STEAM-GENERATING PLANT.

Application mea Maren 1e, 1917. serial no. 155,264.

To aZZ whom z' may concern.'

Be it known' that I, Josnrrr F. SPIEGEL, a citizenA of the United States of America, residing in the city of Toronto, county of York, Province of Gntario, Canada, have invented certain new anduseful Improvements in SteanrGenerating Plants, of which the following is a specification.

This invention relates particularly to means for firing locomotive and other boilers so that they will be smokeless in -operation, eiiicient and economical, silent and requiring a minimum` of attention fromfthe lireman. i i

I attain my objects by means of the constructions hereinafter described and illustrated in the accompanying drawings in which- Figure 1 is a longitudinal section showing a locomotive boiler arranged in accordance with my invention; 1

Fig. 1a shows the tender and its equipment and is complementary to Fig. 1;

Fig. 2 a cross section Iof the tender; an

Fig. 3 a front elevation of the tender.

In the drawings like numerals of reference indicate corresponding parts in the different figures. i

The drawings are to a considerablelextent diagrammatical and the mechanical constructions may be considerably varied with# out departing from the spirit of my invention.

1 is the boiler, which is shown as ofi the lire tube type and provided with a fluid burner, which is preferably, though not necessarily, with a jet 2 located oppositeeach firetulbe. These jets are each' preferably provided with a conical spreader 3 intended to produce a cylindrical jet of flame. Y

Each jet has amiXing chamber l located at its rear end, which mixing chambers com"- municate by means of pipes 5 with altcrnating air and gas conduits Gand 7 supported by a burner framet suitably supported close to the rear tube `plate of the boiler. Air is supplied to the air conduits by the `air pipe 42 connected to the conduits and supplied with `air by suitable compressing means, (not shown).

Gas is supplied from the supply pipe 8 Specification of LettersPatent.` n,

of the type shown and provided Patented Juiy 1,1919.

which connects with each gas conduit and leads from the producer gas generator 9` on the tender, whichygenerator is .hereinafter more specifically described.

In the gas supply pipe and also in the air supply pipe is located a manuallycontrollable valve 10, taneously controlled by asingle handle. In each pipe there is also provided an` automatic4 regulating valve l1 controllable by boiler, but as these art, they are not illussteam 'pressure `from the are we lllmown in the trated in detail.

y Thetender forms a feed water tank and the generator is arranged so that it is completely jacketed by the water in the tender, so that the waste heat from the generator is used to heat the feed water.

The generator is of the hopper type and is provided with sufficient gasspace 12 to give a small` reserve. The gas supply pipe communicates with this space and preferably forms a coil within the gas space. A further reserveltank 43 is preferably provided on top of the tender communicating with the gas space 12. n u

`The generator is provided at its lower end with a fire door 13 for re-lightingl, and a longnarrow door 14 through w ich the amined. 15 is the grate, of any ordinary both arranged to beisimultype, below which is located a suitable inclosed ash pan 16.V A pipe 17 leads into the ash pit for supplying steam and air to the generator. VViththis pipe connects a pipe 18, which will lead to anysuitable source of compressed air. f n `With the pipe 17 also communicates a pipe 19 from the boiler. The three pipes 17, `18 and 19 are each preferably provided with Ian automatic regulating valve `20 adapted to be cont-rolled thereto by the piping 441-; y

The feed ewater spaceof the `tender is connected by means of a pipe "21 with the boiler and an inspirator 22 or Othersuitable device by gas pressure `led 1s used inthis pipe to feed the water to the boiler. The exhaust steam pipe 23 from the valve chests of the locomotiveleads into the tender and its upper end isled into a condensing chamber 24:, which chamber at its lower end communicates by means of openings 25 With the Water space of the tender. A drainage cock 45 is preferably provided in the pipe 23.

At the lower .part `of. this condensingl chamber I provide a number of splash bars 26. These are preferably V-shaped as shown and slightly clear the bottom When hanging straight. Vhen slightly rocked they act elliciently as splash bars yand at the same timepermit of Water and sediment passing-y f'i'eelyunderneath' tlen When they are hanging straight. Y

A plurality of clean-out plugs 27 are preferafbly'V locatedl close toy the bottom of the Walls of the t'en'der.

TheA eoi'i'densi'ng"V chamber is provided at its upper end with? al safety valve 2S', preferably efk ther spring type; tolrelievey any eX- cessi pressure'- W-hieh might accumulatein thechamber. Aimanually operable'valve 29 is;` also. providedby means oft which any pressure may bei relieved and- Which may also beused toB allow any oilE that' mayi -colleet`^-` in tllecondensing chamber to flow out when rellngstheftender with water.

Y Into the Water space of the-tender extends theillin'gtube 30,- preferably frustoLconical as shown. Thelovver-end of thisl tube is foiiuuedvvithE a-valve seat-'engageable by the downwardly openingvalve' 31, the stem of which is suitably guided. This valve is normally' pressed to its=` seat" bythe coil spring 32 engaging ai supporting `4 frame Work' 33 andi the amdersideof theV valve;` This valve vvillff yield! to thel vveight of Water flowing downltliroug'h the filling' tube but will close to.` prevent'l egress of steamer Water.

Toiindieate" the pressure in the' Water tank I provide the pressure-gage 314i communicating Withi the Water'spaee. To indicate gas pressurefLprov-ide theipressure gage 35 communi'catin'g With the gas space 12. This gas space is alsofprovidedf with a Vsuitable safety valve 3.6. to Arelieve excess-.pressure A;z water gage-37 is. alsof preferably provided to indicate the water level in vthe tank.v

As the exhaust' steamy is no longer available to create-a draft,l=.provide mechanical means. in connection with the draftpipe 38 to create the necessary draft. For this purposelzemploy a fan 39iprojectin`g intoV the draft pipe anddrivenby asteam turbineror other: suitablexmotor`v supplied.. With steam fromqthe boiler.

hingeddamper 4'1. is. preferably pro.4 vided at the lovver end of the'draftfpipe and may be operatedbyany suitable mechanism.

The operation ofthe plant is .substautiall y as2 follows;V The generator isstarted in operationfandf suitably' supplied vvithl fuel and any yair and steam ynecessary to satisfactorily start'it in` operationmay be supplied from extraneous sources, after Which it will 4be suppliedy with steam from the boiler' and with air, as Lmay be necessary,from an air compressing plant provided for that purpose. As soon as gas is generated, it passes away under pressure through the supply pipe 8 andgis burned? at the jets 2, thus generating steam in the boiler, the products of combustion 'being drawn through the lire tubes preferably byY mechanically created draf-t as hereinbefore described.

The exhaust steam from the cylinders is ledto the condensing chamber and is there condensed, giving up its heat to the feed Water. Othervvisewaste heat from the generator is also taken up by the feed Water.

To conserve the heat of the feedl Water as mue-h as possible, the tender is preferably suitably lagged'. As may be necessary feed Water i's added through the filling tube 30 to'replace any Waste, and also as may be necessary oil accumulating iirtlie condensing chamber may be iloatedoif through the manually operable valve' 29;

The advantages of the constructions and arrangements I have above described are numerousbut' it Will: sufice to= enumerate a few of them. In operation the device will be` entirely smokeless,- as the gas generated is burnt under conditions which insure perfeet combustiom The loss of heatin the eX- haust byA radiationy from the irc box ini ordinary` locomotives or furnaces is almost en tirely avoided. The labors of the fireman are very considerably reducedas the generator is-self-feeding, and its hoppermay bemcchanically filled or emptied. VVitlrthis device almost any grade of fuelniay be used to advantage. v Perfect regulation of the firing can be= obtained automaticallyI and manually. The elimination' of the fireboxnot only strengthens the construction of the boiler as hereinbefore referred toybut permits of a considerable increase-of the-heating surface.:

It Will be understood, of course, ythat the detailsof the construction may be very considerably varied Without departiu g from the spirit of my invention.
