COMBUSTION-CHAMBER FOR SULFUR-BURNERS.

Specification of Letters Patent. Patented June 21 1921 Application filed April 20, 1920. Serial No.. 375,391.

T 0 all whom it may concern:

Be it known that I, F RED B. CHAPPELL, a citizen of the United States of America, and resident of the city of Glens Falls, in the State of New York and United States of America, have invented certain new and useful Improvements in Combustion-Chambers for Sulfur-Burners, of which the following is a full, clear and exact description.

This invention relates to improvements in combustion chambers for sulfur burners, and the object is to provide a combustion chamber in which air is very thoroughly mixed with sulfur vapor, thus avoiding sublimation.

A further object is to provide a combustion chamber permitting the use of greater draft than heretofore, thereby increasing the capacity of the apparatus proportionately to its size.

The device consists briefly of a metal tank, preferably cylindrical, lined with refractory material and containing a baffle wall. A vapor inlet is provided axially out of normal with the baffle wall and a vapor outlet is provided on the opposite side of the baffle wall.

In the drawings which illustrate the invention:

Figure 1 is a plan view of the device, illustrating its relation to other parts of the apparatus.

Fig. 2 is a partial sectional view on the line 2-2, Fig. 1.

Fig. 3 is a partial sectional view on the line 3-3, Fig. 1.

Referring more particularly to the drawings, 11 designates the combustion chamber of a sulfur burning apparatus, in which the sulfur is burned, provided with an antisublimation or ventilating sleeve 12, and 13 designates a combustion chamber, forming the subject matter of this invention, provided with an inlet sleeve 14 alined with the sleeve 12 and with an outlet sleeve 15 located at any suitable angle to the inlet sleeve but preferably at an angle of 135 thereto.

The combustion chamber 13 comprises a metal shell 16, preferably 0 lindrical, containing a complete lining 1 of refractory material, such as fire brick. Thelining is spaced at the sides and top from the shell and the space filled with asbestos or other insulating material 18. A bailie wall 19 is provided in thechamber extending diametrically from side to side and from top to bottom. This wall is preferably constructed of refractorymaterial such as a good quality of fire brick. The upper part of the wall is built in the manner known as checker-work thus leaving apertures 20 through the wall for the passage of vapor from side to side thereof- It will be noted that these apertures are considerably above the inlet and also that the wall is disposed out of normal to the axis of the inlet sleeve and preferably at an angle of 45 thereto. Any suitable clean-outs 21 may be provided on each side of the wall 19.

The operation of the deviceis as follows Sulfur is burned in the device 11 and the vapor flows through the sleeves 12 and 14: into the combustion chamber 13. Air is mixed with the vapor during its passage through the sleeve 12. The mixture of burning sulfur vapor and air impinges on the wall 19 at an angle so that it is deflected against the curved surface of the chamber wall and thus acquires a swirling movement which insures thorough mixing of the vapor and air. The mixture is drawn by the draft upwardly and through the openings 20 which break up the vapor into small streams, thus further perfecting the mixing with air. The gas then flows down and out through the sleeve 15 to agas conduit. The swirling motion imparted to the vapor and air and the breaking of the same up into numerous small streams so thoroughly mixes the air and vapor that combustion is complete and sublimation entirely avoided even under heavy draft. The combustion occurs largely on the inlet side of the wall and in any case is completely above the outlet so that no flame passes through the outlet 15 into the gas conduit. The chamber being constructed of fire brick and insulated very little of the heat generated is lost by radiation.

While the device has been illustrated as circular it will be understood that the invention is not limited to this particular form nor to the particular angle between the inlet and the baffle wall.

Having thus described my invention, what I claim is 1. A combustion chamber for sulfur burners comprising-an inclosing wall, inlet and outlet passages, and a bafile wall arranged out of normal to the inlet passage to impart a swirling motion to the incoming stream of gas.

' 2. A device according to claim 1, in which the baffle wall is provided with a plurality of small openings affording communication between inlet and outlet passages.

3. A combustion chamber for sulfur burners comprising an inclosing wall, inlet and outlet passages through said wall, and a baffle wall between said inlet and outlet passages, the baflle wall being arranged at such an angle to the inlet passage and in such relation to the inclosing wall as to impart a swirling motion to an entering stream of gas.

4. A combustion chamber for sulfur burners comprising a metal shell, a refractory lining therefor, a refractory bafile wall, inlet and outlet passages located on opposite sides of said wall and out of axial alinement with one another and with the longitudinal axis of said passages disposed substantially at right angles to the longitudinal axis of the baffle wall, and a plurality of comparatively small passages through said wall located out of alinement with the inlet and outlet passages.

5. A device according to claim 4:, in which the inlet passage is arranged axially out of normal with the bafi'le wall to impart a swirling motion to an entering stream of gas.

6. A device according to claim 4, in which the shell and lining are cylindrical and of greater height than diameter, the inlet and outlet being located adjacent the bottom and the bafiie wall located diametrically of the shell and at an angle of approximately 45 to the axis of the inlet passage, and a plurality of small passages in the upper part of said bafiie wall affording communication between the inlet and outlet passages.

7. A combustion chamber comprising an inclosing wall, inlet and outlet passages extending through said wall and arranged to extend at an angle to one another and a partition wall between said inlet and outlet extending transversely of the outlet and tangentially of the inlet.

Infl witness whereof I have hereunto set my han FRED B. CHAPPELL.
