' To all whom it may concern produce complete combustion of the fuel will be consumed. This PATENT OFFICE.
CORNELIUS CABLE, 0F ELKHART, INDIANA.
Specification of Letters Patent.
Patented Dec. 8, 1914.
Application filed March 24, 1914. Serial No. 826,969.
Be it known that I, CORNELIUS CABLE, a
citizen of the United States, residing at Elkhart, Indiana, have invented certain new and useful Improvements in Smoke-Eliminators, of which the following is a specification. This invention relates to smoke eliminators or devices that produce complete combustion of the fuel and its gases in furnaces of boilers either stationary or locomotive.
The .objectof the invention is to provide a simple and efficient device that can be readily set up in the stack of a furnace and that will operate by suction to create such a uniform draft through the fire box as to which will give a white heat so that all consequent gases arising from the burning fuel revents the formation of smoke and this iswhy I prefer to call my device a smoke eliminator rather than a smoke consumer.
The invention consists in the construction and arrangement and combination of parts hereinafter described and particularly pointed out in the claim, it being understood that I do not wish to limit myself to the details of the. invention.
The invention is illustrated in the accompanying drawin's in which:
Figure 1 is a diagrammatic view of a large chimney or stack with my device applied thereto. Beside the chimney is indicated a boiler house with a breeching or flue leading therefrom to the chimney. Fig. 2 is a sectional view of my device with a nozzle shown in place in dotted lines. This view is enlarged over the one in Fig. 1. Fig. 3 1s a bottom plan view of the device, and Fig. 4 is a partial sectional view of the particular nozzle I prefer to use in connection with my device.
In the drawings, the'numeral 1 indicates the chimney or stack, 2 the boiler house in which are situated a series of boilers, 3 the breeching or. flue leading from the boilers to the stack, 4 my improved device in position on a bracket 5 in the stack above the point of entry of the breeching. The device has a pipe 6 leading from a steam dome to 1 supply it with live steam. The pipe 6 is further connected by a pipe 6* to a source of compressed air 7 and has a suitable valve 8 so that either steam or compressed air can be used on the device. The eliminator proper is shown in Fig. 2 and is of substantially bell shape. In its bottom, holes or openings 9 are rovided for the admission of air and 10 indicates a threaded shank for supporting the device. An injector nozzle 11 extends through the shank into the device. The nozzle I prefer to use in my device is shown in Fig. 1 which consists of two inverted cones 14 and 15 with their apexes forming a small opening or throat 12. In the cone 14 I prefer to have rifling which I have found in practice, gives the steam a whirling movement that is very advantageous. The cone 1 5 is of smooth bore. On the outside of the 51:16am is provided a collar or hexagonal'nut q l. so positioned thereon as to indicate just :hpw far the nozzle should be screwed into the shank 10. The nozzle must project into the eliminator to a point beyond the air openings 9.
In operation the eliminator is installed in a stack or chimney above the point where the breeching or flue from the furnaces enter the chimney. This is very important. the fires have just been-lighted and there is no steam, compressed air from any suitable" source is passed through the device by means of the valve 8 closing off the steam supply and connecting up the air supply. This creates enough draft to hurry the fire but I have found that compressed air will not produce the satisfactory results that steam does and hence only use air initially. As soon as steamis formed, the air is shut off and steam is conducted to the eliminator. In passing through the rifled nozzle it is given a rotary motion which is of great benefit. The steam in leaving the nozzle 11 fills the open end of the eliminator as indicated by the dotted lines in Fig, 1, and in so doing sucks air into the device through the openings 9, without which a vacuum would be formed, and is mixed with the steam. Further, the steam leaves the eliminator with such velocity that it creates a great suction in the chimney which of course drawsair through the fire box of the furnace and produces perfect combustion. The degree of draft can be regulated by the admission of steam to the eliminator. In
practice, it has been found that when the When for use in the eliminator, I do not Wish to limit myself to this, as any ordinary steam nozzle or jet Will suffice. Further, Ihave described my device in use in a stationary furnace, but it can be'used equally well in a locomotive.
What I claim is: In combination, a stack, a furnace, a flue leading from the furnace to the stack and a draft inducer located in the stack above the point of entry of the fine comprising a bell.
shaped device arranged vertically in the stack and having an enlarged open upper end with openings through the bottom, a jet entering centrally of the bottom, aidraft space being provided between the bell and the Walls of the stack, substantially as described. j
In testimony whereof; I aflix my signature in presence of two Witnesses.
