    Pdf 32 Methods of improving performance of the gas turbine seminar reports/pdf/ppt download

    Introduction: Gas turbines are used in various applications in different regions of the world. Therefore always tend to find ways to improve the overall cycle of the plant.

    Cooling of air at the intake helps increasing the density of air flowing into the plant and increases the power output.

    Several attempts have been made by the researches in new cooling techniques mostly concerned with evaporative coolers, chillers etc.

    There are many types of air cooling techniques like evaporative inlet air cooling, absorption cooling and mechanical compression.

    An absorptive cooler is the one in which a low grade energy is used to drive the system and generate the cooling effect.

    Evaporative cooling is considered to be the cheaper and the simplest one. But it is highly efficient in dry and hot ambient conditions only.

    Reports have suggested a 10% to 20% rise in power output by direct controlled spray of water.

    Researchers have also reported that for every 1% rise in power output there must be a fall of 0.6oC in the temperature of the working fluid.



    In absorption cooling refrigerants such as the ammonia or lithium bromide is used. The rise in thermal efficiency of the cycle is 4% when compared to that of the evaporative cooling which is around 2.2%.


    But care should be taken that the cooling effect never takes the working fluid temperature below 280 K which may lead to formation of ice crystals in the compressor blades and decreases the performance of it since the air temperature drops by 6K as it enters the compressor.
