A. A waste of oil only.
56. Q. What effect has leaks between firing valve and burner?
A. In addition to a loss of oil while fire is burning low, and but little steam atomizer being used, it interferes very materially with the engine's steaming by admitting air when using considerable steam atomizer. This causes a very irregular oil feed.
57. Q. What action of the fire would indicate leaks in pipes between firing valve and burner?
A. The fire-box will give off sounds similar to slight explosions, and the smoke at stack will indicate irregular fuel feeding.
58. Q. What would you consider the proper adjustment of burner?
A. That which will provide for the delivery of the oil from burner to flash wall without striking arch, side walls, or floor brick while doing so.
59. Q. In case it becomes necessary to fire up an oil burning engine with wood, what parts should be given particular attention?
A. The brick work. To see that same is not damaged or displaced while placing the wood in fire-box, also to protect by placing brick over that portion of burner extending into fire-box ahead of mud ring, or by so arranging the wood in fire-box as to prevent any great amount of heat from reaching the burner and melting nozzle of same.
60. Q. In case of sudden drop in steam pressure, what might be the cause?
