ARTHUR O. GRANGER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE UNITED GAS IMPROVEMENT COMPANY, OF SAME PLACE.

.PROCESS 0F MANUFACTURING GAS.

SPECIFICATION forming part of Letters Patent N o. 418,711, dated January '7, 1890.

Application filed June 2,1885. Serial No. 167,384. (No model.)

To @ZZ whom, it may concern:

Be it known that I, ARTHUR O. GRANGEE, of the city 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 toa process for the manufacture of water-gas; and it consists in first heating up a bed of carbon in a generator, and with the products of combustion therefrom heating up a superheater or fixingchamber by internal combustion, then passing steam into the bed of carbon-producing water-gas, then passing the water-gas mixed with carbureting-luid through the superheater, entering at the end where it is least hot, and causing it to pass through the superheater, gradually entering a zone of greater temperature, until it nally escapes t0 the washer or holder from the end which is hottest, as is fully set forth in the following specification and referred to in the claim.

The object of my invention is to insure the illuminating-gas passing into the superheater at the least hot portion' and leaving the same at its hottest part, by which the thorough decomposition and xin g of the gases resu1t,and at the same time the production of lamp-black is entirely overcome. `In apparatus in which the hydrocarbon vapors or liquids are caused to enter the superheater at its hottest portion part of the hydrocarbon is instantly converted into lamp-black and fixed upon the filling or lining of the superheater. By overcoming this production of lamp-black I greatly increase the production of illuminating-gas, as Well as improve the working of the apparatus.

In the drawing is shown asectional elevation of water-gas apparatus in which to carry out my improved process.

His a superheater, and G is a generator, whlch are connected together in any suitable manner, as by the connecting flue or passageway E, which opens from the top ofthe generator into the bottom ofthe superheater, or by an auxiliary flue connect-ingwith the upper part of the said superheater. The generator is provided, as usual, with the blastpipe I and the steam-pipe J, preferably entering below the grate-bars.

The superheater H is provided with a lower combustion-chamber K and auxiliary flue C, connecting the flue E with therupper part of the said superheater and above the filling I. A is a Water-cooled Valve and works 4on the water-cooled seat B, and is adapted to close the entrance to thechamber K or the flue C, by which the product from the generator may be caused to pass either into ,the chamber K or the flue C, as desired, thuscausing the said products to pass into the top or bottom of the superheater.

L is the smoke-outlet opening from the top vof the superheater, and F is the gas-outlet opening from the chamber K and connecting with the usual Water seal or Washer.

D is the hydrocarbon-spraying nozzle, which admits hydrocarbon fluid into the upper part of the superheater, preferably where the water-gas, which passes through the flue C, enters the superheater. If desired, the iuid hydrocarbon may be admitted anywhere in the iiue C or in the su perheater proper, or it might be admitted in the generator. Y

In making gas the valve A is turned up, so

as to close the iiue C and open the passage- Way from the generator into the bottom of the superheater or its chamber K. The smokeoutlet L is opened and the blast from pipe I is turned on. The coal in the generator is brought to incandescence by the blast from the pipe I, and the products are caused to pass into the chamber K and are burned therein, the products therefrom passing up through the iilling or internal brick-Work of the superheater. and escaping. by the chimney-outlet. The airblast from pipe I is then shut oif, chimney Lis closed, and valve A turned so as to close the entrance to the chamber K from passes off by ilue F through the usual Water seal to the holder, if desired, preferably passing through purifying apparatus before reaching the said holder.

If desired, the auxiliary flue C might be separate and distinct from the superheater and built in the form of an external tube, and in place of one valve A two valves may bet used, one controlling the entrance to the bottom of the superheater or chamber K, and

,location may be given to the gas-outlet or the steam and blast pipes.

In this application I do not claim the apparatus, as that forms subject-matter of an application of mine filed January 9, 1885, Scrial No. 152,385.

Having now described my invent-ion, what I t claim as new, and desire to secure by Letters Patent, is-

The process of manufacturing gasA which 1 consists in raising abody of carbonaceous material to a high degree of heat by burning it with air, and at the same time burning the gaseous products of combustion With air and highly heating a body of refractory material, then suspending the combustion and introducing directly into the coolest portion of the heated refractory material hydrocarbon liquid, causing it to pass through the refractory material in a direction the reverse of that in which the products 'of combustion passed through during the process of heating, then at the same time causing steam to pass through the highly-heated carbonaceous material and be decomposed into carbonio oxide and hydrol gen gas, then causing'such gas asfast as it is generated to pass through the refractory mal terial in the same direction and in company i with thehydrocarbon liquid, and thereby combine with the vapors and gases of the hydrocarbon as they are generated by contact of the oil with the refractory material at successively increasing temperatures.

In testimony of which inventionI hereunto f set my hand.
