Referring to Figs. 1 and 2,1 generally indicates a closed casing providedwith the refractory and heat insulatinglining and enclosing the inclined, perforated wharf 5,

which positioned above the bottom of the casing so asto provide the space orcha'mber 4 beneath the wharf.

cThe wharf is preferably made up, offthe under lapping plates "5, havinginterstices between them forming passages leading from the space below the wharfto that; above.

I The casing is provided withthecharging opening 6 at the high end of theWh-arf, and

its gas tight closure 7, which in theap'paratus shown .is water sealed. he casing-is also provided with the discharge opening 8 atfthe low end. of the wharf, providedwith theflgas 4 "tight door or gate' 9'. Y

These flues communicate with the chamhere: below the'wharf, c r c The fire tube boiler o'r boilers areprefer bly, only partially enclosed within the casing and are shown thus in the apparatus chosen for illustration, whichindicatesthree 1 firetube boilersl2, their fire tubes'l3 communicating with the space ltabove thewharf and between the partitions.

- In operation, a charge of hot coke is ad I initted through the opening 6, the door 9fbedistributes itself in a quiescentlayer over the wharf. The opening, 6 is closed 'andthe fair within the apparatus is circulated and recir culated by the fan, throughthe wharf,'c0ke f f and boiler. After one or two passages through the coke the airv is spent by comb'us tion of asmall amount of coke and thef fur ther circulation is of these products are inert to the coke;

' During the p'assageof the gas throughthe coke, it" becomes heated thereby co'oling the V coke; and during its passage 'throughthe I boiler is becomes cooled, giving upfits heat, K

through the boiler tubes to the water to raise steam.- The recirculation is carried on until the'coke has'reached th e desired loiv'erltem- 'p'erature for dischargej The cokelisfalso cooled at the same-time by direct radiation to" 2 header 28.

chamber is somewhat enlarged as by the provision of the wall 29. There are also progas is terminated, the door 9 is opened'and the batch of coke slides gently down off the Wharf and out of the apparatus.

The fire tube boilers may be of standard type which can be manufactured economically. Moreover, they can be made inthe shop and shipped assembled, whichreduces the necessary construction in the field.

The apparatus is compact and simple,

economical of construction, efficient in operation and of high capacity. It combines the more economical construction of the fire tube boiler, with the high rate of cooling secured by combined recirculation of gas and direct radiation, and includes the gentle handling of the coke and low breeze production inherent in the wharf type cooler.

- The construction and mode of operation of the modification illustratedin Fig. 3 are as has been described 1n connectlon with F gs.

1 and 2 except that the chamber below the wharffis subdivided into two portions 23 and 24 by a partition 25 above which thewharfis provided with an imperforate intermediate portion 26*. The subdivision 23 of the chamber is connected with the fan by external connections 26, and the subdivision 24: of the chamber is connected with the fire tubes of the boiler, by an external connection 27 and a Atits discharge end the coke vided finger gates 30 which arerake-shaped structures having spaced upwardly projecting teeth. 1

In :use, assumingthe Wharf to be fully charged with coke, inert gas is circulated up- .ward' through the righthand portion and downward 7 through the lefthand portion. When the righthand portion is sufficiently cool, the finger gates are turned into the position shown and the righthand portion dis charged, then the lefthand portion is permitted to move toward the right by turning down the gates and a new batch of hot coke is introduced at the lefthand end. The obj ect of this is to maintain a uniform and continuous generationof steam. 1

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and arrangement and matters of. mere form without departing from the spirit of the invention which is not limited to such been cooled 'to the desired lower temperature, the circulation of matters or otherwise than the prior art and the appended claims may require.
