Investigation of the Combined Effect of Variable Inlet Guide Vane Drift, Fouling, and Inlet Air Cooling on Gas Turbine Performance
entropy Article Investigation of the Combined Effect of Variable Inlet Guide Vane Drift, Fouling, and Inlet Air Cooling on Gas Turbine Performance Muhammad Baqir Hashmi , Tamiru Alemu Lemma * and Zainal Ambri Abdul Karim Department of Mechanical Engineering, Universiti Teknologi PETRONAS, Bander Seri Iskandar, 31750 Tronoh, Perak Darul Ridzuan, Malaysia; [email protected] (M.B.H.); [email protected] (Z.A.A.K.) * Correspondence: [email protected]; Tel.: +605-368-7018 Received: 18 October 2019; Accepted: 28 November 2019; Published: 1 December 2019 Abstract: Variable geometry gas turbines are susceptible to various malfunctions and performance deterioration phenomena, such as variable inlet guide vane (VIGV) drift, compressor fouling, and high inlet air temperatures. The present study investigates the combined effect of these performance deterioration phenomena on the health and overall performance of a three-shaft gas turbine engine (GE LM1600). For this purpose, a steady-state simulation model of the turbine was developed using a commercial software named GasTurb 12. In addition, the effect of an inlet air cooling (IAC) technique on the gas turbine performance was examined. The design point results were validated using literature results and data from the manufacturer’s catalog. The gas turbine exhibited significant deterioration in power output and thermal efficiency by 21.09% and 7.92%, respectively, due to the augmented high inlet air temperature and fouling. However, the integration of the inlet air cooling technique helped in improving the power output, thermal efficiency, and surge margin by 29.67%, 7.38%, 32.84%, respectively. Additionally, the specific fuel consumption (SFC) was reduced by 6.88%. -

Appendix B Supporting Material for BACT Review for Electrical Generation Technologies
Appendix B Supporting Material for BACT Review For Electrical Generation Technologies I. INTRODUCTION Discussed in detail below are recommended emission levels for electrical generation sources using small gas turbines (rated at less than 50 MW in size), reciprocating engines using fossil fuel, and gas turbines / reciprocating engines using waste gas. The discussion below is based upon the requirements for determining Best Available Control Technology (BACT) in California and that BACT in California is equivalent to federal requirements for lowest achievable emission rate (LAER). BACT is generally specified as the most stringent emission level of these three alternative minimum requirements: 1) the most stringent emission control contained in any approved State Implementation Plan (SIP); 2) the most effective control achieved in practice; and 3) the most efficient emission control technique found by the district to be both technologically feasible and cost effective. This appendix provides the basis for the information presented in Chapter V (BACT for Electrical Generation Technologies). This appendix addresses BACT determinations for oxides of nitrogen (NOx), volatile organic compounds (VOC), carbon monoxide (CO), and particulate matter (PM). For the most effective control achieved in practice, examples were provided of emission levels specified in preconstruction permits issued by California districts and other states, and the most stringent emission levels achieved in practice. For each example cited, the following information is included: the name of the facility the equipment is located at, the applicable California district or State making the determination, a description of the basic equipment, and the method of control used to reduce emissions. In addition, for the control techniques required, the status of the permit (authority to construct/permit to construct or permit to operate) and the emission levels established by the permitting agency are provided. -
Gas Turbine Engines.Pdf
GAS TURBINE ENGINES The simplified operation of the gas turbine engine is as follows: 1. Air is taken in, and compressed to a high pressure. 2. The compressed air is then mixed with a fuel and ignited, producing high-velocity, high- pressure gas. 3. This gas is then used to turn a turbine, providing useful work, and the exhaust gases emitted, sometimes through a nozzle. The turbine itself is used to power the compressor, through the use of a coupling shaft between turbine and compressor. For this reason a starter motor must be employed in order to bring the engine up to speed when starting. Below is a diagrammatic representation of a gas turbine engine showing the fundamental processes: A useful way of looking at the workings of the gas turbine engine is to view it as following the same process as a reciprocating IC engine. Air is drawn in, compressed, ignited, expanded and exhausted in the both the reciprocating IC and gas turbine engines. The difference is that in a gas turbine engine these processes are not carried out in one cylinder, but rather are spread over different components of the engine. The three main stages of the engine are now examined in further detail. Compression In this stage either centrifugal or axial compressors are employed to compress the ambient air to a high pressure. Some of this air will then be fed into the combustion chamber, whilst some will be used to cool the turbine. The ratio of final pressure to ambient pressure is called the pressure ratio and for a modern engine may be as high as 40:1.Centrifugal compressors, although cheaper to manufacture, are less widely used because they are unable to achieve such high pressure ratios. -
Our New Edition of Our Annual Newsletter, Your Information Source to the Canadian Gas Turbine Industry. the IAGT
Welcome to our new edition of our annual newsletter, your information source to the Canadian gas turbine industry. The IAGT Gas Turbine Newsletter summarizes some previous Committee activities, and addresses today’s developments to inform you about upcoming events and new developments of interest to all of us connected to the industry. The newsletter is available on the IAGT website at iagtcommittee.com. Contributions, feedback and suggestions to the Symposium and to the Newsletter are welcome and can be sent via e-mail to the addresses on the back page. The Industrial Application of Gas Turbines (IAGT) Committee, formed in 1973 under the sponsorship of the National Research Council of Canada, is a Technical Advisory Group to Canadian industry and government. The group provides a forum for the exchange and dissemination of ideas and the communication of new developments related to the industrial application of gas turbines in Canada. Presently under the sponsorship of the Canadian Gas Association and the National Research Council, the IAGT Committee's specific functions relate to the organization of a biennial technical symposium and a fall Forum held on alternate years from the Symposium. The Symposium provides the venue for the presentation of technical papers and discussion panels covering all aspects of industrial gas turbine operation as well as providing a forum for reviewing directives, guidelines, codes and practices, as issued by Regulatory Agencies, which impact directly on the application of gas turbines. The IAGT Committee members are listed on the website and we thank those members who volunteer their time and effort to the Canadian Gas Turbine Industry. -
