SUMMARY:Blast furnace top gas generation in times of energy shortages
DESCRIPTION:In times of energy crisis, shortage of natural gas and geopolitical challenges the constant supply of electrical energy presents a great obstacle. During the last years, prices for electricity and natural gas were under constant fluctuations and even stable energy supply for households cannot be guaranteed anymore. Recently blackout plans were developed for the worst cases.In integrated steel works, the blast furnace (BF) and the coking plant contribute to the energy network.
Beside hot metal and slag, the top gas of the BF is used as an energy source for various processes e.g. heating of hot stoves, coking plant or hot rolling mills. Surplus amounts of gas are used in the nearby power plants to produce electrical and thermal energy for district heating of surrounding households. For tk SE the produced electric energy covers more than the consumption of the entire plant and supplies the surplus to the electrical grid. This raises the question if this surplus can be further increased to save other fossil resources and help the electrical grid in times of power shortages.
A project has been started to investigate possible operating conditions to increase either the amount of top gas or the calorific value of the BF top gas. This paper will show the theoretical and practical results of this project and discuss advantages and disadvantages of these parameters.
