proportional to the absolute temperature of the gas passing through the device. Consequently, it is advantageous to operate the expansion turbine at the highest practical temperature consistent with economic materials and internal blade cooling technology and to operate the compressor with inlet air flow at as low a temperature as possible. As technology advances permit higher turbine inlet temperature, the optimum pressure ratio also increases. There are several variations of the Brayton cycle in use today. Fuel consumption may be decreased by preheating the compressed air with heat from the turbine exhaust using a recuperator or regenerator. The compressor work may also be reduced and net power increased by using intercooling or precooling techniques. In a combined cycle, the exhaust may be used to raise steam in a boiler and to generate additional power. Figure 3-1 shows the configuration for an unrecuperated industrial gas turbine with shaft power, driving an electric generator and the exhaust heat powering a heat recovery steam generator (HRSG) with supplementary firing capability. Figure 3-1. Gas Turbine Configuration with Heat Recovery Source: University of Calgary Gas turbine exhaust is quite hot, up to 800 to 900°F for smaller industrial turbines, and up to 1,100°F for some new, large central station utility machines and aeroderivative turbines. Such high exhaust temperatures permit direct use of the exhaust for applications such as combustion air preheating, drying, or other applications requiring hot air stream. Such direct use of the exhaust is also called closely coupled CHP. More commonly, the exhaust heat is recovered with the addition of a heat recovery steam generator, which produces steam or hot water. A portion or all of the steam generated by the HRSG may be used to generate additional electricity through a steam turbine in a combined cycle configuration. A gas turbine system is considered to be a combined heat and power (CHP) configuration if the waste heat (i.e., thermal energy) generated by the turbine is applied in an end-use. For example, a simple-cycle gas turbine using the exhaust in a direct heating process is a CHP system. A gas turbine system that uses the turbine exhaust in a HRSG, and then uses the steam from the HRSG to produce electricity in a steam turbine is a combined cycle unit, and is not considered to be CHP (no end-use thermal need). This latter configuration is a waste heat-to-power (WHP) system. Catalog of CHP Technologies 3–3 Combustion TubinesPDF Image | EPA CHP Technologies Combustion Turbines
