11. Pellet reduction properties under different blast furnace operating conditions
Sammanfattning : One of the aims of modern blast furnace (BF) ironmaking is to reduce coke consumption. One way is to increase the injection of reduction agents, such as pulverized coal. An increase in pulverized coal injection rate (PCR) will affect the blast furnace process and the conditions for iron oxide reduction. LÄS MER
12. Improving Wood Fuel Pellets for Household Use : Perspectives on Quality, Efficiency and Environment
Sammanfattning : Bioenergy is one of many contributors to reducing the use of fossil fuels in order to mitigate climate change by decreasing CO2-emissions, and the potential for biofuels are large. The wood fuel pellets are a refined biofuel made of sawdust, which is dried and compressed to achieve improved fuel and transportation properties. LÄS MER
13. Wood Fuel Pellets: Sawdust Drying in the Energy System
Sammanfattning : In 2004, the amount of wood fuel pellets used in Sweden was 1 256 000 tons, it was mostly used in large scale burning for district heating. Over the last 10 years, a significant increase in pellet production has occurred and today the preferred raw materials for pellet production, i.e., dry sawdust and wood shavings, are insufficient.

14. Drying of iron ore pellets : analysis with CFD
Sammanfattning : Iron ore pellets are a highly refined product and for companies such as LKAB it is important to constantly improve the pelletization in order to enhance production and improve product quality. A long term goal has been established to develop and considerably refine tools and techniques with which the drying zone of a pelletizing plant can be optimized. LÄS MER
15. Studies on the cold bonded briquettes of iron and steel plant by-products as burden material for blast furnaces
Sammanfattning : During the various stages of iron & steel production a number of iron bearing by-products are generated. These by-products can be made into cement bonded agglomerates for use as burden material for blast furnaces. LÄS MER
