In recent years, mainly in China, fabric filters were installed frequently for second stage de-dusting of blast furnace gas. 6,7) The dry de-dusting process offers several advantages. First, a downstream top gas recovery turbine provides a higher energy output due to the higher temperature of the purified blast furnace gas and lower pressure drop of the cleaning system. 8,9,10) Secondly

Dry Granulation of Blast Furnace Slag Steel360 News

Liquid slag produced in a blast furnace (BF)is at a temperature of around 1500?C and has a sensible heat of around 400Mcal/ton. BF slag is rich in CaO, SiO2, Al2O3, and MgO which are similar to the components of Portland cement. When this liquid BF slag is cooled fast enough then the solidified slag has a large percentage of glassy phase with high cementations activity and hence it can be used

Dry flue dust has a negative effect on briquette quality in terms of cold strength, and the cost of briquette production has increased. The results from studies made in a laboratory rig and in a charcoal furnace by Gudenau et al.

BLAST: Basic Local Alignment Search Tool

The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.
