Thermal optimization of solar biomass hybrid cogeneration plants

摘要

Thermal optimization and performance matching of subsystems in solar biomass hybrid plant are investigated. The plant incorporates solar collector field, multiple fuel boiler, steam turbine, deaerator and economizer units. The solar field consists of line focus parabolic trough collectors. The thermal model is used for comparative study of various variations of parabolic trough collectors; LS3, Euro Trough (ET) and Duke solar excel over others. The matching of the output heat Q_u and the temperature to the feed water conditions indicate that ET is the most suitable for the application; its inlet temperature requirement also matches the energy balance of the deaerator.
