      The steam distribution system transports the steam to the consumers. The pressure in the steam distribution system is usually between 2 and 12 bar, where steam with a pressure of between 2 and 5 bar is called low-pressure steam, and medium-pressure steam has a pressure of between 9 and 12 bar (SFI, 1990). In the steam distribution system condensate is formed, due to cooling of the steam.

      Superheated Steam Water Tube Marine Boilers - Bright Hub

      Marine boilers produce high pressure superheated steam to drive the turbines. The steam is generated by the water tubes which connect the water drum to the steam drum. Water and steam circulate through the vertical banks of tubes; the inner ones supplying the top drum and the outer ones dropping steam and water back to the water drum. The water tubes are heated by heavy fuel oil, which is
