(2) Economy in handling fuel. Oil can be run intotank on tender from standpipe, same as water, and sup-plied to firebox by turning a valve always within fire-mans reach.

Esti-mated as at least 50 per cent less than the cost of handlingcoal-burners. (5) Diminished repairs to locomotives, especially fire-box repairs. It is only fair to note that in the case ofoil-burning locomotives the firebox and flues are subjectedto very severe punishment, and it is exceptional when. Figure 223a. Details of Oil-Burning Furnace. an engine will run two years without renewing firebox,or longer than twelve months with a set of flues. It isalmost useless to attempt to patch side-sheets, for theheat is so intense that the extra thickness of metal pre-vents the heat from being taken up by the water, andthe patch is soon burned. The side sheets in an oil-burnercrack most frequently immediately back of the arch, evi- 474f LOCOMOTIVE ENGINEERING dently because of the heat being most intense at that partof the firebox. (6) Economy in cleaning engines, due to absence ofsmoke and cinders around engine. (7) Less waste of steam at safety valve. It is esti-mated that in ordinary locomotive practice the waste ofsteam at the safety valve (which is equivalent to a wasteof fuel) is about 5 per cent; but on an oil-burning loco
