Steam and Gas Turbines
Combining steam and gas turbines into one power generation system has been a tremendous boom for multiple industrial sectors. As Pirsh & Sage (n.d.). point out, "the major advantages advanced for such cycles were the improvement in overall cycle efficiency and the reduction in capital costs," (p. 39). A combined steam and gas turbine provides the best of both worlds by minimizing heat loss and maximizing energy output gains. Energy companies like GE have been actively promoting the use of combined steam and gas turbines; while others like ANSYS have been dedicated to the development of cutting-edge combined turbine systems for use in multiple sectors. In addition to their obvious applications in commercial and private power generation, combined steam and gas turbines also have rich potential for use in naval and maritime situations.
Gas and steam combined turbines are therefore available in a wide range of configuration for use in different scenarios. Nuclear power plants are gravitating toward the use of combined-cycle turbines in lieu of steam-only generators. Efficiency is the primary goal of both gas and steam turbines; and combined-cycle turbines provide the best possible solution. Combined steam and gas turbines "incorporate lower fuel usage and reduced carbon emissions," which characterizes efficient energy production (Gas and steam Turbines," n.d.). According to one source, "a combination of gas and steam turbine leads to efficiencies of over 50%," ("Start Your Engines: Gas Turbines," n.d.). When power stations can afford heat-force coupling systems, energy efficiency can be as high as 90% -- meaning nearly no energy loss ("Start Your Engines: Gas Turbines," n.d.). Boss (n.d.) points out that "the trend toward higher gas turbine firing and exhaust temperatures has made reheat combined-cycles common," (p. 1). Called Advanced-Combined Cycles, GE's STAG is a primary example. As with standard combined steam-gas cycle systems, the waste or run-off energy is harnessed and fed back...
Gas Turbine Systems A gas turbine, also known as a combustion generator, is a kind of inner combustion system. It consists of an upstream revolving compressor coupled to the downstream generator, as well as a combustion chamber amid the two. Power is included in the gas stream inside the combustor, where gas is combined with air as well as then ignited. Inside the high-pressure atmosphere of the combustor, burning of this
A large body of literature has treated many different aspects of these influences on Asia, Europe and the United States (Busser & Sadoi, 2003). The importance of the study relates to the current trends taking place in Libya where aggressive steps have been taken in recent years to normalize relations with the international community. For example, Libya opened up its programs to develop weapons of mass destruction to international
Business Nuclear power, under current conditions, is characterized by much lower regular emissions compared to energy from fossil fuel burning. But, it poses its own unique hazards, of which the most notable is risk of industrial accidents (e.g. Chernobyl) that have acute, long-term repercussions over huge areas. There are also security risks presented by vast inventories of materials that have the potential of being utilized as nuclear weapons; fossil fuels pose
alternatives to traditional fossil fuels, and evaluate them based on their relative availability, renewability, and known environmental impacts. We begin with a baseline characterization of fossil fuels, and outline some of the factors contributing to their current market and industry dominance. We then examine three of the current most prominent and viable renewable alternatives to fossil fuels, including the controversial nuclear energy technology and two emerging technology areas, wind
Different Fuel Cell Technologies U.S Department of Energy (2010) provides the description of different fuel cell technologies. The fuel cell technologies are differentiated according to their efficiency, operating temperatures, costs and application. The classifications are based on 6 major groups: Alkaline fuel cell (AFC), Phosphoric acid fuel cell (PAFC), Solid oxide fuel cell (SOFC), Molten carbonate fuel cell (MCFC), Proton exchange membrane fuel cell (PEMFC); Direct methanol fuel cell (DMFC). Alkaline fuel cell (AFC) The AFC generates electrical power
