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.
