Energy and Exergy (2E) Analysis of an Optimized Linear Fresnel Reflector for a Conceptual Direct Steam Generation Power Plant
Abstract
Direct steam generation is a promising alternative to conventional HTF for solar thermal power plants, and the optical equivalence of parabolic through collectors and linear Fresnel reflector demonstrated by several authors has led to the proposal of the integration of direct steam generation in linear Fresnel reflector systems for Steam Rankine power plants; as the Puerto Errado (Portugal), Kimberlina (USA) or Liddell (Australia). With this background, in the present paper a 2E analysis (energy and exergy) of several configurations of conceptual solar power plants with Fresnel reflectors and direct steam generation, coupled to a Steam Rankine power cycle, is developed in order to establish a reference for a future implementation of this technology and show its viability against parabolic trough plants in México.
