Thanks, John, for clarifying the relative merits of Elesco vs. Worthington
BL feedwater heaters. Can you or anyone extend this thread and tell us a
little about the Coffin units? I'm curious because, to my knowledge, the
Burlington had only three engines equipped with feedwater heaters of that
type (all Ottumwa Division O-3s), and those units all were removed from the
engines relatively early. Why were they so unsuccessful?
A related (sort of) question: Can you explain the difference between
"lifting" and "non-lifting" injectors, and tell us why the Burlington seems
to have had so strong a preference for the latter?
Thanks again,
Jonathan
