A MEMS Steam Generator
Previous work [1] has shown that MEMS technology has significant potential to create more compact, higherperforming hardware for chemical oxygen iodine lasers (COIL). In COILs, the laser medium is a flowing gas that must be pumped through the system at high mass flow rates to ensure proper system operation. As a result, compact pumps with high pumping rates are a key element of the COIL system....
متن کاملVibration analysis of a steam turbine blade
ABSTRACT Blade failure is a common problem of a steam turbine and it’s failure in-service results in safety risks, repair cost and non operational revenue losses. Thus, the reliability of these blades is very important for the successful operation of a steam turbine. Dynamic analysis of a steam turbine blade in computational environment is carried out in the present work. In order to gain physi...
متن کاملExergy Analysis of a Molten Carbonate Fuel Cell-Turbo Expander-Steam Turbine Hybrid Cycle
Exergy analysis of an integrated molten carbonate fuel cell-turbo expander-steam turbine hybrid cycle has been presented in this study. The proposed cycle has been used as a sustainable energy approach to provide a micro hybrid power plant with high exergy efficiency. To generate electricity by the mentioned system, an externally reformed molten carbonate fuel cell located upstream of the combi...
متن کاملTurbo-Generator Vibration Fault Diagnosis Based on PSO-BP Neural Networks
To overcome the flaws of traditional BP learning algorithm of its low convergence speed and easy falling into local extremum during turbo-generator vibration faults diagnosis, a novel algorithm called PSO-BP is proposed for artificial neural network (ANN) learning based on particle swarm optimization (PSO) in this paper. The algorithm covers the two phases. Firstly, PSO algorithm is applied to ...
متن کاملOverview of Steam Generator Tube-Inspection Technology
Degradation of steam generator (SG) tubing due to both mechanical and corrosion modes has resulted in extensive repairs and replacement of SGs around the world. The variety of degradation modes challenges the integrity of SG tubing and, therefore, the stations’ reliability. Inspection and monitoring aimed at timely detection and characterization of the degradation is a key element for ensuring ...
