SMOKE-CONSUMER.
Specification of Letters Patent.
Patented Jan. 2, 1906.
Application filed July 7,1905. Serial No. 268,626.
To all whmn it may concern:
Be it known that I, GEORGE M. BooNn, a citizen of the United States, residing at Baltimore, Maryland, have invented certain new and useful Improvements in Smoke-Consumers, of which the following is a specification.
My invention herein described relates to devices for feeding air to furnaces of that class in which the air as it enters the firechamber over the fire-bed is given a whirling movement for the purpose of more thoroughly mixing the air with the unconsumed products of combustion and effecting more thorough combustion, both for economy of fuel and to prevent the nuisance of smoke.
I have sought in this invention to provide a simple and cheap device and one which may be readily applied to any form of furnace and which will set up the required ghirling movement in all parts of the fire- My said invention is illustrated in the accompanying drawin s, in which Figure 1 shows t e device in front view. Fig. 2 shows a section on line 1 1, Fig. 1. Fig. 3 illustrates the device in a modified form and as applied to the door in a vertical boiler. Fig. 4 shows an inside elevation of this modified form. Fig. 5 shows a front view of the door with the air-opening and draft-regulator.
The device shown is approximately in the form of a turbine-shaped deflector and is preferably formed out of a plate of stout sheet-steel, substantially circular. It is out with radial slots 1 from the hub 2 through the edge,which slots form blades 3, and these are struckup, curved approximately in the form of propeller or turbine blades, but preferably with low pitch. I have shown in Figs. 1 and 2 these blades as equal in form and extent, and this is the form adapted to furnaces with horizontal boilers. A sleeve 4 is bolted to the hub' of this deflector, on the inside thereof and at right angles to the hub, by a bolt 5, passing through a hole in the hub and held by a nut 6, thus immediately securing the deflector to the door. This is shown in the sectional View, Fig. 2; but the method of attaching the door is more clearly seen in Fig. 3. In this figure the air-passage through the inner wall of the door is shown at 7. A similar opening 8 is made in the outer wall, excepting that a bar is left in the metal at 9 to receive the bolt in the sleeve, which bolt passes through the bar and is held by the nut. The outer edges of the blades bear at their corners upon the inner surface of the door, to which they are drawn snugly by the nut and with force enough to hold the deflector in place by frictional contact. The curve of the blades is such that the air drawn in from the outside and impinging upon the inner surface of the blades will be directed through the slots, and thus a whirling motion transversely of the chamber and toward the rear is set up. The device is preferably so located in the dooras to discharge the air drawn through the hole equally into the fire-space above the coal with a force proportioned to that of the draft.
In Fig. 4 I have shown a modified form of the deflector for vertical boilers, in which form one blade (the lower) is extended to guide the air father inward and deflect it to prevent too much cooling of the door-frame below.
The device is simply and cheaply made of the ordinary boiler-steel and may be applied readily to any furnace-door. The indraft of air keeps it cool, and, asI have found by practical use, it so increases the combustion of the carbon heretofore ordinarily unconsumed in the smoke that the boiler-tubes are left free from soot and the smoke either materially diminished or prevented altogether. For the purpose .of regulating the draft I prefer to fix over the draft-hole a shallow casing 10, provided with air-passages 11 and a valve 12, with registering passages 13. This casing may be cast and aflixed to the door in any convenient way; but as the hole in the door for the admission of the air varies with the size of the furnace I cast the casing inthe exterior form of a frustum of a cone and cut it to suit the air-hole in the door, as illustrated in the dotted lines 13 in Fi 3. As this prevents the casting of the ox with a flange, I provide lugs 14, which may be bolted to the casing and the outside wall, as shown in Fig. 3.'
I claim 1. In combination with the door of a furnace having a hole for the passage of the air, a turbine shaped deflector immovably secured to the door on the inside thereof and opposite the hole and arranged to set up a whirling movement of the air and products of combustion substantially as described.
2. In combination with the door of a furnace having a hole for the passage of the air, a turbine shaped deflector immovably secured to the door on the inside thereof and opposite the hole and arranged to set up a whirling movement of the air and products of combustion, and means for regulating the air-supply thereto, substantially as described.
3. In combination with the door of a furnace having a hole for the passage of the air, a turbine-shaped deflector immovably secured to the door on the inside thereof and opposite the hole and arranged to set up a whirling movement of the air and products of combustion, and a shallow casing provided with air-passages and a valve regulating the air-supply to said passages, substantially as described.
4. In combination with the door of a furnace having a hole for the passage of the air, a deflector immovably secured to the door opposite the hole and having a series of turbine blades, one of said blades being of greater length than the other blades, substantially as described.
In testimony whereof I affiX my signature in presence of two Witnesses.
