Numerical Analysis on Blast Furnace Performance under Operation with Waste Plastics Injection and Top Gas Recycling

摘要

Injection of hydrogen bearing materials and top gas recycling are proposed to reduce energy consumption and lower environment load for blast furnace process, through the enhancement of hydrogen reduction and fixing of CO_2. The combination of these two technologies further strengthens the concentration of hydrogen in the furnace and contributes to higher efficiency. In order to investigate the performance of blast furnace under waste plastics injection and top gas recycling, numerical evaluations were made in this study.
