Parametric Analysis of Cooled Gas Turbine Cycle with Evaporative Inlet Air Cooling
The article investigates the effect of compressor pressure ratio, turbine inlet temperature and ambient temperature on the performance parameters of an air-cooled gas turbine cycle with evaporative cooling of inlet air. Air f ilm cooling has been adopted as the cooling technique for gas turbine blades. The mass of coolant required for turbine blade cooling is calculated f or a selected range of...
متن کاملPerformance Improvement of a Regenerative Gas Turbine Cycle Through Integrated Inlet Air Evaporative Cooling and Steam Injection
Like many developed countries, energy efficiency and environment impact are the most important process in the development of power generation policy in India. A high ambient temperature reduces the air density and makes inlet air cooling (IAC) and steam injection gas turbine (STIG) attractive power augmentation method for existing regenerative gas turbine. With a high back work ratio and a high...
متن کاملIntegration of steam injection and inlet air cooling for a gas turbine generation system
The temperature of exhaust gases from simple cycle gas turbine generation sets (GENSETs) is usually very high (around 500 C), and a heat recovery steam generator (HRSG) is often used to recover the energy from the exhaust gases and generate steam. The generated steams can be either used for many useful processes (heating, drying, separation etc.) or used back in the power generation system for ...
متن کاملExergy, Economic and Environmental Analyses of Gas Turbine Inlet Air Cooling with a Heat Pump Using a Novel System Configuration
Gas turbines incur a loss of output power during hot seasons due to high ambient air temperatures, and input air cooling systems are often used to partly offset this problem. Here, results are reported for an investigation of the utilization of a heat pump to cool the inlet air of a gas turbine compressor. The analyses are carried out for two climates: the city of Yazd, Iran, which has a hot, a...
متن کاملOptimization and increase production and efficiency of gas turbines GE-F9 using Media evaporative cooler in Fars combined cycle power plant
Gas turbines play an important role in supplying power for the country especially in peak electricity load. The main disadvantages are the turbines, they produce large changes are a result of climate change. However, in times of peak electricity grid and at the same time warm months, can produce gas turbines under the effect of ambient temperature, the amount of reduced considerably. The method...
