Turbines, gas turbine

A more complex utility is combined heat and power (or cogeneration). Here, the heat rejected hy a heat engine such as a steam turbine, gas turbine, or diesel engine is used as the hot utility.

On-site combined heat and power (CHP) which has existed for years, includes turbines, reciprocating engines and steam turbines. Gas turbines in the 500-kW to 250-MW produce electricity and heat using a thermodynamic cycle known as the Brayton cycle. They produce about 40,000-MW of the total CHP in the United States. The electric efficiency for units of less... 

Even though most of the nitrous oxide formed is converted back to N2 through thermal dissociation or through reaction with H or O atoms, this source of NO is important, for instance, in gas turbines. Gas turbines are characterized by high pressure and moderate temperatures, and here reactions (R119) through (R121) compete favorably with thermal NO formation and become the major source of NO. 

The three main compressor types are rotary, reciprocating, and centrifugal. The compressor drives can be constant or variable speed, and can be driven by electric motors, steam turbines, gas turbines, gasoline, or diesel engine drives. For a particular application, the type of compressor is selected by considering the required capacity and discharge pressure. 

There are three main categories of turbines (i) gas turbines, (ii) steam turbines and (iii) water turbines. Gas turbines are mostly used in aircraft (Chapter 11), though aircraft-derived gas turbines are used for naval vessel propulsion, for stand-by generation of electricity and gas pipeline compression. Steam turbines have become increasingly compact in design and run under more vigorous conditions. 

In reference to die CHP mode, the industrial power plant with HTGR could be named CHHP , because it provides three energetical connection points high-temperature heat, low-temperature heat, and electricity. With respect to electricity production, the achievement of a 40 - 43 % efficiency is possible when using steam turbines. Gas turbines reach efficiencies up to 48 %. A combination of both could even reach the 50 % level. Cogeneration applications are estimated to allow efficiencies in the range of 80 - 90 % [24]. 

Relative to other advanced combustion conversion systems, such as magnetohydrodynamics (MHD), ceramic blade turbine gas turbine, and potassium Rankine cycle, thermionic development costs should be substantially lower. The cost effectiveness is a result of the modularity of thermionics, which makes it possible to perform mean-ingftil ejqreiiments with small equipment. Thus, large investments should not be required until there is a high prob-abihty of success.

Turbines are classified according to their principle of operation and the type of fluid that turns them. All turbines respond to impulse or reaction movement. The four main types of turbines are steam turbines, gas turbines, wind turbines, and water turbines. The primary function of a turbine is to convert steam, gas, wind, or water energy into mechanical energy that can be used to drive rotating equipment.

Power can be generated with several types of steam turbines, gas turbines (units 12, 27 and 30). Electrical generators can be driven by steam turbines or gas turbines. 

There are enormous number of utility units which can be employed in a utility system, namely boilers, back-pressure /condensing turbines, gas turbines, electric motors, steam headers at different pressure levels, condensers, auxiliary units, and all of their different combinations. If all of them are included in a superstructure, it will be too large to be... 

Another issue relating to the choice of pressure is that, as we have shown in Section 7.3, an improvement in the overall efhciency of fuel systems can be achieved by combining high-temperature fuel cells with gas turbines. Gas turbines require pressurised (typically 5 bar) hot exhaust gas. Solid oxide fuel cells are very suitable for this application, as they can run in a pressurised mode and have a high exhaust gas temperature. MCFCs could also be combined with GTs but the exhaust temperature is lower. In addition, for the reason described above, the molten carbonate system is not so amenable to pressurisation. Such systems are thus unlikely to be developed.
