APPARATUS FOR MAKING COKE AND GAS.

SPECIFICATION forming part of Letters Patent No. 436,882, dated September 23, 18910.

Application tiled February 2, 1888. Serial No 262,695. (No model.)l

To all whom t may concern:

Be it known that I, CHARLES NEWBOLD TRUMP, a'fcitizen of the United States, residing at Wilmington, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Apparatus for Making Coke and Gas, of which the following is a specification.

My inventionrelates to an improved arrangement and combination of appliances for making coke and of conserving the rich hydrocarbon gases given off from the coal being coked.

Heretofore coking-ovens have chiefly been heated by burning the rich gases d riven off from the coal in the process of coke-making in the tops of bee-hive `ovens or in the furnaces and flues of the so-called Belgian coke-ovens.

The principal object of my present invention is to reduce the cost of production of coke, gas, and other products of the destructive distillation of coal by substituting cheaply made water and producer gas, or a mixture of them,fortherichhydrocarbongasesheretofore burned in heating coking-ovens by introducing said gas from the producer or generator in a heated condition directly into the furnace andiiues of said coking-ovens and burning it, thereby materially economizing in fuel and conserving the rich hydrocarbon gases given off from the coal being coked for adinixture with natural gas or other fuel gases, in order to impart to them the characteristic odor of coal-gas, and also affording additional heat-giving properties.

The characteristic features of my invention will be more fully understood from the following description, taken in connection with the accompanying drawing, showing, artly in section and partly in elevation, a plant of my improved construction.

Referring to the drawing, C C are the cokeovens.

Ais the gas-producer; B, the regenerator; F, the cooler, and G the scrubber.

The gas-connections and details will be hereinafter described.

The gas-producer A may be any of the wellknown forms of producer or water gas generators. Preference, however, is given to a Taylor producer provided with a revolving bottom. i y

The coke-oven C may be of either the Carves, Appolt, or bee-hive forms.

The coke-oven shown is of the Simon-'Oarves type, inwh-ich the air to support combustion in the furnace and flues is drawn through a duct in contact with the iues for conducting the escaping products of combustion.

The operation of the apparatus is as follows: A fire is started in the producer or generator A, and anthracite, buckwheat coal, culm, or other fuel charged in until a sufficient quantity is had therein. Air is forced in through the pipe d by a jet of steam, and the resultant gases, being a mixture of producer and water gas, conveyed by pipes a and a, which are preferably covered with suitable material to retain the initial heat, to the furnace of the coke-oven ,0, where they are ignited by lire previously started on the grate of the furnace. Air heated by the escaping products of combustion is supplied to burn the gas or gases in the furnace and fines of the oven, as is well understood in the practice of the Simon-(larves system.

The coke-oven C is provided with a furnace C2 and with apipe a', leading from the gas producer or generator into the furnace of said oven. When sufficiently heated, the coke-oven is charged through openings, as C8, in the top thereof, the coal leveled, and all openings properly closed and luted.

When beehive or rectangular shaped ovens with bottom iiues (through which the rich gases are exhausted, as in Jammisons system of coke-making,) are used, the producer or water gas from the producer or generator A would be conducted to the tops of the ovens and burned above the surface of the coal evenly spread onto the bottom. After coking is complete the charge may be raked out and quenched.

In the drawing is shown a system which is especially adapted for use when bituminous coal is availed of, and in which by-products, as ammoniacal liquor and tar, are to be separated from the gas generated in the producer A.

The operation is as follows: The producer or generator A being charged and the charge IOO ignited, air is forced through the pipe d by a jet of superheated steam, and the resultant gases passing through the regenerator B, the cooler F, scrubber G, and thepipes, as shown, deposit ammoniacal liquor and tar, which are lead to proper receptacles. From the outlets of the scrubber G suitable pipes g, 71, j, and 7c are provided to conduct the cooled gases either to a purifier and gas-holder (not shown) or to the base of the regenerator B. As the gas flows through the regenerator B around the zigzag pipes through which the hot gases from the producer or generator A are passing, it takes up a large proportion of the inl itial heat, conveying it through the pipes*v a and a2 to the furnace of the coke-ovens C C, Where the gas burns more rapidly than if not heated. In fact, producer gases do not easily ignite if cold.

The great merit of the arrangement of apparatus as hereinbefore described is that most jects of my invention, what I claim as new,

and desire to secure by Letters Patent, is=- The combination of a gas-generator, a cokeoven, a regenerator, a cooler, a scrubber, and

'gas-connections extending from the generator through the regenerator, cooler, and scrubber, and back through the regenerator to the furnace of the coke-oven,substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
