Superheater Design Assessment for Flexible Solar Tower Plants
Abstract
The steam generator failure is one of the main causes of unavailability of commercial solar tower plants. The superheater, as the point most susceptible to failure due to creep-fatigue damage, should be carefully analyzed to assure suitable reliability levels. For that reason, in this work, a novel superheater based on the header-type design is selected for a structural comparison study against to the conventional design consisting in a shell-and-tube hairpin-type superheater
