AIMS AND CONTENT

LEARNING OUTCOMES

The course presents the current situation related to energy generation plants (traditional and innovative
plants) with special attention to pollutant emission decrease and conversion efficiency increase.
In the field of the course topics, aspects will be developed on alternative fuel utilization, component and plant
performance, their environmental impact and current technological and economic aspects.

Teaching methods

48 hours of lectures, laboratory and numerical practices

SYLLABUS/CONTENT

Combustion and pollutants formation processes

Conventional fuels and their specifications. Air required for combustion, air-fuel ratio and fuel heating value. General aspects and classifications of combustion processes. Pollutants formation processes and their effects on human health and environment.

Boilers and steam generators: fundamentals and components

Historical hints. Boiler classification and components. Thermal balance and heat transfer in boilers. Innovative concepts: boiler Once-Through and super-critical. Example of steam locomotive.

Combined cycles and cogeneration

Combined gas and steam cycles. Heat recovery steam generator. High efficiency cogeneration and district heating. Biomass boilers for district heating.

Pollutant emissions and abatement technologies in energy systems

Pollutant types, properties and measurement units. Pollutant prevention techniques applied to gas turbine combustors. SOx abatement systems. NOx abatement systems.

Modelling and simulation of energy systems

Lumped-parameter and modular simulation models. Numerical analysis of energy systems. Practical exercise with WTEMP software.

Wind energy

Horizontal and vertical axis wind generators. Wind assessment, wind park energy production estimation. Environmental impact of wind mills.

Internal combustion engines (ICE)

ICE classifications and applications. Indicated diagrams, indicated and brake mean effective pressure. Engine power correlations. Combustion processes in spark ignition and compression ignition engines. Constant speed and constant load curves, engine performance maps. ICE supercharging and turbocharging. ICE generator sets. Heat recovery in Diesel engines. Cogeneration plants based on biogas fuelled ICE. Use of bioethanol and biodiesel in ICE: operational issues, influence on performance and emissions.
