PIERRE PLANTINGA, OF CLEVELAND OHIO; THE CLEVELAND TRUST COMPANY EXECUTOR OF SAID PIERRE PLANTINGA, DECEASED.

CARBONIZING AND GAS-MAKING APPARATUS.

Application 'filed December 21, 1922. Serial No. 608,203.

My invention relates to carbonizers used in gas-making apparatus, its object being to Drdvide a device of said character which is simple in construction and efficient in its oporation.

The said invention consists of meanshereinafter fully described and particularly set forth in the claims. V

More specifically, my said invention consists of a modified form ofthe apparatus shown, described and claimedlin my =appl1cation Serial No. 601,680, filed November 18, 1922 a n In the annexed drawing, the figure represents, diagrammatically,a side elevation of :r carbonizer embodying my invention.

In the illustrated embodiment of said invention, a gas-producer 1, is provided of the usual construction, having a primary alrinlet 2 and a steam-inlet 3, at the bottom, and a secondary air-inlet 4 at the top so that the gas may be burned in such top, which forms a combustion chamber. Above the producer is an open arch 5 which supports checkerwork (i which fills a heat-absorbing and transmitting element 7.

The top part of the producer, that is the combustion chamber, communicates with the bottom portion of a ca-rbonizing chamber 8 through the medium of a pipe-conneet1on 9 and the top portion of the said carbonizer is connected with the inlet side of a blower or fan 10, by means of a pipe-connection 11. The outlet side of said blower is connected with the top portion of the element 7 by means of a pipe-connection 12 controlled by a. valve 13. A branch 1-1 leads from the connection 12 to other parts of the gas-making apparatus (not shown) as will be readily understood by those skilled in the art.

The top of the carbonizing chamber is pro vided with a charging inlet 15 and closure 16 therefor as shown, and the bottom with a discharging outlet 17 and a suitable closure 18.

The top of the element 7 is provided with an outlet 19 controlled by a suitable stackvalve 20 below the stack 21.

Intermediately of the blower 10 and the branch pipe 14 is a valve 22.

In operating the above described appara tus. assuming that the producer 1 is charged with burning fuel and the carbonizer charged with coal, the valves 13'and 22 are closed and the stack-valve 20 opened; primary air and the required amount of steam duccr combustion chamber of the producer. The

and the stack valve 20 closed.

are admitted to the producer through the inlets 2 and 3 and producer gas is thereby generated by the producer 1. Secondary air is admitted through the inlet t and t e progas is \burned in the top portion or gases oil-combustion rise, pass through the whecker-work '6, impart their heat thereto and thenrpass' out through the opening 19 -into the 'stack'21.

Vhen. the checker-work is sufficiently heat'ed,;the primary and secondary air and steam are turned ofi',

valves

13 and 22 opened The blower is then started and the gaseous content of the apparatus is -'caused to circulate through same. Such gases. in passing through the checker-work become highly heated and then pass in to-the-bottomlof the carbonizer, upwardly through the coal therein. These hot gases distil such coal with a resultant pro duction of coal gas which passes with such heated gas out through pipe 11, through blower 10, pipe connection 12 and back into the element 7.

superfluous gas passes out through the branch pipe 14.

The above described process continues until the temperature of the checker-work 6 is below that required to impart a distilling temperature to the gases, whereupon the blower is shut off,

valves

13 and 22 closed, and stack-valve 20 opened.

The primary and secondary air and steam are again turned on, the checker-work reheated as before, and the previously dcscribed subsequent procedure carried out.

By means of the above described apparatus gases of various kinds may be obtained.

During the process of distillation, the primary air and steam may be cut off and only coal gas produced. By turning on the primary air and the required amount of steam, a mixture of coal-gas and producer gas may be obtained. By turning on the primary air and more steam a mixture of coal-gas, producer gas and water gas may be had. By shutting off the primary air and passing steam only through the producer, a mixture of blue water-gas and coal-gas is secured.

These different gases may therefore be produced and if it is desired to segregate any one or more of them, they may be conducted to suitable separate receivers, as will be understood by those skilled in the art.

It will be understood that a continuous operation of the producer forthe purposeof supplying gas to be burned for generating heat to heat the checker-Work, may be obtained by adding one or more elements 7 and suitable valve-controlled connections, as is shown and described in my above-mentioned pending application.

'hat I claim is:

1. A carbonizing and gas-making apparatus comprising a heat-absorbing and transmitting element; heat-generating 'means including a gas-producer, beneath and connected with said element; a primary-air inlet for the lower part of the producer and separate means for admitting steam to such producer part; a secondary air inlet for the upper partof said producer; a carbonizing chamber separate from said producer and said element but communicating with both of same; and means for effecting a circulation of gases-through saidelementand ear bonizing chamber.

2. A carbonizing and gas-making-apparatus comprising a heat-absorbing and-transmitting element; heat-generating-means including a *gas-producer, beneath and connected with said element; an air inlet forthe lower art of said produc'er'a'nd separate means for admitting steam to such producer said chamber;

part; acarbonizing chamber separate from said producer and element; means establishing communication between the upper part of said carbonizing chamber and the upper part 'of said element; means establishing communication between the lower part of said chamber and the lower part of said element; and a blower in the first-mentioned communicating means for efi ecting a cyclic circulation through and between the said 'elementand carbonizing chamber.

3. A-carbonizing and gas-making apparatus comprising a heat-absorbing and transmit-ting clement;a-gas-producer below said element and having its bottom communicating with the 'top of said producer, the latte'r being'provided with the usual primary-air and steam inlets and also provided at the top part thereof with a secondary-air inlet; a carbon'izing chamber separate from:

the said producer and element; a conduit connecting the bottom of said chamber with the top of said producer; a conduit connecting-the top of said'element with the top of conduits for, efiectin a cyclic-circulation of gas'cs through said element and chamber.
