PROCESS OF GENERATING GAS. APPLICATION FILED JANJO, 1906.

m elbfil tort along both broad faces thereof. By this meansit is in some cases possible to insure a better application of the heat than where very thick masses are employed. 'lhestraw, as thus formed, is'then subjected to distillation by means of an apparatus suitenie for the purpose. 'In practice, a suitable conveyer l may be em loyed in order to conveniently transport t ebales from the press to said apperetus.

' This apparatus is adapted for the utilization of what has been found to be e. highly important principle, namely, that by 3730." gressively heating successive portions 0' the straw, beginning at that portion adjacent the discharge pipe, so that the volatilized prod note will pass through the incandescent solid,

carbonaceous skeleton preliminary to'their I means, which is here schematically shown as consisting of a plurality of burners 10, 11, 12, 13, 14 and 15, each provided with suitable regulating cocks in order that they may be brought into effective action in the desiredsequence, as will now be set forth. The basis of the distillation, that is to say, the bale of straw or the like, is so introduced into the retort as to be capable of being progressively subjected to the action. of the heat within successive zones 16, 17, 18, 19, 20 and 21 throughout the length. thereof by means of the aforesaid burners; the heating pro gressing from the discharge end. The fur uace may also be provided with baffle plates 22 for insuring a complete circulation of the heated gases around the retort, and an exit for the waste gases is shown by 23.

In carrying out this process in practice, it is to be understood that it is immaterial whether the straw be translated through the apparatus in order to subject successive portions of it to the zones of high tern iereture C: I L

the straw within the retort.

Whether the heated means he onus change so as to heat successive porti.

Thus, intermittent type of retort shown, ventiou furthermore contemolates the use an apparatus oi". a continu type so designed that the strmvmey be continuoi led through the retort and thereby obi. the desired effect.

The operation of the devise in carrying on the process is as follows: 1" -esh cl".

straw is introduced into the retort and-that burner 10-, which is nearest the escape con duit 8, is ignited, resulting ina carbonizing of zone 16 to a complete degree and, perha s, carbonizing the adjacent zone 17 to a relh tively less degree. .It will be noted in this connection that the gases from zone 17- are compelled to pass throughthe incandescent zone 16 before being enabled to esca e the re completely expelled and, at the same, time, the adjacent zone 18 will receive a similar rel ativcly incom lete heat treatment. The heat treatment will likewise be progressively carried out from the escapinge nd of the retort to the farther end, until no furtherfg generation otgaseous product is realized. It I will, of course, be understood that, in lieu of the single bale, a plurality of'bales may be employed and treated in sequence in the same manner as in the foregoing case, although it may be stated that such single bale will in many cases be preferred, the inven tion is not to be limitedin any respect to the manner in which the straw may be mtroduced into the retort, or the precise form of the same; thus, a pulverant mass may be cm- I ployed, if so desired, in carryingout the invention. I

In order that a suitable collectionof by- I products may be had and that such purification as may be desired may be made, a tarcondensing or receiving chamber 24 may be included in the course of the flow of the escaping products, and to separate out the more liquid products, commonly. known as pyroligneoup acid, acondensing coil 25 is. mclosed by a suitable water jacket .25 and is in connection at its lower end with a ccllec tion chamber 2'7, in order that the aforesaid fliquid products may accumulate therein. To

attains suiteble purification of the residual products, should this be deemed desirable, a number of chambers 28 and 29 containing limeprother suitable materialmay, be interposed, and to finally receive the valuable s, e large reservoir 30 will be positioned t the terminus of the escape conduit,

in commercially carrying out this invention, a plurality of retorts may be employed J and the carbonization may alternately take place throughout the series, the escaping gassous products being caused to pass through the iiicandesccnt mass in the last heated retort, which is maintained at a high temperature, and other variations in the manner of carrying out the process may be resorted to.
