1. 1. Alkali Circulation in the Blast Furnace - Process Correlations and Counter Measures

   University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

   Author : Joel Carlsson; [2018]
   Keywords : Alkali; coke; experimental blast furnace; top gas; mass spectrometry; multivariate analysis;

   Abstract : In blast furnace ironmaking one major challenge is to control and measure the alkalis circulating and accumulating in the blast furnace (BF). Alkali enter the BF with the primary raw material and will form a cycle where it is first reduced to metal at the lower parts forming gas. READ MORE

3. 2. Alkali Control in the Blast Furnace – Influence of Modified Ash Composition and Charging Practice

   University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

   Author : Jenny Olofsson; [2017]
   Keywords : Experimental blast furnace; coke; coke ash; reactivity; characterization; catalyst; coke degradation;

   Abstract : The enrichment of alkali in the blast furnace has been proven to be a catalyst of coke gasification and is thus a key parameter in the degradation of coke. Alkali also directly destroys the carbon structure, increases the risk of scaffold formation, increases the load and attacks the refractory. READ MORE
