 may be of any suitable construction, although I prefer to use a tubular water-circulating grate. An open Water-tank 15 is located at the bottom of the diving-flue, the 1 top of the tank being preferably substantially flush with-the top of the wall 6. A similar tank 16 is located between the walls 8 and 9 and a tank 17 at the bottom of the smokestack, the tops of the tanks 16 and 17 being preferably substantially flush with the top of the wall 9. bottom of the wal 12 a transverse perforated pipe 18, that is perforated along its under surface and through which a sheet of I also prefer to provide near the water passes from said pipe to thetank 16. The operation of the apparatus is as fol lows: The tile 4 in the preliminary chamber 4 being near to the combustionchamber of the crematory are raised to a high heat by the heat from said combustion-chamber.
The vapors and gases from the material being consumed in the combustion chamber of the crcmatorywpass between these tile and the gaseous current is broken up and raised to a great heat. ing between these tile impinge upon the wall of the diving-line opposite said chamber. They are deflected by said waltand pass downward, striking the surface of the water in the tank 15. A large portionof the solid The currents of gases pass-' or unconsumed niaterial from the combustion-chamber is collected in this tank. I find that a large percentage of the material collected in this tank is combustible and after being dried it may be burned. The gases and vapors pass from the bottom of the diving-flue between the two fires upon the upper and lower grates. The flames from the fuel upon these grates pass in substantially parallel sheets through the tortuous passage over the top of the wall 8, and the gases and va ors that enter from the diving ue are held )etween these parallel sheets of 'fiames, where they are superheated and 0on surned. After passing over the wall 8 the gases take a. downward course and imiignge upon the surface of the water in the. tan and 17, and they also oass through the sheet of water above the tank 16.
By this means any remaining solid material, such as dust or cinders, is collected in the tanks 16 and 17. The space between the walls 7 and 8, which is below the line of passage of the flame from the lower grate forms a dead-air chamber, and the sheetof flame passing over this dead-air chamber creates a partial vacuum therein. Solid articles, such as cinders and dust, carried by the current of gases impinging upon thewall 8 fallback-- ward and downward and collect in this space.
This space between the walls 7 and 8 forms dust and cinders collecting chamber 8.
By employing this auxiliary gas-consum ing furnace in connection with a crema-tory, such as that shown and described in reissued Letters intent of the United States, No. 12,059, dated November 25, i902, or in Letters Patent of the United States, No. 749,269, dated January 12, 1903, of both of which I am the inventor, I find that all noxious gases and odors passing from the combustionchamber of the 'crematory are completely consumed and the gases passing from the smoke-stack are entirely odorless. I also iind that all dust andcinders and solid parl'ic cs passing from the combustion-chamber will be collected in'the water-tanks and in the chamber 8. The material can be removed trom said tanks, and that which collects at the tank in the bottom of the divingllue, which is mainlv combustible mnv be dried and burned.
l do' not limit myself to-thc details of the construction, as the same may be varied in many particulars; without departing from my invention.
l claim as my invention 1. The combination, in gas-consuming furnace, with the lower updraft-grate and Hm upper downdraft-grate spaced from each sea-9'74 other, of means for conducting gases and products of combustion between the fires upon said grates.
2. The combination, in a gasconsuming furnace, with the lower Updraft-grate and the upper downdraft-grate spaced from each other, of means for conducting gases and products of combustion between the fires upon said grates, and means for collecting the solid particles moving through said furtion.
3. The combination, in a gas-consuming furnace, with a series of walls forming a tortuous passage through said furnace,- of a lower updraft-grate and an upper downdraftgrate, said grates being located upon opposite sides of said passage, for the purpose specified. i v
4. The combination, in a gas-consuming furnace having a passage extending therethrough, of a lower updraft-grate and an upper downdraft-grate, said grates being located upon opposite sides of said passage, for the purpose set forth.
5. The combination, in a gas-consuming furnace having a passage therethrough, of the lower updraft-grate and the upper downdraft-grate arranged upon opposite sides of said passage, the wall 8 arranged opposite the spaces between said grates, and wall 7 forming with the lower part of the wall 8 and the side walls of the turnacewthe dead-air Echamber 8, for the purpose set forth.
In witness whereof I have hereunto set my hand this 2d day of November, 1904.
I FELIX L. DECARIE.
