A monotube steam generator is a type of Steam generator (boiler), steam generator consisting of a single tube, usually in a multi-layer spiral, that forms a Heat recovery steam generator#Once-through steam generator, once-through steam generator (OTSG). The first of these was the Nathanael Greene Herreshoff, Herreshoff steam generator of 1873.

Principles
For the sake of efficiency, it is desirable to minimise the steam content of the generator. Heat can then be transferred efficiently into liquid water, rather than into low-density steam. Monotube steam generators may either boil gradually along their length, usually pumped circulation systems, but where this boiling does not disrupt the circulation. Otherwise they can use the Mark Benson (engineer), Benson Supercritical steam generator, supercritical system, where the pressure is sufficient to prevent boiling (within the heated volume) altogether.Examples
Examples of Monotube steam generators include: * Industrial steam generator (boiler), steam generators * The water-tube boilers of the monotube type used in steam cars, such as: ** AMC (1910 British automobile), AMC ** Steam generator (boiler)#Clayton, Clayton Steam Generator ** Doble steam car ** Gardner-Serpollet ** Locomobile Company of America ** White Motor Company, US patent 659,837 of 1900Flash boilers
A flash boiler is a particular type of low-water-content monotube boiler. Modern use is confined to model steam boats but, historically, flash boilers were used in Gardner-Serpollet steam cars.See also
