F rality of superimposed bailies which ai Patented Nov; 24, 1925.;




Application filed October 6, 1924. Serial No. '(42,035.

To all whom, it may concern.

Be it known that I, ANDREW W. l/VAnn, a citizen of the United States, residing at Charleston, in the county of Kanawha an State of West Virginia, have invented new. and useful Improvements in Smoke Condensers, of which the following is a specification.

This invention relates to a means for con- (lensing smoke, and of obtaining therefrom and holding in solution all the by-products of coal. I

The primary object of the invention is the provision of a smoke condenser, capable of application to any stack carrying the combined gases and solid particles, known as smoke from boiler fires or the like, wherein the solid particles of the smoke, and soluble gases are removed by the intermingling therewith of exhaust steam and water in theform of a spray.

A further object of the invention is to provide a device of this character in which the smoke is caused to travel around a aluin separating the solid particles from the smoke.

WVith these and other objects in view, which will appear as the description proceeds, the invention consists in the novel features of construction, combination of elements and arrangements of parts hereinafter to be fully described and claimed.

In the accompanying drawing forming a part of the specification:

Figure 1 1s a vertical longitudinal sectional view of the improved smoke condenser operatively assoclated with a smoke stack; and

Figure 2 is anenlarged fragmentary de-' tail view of a ortio'n of one of the Water supply pipes illustrating theassociation of the s'ray nozzle therewith. Re errmg to the preferred embodiment of the invention as illustrated. in the accompanying drawing, the numeral 1 designates a smoke stack of the ty e usually located on the roof of the building, and having connection with the fire box for. carrying elf the products of combustion arising therefrom. i

To the stack 1 is secured by rivets or the like, as at 2, the substantially horizontal elongated tube 3, which is substantially equal'in diameter to the stack 1, and has its Damper 5 pivotally mounted withinthe stack 1 above its connection to the tube 3, directs the smoke from the stack through the tube and into the tank 4.

The pipe 6 which passesthrough one side of the tube 3, and has its open end disposed centrally of the tube and turned toward the tank, serves to inject exhaust steam so that it mingles with thesmoke and absorbs the solid particles and soluble gases therefrom. The smaller pipes 7 which are provided with valves 8 have their ends 9., carrying nozzles 10, disposed in a like man her at spaced intervals within the tube 3, and inject water in the form of a spray which condenses the steam and with it the solid particles and soluble gases from the smoke. The water is permittedto flow out through the valved outlet 11, and ma be treated to' obtain the valuable by-pro note which it contains.

A plurality of horizontal vertically spaced balfle plates 12 are so arranged Within the .tank 4 that alternate plates extend from opposit-e sides and have their free ends spaced from the walls of the tank, which construction insures that any steam not condensed in the tube 3 and the absorbed matter carried thereby, will be deposited by the smoke in its passage through the tank and return by gravity to the bottom.

The conical top 13 serves to direct the remaining gases from the tank 4 either through the pipe 14 back into the stack 1, above the damper 5 or, as indicated by dotted lines in Figure 1 of the drawing the pipe 14 may extend vertically upward mm the tank 4 the necessary distance to provide a draft equal to that of the stack 1.

It will be observed that although the path of travel of smoke from the fires to the top of the stack is considerably lengthened, it is not obstructed sufficiently to affect the natural draft requiredvby the fires.

In practice the tube 3 is five inches in diameter, while the pipes 7 are each half inch indiameter. The nozzles give What is known as a mist spray.

The use of exhaust steam is not only best from the standpoint of economy, but it causes a more perfect condensation of the smoke. The use of the water pipes quickens the condensation.

It will be observed that all of the jets project away from the stack in the branch or pipe 2 of the condenser. By this arrangement an artificial draft is created in the apparatus which is suflicient to counteract the draft loss due to the baifles. Also the condensate is blown along this horizontal branch toward the outlet 11, so that none is permitted to flow back into the stack.

Having thus fully described my invention, it will be obvious to those skilled in the art to which it appertains that it is susceptible of various minor changes as to the details of construction within the scope of the appended claims, without departing from the spirit of the invention.

What is claimed is 1. In combination with a stack, a substantially horizontal elongated tube having one end secured to and communicating with the stack to receive therefrom the roducts of combustion, a damper provide in the stack above the connection of the tube thereto to direct the said products into the tube, a pipe for supplying exhaust steam communlcating with the tube at a point adjacent the connection of the tube to the stack and having its inner end turned in a direction away from the stack, and a series of smaller pipes entering the tube at points spaced from the exhaust steam pipe, said smaller pipes being supplied with water and having nozzles at their ends within the tube to dischar e water in the form of spray to condense t e steam, said smaller pipes being spaced from each other, and a tank into which the outer end of the tube discharges.

2. A smoke condenser comprising a substantially horizontal flue portion, an exhaust steam nozzle adjacent to the smoke inlet thereto and discharging longitudinally thereof, a plurality of water spray nozzles arranged in the path of the discharging steam within said flue and also discharging longitudinally thereof, a substantially vertical extending enlargement connected to the discharge end of said horizontal flue portion havm a pluralit of substantially horizontal ba es arrange in staggered and overlapping relation, an outlet flue connected to t e enlargement, and a valved drain outlet for the water which collects in the bottom of said enlargement.

In testimony, that I claim the foregoing as my own, I have hereto aflixed my signature.
