L'olio viene lasciato depositare nel tankfor un tempo per sbarazzarsi dell'acqua che si trova sempre in quantità minore o maggiore nell'olio. Dopo che l'acqua è stata scaricata, l'olio fluisce dal serbatoio alla tubazione principale e nei serbatoi di stoccaggio dei clienti. Quando l'olio è stato suggerito per la prima volta come possibile combustibile, era consuetudine alimentarlo alle caldaie per gravità da tubi di supporto o serbatoi elevateddentro o vicino al locale caldaia, ma questo si è incontrato

. The street railway review . rom the Texas fields in tanksteamers, from which it is pumped into a 55.000-barrel elevated tankon the dock at New Orleans. The oil is allowed to settle in the tankfor a time in order to get rid of the water that is always found inmore or less quantity in the oil. After the water is drained outthe oil flows from the tank to the main pipe line and into thesmall storage tanks of the customers. When oil was first suggested as a possible fuel it was customaryto feed it to the boilers by gravity from stand pipes or elevatedtanks in or near the boiler room, but this method has been largelyabandoned owing to the objection of the fire underwriters to thestoring of quantities of oil above the grate level of the burners. At the Claiborne station the oil is again allowed to settle for twoor three days in the buried tanks before it is fed to the boilers, onetank being used while the other is settling. The oil is drawn fromthese reservoirs by two suction pumps which feed the fuel to the HQKT XII. IIX AVO STEAM PRESSURE DIAGRAM II. IIRi: KEW ORLEANS. burners at about 45 lb.

The boilers wereoriginally fitted with Ilawley down-draft furnaces and these werenot removed when the oil apparatus was installed. The burners arc known as the Von Phul pattern which employs live steam as the medium for spraying the oil. The burner is made entirely of brass and comprises a J^-in. pipe within a J4-in. pipe, the smaller pipe being for oil and the larger one for steam. The tip of the oil pipe enters the tip of the surrounding steam pipe and as the oil flows out in a small stream
