Note:
This paper mainly aims at demonstrating that an appropriate thermo-fluid-dynamic design optimization of duct-burners for combined-cycle and cogenerative plants allows to satisfy the restrictive emission limits, while significantly reducing the thermal stresses and the undesired pressure drop. In particular, a detailed discussion on the influence of the TEG composition and of thermal load, measured for a standard duct-burner, is proposed to justify component failure registered in plant applications.
On this basis, the paper also addresses an important design criterion, usually neglected, which allows to realize long-life and maintenance-free duct-burners, while retaining the fundamental requirement of limiting emissions. Finally, the influence of the thermal load onto the emissions produced by the modified duct-burner has been experimentally measured, and analyzed also with the aid of some numerical computations.
