Coal Combustion in the RacewaYand Tuyere of Blast Furnace. Injection of pulverized coal into a blast furnace is an important technique from the viewpoints of assuring stable blast furnace operation reducing costs and allowing more latitude in selection of resourc The high-rate injection of pulverized coal is a particularly effective meanswhich can avoid the coke oven re-construction and meet

RECYCLING OF FLUE DUST INTO THE BLAST FURNACE

The results from studies made in a laboratory rig and in a charcoal furnace by Gudenau et al. concerning the injection of iron-oxide containing dust has established that hematite can be reduced to metallic iron within the short residence time in the raceway. The experiments also indi ed combustion of low volatile coal was promoted by the addition of a certain amount . of dust to the mixture

Blast furnace efficiency enhancer for pulverized coal

Download Citation Blast furnace efficiency enhancer for pulverized coal injection To improve the performance of pulverized coal injection PCI , trials were conducted with combustion enhancers

Development of Waste Plastics Injection Process in Blast

detected in in-furnace, the decomposition products of plastics in the blast furnace top gas and dust were the same as that of pulverized coal injection. The preparation method of plastics had an influence on the combustion and gasifi ion behavior in the raceway. The coarse plastics gave high combustion and gasifi- ion efficiency compared with fine plastics and pulverized coal, and CO
