Once through steam generators adopt water tube design. There is no drum in the boiler proper. Once through steam generator is composed by many water pipe, the water is fluid in the pipe and heated by fire. This design makes the boiler just need 7 minutes to produce steam from start. Once through steam generators are widely used in Laundry, Hospital, School, Textile Industry.
