Gas Turbine Optimum Arrangement for Process Plants

The gas turbine is a power plant, which produces a great amount of energy for its size and weight. Its compactness, low weigh, and multiple fuels make it a natural power plant for various industries such as power generation or oil and gas process plants. In any of these applications, the performance and stability of the gas turbines are the end products that strongly influence the profitability of the business that employs them. Control and analyses of gas turbines for achieving stability and good performance are important so that they have to operate for prolong period. Effective control system design usually benefits from an accurate dynamic model of the plant. Characteristic component parts of the system are considered in this model. Gas turbine system is described by specified thermodynamic equations that can be used for defining its model. This paper introduces an optimal LQG/LTR control method for a gas turbine. Analysing the gas turbine dynamic in time and frequency domain by using proposed control compared to PID controller is followed. Applying this optimal control method can provide good performance and stability for the component parts of system.

Gas Turbine Compressor

Pneumatic starting systems for gas turbine engines are discussed. A general description of various energy sources, system components and arrangements is included. Systems are reviewed from the standpoint of energy utilization, versatility and reliability. It is concluded that the auxiliary gas turbine compressor/air turbine starter combination is the optimum arrangement, and, without a doubt, it will continue to be the primary starting means in gas turbine engine applications.

Turbine Exhaust

Energy costs can be reduced in most large process plants by the use of turbines to supply power and heat. Performance characteristics of gas turbines, gas turbine exhaust heat boilers and combined gas-steam turbine cycles, plus the typical heat balance diagrams included in this paper will help the reader visualize economic applications for turbines in different industrial plants. The effect different fuels have on gas turbine maintenance (costs and downtime) and other application parameters are included. The information provided will permit the user to assess his own situation and then select the most economic fuel for a specific gas turbine application.
