WATER-OlL-GAS APPARATUS.

SPECIFICATION forming part of Letters Patent No. 526,364., dated September 18 1894. Application filed December 21, 1892. Serial No. 455.875. (No model.) Patented in England September 12, 1891, No. 15,469.

To aZZ whom it may concern.-

Be it known that I, HENRY FOURNESS, a subject of the Queen of Great Britain, residing at Manchester, in the county of Lancaster and Kingdom of England, have invented certain new and useful Improvements in Water- OiLGas Plants or Apparatus, (patented in Great Britain, No. 15,469, dated September 12, 1891,) of which the following is a specification.

The subject of my invention is a continuously acting plant for manufacturing lighting and heating gas composed of anadmixture of Water and oil gas, which plant is characterized by the particular arrangement of the fines and construction of the combustion chamber for utilizing the gas produced during the blowing-up of the coke in the generators for the purpose of heating the fixing retorts and the arrangement of the valves for controlling the continuous operation of the plant.

On the sheets of drawings appended hereto, Figure 1, shows a front view and Fig. 2, a side View of the plant; Fig. 3, a section through the fixing retort and combustion chamber; Figs. 4 and 5, front and side views of the retort months; Fig. 6, the arrangement of valve controlling apparatus in elevation partly sectioned; Fig. 7, a plan of the blower valves; Fig. 8, a sectional elevation of gas check valve, and Fig. 9 a sectional plan of gas distributing valve. Fig. 10 is a vertical cross section of the furnace.

The plant consists of two alternately working generators A, the retort chamber K with chimney, the steam boiler G, and oil cistern J and the necessary pipes and valves.

The generators A consist each as usual of a shell lined with firebrick and fitted with grate and ashpit closed by doors h, poke and peep-holes t', charging hole and cover j, and covers at the top on which the gas conveying elbow pipes at, a are mounted. These are formed with a vertical branch plugged by a counter-weighted plug 8 and. serve as peep and poke holes for the purpose of pushing a bar through the coke when the latter becomes clogged at the same time acting as safety valve in case an explosion should occur in the generator. At the lower end each generator is fitted with two tuyeres D (Figs. 6 and '7) each of which carries a steam jet blower D with an air inlet cock E. The pipe F leading from the boiler G, to the steam blowers, passes through the chimney and the tines leading to the same as shown on Fig. 2, and the steam is superheated thereby. The pipe F is connected to the branch pipes ff, leading to the steam jets D, each fitted with a stop valve f which however is kept open while the plant is in operation; the steam jet being kept on continuously while the plantis working, the air inlet being alternately opened for blowing the coke into incandescence and closed for the production of gas.

In order to assure the alternate working of the generators A, the four air cocks E are con, nected by wheel gearing, the wheels E on the cock spindles gearing with a wheel O on a vertical shaft (3 operated by a handle 0. The diameters of the wheels E and C are equal so that a quarter turn of the handle 0 turns the cooks a quarter turn and shuts or opens them.

The oil for gasification flows from thetcistern J, through the pipe r to a pipe '1', arranged over each generator, whence it drops through adjustable drip cocks into the oil cups d, 'fixed upon the top of siphon pipes making a hydrostatic seal, from which it en ters the generators near to their top ends as usual and falling upon the coke is gasified, the oil gas mixing with the water gas produced by blowing steam through the coke. When the heat of the coke has been reduced near to the lowest temperature required for the decomposition of the steam, the oil supply is stopped and the steam blast continued to clear the coke and generator of all residue of oil and oil gas before the air blast for reheating the coke is turnedon, whereby explosions in the generator are prevented. The gas produced is conducted through the elbow pipes a, a into the four way hydraulic valve box B. The latter is arranged similarly to hydraulic valves for controlling purifiers, and consists of a circular water tank B, Figs. 6 and 9, to which four elbow pipes, a a and o and b are fixed, extending upward into the tank B as shown. The pipes (1 a are connected to the pipes at, a on the generators respectively, pipe 0 to the pipe 0?, leading througha flue to the chimney, and the pipe b to the check valve b leading to the range of pipes b 1) (Figs. 1 and 2), extending over the fronts of the retorts e, and connected to them by the down pipes c.

The generator in which the coke is blown up by the air blast is placed in connection with the pipe 0 while the other generator, in which water gas is produced, is in connection with the pipes 19. This connection is effected and reversed by means of the bell valve B formed with a diametrical partition 13*, between the central tube B and the outside wall of bell B. This partition does not extend to the bottom edge of the bell but stops short a certain distance therefrom so that when the bell B is lifted up till the bottom edge of the partition is above the top of b is interposed.

the pipes (1- a 0, b, the edge of the bell B and tube B are still immersed in the water in the tank B. The bell can then be turned by a quarter turn and lowered again whereby the communication of the generator with the pipes 0 and b is reversed. In the position of the bell B, shown on the drawings, the water-oil gas from the left generator passes through pipes a b, to the pipes b and retorts, the air cocks E of the blowers for this generator being closed, and the combustion gas from the right generator, the air cocks E of which are open, passes through pipes a 0 to pipe 0 or chimney. For reversing the communications, the bell B is first lifted by means of the hand wheel 0 the boss of which is tapped with a screw thread and threaded upon the screwed part of the spindle 0 To the top plate B of the bell B a long tube B is fixed, which rests upon the boss of the hand whcel C so that when the latter is turned and screwed upward on the spindle C the bell B is lifted. The tube B is slotted in one part on both sides and a cotter O passing through the slots is fixed in the spindle C By giving the latter a quarter turn by means of the handle 0, the bell is turned to the same extent and after being lowered by the screwing back of the hand wh'eehthe communications are reversed, the pipe 0, now communicating with pipe 0, and pipe at with pipe I). The quarter turn of the handle 0 simultaneously reverses the cocks E, those on the left hand side being opened for admitting air to the left generator for blowing up the coke, and those on the right being closed for production of water gas in the right hand generator. By these means the inadverten-t mixing of the water oil gas from one generator with the combustion gas of the other, which would produce explosions, is prevented. As the lifting of the bell might draw water oil gas from the retorts through pipes b b, which mixing with the combustion gas might also cause explosions, the check valve This consists of a casing into the lower end of which the pipe 1) extends upward. The space between the casing and pipe contains water, in which the bottom edge of the bell b is immersed, the bell being attached to a rod 19 passing through a stuffing box at the top and attached to the chain 11 passing over guide pulleys. While the generators are working the bell is raised and the gas passes through the lateral branch I) of the casing to the pipes b and retorts. Previous to reversal of valve B the bell b is lowered and the return flow of gas from the retorts stopped, till the reversal has been effected, when the bell b is raised again. The top of the bell B is covered with water as shown, to cool the same.

The water oil gas passing into the retorts e is fixed therein as usual, and in order to enrich it and permit the continuation of the steam blast for clearing the generator from oil and oil gas as before described, during which a poor gas consisting mainly of water gas is produced, a second supply of oil is introduced into the retorts in a similar manner to that described in my British patent, No.15,469, of 1891. From the pipes a" descending from the oil cistern J another range of pipes r is branched off as shown on Fig. 2, leading to adjustable drip cocks over the oil cups (1. Two of such oil cups are arranged at the side of each retort mouth, as shown in detail by Figs. 4 and 5, on the top of siphon pipes for making a hydraulic seal, the oil pipes being connected to gas elbow pipes d inside the retorts. The oil introduced by these becomes gasified in the retorts and mixes with the gas produced in the generator, and a sufficiently powerful illuminating gas is thus produced while the supply of oil to the generators is shut off, for mixing with the gas previously produced without materially affecting its quality, and the use of heavy oils low in price is thereby rendered possible. Obviously the oil supply to the retorts may be stopped while that to the generator continues, if preferred, each supply being controlled by a single valve r and 0. From the retorts the gas is led by rising pipes k at the back end to the hydraulic main H, and through valves Z to the gas main m leading to the gas holder, the pipes 'n serving to draw off the tar, of which only a small quantity is however produced.

A further special feature of the plant is the arrangements for utilizing the combustion products, produced during the blowing up of the coke in the generators, for the purpose of assisting in heating the retorts and consuming the smoke from the retort fires. These combustion gases are as before described,.conducted from the generators through the valve chest B to the pipe 0' which leads to a flue 0 (Figs. 2 and 3) above the retorts, through which they can pass directly to the chimney Kwhen the damper p at the chimney end is opened and the damper 1& closed. When the former is closed and the latter opened, they pass down a fiue 0 at the side of the retort chamber into a series of horizontal tlues 0 where they become mixed with fresh air drawn through the inlets 0 into ascending t1 ues 0 communicating with fines 0 and issue from them into a narrow IIO passage 9 formed in the roof of the fire box of the retort fires. The latter consist as usual of two grates g g with stoke doors 9 and charging doors f. The fiame and smoke evolved from the fires ascend to the passage 9 where they meet the current of smoke gases from the generator issuing from flues 0 and another current of fresh air admitted through the inlets 9 into the flues g which also issue in the passage g The intermingled smoke and air thence passes into the combustion chamber 9 where they are completely burned and thence through openings into roof of the chamber 9 into the retort chamber. whence after circulating round the retorts they are conducted through the down fiuesf into the fluef 1eading to the chimney. The fiuesf are arranged on each side of the air flues o and g so that the air in these becomes heated before it reaches the combustion chamber and the fuel and heat are utilized in the best manner.
