APPARATUS FOR MANUFACTURE OF GAS.
SPECIFICATION forming part of Letters Patent No. 549,657, dated November 12, 1895.
Application led June 25, 1894. Renewed May 4, 1895. Serial No. 548,166. (No model.)
To all whom it may concern.'
Be it known that 1, HENRY M. PIERsoN, a citizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have invented a new and useful Improvement in Apparatus for the Manufacture of Gas, of which the following is a specification.
My present invention is designed asv an iinproveinent upon the method and apparatus described and shown in Letters Patent granted to me July 5,1892,No.478,459, and June 27, 1893, No. 500,424, which patents describe peculiar methods and apparatus for the mannfacture of coal-gas, water-gas, and oil-gas, which gases are commingled to form a permanent compound gas as a substitute for natural gas; and the object of my present invention is to render more perfect, efficient, economical, and productive the methods and appara tus therein set forth. v
My present invention relates particularly to improvements in blowing up the generating-furnaces and heating inclined coal-gas retorts and in the admission of air to effect complete combustion; also, in the economin cal treatment of the steam and liquid hydrocarbons preparatory to their utilization in the manufacture of the water-gas and the oilgas.
In my present invention, as in my former vpatents herein mentioned, thegeneratingfurnaces are blown up and the products of combustion are employed to heat the lower ends of inclined coal-gas retorts to a high intermittent heat, and in connection with an additional iire to heat the higher ends of said inclined coal-gas retorts to a steady but relatively low heat, while bituminous coal in said erating-furnaces after the fuel therein arrives at a lower temperature, the oil-gas being conducted down through the bed of fuel in the generating-furnaces, which bed of fuel becomes a fixing-chamber, transforming the oil-vapors into a iXed gas, which is thereafter conveyed away to the same holder in which all three gases commingle to form a permae nent compound gas.
In my present invention the products of combustion resulting from starting under natural draft and from blowing up the generating-furnaces to incandescence are conveyed by a pipe outside said generating-furnaces into the side of the retort combustion-chamber, and said pipe is provided with a valve adapted to shut off the same completely, and the sides of the retort combustion-chambers are each provided with an opening, a lined bonnet, and with a vertically-movable tile, and the end of the aforesaid pipe is provided with a flanged sleeve, which is adapted to be moved up toward or against the end of the bonnet after the valve has been unseated, and when these parts are brought together and the tile elevated a direct opening is established between either generating-furnace and the retort-furnace and retort combustion-.chambers. The generating-furnaces are started under natural draft with the sleeve drawn up tightly against the under side ofthe bonnet. When the generating furnaces are being blown up to incandescence, the sleeve is partially or entirely lowered to admit air to the desired extent with the products of combustion to vinsure perfect combustion of the gases in the retort-furnace and combustion-chambers- The products of combustionpass up through the retort combustion-chambers, the majority of 'said products passing directly vertically and by their high heat heating the lower ends of the inclined coal-gas retorts to a high heat, and the smaller proportion of said products of combustion pass to the higher ends of said coal-gas retorts, heating them to a lesser degree. There is also a fire burning constantly` When the flanged sleeve is lowered and the valve putin position and the tile lowered, the mouth of the bonnet is open and atmospheric IOO air can enter and surround the exposed parts to keep them all cool, and also while either tile is lowered all access to the retort combustion-chambers at that side is shut off. The pipes for the water-gas from the upper ends of said generating-furnaces are connected to the pi'pes that pass oif for the products of combustion, and when the valve heretofore spoken of is in place on its seat the water-gas is forced to pass off in the appointed channel, which channel is the same, and through the same means as were described and shown in my aforesaid patents.
I utilize the heat produced in the retort combustion-chambers for increasing the heated condition of the steam employed in the manufacture of the water-gas and the oil employed in the manufacture of the oil-gas by causing the same to pass through series of pipes that are located in cavities or pockets formed in the brickwork above the retort combustionchambers. rlhis location is exceedingly convenient, because directly above the arch of said combuStien-chambers there is a great amount of heat that would otherwise go to waste, and as it is essential to bring the steam to the highest condition of heat before separating its constituent elements and to bring the oil to as high a heatas is safe before transforming it into oil vapor I employ pipes placed in these pockets and arranged in the peculiar manner hereinafter set forth.
In the drawings, Figure l is a vertical longitudinal section and partial elevation at the line .fr a of Fig. 2. Fig. 2 is a vertical crosssection at the line y y of Fig. l, and Fig. 3 is a sectional plan at the line e' z of Fig. l. These iigures show the general location and construction of the respective parts. Fig. 4 is a side elevation of the pipe, valve, and bonnet connecting the gencrating-furnace and the retort combustion-chamber. Fig. 5 is a sectional plan at the line 1/ of Fig. 4. Fig. G is a partial elevation and vertical section of the same parts, and Fig. 7 is a plan of the band for holding the tile. Fig. S. is a vertical section at the line y y of Fig. 9 of the upper end of the retort combustion-chambers, showing the pipes for steam and oil and their respective pockets; and Fig. 9 is a plan view of the same. Fig. 10, in larger size, represents the particular construction of the series of pipes for steam and oil.
A B represent the companion generatingfurnaces.
C D represent the retort combustion-chambers surrounding the lower ends of the inclined coal-gas retorts e.
II represents the combustion-chamber surrounding the higher ends of the inclined coalretorts, and l-I the retort-furnace beneath said combustion-chambers, and this retortfurnace II has entrance-doors a2, grate-bars a3, and ash-pits, and a chimney I connecting with the eombustion-chamber II carries the products of combustion away.
There are uptakes or throats c c2, that conneet the retort-furnztee with the retort combustion-chambers C D, and there are uptakes e4 and e, that connect the retort-furnace ll with the combustion-chamber II. The uptakes or throats c e2 are properly of at least three or four times the area of the uptakes e e5, the uptakes c e2 being directly vertical and the uptakes c'1 e5 being inclined to the combustionchamber II, and at the upper end of the retort combustion-chambers O D there are openings C D', which connect the retort combustion-chambers with the comlnistionchamber H, so that the products of combustion may pass over the intervening wall and away by the chimney I.
In the upper portionof the ln'ielm'ork above the combustion-chambers C, I), and 1I are the pockets or receptacles Il F for the pipes for steam and oil, hereinafter described. The retort-furnace II is arranged slightly differently from what is set forth in my former patents, in that the ire is central and the entrance thereto through the doors a2 is beneath the brickwork through the arch G at the back, and this fire is fed by red-hot coke taken out of the inclined coal-gas retorts e, which is passed down the central opening or chute o from the platform above the generatingfurnaces.
The pipe a extends out from the upper portion ofthe generating-furnace I), and the pipe l) connects therewith and extends downwardly to the upright pipe c. The pipe g extends olf from the pipe a to convey the water-gas, as set forth in my former patents. These pipes are lined with tiling andare duplicated upon the opposite side of the generating-:ffurnace A, and as both sets are alike one only will be particularly described.
The upper end of the pipe c is made with a conical seat for the valve d.. The valve (Z is hung upon the end of an' arm d', upon whose back end is an adjustable weight 2. An armj", connected to the pipe c, carries a roller 3 at its upper end, and said upper end is grooved to receive the arm fl,which rests upon said rol ler. Pivoted to this arm rl is a rod h, which passes through the platform 7L and is provided with a handle a at its upper end. This rod is slotted for a pin 5 in a bearil'ig-block fastened to said platform 7i. The under surface of the arm d is cut away and by preference is notched at G.
In the position shown the valve d rests in its seat at the upper end of the pipe c and the back end of the undercut portion of the arm d comes against the roller Now if itis desired to remove said valve, the atten dant upon the platform 7L' pulls upon the handle et of the rod h, raises the valve olf its seat and swin the rod 7l. to carry the valve baclnvardly. This movement brings the valve over into the dotted position shown in Fig. et, wherein the notch (5 engages the roller 3 and the downward movement of the rod h is arrested by the end of the groove in the rod h stopping against the pin 5. The valve is thus supported out of IOO the way until again required. When the valve is returned to its normal position, the end of the undercut portion of the arm d' comes against the roller 3 and insures the valve dropping into place.
A flanged sleeve surrounds the upper end of the pipe c and pins '7 project from opposite sides of said sleeve, These pins are engaged by a slotted yoke-frame i', one of whose ends is pivoted to the arm Z2, secured to the pipe c, and the other end of the slotted yoke-frame fr" is pivoted to a vertical rod k, with a handle at the upper end and with one or more hook-- ing projections S. This rod passes up through the platform h and through bearing-blocks therein which are provided with a pin 9. the position shown in Figs. 4 and 6 the sleeve is down at its lowest point at rest upon the projections 10 of the pipe c. The attendant to elevate the flanged sleeve raises the arm Za to bring its projection 8 over the pin 9 to hold the sleeve inv its elevated position. The lined bonnet is secured to a frame Z', which in turn is fastened to the side of the retort-furnace H' at the opening therein, and I prefer to make this frame Z with an annular flange 11, that sets into the brickwork. This frame Z is open at its upper end `and is made with an annular recess to receive the tile-slab m. This tile-slab is provided with a metal band near the top, which band is preferably composed, as shown in Fig. 7, of the two parts n n and the bale n2, bolts 12 holding the bands together and to the bale, there being small projections 13 on the inner faces of said bands that take into openings formed in the tileslab m, so as to insure the lifting of the tileslab by the bale and bands, and I employ a chain n3 with a weight n4 at its end passing over the pulley 115. This weight is equal to the weight of the tile-slab, so that whether the tile-bcdown or be raised the parts are balanced and remain iiXed.
-I prefer to form annular surface recesses around the upper end of the pipe c at 14 beneath the surface of the iianged sleeve, so as to provide for the ready up-and-down movement of the sleeve and prevent the risk of the same sticking or working too tight.
In the operation of the parts just described, when it is desired to blow up the generatingfurnaces to incandescence, the valve of the water-gas pipe, as shown in my aforesaid patents, is closed, and the valve CZ is thrown open, and the iianged sleevez'isuntouched or is partially raised toward the under edge of the lin ed bonnet, and the tiled slab m is raised, so that an opening is formed through the frame Zl without raising the slab out of the frame, its under edge being approximately up to the upper edge of the opening. is provided for the products of combustion from the generating-furnaces to the retortfurnace I-I and upwardly to the retort combustion-chambers C D and combustion-chamber I-I, so that with the blowing up of the generating-furnaces the lower ends of the in- InI Thus a free passage clined coal-gas retorts are heated to the highest heat and the upper ends to the lowest heat, the products of combustion all passing away by the chimney I.
In blowing up the generating-furnaces to incandescence, as heretofore stated, air is to be admitted with the products of combustion through the lincdbonnet by either leaving the flanged sleeve entirely down or by slightly elevating it to the desired extent, so as to produce an annular opening around the bonnet and between its edge and the edge of the sleeve. This can be done to the extent desired by the operation of said sleeve by the rod 7c and yoke-frame c" and the parts be so held. In this manner perfect combustion is insured in the retort-furnace and combustion-Chanibers, and the parts of the apparatus are not injured by the heat produced. If now it is desired t0 make water-gas, flanged sleeve "Z is dropped, the valve CZ replaced, the tile m dropped into the frame Z', and the valve of the water-gas pipe of my former patents opened. The steam is then admitted to the generatingfurnace to produce the Water-gas,which is conveyed away, as heretofore set forth.
The series of pipes employed for increasing the heat of the steam and the oil, and which pipes are located in the pockets or openings E F directly above the combustion-chambers C, D, and H, are preferably made as follows: Care must be exercised in heating the oil or liquid hydrocarbons so as not to raise the same t'o too high a degree of heat, but the steam is not subject to such risk. Therefore in heating the liquid hydrocarbons I prefer to pass the same in pipes through a steam-jacket, wherebythe heat above these combustion-chambers will not only increase the heat of the steam,b ut will also highlyheat the oil. This same steam is then taken through a second set of pipes back and forth and heated to a veryhigh heat.
In Fig. 10 Ihave illustrated two sets of pipes for these purposes, and I might here remark that the pockets or openings E F in the brickwork open at the upper higher end and are provided with closing doors 14 15 and the oil and steam are conducted into and away from said series of pipes from the lower end, which lower end is nearer and more convenient for the utilization of said steam and oil in the generating-furnaces.
The oil or liquid hydrocarbons pass by a pipe o into and through steam-pipes r', the steam passing into said pipes by the inlet r, the oil passing on back and forth through the series by the pipes and the exit-pipe 0,', the steam also passing on back and forth through the pipes r/ and the return bends r2 to the exit-pipe r3. -I have shown a series of pipes and their connecting ends as suitable for conveying the liquid hydrocarbons through the steam; but do not limit myself to this precise construction, as the same is not essential, the object to be attained is, as stated, in carrying the liquid hydrocarbons through steam-pipes, the steam being vsubject to the IOO IIO
`down to the generating-furnaces heat above the retort combustion-chambers and in turn heating the liquid hydrocarbons. The steam from the pipe r3 passes over into the second series of pipes, which, as shown in the drawings, Fig. 9, is located above the retort combustion-chamber C and one combustion-chamber H. This series is one pipe s within another and outer pipe s2 with suitable connecting heads, so that the steam passes through each length of pipe s2 into the open end of the inner pipe s, back therethrough, crosses over to the next set, passes through the outer pipe s2, and returns back through the smaller inner pipe s', and so on through the series, and finally emerges by the exit-pipe s, and therefrom branches extend In this way the liquid hydrocarbons are heated to such an extent that upon coming into the generatingfurnaces they are in a greatly-advanced condition to be transformed into a fixer gas by being conducted down through the fuel in the generatingfurnaces, which become the fixing-chamber, and the steam employed in the manufacture of the water-gas is heated to such an extent that it is more readily and economically separated into its component parts in the manufacture of waterin gas when passed into the generating-furnaces.
By the means heretofore described my improved apparatus for the manufacture of gas is rendered more efficient and economical, and the operations performed are carried out with the greatest amount of safety and se curity and with the greatest rapidity and consequent economy of operation.
