Book Description
The ideal power cycle components/processes (compression, combustion and expansion) are presented in this technical background technical material. When dealing with power cycle components/processes (compression and expansion), air, argon, helium and nitrogen are used as the working fluid. When dealing with combustion, six different fuels (carbon, hydrogen, sulfur, coal, oil and gas) react with air and oxygen enriched air as the oxidant at different stoichiometry values (stoichiometry => 1) and oxidant inlet temperature values. For compression and expansion, the technical performance of mentioned power cycle components/processes is presented with a given relationship between pressure and temperature. While for combustion, the technical performance at stoichiometry => 1 conditions and is presented knowing the enthalpy values for combustion reactants and products, given as a function of temperature. This course provides the compression and expansion T - s diagrams and their major performance trends plotted in a few figures as a function of compression and expansion ratio values and working fluid mass flow rate. For each combustion case considered, combustion products composition on both weight and mole basis is given in tabular form and plotted in a few figures. Also, flame temperature, stoichiometric oxidant to fuel ratio and fuel higher heating value (HHV) are presented in tabular form and plotted in a few figures. The provided output data and plots allow one to determine the major combustion performance laws and trends. In this technical background material, one gets familiar with the ideal power cycle components/processes and their T - s and h - T diagrams, operation and major performance trends.

Book Description
The ideal, simple and basic power cycles (Carnot Cycle, Brayton Cycle, Otto Cycle and Diesel Cycle), ideal power cycle components/processes (compression, combustion and expansion) and ideal compressible flow components (subsonic nozzle, diffuser and thrust) are presented in this technical background material. When dealing with power cycles two different approaches are taken with respect to the working fluid. For Carnot Cycle and Brayton Cycle, air, argon, helium and nitrogen are considered as the working fluid. For Otto Cycle and Diesel Cycle, only air is used as the working fluid. When dealing with power cycle components/processes (compression and expansion) and compressible flow (nozzle, diffuser and thrust), air, argon, helium and nitrogen are used as the working fluid. When dealing with combustion, six different fuels (carbon, hydrogen, sulfur, coal, oil and gas) react with air and oxygen enriched air as the oxidant at different stoichiometry values (stoichiometry => 1) and oxidant inlet temperature values. For each power cycle thermal efficiency derivation is presented with a simple mathematical approach. Also, for each power cycle, a T - s diagram and power cycle major performance trends (thermal efficiency, specific power output, power output, combustion products composition on weight and mole basis, specific fuel consumption and stoichiometry) are plotted in a few figures as a function of compression ratio, turbine inlet temperature and/or final combustion temperature and working fluid mass flow rate. It should be noted that this technical background material does not deal with costs (capital, operational or maintenance). For compression and expansion, the technical performance of mentioned power cycle components/processes is presented with a given relationship between pressure and temperature. While for combustion, the technical performance at stoichiometry => 1 conditions is presented knowing the enthalpy values for combustion reactants and products, given as a function of temperature. This course provides the compression and expansion T - s diagrams and their major performance trends plotted in a few figures as a function of compression and expansion ratio values and working fluid mass flow rate. For each combustion case considered, combustion products composition on both weight and mole basis is given in tabular form and plotted in a few figures. Also, flame temperature, stoichiometric oxidant to fuel ratio and fuel higher heating value (HHV) are presented in tabular form and plotted in a few figures. The provided output data and plots allow one to determine the major combustion performance laws and trends. For subsonic nozzle, diffuser and thrust, the technical performance of mentioned compressible flow components is presented with a given relationship between temperature and pressure as a function of the Mach Number. This technical background material provides the compressible flow components T - s diagrams and their major performance trends (stagnation over static temperature and pressure ratio values) are plotted in a few figures as a function of the Mach Number. In this technical background material, one gets familiar with the ideal simple and basic power cycles, power cycle components/processes and compressible flow components and their T - s and h - T diagrams, operation and major performance trends.

Book Description
Faced with the climate change phenomena, humanity has had to now contend with numerous changes, including our attitude environment protection, and also with depletion of classical energy resources. These have had consequences in the power production sector, which was already struggling with negative public opinion on nuclear energy, but a favorable perception of renewable energy resources. The objective of this edited volume is to review all these changes and to present solutions for future power generation.

Book Description
Fossil-fuel power plants account for the majority of worldwide power generation. Increasing global energy demands, coupled with issues of ageing and inefficient power plants, have led to new power plant construction programmes. As cheaper fossil fuel resources are exhausted and emissions criteria are tightened, utilities are turning to power plants designed with performance in mind to satisfy requirements for improved capacity, efficiency, and environmental characteristics.Advanced power plant materials, design and technology provides a comprehensive reference on the state of the art of gas-fired and coal-fired power plants, their major components and performance improvement options. Part one critically reviews advanced power plant designs which target both higher efficiency and flexible operation, including reviews of combined cycle technology and materials performance issues.Part two reviews major plant components for improved operation, including advanced membrane technology for both hydrogen (H2) and carbon dioxide (CO2) separation, as well as flue gas handling technologies for improved emissions control of sulphur oxides (SOx), nitrogen oxides (NOx), mercury, ash and particulates. The section concludes with coverage of high-temperature sensors, and monitoring and control technology that are essential to power plant operation and performance optimisation.Part three begins with coverage of low-rank coal upgrading and biomass resource utilisation for improved power plant fuel flexibility. Routes to improve the environmental impact are also reviewed, with chapters detailing the integration of underground coal gasification and the application of carbon dioxide (CO2) capture and storage. Finally, improved generation performance is reviewed with coverage of syngas and hydrogen (H2) production from fossil-fuel feedstocks.With its distinguished international team of contributors, Advanced power plant materials, design and technology is a standard reference for all power plant engineers and operators, as well as to academics and researchers in this field. - Provides a comprehensive reference on the state-of-the-art gas-fired and coal-fired power plants, their major components and performance improvement options - Examines major plant components for improved operation as well as flue gas handling technologies for improved emissions control - Routes to improve environmental impact are discussed with chapters detailing the integration of underground coal gasification
