This invention relates to an auxiliary fuel oil heating system, particularly adapted'to beused as a system-for use on boarol ship or land for providingmeans to .insure a supply of. hot oil to any main steam generator when all conditions are in the state of `low temperature and no otherl suitable means exist for raising the temperature of fuel oil to the necessary degree in Vorder to venable the same toy be lighted. at ya burnerl beneath theymain boiler or. to be lighted at burners beneath a plurality of boilers.

The auxiliary Vfuel oil heating system of this invention contemplates the employment of an auxiliary heater consisting of a small boiler provided with the usual fittings, but containing in thesteamvand water space a coil or series of coils in which oil is inducted by means of a pump, and which oil ,ontaking up the temperature of the .steam andv water in which it is immersed,is 'fed by suitable means, such as a pump,.toa main burner. or series of main burners, through manifolds in a condition in which it can be burned. l In first starting up the auxiliary oil heating system the auxiliary heater is heated first by a small hand kerosene or light oil lamp, but after sufficient temperature has been imparted to the fuel oil in the coil and l oil line to the burners, the fuel oillitself can be burnediunder the auxiliary heater providing thereby a constant burner which is keptin use until the starting up of themain boiler has been Vaccomplished at which time the operation of the whole yauxiliary heating system is discontinued.

VThe invention consists in an auxiliary fuel oil heating system such as described in the following specification and particularly as `pointed out in the claims.

Referring to the drawings: i Figure 1 is a diagrammatic plan of my improved auxiliary fuel oil heating system.

10a66d `b6nea6h the man boilers and which operate in a manner well Aknown, to those skilled inthe Aart. 9 is an oil pump, 10 is a` fueloil storagetank, 11 is a strainer, 12 is an air vessel, 13 is a steam pressure gauge, 14 is a thermometer,'15 and 16 are mani.- folds, 17 is a coil through which the loil passes in being heated, the lower or inlet end 18 of the coil terminates infa pipe 19 which extends vertically upward throughthe interior of the coil and out through the, top 4 The pipe 19 is connected by a union 2O to a valve 21 and said valve is connected by pipes. 22, A23 and ,24`to the oil pump 9. The oil ypump 9 is v connected by a pipe 25 to the strainer 11 .and said strainer is connected by a

pipe

27 and 36 are 'controlled by valvesv 37, 38 and 39 respectively. The manifold 16"is` 'connectedby pipes40, 41 and 42 to the pipe25,

these pipes`f40, 41 and 42 constituting al recirculating line. A valve 43 is provided inV the pipe 40 whereby the recirculation line may be opened or closed. An` auxiliary burner 44 is provided for the auxiliary yboiler 5 andt-his auxiliary burneris connected by pipes 45` and`46toy the pipe 31. A `valve 47 is provided in the pipe 45 whereby `the burner v43 may be connected [with or ldisconnected from the 'pipe 31. Water is supplied to the auxiliary boiler'5 through the pipe 48 controlled by u a valve 50.` yA branch pipe 51 isconnected at one end thereofthrough the top of the boiler withthe steam space of the boiler Vand kthis pipe is provided with a valve 52. Whenp desired, the vpipe 51 `which constitutes an arm, can kbe swung from thepposition illustrated in fulllines, Figs. 3and 4, to the position illustrated in dotted lines, and cou# pled` to the `upperend ofthe pipe,19,and then uponopenin'g the valve5`2, steamfcan be `blown through the pipe 19,` the .coil 17 and thepipes and y fixtures connected therewith.V The boiler 5 is provided with'ythe usual wellsknown gauge -glass.53 and tit# l lo tings '54. The pump 9 may be.. operated by steam from the auxiliary boiler 5 conveyed thereto through

pipes

55 and 56,'the ex` haust steam being conveyed away from'tlie. pump by a pipey 57,4or anypother well-known` power means may be provided to operate said pump. A valve 58 is provided inthe pipe 55 to control the admission of steam to the pump.V r1`he manif-old15 is provided with a waste pipe 59 which is provided with a valve 60 and the manifold 16 is 'provided withfa waste pipe 61, controlled by a valve 62;, y f

The general operation kof the apparatus hereinbefore specifically described is asv follows z-Assuming the entire' system to be cold and that it is ydesired to generate steam in the main boilers, or yany 'of them, the auxiliary boiler 5 has water therein in which a coil17 is immersed. -The coil 17 yis supplied Vwith oil'from the fuel storage tank 'by means of the pump 9 which draws' the oil from the storage supply tank through the pipe 27, strainer 11 and pipe 25 and forces-it through

thepipes

24, 23, 22 and 19 -to they bottom of the coil 17, this constituting'the oil supply.v The water in the boiler is at first heated by'means of a'hand lamp .and when 'the water in the boiler` 5 'becomes sufliciently heated to produce steam and lsufiicient pressure and heat to raise the temperaturelin the coil 17 toabout 240, then the oil iii said coil1 passes from thegcoil through the pipe 28 to the manifold 15 and from the manifold through

pipes

31, 32 and 33 to the'manifold 16. From the bis manifold 16 the oil passes to the

burners

6, 7 and 8 under the main boilers, or to any one of them, thefpassage of oil through the pipes 34, 35 and 36Lto the burners 6, 7V and v8 respectively being controlled by the valves 37, 38 and39 respectively in the manifold 16 i the coil 17 through

vthe manifolds

15 and 16 and the pipes connected therewith before it arrivesat a temperature of 240, and in such Acases if the, oil is not sufficiently heated for the purpose of burning freely under the boilers, it is recirculat'ed by vclosing the valves 37, 38 .and 39,l opening ,the valve 43 andallowing the oil to circulate through the

vpipes

40, 41, 42 and 25 through the 4.pump

9 and from the pump through the pipes 22,

23 and 24 back tothe coil 17.A This 'recirf culating of the oil may be continued as long y as maybe desired.

As soon as the water-and'steam have been "sufficiently heated to start the roil ini circulation as hereinbefore'describedfthen .the hand burner maybe replaced by the vburner 44 which is suplied with oilthrough lthe pipes 45 andy 46 from'the pipe 31, the Voil being turned on to or oil' from the burner 44 by means of the -.valve"47. The pump is v.If desired, the oil may be circulated from' operated by steam from the yauxiliaryV boiler supplied thereto by pipes and 56 governed v by the valve 58.

In addition to using the steam for operating the pump 9 and for'heating the oil, the system of piping hereinbefore described iny' lcludingk the coil maybe blown out by the steam andk this is accomplished by swingying the pipe arm 51y from the position illus- Vtrated in full'lines, Figs. 3 and 4,(to that will also drive the oil through thecoil 17,

pipe 28,inanifold 15, pipesSO, 31,' y32 and 33 out of the manifold 16fandpipes leading therefrom to the mainburners.` The steam maybe utilized .to drive the oil .out of the

pipes

40, 41, and 42, and, in fact, by'means of the steam and the connection 51 from the vboiler to the oil'piping system the oil can` be driven outof the entire oil piping system strainer. 4 1I claim: c
