SOLAR AND BIOMASS POWER PRODUCTION AY 2020-21 27th August 2021 Prof. Giampaolo Manzolini Time : 40 min Ins tructions for the examination: 1) Clearly indicate your name on all the sheets you will deliver. 2) The s core refers to exercis es done in a comprehens iv e manner with exact numerical res ults . Numerical res ults correct but not accompa- nied by explanations will not be tak en into account. The final s core can be normalized acc ording to the av erage res ults . 3) Answer briefly and clearly only to the as k ed ques tions . Calculations and explanations which do not res pond to the ques tions will not be cons idered for evaluation even if correct. 4) Talk ing with colleagues and / or cheating will caus e the cancellation of the ex am. 5) Al l the needed data for the resolution of exercis es lies on this paper. It is NOT ALLOWED to use material other than this (e.g. book s , clipboard etc.). 6) Not all the provided inputs are neces s ary for the problem s olving Each answer shall fit in one A4 page Question A) PV: Draw a PV cell pointing out the different layers, the importance of each layer and the movement of the electrons Question B) CSP: Discuss the different options (at least 3) of hydraulic circuit in a solar tower in the norther emisphere, pointing out pro and cons of each configuration Question C) Biomass: what conversion process would you adopt considering a biomass with the following characteristics MC 50%, LHV 10 MJ/kg, lignin 50%, hemicellulose 30% and cellulose 20%. Draw a schematic of the conver- sion process.
