OVERVIEW: Growing concern about environmental problems caused by thermal power plants is making the reduction of CO2 through more efficient power generation and the reduction of NOx and other emissions a top priority. The deregulation of the electric power industry, meanwhile, is helping to expand the demand for medium-capacity, high-efficiency thermal power plants geared toward IPP (independen...

Simulators play a very important role in the operation of thermal power plants and also in the design of control systems for these plants. To cater to this requirement elaborate methodologies have been developed to simulate thermal power plant processes in an interactive way. Due to the intensive computations involved, such simulators use one or more high through-put computers known as the simu...

The studies of the behavior of fluid on the nano-level has shown to be an important means of influencing the characteristic of fluid must especially in the area of thermal conductivity. Giving relevance in numerous fields such as biomedicine, manufacturing, fuel cells and soon on. This article considers flow and heat transfer of viscous fluid conveying Gold nanoparticles through expanding or co...

The paper describes the development and testing of a neural network based drum level controller for sub-critical thermal power plant boilers. Experimental data obtained from an operational coal fired power plant (500MW Thermal Power Station, Korba, India) is used to train the neural network. This model proposes a simple training algorithm for a class of nonlinear systems, which enables the neur...

This paper presents a modeling and control method for thermal power plants having nonlinear dynamics varying with load. First a load-dependent exponential ARX (Exp-ARX) model that can effectively describe the plant nonlinear properties and requires only off-line identification is presented. The model is then used to establish a constrained multivariate multi-step predictive control (ExpMPC) str...

The selection and design of materials that will withstand the extreme conditions of a fusion power plant has been described as one of the greatest materials science challenges in history. The high particle flux, high thermal load, thermal mechanical stress and the production of transmutation elements combine to produce a uniquely hostile environment. In this paper, the materials favoured for th...

Solar parabolic concentrating collectors are widely and efficiently used in electrical generation. They were experimentally validated in worldwide pioneer plants. SEGS-VI 30 MW solar power plant built in southern California is one of these plants that was commissioned many years ago. In this work a possibility of installing such plant in Makkah, 21.4 °N located in moderate latitudes is studied....
