GTE Gas Turbine Efficiency. Mar 17, 2015В В· Calculation Details Step 1: Determine Inlet Properties Using the Steam Property Calculator, properties are determined using Inlet Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality)., In the paper a calculation methodology of isentropic efficiency of a compressor and turbine in a gas turbine installation on the basis of polytropic efficiency characteristics is presented..

A steam turbine is driven with high pressure steam produced by . a boiler or heat recovery steam generator (HRSG). Unlike gas turbines or microturbines, steam turbines do not directly consume fuel. Rather, the fuel driving the process is the fired boiler or plant equipment that produces heat for the HRSG (e.g., a gas turbine). Table 1. The gas turbine efficiency, which is the function of turbine inlet temperature and the compression ratios, has increased significantly in the past decades, making it possible to reach 40–45% efficiency in simple cycle and beyond 60% efficiency (LHV) in natural gas fired combined cycles, a remarkable improvement over the E-class gas turbine

Gas Turbine Efficiency provides high-performing turbine management solutions, products and services from industry leading turbine specialists. Gas turbine manufacturers generally state the efficiency of their turbines using LHV. However, natural gas in the U.S. is bought and sold on an HHV basis, so be careful that you don't mix units.
