4A1605 Sustainable Power Generation,

period 1-2, 2004

Introduction

The courses Energy Technology, 4A1603 and 4A1602, was an introduction to the field of Energy Science. Different aspects from energy utilisation and generation were brought up in brief. Orientation was given in power and refrigeration cycles, the technologies, efficiencies and environmental aspects. The energy situation in the world was discussed from an overall perspective.

In this course, Sustainable Power Generation, the power generation part will be treated more in detail, starting at the steam cycle power plant. The course can be divided in different blocks, where each block represents an important knowledge base in order to be able to design and assess a sustainable power generation system. The word “sustainable” implies best technology, as high efficiencies as possible, as good environmental values as possible, an acceptable living standard for people but also economical durability.

0.2 Introduction to Sustainable Power Generation (1h)

The word "sustainable" implies many things within the energy field. A system is sustainable if it is environmentally, economically and technically sustainable, with a high availability. For example, hydropower is regarded as a renewable energy source, it gives no emissions while producing power, it is an old and well-known technology, and has a very good availability. Hence hydropower is able to be a sustainable system, depending on the size and which technology is utilised.

Wind power on the other side, is as well environmentally sustainable, but is very expensive to install and only produces power when it is blowing. Hence from economical and availability viewpoints, it is not sustainable.

This lecture will introduce to Sustainable Power Generation concept and will also give an overview of different power generation methods.

2.1 Combustion, Fuels and Emission Control (6h)

Combustion is the phenomenon for releasing fuel bound energy to hot flue gases, which can directly or indirectly generate power. But what happens in the combustion process and how much flue gases are released burning one kilogram of wood or coal? What is the flue gas composition and how much energy is lost with the flue gases in a boiler? Different fuels are brought up as well.

Combustion processes always give rise to different kind of emissions that affect the environment in various ways. Some also affect the health of people.

The different emissions will be brought up as well as different separation and prevention techniques for the emissions dust, SOx , NOx and CO2 .

2.2 Boilers and Furnaces (6h)

The heart in a thermal power station is where fuel is converted into thermal energy, i.e. a boiler or in a gas turbine combustor. There are different types depending on pressures and temperatures required as well which fuel is used. How is a boiler constructed in general? Traditional as well as more modern boilers are gone through, for example the fluidised bed. Also gas turbine combustion chambers are brought up.

3.2 Environmental Aspects of Nuclear Power (4h)

There are several factors that determine whether given source of energy is sustainable or not. In modern approach these factors include not only the source availability relative to the rate of use, but also environmental effects, the question of wastes, safety, and the broad and indefinite aspect of maximizing the options available to future generations. This lecture will focus on environmental aspects of nuclear power, including the nuclear fuel availability and the nuclear waste treatment. Typical fuel cycles of present and future nuclear power plants will be described and analyzed from the sustainability point of view. New options, which will be a part of future nuclear power development, like hydrogen generation and water desalination, will be presented. Finally, evaluation of costs for the nuclear energy will be shown.

3.3 Safety of Nuclear Power Plants (4 h)

Concern for safety is an essential aspect of engineering design in general and in the nuclear field in particular, where unusually stringent measures are adopted to assure the safety of the public and the people working in the plants. This concern is caused by the fact that highly radioactive (and potentially hazardous) fission products are generated in the fuel during operation of nuclear power plants. Generally speaking, the goals of nuclear power plant safety are to reduce the probability of an accident that could lead to the escape of radioactivity from the plant and limit the extend of the radiological hazard in an event that such an accident should occur. In the present lecture the safety measures currently applied in nuclear power plants will be described.
