Exergy Analysis and Efficiency Improvement of a Coal Fired Thermal Power Plant in Queensland

Energy security and CO2 emission reduction are two major concerns of today’s world. Improv‐ ing efficiency of the energy systems is an essential option for the security of future energy and the reduction of CO2 emissions. With the growing prosperity of the civilization, our consump‐ tion of energy is growing very rapidly. Fossil fuels remain the world’s dominant primary energy supply, with its use as a versatile primary source of energy in power generation, transport and industry. However, we have finite sources of these non renewable fossil fuels and we are consuming them at a rate that cannot be sustained, leading to the risk on energy security in the future. The Intergovernmental Panel on Climate Change (IPCC), in its Fourth Assessment Report [3], identified carbon dioxide (CO2) emissions from burning of fossil fuels as the primary contributor to climate change. Therefore, the prudent use of energy is imperative and the importance of improving energy efficiency is now very well realized by all.
