Finned tube banks configuration for the utilization of waste heat from a gas turbine station

In this work, a computational model was developed to predict and analyze static behavior in two different systems of dual-pressure finned tube banks to be used behind a gas turbine station without a pre-existing heat recovery system. The relevant physical phenomena were accounted for by means of a non-linear approach and the difference between water and steam velocities in finned tubes. Simulations were also done considering the effects of exhaust gas parameters and tube length on the flow-fields of the working fluid. The results revealed the different static performance of these models on the sides of the working fluid and exhaust gas.
