Patented Mar. 5, 19,12.
To all whom imaylconcem Be it known that we, GUsTAvE A. lnorrN, of Coarsegold, Madera county,v California,
' and EvERALDo' M. ARREAGADA, `of the city and county of San Francisco, Stateoi California, both citizens of the United States, have invented new and useful Improvements p in Power-Generators, of which the following is a specification.
This invention relates to a; fluid pressure generator. v
It is the object of this invention to provide a means for generating fluid pressure from the combustion of volatile oils, inl which the products of combustion will be in termingled with steam athigh pressure to be drawn oli' and utilized therewith in the operating of power generators, such as turbines, steam engines and the like.
A further object is to provide a. fluid pressure generator of the above character, whiclk is simple in construction and operation, economical in space, and readily accessible for cleaning and repairs The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1-is a vertical section of the i vention. Fig. 2y is a horizontal section oli the, line X-X, Fig. 1. Fig. 3 isa horizontal v section on the line Y-Y,l*`ig.y 1.
In the drawings, A represents a vertically arranged, cylindrical boiler shell, the upper and lower ends of which are closed by means of plates B and C respectively in the usual manner. Extending upward a-shortdist-ance within the shell A is a .cylindrical fire box 2, the peripheral wall of which is spaced from the inner face offthe shell A toy form av water jacket.
A serles of fire tubes 3 mounted on the lire box 2 extend upward in the shell A and open beneath a baiiie plate 4 disposed horizontally a short distance below the upper A end of the shell Aon the interior thereof.
The plate 4 forms the bottom of an inclosed drum or head 5, which is s aced from theinner wall of the shell A an is connectedto a suitable source of water supply by'meansy of a pipe 6.. A discharge pipe leadsdownward from the drum 5 and terminates a short distance above the top ofthe fire box 2 andopens to the interior of the shellA'.
Mounted within the fire box 2 is aL cylindrical combustion chamber 8, the side walls and top of which parallel those of the lire box 2 a short distance therefrom. Arranged vin the combustionchamber 8 is a generator which is formed with a central, vertically f disposed chamber 9, which opens at its up-v per end to the combustion chamber 8 and is closed at its lower end by the nozzle of a needle valve 10. The chamber 9 is. surrounded byva thin wall or partition which".
sepa-rates it from an annular chamber 11, which chamber 11 communicates with lthe 'chambery 9 through perforations a-b; the perforations a leading from the top of the chamber 11 and the perforations b leading from the bottom thereof. The chamber 11 is inclosed by a cylindrical wall which sep- /arates' the chamber 11 from an inclosed spiral passage 12, which winds around the chamber 11 and opens thereto at its upper end; the Apassage-12 being connected with'a pipe 13 leading yfrom any suitable source of air supply. The' needle valve 10 has a pipe -coil'14 connected therewith, which coil leads from any suitable source of liquid vfuel supply and is disposed over a prlmary generating pan 15.
The upper 'portion of the shell A constii i tutes a steam chamber from which apipe 16 leads to anyisuitable engine or power generator. The/cap or end plate B is fitted with l a pressure gage 17 and a blow-ofi' cock or pop valve 18. A water gage 19 is mounted on the shell A in the `usual manner and a draw-oi pipe 20 is provided, through which ythe shell may be emptied when desired.
In operation, a volume of water is first admitted to the shell -A through the pipe 6, drum 5 and pipe 7, the water filling the shell to a 'point a short distance below the upper ends of the tubes 3, as shown in Fig. 1; a vent'plug 21 in the upper end of the shell A being removed to admit of the escape of the air displaced by the `incoming volume of water. The shell A being thus filled, the plug,
23, which is then closed by meansof a plug 24. In the meantime a quantity of inflammable substance has been ignited in the generating pan 15, the blaze of which envelops1 the coil 14, heating it sufficient-ly to convert the ,volatile .oil therein.into a combustible gas. The needle valve is then opened and the generated gas is discharged into the chamber 9 belowa gauze screen 0 therein;l this gas mingling with a small quant-ity of airdelivered through the perforations 1),? which air has previously been superheated by its passage from the pipe 13 around the spiral passage 12, which passage has been heated by the burning of oil in the combustion chamber 8, as before described. This mixture of gas and air on passing through, the screen 0 vis mixed with heated air dlscharged through the perforations a, which air is of suiicient volume and temperature to cause combustion of the gases at this point. This having occurred, the use of the generating pan 15 is dispensed-with', as the v olatile oil will be' Vaporized by its passage through the screen 0. The llames from vthe burning gases and the heat generated thereby pass through a number of perforations d in the walls of the combustion chamber and enter the lire box 2, thence pass upward through the flues 3 and impinge against thev battle plate 4 tending to4 heat the latter to a high degree. rlhese gases then pass beneath a downwardly extending lange on the plate 4 and enter the steam space above the waterlevel in the shell' A.. ln themeantime, the heat in thefire box 2 and tubes 3 is transmitted to the water therearound, causing the water te'boil and thus generate steam, which also collects in the steam space in the upper end of the shell A. together with the heated air and products of combustion discharged from the lues 3.
lt is to be noted atthis point that the air delivered through the pi e 13 tothe assage 12 and combustion cham er 8 is un er a cer. tain forced pressure and that the volatile oil delivered through the needle valve 10- enters the combustion chamber 8 at a like' pressure, which pressure is .necessarily in excess of the steam `pressure permitted in the steam space, so as to insure the passage of the `air upwardA through the lines 3; the blow-olf or safety valve 18bein` set to admit of the automatic release o the steam pressure when the latter reaches a point approximately'that of the air pressure when the pressure generated as before described i is not discharged suiciently fast throughthe delivery pipe 16. As soon as the pressure of steam in the steam space or dome reaches the desired degree, water is discharged into thedrum 5 through pipe 6 at pressure equal to that of the air delivered through the pipe 13, which is in excess of the normal. steam pressure. The water in the drum 'becomes heated by the action of quently expanded in the spiral passage 12 and the volatile li uids being vaporized in the chamber'9 un er pressure.. The pressure thus generatedwill be delivered tothe steam dome from whence it is drawn off v through the pipe 16.
From the foregoing it will be seen that as the steam and air mixture in the steam dome is i drawn oli", additional Water to take 'the place of that evaporated will be discharged throughthe pipe7 the inflow of water be ing regulated tocorrespond with the amount evaporated to maintain a fixed water level,
and that by -reason of the constant drawing ofi' of the' pressure above the water level `there will be a constant flow of air. and com! -bustible gases from the fire box 2. The
faster the pressure is drawn od through the pipe 16, the Agreater the velocity of the air discharged through the perforations a, thereby increasing the llame at this point.
' As a means for preventing thesteam ris ing` from the surface of'thewater in the shell from coming in contact with the underside of the `plate 4 and there condensing and dropping into the tubes 3, a baliie plate or barrier 25 is mounted pn the pipes 3 be-4 tween the normal level of the water'and the plate 4.
When it is desired to gain access to' the interior ofthe shell, 4 or rebox 2, the plate l is removed after the shell has been emptied with the flues 3 may then befwithdrawn from the shell A for cleaning. It is manifest that by reason of the pressure on both sides of the rebox being practically equal,
light material. Havingy thus described our invention, whatwe claimand desire to secure by Letters VPatent is-'- y 1. In an apparatus of the character devthrough the draw-'off pipe v20.
