want to, but I should mention another type of steam--and that is superheated steam. With a boiler (and we must now switch our thinking from a pressure cooker), we can pipe the steam from the boiler and pass the piping back through the firebox and add still more heat energy. This now converts the saturated steam to superheated steam.
