In the final retail version, only 2 do this.
They're both located in Liberty Campus:

http://i42.tinypic.com/sl061i.jpgThis one, however, is on the sidewalk.(look to the right in the BG, if you can't see it.) No steam in retail.
Now, what i'm wondering...would it be possible to make steam come out of them again? Is this controlled by particle.cfg or timecyc? Or is it controlled by the .exe?
EDIT:Here's where I think the steam is coming from on the last one:
