SMOKE CONSUMING OR CLEANING. DEVICE 3 Sheets-Sheet Filed Nov. 28; 1927 Patented Jan. 14, 1930 UNITED STATES WILLIAM IE. BRINKMAN, JP, OF ST. LOUIS, MISSOURI SMOKE CONSUMING OR CLEANING DEVICE Application filed November 28, 1927. Serial No. 236,139.

This invention relates to smoke consuming and cleaning devices.

An object of the invention is to provide equipment for boilers, furnaces and the like, for injecting jets of a mixture of superheated dry steam and preheated air into the boilers and furnaces in a direction to remove the solid and combustible elements from the smoke and to cause more perfect combustion l0 and thereby increase the efiiciency of the boilers and furnaces equipped with the device.

Another object of the invention is to provide a novel relationship of the present invention with a boiler or furnace structure, so as to prevent escapeof substantial amounts of solid and combustible elements with the smoke and gases passing from the boiler or furnace.

Other objects will appear from the following description, reference being made to the accompanying drawings in which Fig. 1 is a vertical longitudinal sectional view of one type of boiler embodying the present invention.

Fig. 2 is a vertical longitudinal sectional view of another type of boiler having the present invention arranged in a different relationship from that shown in Fig. 1.

Fig. 3 is a vertical longitudinal section of one of the steam heating and injecting devices.

Fig. l is an outer end elevation of the device shown in Fig. 3.

Figs. 5, 6 and 7 are vertical cross sectional views on the lines 5-5, 66 and 7-7, respectively of Fig. 3. t

Fig. 8 isa perspective view of a preferred type of nozzle used in connection with this invention.

Vhile I have shown the invention arranged in one relationship in one type of boiler and in a different relationship in another type of boiler, it will be understood that the invention may be applied with equal advantages to other types of boilers and to furnaces.

tudinal section of a familiar type of boiler having a combustion chamber 1 into which fuel may be delivered through a chute 2 or a door 3, as desired. The wall 4 extends above the grate of'the combustion chamber 1 and Fig. 1 will be recognized as a vertical longiprevents the passage of solid fuel into the rear chamber 5 which extends be ow the plane of the grate of the combustion chamber. The smoke and gases from the combustion chamber and bearing solid and other combustible elements rise in the combustion chamber 1 and pass rearwardly above the upper edge of l the wall 4c and into and through the chamber 5 to the boiler tubes. By the present invention the solid elements are removed from the smoke and gases and practically all of the combustible elements are consumed in the furnace.

The injector devices are mounted in openings in the walls of the combustion chamber of the boiler and elsewhere, as desired. Each injector device comprises an outer wall 6, aninner wall 7 enclosed within and spaced from the outer wall and united therewith by an outer end wall portion 8 and an inner end wall portion 9 closing the end of the space between said inner and outer walls. A horizontal partition wall 10 withinv the space between the inner and outer walls of the device at each side of the inner portions 7 extends from the outer end 8 toward the inner end wall 9 and terminates a slight distance from said inner wall 9 leaving an opening through which steam may pass from the under side to the upper side of the partition 10. These partitions 30 10 are united with the outer and inner walls 6 and 7 and with the outer end wall 8 so that the steam admitted into the outer end of the space below the partition 10 must pass inwardly below said partitions to the inner end. wall 9, 55 and thence upwardly above the partitions 10, and outwardly through the space above said partitions to the spray nozzle} The tube formed by the inner wall 7 is Venturi-like, having a thickened portion 11 flaring outwardly and inwardly and leaving a restricted opening 12 of less diameter than the diameter of the passage through the tube 7 at the inner and outer ends of the device.

The outer wall 11 of the thickened por.- tion inclines sharply to intersection with the wall 11, which forms an opening of approximately uniform diameter to its intersectionwith said inclined wall 11. The inno ner wall 11 of the thickened portion 11 inclines gradually to the inner end of the tube 11, thus forming a mixing chamber for the superheated steam and preheated air as hereinafter explained.

A steam supply pipe 13 opens into each of the devices above described through a branch pipe 14 capable of independent control by valves 15. These branch pipes 14 open into the space below the partitions 10, so that the steam passing from said pipes must circulate as above described. F rom'the outer end of let pipe 17 and its nozzle 18 to the Venturi tube structure the injection of steam through the Venturi tube draws with it a proper amount of. air which becomes thoroughly 'mixed with the steam in the Venturi tube and preheated t0 the temperature of the steam before injection into the boiler or furnace. This mixture of superheated steam and preheated air separates the combustible elements from the escaping products of combustion and causes said combustible elements to be thoroughly burned and consumed within the boiler or furnace. The pipe 16 is equipped with a valve 20 to regulate the passage'of steam therethrough.

In the relationship shown in Fig. 1 a num ber of these injector devices are mounted in openings in the combustion chamber wall out of vertical and horizontal alinement and are controllable to inject jets of heated or superheated ,dry steam transversely and, preferably, longitudinally of the combustion cham her at different heights above the fuel in the combustion chamber. Also, one of these injector devices is preferably mounted in the rear end wall of the chamber 5 below the plane of the upper edge of the wall 4, and another of the injector devices is mounted in one of the side walls of the chamber 5 below the plane of the injector device in the end wall.

of said chamber., These injector devices are capable of independent. control by their valves 15 and 20,. previously described. At leastvone of the injector devices opening through the side wall of the. combustion chamber 1 is below the plane of the upper edge of the wall 4,'and another of said injector devices is above the plane of the upper edge of said wall 4 and nearer the space above said wall thanthe injector device that is below theplane ofthe upper edge of said wall. Thus, the injector devices are arranged to inject jets of steam to remove combustible elements from the products of combustion passing from the combustion chamexplained. a

In the type of boiler shown in Fig. 2, a number of injector devices open through the side wall of the firebox 21 above the level of the fuel therein, and in different horizontal and vertical planes, so as to inject jets of steam to intersect the'escaping products of combustion and to remove therefrom the combustible elements. It will be understood that these injector devices are capable of independent control b the valves 15 and 20, so that the injection 0 steam may be regulated as desired.

The inner end walls 9 of the injector devices protrude beyond the inner surfaces of the walls in which the. injector devices'are mounted, so that the ends of the injector devices become heated to a high degree. Sufficient air may be drawn through the Venturi tubes 7 and mixed with the steam and combustible elements of the products of combustion to obtain nearly perfect combustion of all of said elements. I have found by actual practice ofthis invention that it is very efiiclent in connection with different types of boilers and furnaces,

and that by-proper adaptation the invention may be used in various structures. I contemplate such adaptations and alluses to which the invention may be applied.
