Fig. 11.—Boiler furnace arranged for burning oil. Steam enters the opening (e, PL VIII, A and B) and flows throughthe conical opening (f), regulated by the hand wheel (g), to meet theoil as the latter falls between the vertical flanges (h, B). A third opening (i, A and B) in the burner draws air from theback of the furnace through a fire-brick duct built on top of thegrate and connecting with the bottom side of the latter at its rear,while the front end communicates with the iron pipe (M, fig. 10) con-nected to both burners. A mixture of steam, oil, and heated air is therefore blown out ofthe burner, and this is joined by the main current of air flowing uparound the front end of the grate bars, somewhat heated by its passagealong the under side of the grate. The oil was stored in an iron tank (A, fig. 10), 7 feet in diameteby 5 feet deep, sunk in the ground, into which the oil is emptie

A steam pump (B, fig. 10) drew oil from the tank through thestrainer (IT, fig. 10) to the burners under a head of about 10 feet. The pump was run constantly and delivered a surplus, which flowedback to the tank through the pipe (T, fig. 10). The oil was provided with a device- (D, fig. 10) having a pistonconnecting by a chain with a cock (S, fig. 10), which automaticallyopened when the boiler was not under steam pressure, so that thestandpipe would be emptied of oil by the latter flowing to the storagetank, The steam exhaust of the pump passed through the tank by thepipe (Z, fig. 3 0) and thence to the atmosphere. Thereby high coldtest oil is kept sufficiently fluid in cold Aveather to flow freely into thestrainer, but is not sensibly heated to the touch when it arrives atthe burner. The air entered the ash-pit tiles und
