Indeed in a railway engine. But in ships' steam engines the used steam is f=
ed into a condenser to recover the water, as seawater is not good in a boil=
er, and the coal furnace has to get its draught some other way, and that is=
why in my experience big steam ships make coal smoke but do not go "ch ch =
ch ch" like a railway engine.

In my understanding of typical steam engine designs, the used steam is usua=
lly vented upward in a jet concentric with the boiler=E2=80=99s chimney in =
order to amplify the draft, making the coal burn hotter and generate more s=
team. So, the only place the =E2=80=9Cused steam=E2=80=9D is vented is in t=
he same gas stream as the gases from its coal burning. I would expect the t=
erm =E2=80=9Cexhaust=E2=80=9D for a steam engine to imply both used steam A=
ND gases from the coal flame.
This is why a steam engine=E2=80=99s chimney goes =E2=80=9Cchug, chug, chug=
=E2=80=9D and comes out in percussive billows and doesn=E2=80=99t just look=
like the chimney for a normal fireplace in a home.
