The corrosion damage and leakage of heat transfer tube steam generator were important factors nuclear power accident, which is closely related to the national production safety people's life property. influence size change cylindrical defect on burst pressure inconel690 alloy was studied by finite element simulation experimental measurement. According test data, relationship between parameter e...

In this paper, we survey some recent advances made in the field of bond graph modelling and show that bond graph modelling method is well suited to solve modelling, fault diagnosis and fault tolerant control problems in complex process engineering systems. We present a case study of development and implementation of fault tolerant control scheme for a steam generator process. Steam generator is...

An extension diagnosis method based on the matter-element model and extended correlation function is presented for vibration fault diagnosis of steam turbine generators. First, the matter-element models of the vibration fault are built according to diagnostics derived from practical experience and then, vibration faults in steam-turbine generators can be directly identified by relation indices....

Computational fluid dynamics (CFD) is adopted to calculate and analyze the performance separation mechanism of a steam-water equipment for pressurized water reactor (PWR) steam generator. The two-phase flow simulated by Euler two-fluid model, several representative droplet diameters are selected among 50 400 μm. influence diameter on investigated analyzing parameters such as phase volume fracti...

The sodium heated once-through steam generator (OTSG) is a vital barrier separating and the water loop in sodium-cooled fast reactor (SFR). In view of timeliness requirement OTSG operation performance evaluation, Fortran95 programming language used to optimize improve solution algorithm home-made transient analysis code, named TCOSS, for SFR OTSG, which modified into JFNK solving large sparse n...

Glycerol represents an emerging renewable bio-derived feedstock, which could be used as a source for producing hydrogen through steam reforming reaction. In this review, the state-of-the-art about glycerol production processes is reviewed, with particular focus on glycerol reforming reactions and on the main catalysts under development. Furthermore, the use of membrane catalytic reactors instea...
