EFFECT OF DUAL-PRESSURE TUBE BANKS SYSTEMS IN PARALLEL CONFIGURATION ON THE WASTE HEAT UTILIZATION FROM A GAS TURBINE POWER PLANT

摘要

In the present paper, two models of dual-pressure tube systems in parallel configuration are developed and analyzed in order to predict the system performances by optimizing the exhaust gas utilization from a gas turbine without heat recovery systems. Finned tube banks arranged behind a gas turbine are used to improve the heat transfer efficiencies. Simulations are accomplished to prove the effectiveness of the present work in performance prediction of the dual-pressure tube systems. The obtained results demonstrate the different operating behavior of the developed models considering combined effects of the exhaust gas parameters and the tube geometries.
