Background and objectives: Bakhtiari savory belonging to the Lamiaceae family is an endemic species, which is rich in carvacrol, thymol and other aromatic compounds. The essential oil of the plant could be added in fatty food against radicals similar to synthetic antioxidant BHT. Methods: To determine the best extraction methods on qualitative and antioxidant c...

A thermodynamic analysis of an operational 315 MW supercritical steam power plant (SPP) using the actual data is performed to assess the plant performance and identify the sites of energy losses and exergy destructions in each component of the plant. Various performance parameters such as component energy and exergy efficiencies, energy loss rate, exergy destruction rate, improvement potential ...

A steam generator is the major component of a nuclear power plant and its integrity is crucial for the nuclear safety. Steam generator tube eddy current bobbin inspections are periodically performed for utility to detect tube degradation. Scaled deposits on the steam generator tubes cause the performance degradation problem and the thickness of the outer diameter tube surface can be measured us...

Concentrated Solar Power plants are complex systems subjected to quite sensitive variations of the steam production profile and external disturbances, thus advanced control techniques that ensure system stability and suitable performance criteria are required. In this work, a multi-objective H∞ robust controller is designed and applied to the power control of a Concentered Solar Power plant com...

Nuclear power plant safety performance indicators are developed "by nuclear operating organisations to monitor their own performance and progress, to set their own challenging goals for improvement, and to gain additional perspective on performance relative to that of other plants". In addition, performance indicators are widely used by regulatory authorities although the use is not harmonised....

biomass co-firing with lignite represents an attractive solution for operating lignite-fired thermalpower plants (tpp) with the dual advantage of using local renewable resources and simultaneously reducingemissions. the subject of this study is technical and environmental investigation of the feasibility of the cofiring of soma lignite with some dried agricultural residues in the soma thermal p...

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...
