Re: Feedwater Tank with no Pump

[Peter Trounce]

Steve,
It would work, but only if the tender tank is very well insulated.
The steam line will put steam into the tender where it will condense until
the tender and its water heat up to steam temperature.
Until then the tender will have a partial vacuum which will draw steam (and
water) back from the boiler.
And of course the tender water-level can only be the same as the boiler, at
best. So you cannot start with a full tender, or run it down to less than a
safe boiler level.
