Thisinvention relates to improvements in gas generators having among its objects the provision of a pluralityof annular compartments leading to a common chamber and having a valved carbureter provided with a plurality of battles, each communicating witli one of the said annularcompartments.' 4

Another object of the invention is to provide in a gas generator means for independent air supply to the lower end of a plurality of annular compartmentsand means for supplying steam to a chamber common to the said compartments. i

lhese and other objects will become more apparent from a consideration of the-accompanying drawing in. which like reference characters designatelike parts and in which Fig. 1 is a; sectional elevation of the improved apparatus. claimed herein; Fig.2 is 0 a top plan view of the same, the carbureting chamber being shown in section; Fig. 8 is a sectional plan view on a plane indicated by the line III,'III, Fig. 1 Fig. it is a sectional plan View on a plane indicated by the line 2 rv, 1v, Fig. 1.

In the practice ofthe invention the water generating chamber is provided with, a

central hollow shaft 2 and'the chamber and shaft are divided into a plurality of symmetrically arranged compartments designated respectively 1a,1b, 10, 1d,.and 2a, 2?), 2c, 265, by vertical walls. The partition walls in the chamber 1 do not extend to the top arch thus providing a common chamberA with which all of the compartmentsla, 1?), 10, and 1d communicate. The several compartments in the chamber and shaft are connected at points below. the grates 8 by a port 4-, controlled by a valve 5 operated bymeans of a rod 6 extending out through the walls of the chamber 1. Above the chamber 1 and in vertical alinement with the central shaft is arranged a carbureting shaft 7 dividedinto two compartments or chambers by a. diametrically arrangedwall 8 in'line vertically with, and forming-an extension of,one of the partition walls in the central shaft. The lower end of one of :the compartments in the carbureting shaft communicates with the commoncompartmentA of the chamber 1 through a. port 9, the passage of gases through said portbeing controlled by avalve 10. In order toinsure the thorough mixing of gases admitted to the carbureting column with the vaporized oil, introoluced into the stack 7 the pipe 11,a pluralityof'horizontally arranged baflies 12 are arranged in the compartments ofthe'stack, said compartments communicating one with the other through a port 13 in the'partition wall 8."

A plurality of openings 14,3ar

fed tothe several compartments 1a, 1b, .10, and 1d,;preferably by means of hopper and hell devices: '13 arranged in feeding relation 1 to said openings. These hopperfandbelldevices (only oneof which is shown) maybe of any'suitable construction-known in, the

art: i

In order to supply airffor purposes 1 5 inafter'described, to lower ends ofthe compartments 1a, 1b, 10, and-lcl,a*bustle pipe .15 suitably connected to a source of supply of airunder pressure, by apipe116, is connected by branches 17 provided with reguv e formed in -ithe top .of the chamber through'which coal is lating valves to the several compartments at points below the grates. Provision is made for introducing air into the common cham- :berA by means'of a branch pipe 18*extending from the supply pipe 16 to'lowe'r ends of one of the coal feeding hoppers:

In certainoperations hereinafter. d'escr'bed,

it isdesirable'to introduce steaminto the lower ends of the compartments, 1a, 1b, 10 and 1d,

also into the common chamber A, and provision is made for utilizing the heat contained .in the generated gasesfor the generation of steam for such purposes. As showninFig. 1, the lower portions of the compartment ofthe carbureting, shaft throughwhich the gases o descend, is provided with a port 19connected by 'a pipe 20 to the steam generatorof any suitable construction, whereby heat may be extracted from the gases and futilizedforthe is divided by a transverse Wall into the compartments21 and 22. pipeZO is -conrel nected to one of these compartments from which the hot gases will flow through the tubes 23 communicating with such compartment to the chamber 24 and from the latter through tubes communicating with the compartment 22. Steam is conducted by a pipe 25 toganannular: pipe 26 surrounding the I chamber I vand having valved-branches 27 ;e'scapeto the air.

communicating with the lower ends of the compartments 1a and 16. As shown in Fig 1,

the pipe 26 is provided witliavalvedddraneh- 28 extending into the air branch 18.

Airgwill now-flow up throughthexcharges in the compartments and the blast'gases generated therein willrpass into'thecommonrcompartment- A- and flow thence through the port 911p one-and down the'othersideof thecarbureting; column 7 through the pipe 20, the

tubes o'fithesteam" generator, from the latter, to and out through the stack-34: After'the charges in one 'or'more-of the compartments ofrthergasgenerator: havejbeen blasted up as described, the air is cut off? and .steam is admitted to the lower ends-of thecompartments through the branch pipes l? extending. from the bustle pipe '26 connected as: hereinbefore stated to thesteamgenerator; The water gas generatedzbythe flow of steam through. the incandescent charges: in the generator, will follow the coursehereinbefore described, but in lieuof permittingtlie combustible gases thus generated, to escape through" the" stack,

the-lid thereof: is closed'and such water: gases will flow through the 1 pipe;- 31,; through: the hydraulic seal 32-to a point of'useiorstorage. I fdesired,ithe gas may be enriched by i'njectingoil through thepipe 11 into the gasesrfiow ing throughthecarbureterZ.

t It will .be =understood thatif desiredvth e air blast-mgJotthe charge. in one: onmoresofathe compartments may be efi'ected While steam is being passed through other charges, which have been previously blasted. In such case, the lean gases produced in blasting will mingle with the richer gases flowing from'the other charges, but the lowering of the averageof such mixture can-be compensated for by theinjectionof oil as hereinbefore described. c

In lieu of the method described, steam, af terbl astihg'up, canbeadmitted to the common chamben Ai through the pipe 28 and the lower en'd'of hopper B so that the valve 10, .beingplosed,,andthe alve 5 at the lower end of the hollow shaft opened, the steam will flow" downwardly-through! the chambers in 10,16,1"0, and ld; and-rzupthrough the compartments-s2a,fl2b', 2c and2cl in the central shaft, andathence'rthrough :the pipe 20,:steam gener ator, pip'es 29 iand" to and through the hydrauliesea'lf In making this down run, the 'charges'inione' or more ofithe'compartment s 1a andilb 'canbefblasted up while gas is being" generated in. the: other compartment,

'ln or-dento' remove Water gas'or carbon ad heringt to Wallsof the chambersor passages, a nd lb'dgin'g behind projections or in corners, it is desirable fromtime totime to eiiect a return or'scavenging run, 2 In sucli"cases, the valves 5 controlling communication between the lo'wer ends otithe compartments in the water gas-generatorand the' central shaft are opened, and the valve 10 in port 9 and valves 3( )"and 20b in pipes 29 and 'lfiareclosed. Steam is admitted'into the'chamber 22 in the steam generatonthrough the pipe 36, and passes dowlr through some of the tubes of t'h'esteamj generatorand upthrough others to chamber 21 and then along pipe 20 to and I through the 'carbureting column andalso the compartments- 2a, 2b,-' 2c and 2d, in the central shaft From the'lower ends of the compartments t re How of steam and gases will beup througli the charges in the compartments 121 15, '1 0 'and 1d to the common chamber Aiand'yfrom that chamber by a pipe 37'to the'hydrauli'cse'ali The valve 38 in the pipewillbe'close'd exceptiwhenrmaking a return-0r scavengingrrunu a desirable method of;'operationicohsists in closing the valves. in" branches 17 'from the: bustle pipe, the valves-in branches 18 and 39 and valve20a; andiop'ening valve-20b and valves 5; atlowerend. ofcentral' shaft I 2. 4 willgtheni flow through pipes 16 and V 520 through carbureter 7 and down through making down runs it is preferred that the blasting up operations should be effected in succession in the several compartments 1a, 1b, as in this way, the hot gases formed in the blasting up can be utilized for further gasifying the coal and vaporizing the tars, and other by-products distilled from the coal charged into the other or gas-generating compartments.

As the surfaces in the carbureter and passages leading therefrom to the steam generator, may become heavily coated with carbon which can be removed onlyby combustion,- provision 1s made for lntroducmg a1r Into the pipe 20 by means of a branch pipe 39 extending from the supply pipe 18, and provided with a valve 40, and from the pipe 20 extends an outlet pipe ll having a controlling valve 42. During the scavenging run hereinbefore described, the valve 40 1s open to supply air for the combustion of carbon.

As the valve 10 in the passage connecting the common chamber A with the lower end of the stack is subjected to high temperatures,

especially during the blasting-up operation,-

provision is made for preventing excessive heating of the valve. A convenient construction to that end consists in providing apocket for the reception of the valve when raised 4 chi) and the air supply pipe 16 is connected by a valved branch pipe 39 to suchpocket.
