Sorry, forgot the separator question.
It's a small vessel that the ends of the coil are connected to. The heat
boils the water in the coil, the steam rises to the separator, the steam is
taken from the top of the separator and the water continues to circulate
through the coil. If you are serious about building this, you'd better do
some more research. Its a little more complicated that the usual tea kettle.
Designs have evolved since the 1700"so best practice these days is pretty
sophisticated.
During the industrial revolution in England there was an average of one
steam explosion per day until the invention of the dead weight safety valve!

Hi,

Thanks for the reply,

This is the first I've heard of a "seperator". Do
you have links or pics?

Also, what is the recommended material for
the "boiler coil" ? Recommended method
of bending it?

Thanks!

Rich


Pick up a couple of old Audel's books, the one for powerplant engineer
is good and covers a heap of detail on steam. As with anything, if you
go into it with awareness of what can be done, and how, it'll work
better and you'll have more fun.
