| Abstract: | The global steel production has been growing for the last 50 years,from 200Mt in 1950s to 1240Mt in 2006. Iron and steel making industry is one of the most energy-intensive industries,with an annual energy consumption of about 24 EJ,5% of the world's total energy consumption. The steel industry accounts for 3%-4% of total world greenhouse gas emissions. Enhancing energy efficiency and employing energy saving/recovering technologies such as coke dry quechning (CDQ) and top pressure recovery turbine (TRT) can... |
