Abstract
This work presents the performance analysis of the solar thermal hybridization of a typical biomass cogeneration cycle used by corn ethanol plants. A direct steam generation (DSG) parabolic trough solar field is considered as Concentrated Solar Power (CSP) technology and applied in parallel with the boiler on a fuel-saving operation strategy. The Ebsilon Professional is considered as the computational tool for the performance assessment and comparison of the cycle energy efficiency and fuel saved in a typical meteorological year on an hourly basis. The boiler part-load performance is also investigated. The results show the technical feasibility and possible advantages of applying CSP technology to the cogeneration of corn ethanol plants.
