PROCE$S OF MANUFACTURING GAS.

SEECIPICAI'ION forming part of Letters Patent No. 334,701, dated January 19, 1886,

Application filed September 29, lB5. Serial No. 178,594. (No model.)

To all whom, it mag concern:

Be it known that l, ARTHUR O. GRANGER, of the cit-y and county of Philadelphia, and

' State of Pennsylvania, have invented an Improvement in the Process of Manufacturing Gas,of which the following is a specification.

My invention has reference to processes for the manufacture of gas; and it consists in first passing the products of combustion from a water-gas generator heated by direct internal combustion through one set of flues of a superheater having two sets of dues, heating said superheater, and raising the carbon of a generator to incandescence by said internal combustion, then passingthe water-gas produced in said generator by the decomposition of steam through the other set of lines in the superheater; and it further consists in first passing theproducts of combustion from a watergas generator heated by direct internal combustion through one set of fines of a superheater having two sets of flues, heating said superheater,and raising the carbon of the generator to incandescence by said internal combustion, then passing the water-gas produced in said generator by the decomposition of steam, alter being admixed with a hydrocarbon fluid or vapor, through the other set of fines in the superheater, all of which is fully set forth in the following specification, and shown in the accompanying drawings, which form part thereof.

The nearest approach to my improved pro cessis shown in the Patent to Rew, No. 290.930, ofl883, and Langdon, No. 263,921, ofl882; but these patents are for processes widely differing from mine in the main features. Rew shows an apparatus in which the process of generating watergasis continuous and in which there is no step for heating up the contents of the generator worked alternately with the generator of water-gas, and, further, all of the products from the generator pass th rough the same set of flues, which tlues are heated externally by gas otherwise produced. Langdons apparatus is simply to produce a greater quantity ofa heating-gas, part of which is used to continuously heat regenerators through which steam is passed and superheated before being fed to the producer. Both these patents, however, are devoid of the alternative process of heating up and generating gas, and in which the products from the hcating'process are used to heat a set of lines or chambers by external combustion, and through which fines or chambers the gas generated as the secondary step is caused to pass.

The object of my invention is to cause the products of combustion fronha gas-generator to pass around the outside of superheating or fixing fines of fire-brick or other refractory material, whereby they are heated and by which the water-gas, after being carbureted, is fixed or made permanent by being caused to pass through the said externally-heated does. This method of working enables the illuminating gas to be rendered fixed or'permanent with all the effects of the former method of heating the fixing-chamber by internal combustion, and with none of the disadvantages thereto due to clogging or filling up of the passages or lines from the products of combustion when heating up. The walls of the fiues being comparatively thin, and the heat on the outside thereof being very intense, the fire-brick becomes heated to incandescence, and, when subsequently the water-gas, after being carburetel, is passed through the said flues, the heat thereof fixes the gas, making it permanent.

In the drawings, Figure 1 is a sectional elevation ofa water-gas apparatus embodying my invention, and Fig. 2 is a plan view of the airdistributing nozzle removed from the bottom of the generator.

A is the generator. Bis the superheater. The generator may be made in any of the wellknown manners, being provided with the grate O and the ash-pit D. Surrounding the ashpit is placed a circular blast-nozzle E. This nozzle is made in the form of a box, and is provided with a large number of small apertures, e, opening under thegrate, and by which air is finely divided and allowed to strike the under surface of the grate with an even distribution, thus causing a more perfect combustion and less liability to mechanical disturbance than when a simple large blast orifice or opening is used.

F is the air-supply pipe, and the blast is controlled by a suitable valve.

G is the steam-nozzle for admitting steam under the grate-bars.

Superheater B is provided with alower com ICO bustion-chamber, K, having an arched roof, J, which roof supports the filling H, consisting, preferably, of vertical tubes or passages opening into the chamber K, through the root thereof. ThesefiXing-fluesHarepreferably formed of fire-brick or other refractory material, and the spaces I between them form a heating-flue. The chamber K and the spaces or fiues I are connected with the generator by fines N and N, respectively, either one of which may be closed by a valve, 0.

Lis a hydrocarbon nozzle for admitting fluid hydrocarbon or other carbureting medium to the water-gas prior to its passage through the super-heater.

M is a blast-pipe for admitting air to the heating fine or space I.

P is the gas-outlet from the top of the superheater and leads to the washer.

It is the chimncyfiue, and is provided, as usual, with a suitable valve.

The operation is as follows: A fire being built in the generator, air is admitted by pipe F, and the products of combustion from the coal contained therein are caused to pass through line N, and are burned in the space or line around the fixing-fines H, raising them to incandcscence and passing off by chimney R. When the superheater is heated and the coal in the generator has been raised to incandescence, the blast from pipe F is shut off, valve R closed, blast from pipe M shut off, steam from pipe G admitted to the bottom of the generator, and hydrocarbon from nozzle L turned on. Now, the water-gas produced in the gen erator passes through fine Ninto chamber K, where it mixes with hydrocarbon fluid, either in the liquid or highly-subdivided condition, by spraying or being previously vaporized, and the carbureted water gas so produced passes up through the tines H, becoming fixed and ultimately pass off by the pipe P of the washer to holder.

\Vhile the construction shown is simple, it is evident that the details thereof maybe modifiedin various ways without departing from my invention.

Having now described my invention,what[ claim as new, and desire to secure by Letters Patent, is

1. The herein-described process,which consists in first passing the products of combustion from a water-gas generator heated by direct internal combustion through one set of fines of asuperheater having two sets of lines, heating said superheater and raising the carbon of the generator to incandescence by said internal combustion, then passing the water gas produced in said generator by the decomposition of steam through the other set of ll nes in the superl1eater,fixing the gas without bri nging it into contact with any deleterious products or deposits from the generator produced when heating up, the said steps of heating up and producing water-gas in the generator being carried on alternately and independently of each other, substantially as and for the purpose specified.

2. The herein-described process, which consists in first passing the products of combustion from a water-gas generator heated by direct internal combustion through one set of fines of a superheater having two sets of fines, heating said superheater and raising the carbon of the generator to ineandescencc by said internal combustion, then passing the watergas produced in said generator by the decomposition of steam after being admixed with a hydrocarbon fluid or vapor through the other set of fines in the snperheater, fixing the gas without bringing it into contact with any deleterious products or deposits from the generator produced when heating up, the said steps of heating up and producing water-gas in the generator being carried on alternately and independently of each other, substantially as and for the purpose specified.

In testimonyof which invention 1 hereunto set my hand.
