A model-based controller (Dynamic Matrix Control) and an intelligent controller (Fuzzy Logic Control) have been designed and implemented for steam temperature regulation of a 300 MW thermal power plant. The temperature regulation is considered the most demanded control loop in the steam generation process. Both proposed controllers Dynamic Matrix Controller (DMC) and Fuzzy Logic Controller (FLC...

To accurately detect deformation and extend the component life beyond the original design limits, structural safety monitoring techniques have attracted considerable attention in the power and process industries for decades. In this paper an on-line monitoring system for high temperature pipes in a power plant is developed. The extension-based sensing devices are amounted on straight pipes, T-J...

High-temperature steam/CO 2 electrolysis process has been the scope of study for last decades. This confers a feasible and environmental approach to convert low-carbon electrical energy into chemical energy, stored in form synthetic gas (H CO) be further processed line with final use target. It focuses on Power-to-Methane technology using high-temperature molten carbonates electrolyzer (MCEC). ...

The energy system analysis of an integrated process producing synthetic natural gas (SNG) from woody biomass has been carried out. Two different configurations have proposed and modeled, considering the integration between gasification, solid oxide electrolysis (SOEC) catalytic reactors for methane synthesis. two investigated differ in size SOEC unit. In first configuration, unit is sized to in...

Tap water is one of the causative factors of hospital infections. We examined the disinfective potential of electrolysis and mechanism of disinfection, and clarified the disinfective effect of electrolysis on tap water contaminated with bacteria, and discussed its clinical applications. Tap waters artificially contaminated with Pseudomonas aeruginosa, Escherichia coli, Legionella pneumophila, a...

Presented here are results of research performed at Portland State University during the period 1994 to 1996. Excess heat was produced at the rate of about 1.2 watts during electrolysis of heavy water with a titanium cathode weighing 0.0625g. Analysis of the electrodes before and after electrolysis with a scanning electron microscopy (SEM) and an energy dispersive spectrometer (EDS) revealed th...
