2019-5-13 · Once-through steam generator (OTSG) A specialized type of HRSG without boiler drums is the once-through steam generator. In this design, the inlet feedwater follows a continuous path without segmented sections for economizers, evaporators, and superheaters.
2019-5-16 · Once Through Steam Generators (OTSGs) are very similar to Heat Recovery Steam Generators (HRSGs) except for the actual process of steam generation in their evaporator section(s). N/E under a license from Siemens AG utilizes two single pass evaporator stages to evaporate and partially superheat the steam flow in the once through evaporator section.
BWX Technologies, Inc. has the experience, expertise and flexibility to design and build steam generators to the demanding specifications of each individual customer.. The OTSG is a vertical shell counterflow straight-tube heat exchanger design which directly generates superheated steam as the feedwater flows through the steam generator in a single pass.

The five sections of the once-through steam generator are evident in this photo at the SynCrude Canada oil sand production facility: inlet duct, plenum, boiler section, hood and stack.
2014-4-19 · 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.

2019-5-1 · A Monotube steam generator is a type of steam generator consisting of a single tube, usually in a multi-layer spiral, that forms a Once Through Steam Generator (OTSG).The first of these was the Herreshoff steam generator of 1873.
Review of Once-Through Steam Generators - OnePetro
The once-through generator was specifically developed for thermal flooding applications and provides features not available in conventional steam boilers. Among the important advantages are the following: 1. It will handle feedwater with a relatively high percentage of solids, provided the solids have been converted to soluble form. 2.
Once Through Heat Recovery Steam Generators (OTSGs) are the most significant advancement in steam generation in over a century. Until the 1980s, conventional drum boilers were used to produce steam. At about this time, the US Navy investigated the use of combined gas turbine and steam turbine plants for additional ship propulsion power.
2012-12-5 · The steam generators are designed to remove the heat generated in the reactor vessel, and utilize the once-through concept to produce dry, superheated steam at the outlets of the steam generator. Each once-through steam generator (OTSG) is a vertical, straight, tube-and-shell heat exchanger which produces superheated steam at
