Abstract

This study investigates the performance and economic benefits of applying inlet fogging in a heavy duty industrial gas turbine. To achieve the aim of the study, a heavy duty industrial gas turbine engine was modelled using a gas turbine performance software, GasTurb. The modelled engine was derived from the Frame 9E class of gas turbines. Consequent upon completing the engine modelling, ambient temperature profile data obtained from a location in Niger Delta region of Nigeria were used as input into the engine model to simulate its effect on the engine performance. Inlet fogging was simulated on the industrial gas turbine by inputting a water-to-air ratio of 0.4%, to cool and reduce the air inlet temperature by 10 degree Celsius. The simulation plots show that the gas turbine performance which dropped as a result of increased ambient temperature was enhanced by the application of inlet fogging. Economic analysis shows that approximately $2.4 million profit was recorded in one year when inlet fogging system was employed.

重型工业燃气轮机进气雾化系统的性能及技术经济分析

研究了重型工业燃气轮机进口雾化的性能和经济效益。为了达到研究的目的，使用燃气轮机性能软件GasTurb对重型工业燃气涡轮发动机进行了建模。模型发动机源自Frame 9E级燃气轮机。在完成发动机建模之后，从尼日利亚尼日尔三角洲地区某地获得的环境温度剖面数据被用作发动机模型的输入，以模拟其对发动机性能的影响。在工业燃气轮机上，通过输入0.4%的水气比来模拟进气起雾，使进气温度降低10摄氏度。仿真结果表明，进气雾化改善了由于环境温度升高而导致的燃气轮机性能下降的问题。经济分析显示，采用进口雾化系统后，一年的利润约为240万美元。

期刊介绍： The purpose and scope of the International Journal of Thermodynamics is · to provide a forum for the publication of original theoretical and applied work in the field of thermodynamics as it relates to systems, states, processes, and both non-equilibrium and equilibrium phenomena at all temporal and spatial scales. · to provide a multidisciplinary and international platform for the dissemination to academia and industry of both scientific and engineering contributions, which touch upon a broad class of disciplines that are foundationally linked to thermodynamics and the methods and analyses derived there from. · to assess how both the first and particularly the second laws of thermodynamics touch upon these disciplines. · to highlight innovative & pioneer research in the field of thermodynamics in the following subjects (but not limited to the following, novel research in new areas are strongly suggested): o Entropy in thermodynamics and information theory. o Thermodynamics in process intensification. o Biothermodynamics (topics such as self-organization far from equilibrium etc.) o Thermodynamics of nonadditive systems. o Nonequilibrium thermal complex systems. o Sustainable design and thermodynamics. o Engineering thermodynamics. o Energy.
