Conventional OTSG Development for Heavy Liquid Fuel Firing in Thermal Applications

International Thermal Operations and Heavy Oil Symposium, 2008
Abstract The large expansion in future Canadian extra heavy oil in situ thermal production (e.g. SAGD) projects will dramatically increase the demand for natural gas, the current predominant fuel used for the associated steam generation. For thermal (SAGD) applications, depending on the Steam Oil Ratio (SOR), approximately

OTSG Transient Modeling with ALMOD/GDE: Overview and Case Study

1984
In spite of their relatively simple design, once-though-steam generators (OTSG) with integral economizer (IE) continue to present a challenge to the analyst wanting to make best estimate predictions of their behavior under a variety of actual and postulated conditions.

Domain-Adaptive Physics-Informed Transformer for SMR OTSG

The operational optimization of Small Modular Reactors critically depends on accurate real-time monitoring of Once-Through Steam Generators. Complex thermo-fluid phenomena within OTSGs present significant modeling challenges, making high-fidelity simulations computationally prohibitive; meanwhile, conventional data-driven models suffer from out-of ...

Evaluation of RELAP5/MOD1 for Analysis of Steam Generator Tube Rupture Transients in OTSG Plants

1984
The RELAP5/MOD1, Cycle 18 code (1) was used to evaluate the system response of a Babcock and Wilcox plant having 177 fuel assemblies and a lowered loop configuration to the rupture of single tube or multiple tubes in one or both once-through steam generators (OTSGs).
