96187 - SISTEMI PER LE ENERGIE RINNOVABILI E PER L'AMBIENTE M

Learning outcomes

The aim of the course is the study of the environmental impact caused by the use of energy systems for the production of thermal and electrical energy and their management aimed at minimizing these emissions.

Course contents

The course offers a broad overview of the various technical issues related to energy and the environment.

Introduction to global environmental change.

• heat released into the ambient by energy systems.
• closed steam cycle systems: architectures for cooling the condenser.
• air pollution: type of gaseous and solid emissions due to fossil fuel combustion in energy systems (NOX, SOX, CO, CO2, PM, HC). Description and analysis of main combustion parameters affecting generation of pollutant emissions. Methods and strategy to limit the emission into the ambient inside the combustion chamber and at the end of the process. Impact on the  environment of gaseous and solid emissions.
• Environmental analysis of gas turbine and combined cycle energy systems.
• Environmental analysis of steam cycle energy systems.
• Compression refrigeration cycle for generation of  cooling energy and environmental impact of refrigeration fluids. 
• Renewable energies: Bio-Energy and Waste-to-Energy Technologies; geothermal energy. 
• Organic Rankine cycles for generation of electrical energy exploiting low-grade enthalpy fluxes.
• hydrogen: main properties of H2 compared to natural gas. Methods and processes for generation of hydrogen.

Teaching methods

Classroom Lectures. Students are encouraged to attend classes in order to improve their final learning outcomes. The course attendance is not mandatory and it does not have influence on the final examination score.

Assessment methods

The assessment of the learning outcomes will be performed through an oral examination (1 hour approximately) including, typically, two open-end questions.

The minimum score is 18/30, the maximum is 30/30 with honors.

The minimum score is not achieved if large deficiencies in learning outcomes are exhibited: i.e., missing main hypothesis, miss any knowledge of machinery working principles and/or working cycles, etc.

Examinations schedule is available in advance on the University of Bologna web site AlmaEsami. Students willing to take the exam must join to the exam student list on the web site AlmaEsami.

Students are required to show their own ID before taking the exam.

Teaching tools

Course is given by teaching classes and students are encouraged to attend in order to improve the learning process and learning outcomes.
