FREDEBIUK ALBERT LEWIS, OF MELBOURNE, VICTORIA, AUSTRALIA.
APPARATUS FOR PREVENTING SMOKE.
Specification of Letters Patent.
ratented. March 6, 1906.
Application filed March 22, 1905. Serial No. 251,474- I To all whom it may concern:
Be it known that I, FREDERICK ALBERT LEwIs, manufacturer, a subject of the King of Great Britain and Ireland, residing at 339 Flinders Lane, Melbourne, in the county of Bourke, State of Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in Apparatus for Preventing Smoke; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The object of my invention is to provide a cheap and effective means of arresting the smoke arising from the furnaces of vertical, horizontal, portable, stationary, or other classes of solid-fuel-fired steam-boilers. In the ast a variety of devices have been used to this end; but with my invention, which is cheap both inits application and maintenance, the unconsumed fuel in a state of suspension in the furnace -crown is so attacked that combustion immediately occurs; but in order that my invention may be better understood I will now refer to the accompanying sheet of drawings, which are to be taken as part of this specification and read herewith.
Figure 1 represents a front elevation of a boiler with my invention applied thereto. Fig. 2 is a side sectional elevation through the boiler shown in Fig. 1. The fire-door frame and fire-door are removed. Fig. 3 is a front elevation of a modification. Fig. 4 is an enlarged perspective View of the nozzle attached to the lower end of the combined steam and liquid pipe.
Similar letters of reference indicate similar or corresponding parts where they occur in the several views.
My invention includes (when a spray consist' g of solution and steam is projected over the fire) a solution-reservoir A. This reservoir is of any material and for convenience is placed upon the boiler-to or adjacent thereto, as shown in Fig. 1. 8n the top of this reservoir is a cover B, which may be attached to the said reservoir in any wellknown way. When the cover is removed, the reservoir is charged with liquid. On the side of the said reservoir is a gage-glass C. By this the height of the liquid within the reservoir is disclosed, or instead of a test-cocks may be applied to the slde o the reservoir, or a float may be placed inside the said reservoir connected by a wire, chain, or
gagelass any other means to an indicator on the exterior of the said reservoir. Near the reservoirbottom is attached a dischar e cock or valve D. To this the inlet end 0 the dischargepipe E is connected. The discharge end of the said pipe is affixed to a combination steam-valve S and injector F, placed upon the boiler-front. To the lower portion of the combination steam-valve and injector is attached the upper end of a combined steam and liquid pipe G. The lower end of this is attached to a spraying-nozzle H. This is situated in the crown of the furnace and near the fire-door top. It is so placed that it is nearest to the new-fired coal, and it may have extensions from which to redistribute the spray. The said spray may be either coarse or fine. The spraying-nozzle consists of right and left hand semicircularly-formed extensions. Thesc bear against the furnacecrown and are preforated in such a manner that the spray may be distributed as far as the fire-bridge J. In the furnace-door P is an air-door In the foregoing a solution (hereinafter described) and steam are sprayed over the fire.
In a modification (when the solution sprayed over the fire is unmixed with steam, but forced through by steam) the solutionreservoir A before referred to is under pressure. It has its cover B bolted or otherwise secured to its shell. To charge the reservoir when under pressure, there is attached to the cover a receiving-chamber This chamber is hollow, and above it is an inlet-cock L. Above the said cock is a funnel M. Below the said receiving-chamber is a discharge-' cock N. From the boiler a steam-pipe 0, having a stop-cock R thereon, is connected to the top of the reservoir, and the dischargepipe E instead of communicating with a combination steam-valve S and injector F communicates direct with the sprayin -nozzle H. With the above-mentioned parts t e solution hereinafter fdescribed in an undulated form by steam isforced in a spray over the fire.
The liquid in the solution-tank is obtained by dissolving crystals of sodium N 0 or Chilian or Peruvian saltpeter, cubic niter,sod2e nitras (L) in water. To this end there is added approximately one-half (1}) pound of crystals to one (1) gallon of cold water. This is mixed and thenreservoir. Instead of sodium nitrate o the materials before described being dissolved n water potassium chlorate (K010 or chloplaced in the I nitrate (Na voir.
I reservoir.
rate of potash, potassii chloras, (L,) or potassic chlorate may be used. The dissolution of the above materials is so thorough that no precipitation occurs when in the reservoir.
The cycle of operations when the solution and steam are sprayed'over the fire-top is as follows: The cover of the solution-reservoir is removed and the solution hereinbefore described poured into the same. The dischargecock D is then opened and the liquid runs down to the combination steam-valve S and injector F. The steam-valve on this is op erred, and steam forces the liquid through the combined steam and liquid pipe to the sprayingnozzle H. Steam and solution are thus sprayed. The cycle of operations when the solution only is sprayed over the fire-top, due to the pressure of steam in the reservoir-top, is as follows: The discharge-cock N being closed and the inlet-cock L bein open, liquid is poured into the funnel M. t gravitates downwardly into the receiving-chamber K When the said chamber is full, the inlet-cock L is closed and the discharge-cock N opened. The li uid thereby falls down into the reseren all has escaped, the dischargecock N is closed. The steam-cock R is then opened and also the discharge-cock D on the The liquid fills the bottom of the reservoir, and as the discharge-cock D is open the liquid passes down throu h the spraying nozzle H to the fire. So ution only is sprayed.
Having now described .my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In an apparatus of the class described, the combination with a boiler, of a reservoir positioned upon said boiler, a removable top or cap carried by said reservoir, a valve secured to said reservoir, a combined steam valve and injector secured to said boiler, a
discharge-pipe connecting said valve and combined steam valve and injector, a steam and liquid 'pipe secured to said combined steam valve and injector and extending over the fire-box of said boiler, cured to the lower end of said steam and liquid ipe, said nozzle comprising right and left and apertured, semicircular extensions. 2. In an apparatus of the class described, the combination with a boiler, of a reservoir carried by said boiler, a removable cover or cap carried by said reservoir, a valve secured to said reservoir, a combined steam valve and injector secured upon said boiler and communicating with the interior thereof, a vertical discharge pipe connected to said valve carried by the reservoir and to said steam valve and injector carried by said boiler, a vertical steam and'liquid pipe secured to said combined steam valve and injector, a nozzle secured to the lower end of said steam and liquid pipe, said nozzle comprising semicircular, apertured extensions, said extensions bearing against the furnacecrown.
.3. In an apparatus of the character described, the combination with a boiler, of a reservoir carried by said boiler, a removable cover carried by said reservoir, a valve secured to said reservoir, a tubing or pipe secured to said valve and extendin into and over the fire-box, a nozzle secure to the inner end of said tubing, said nozzle comprising semicircular, apertured extensions, said extensions engaging the furnace-crown.
In testimony whereof I afiix my signature in the presence of two subscribing witnesses.
