'process of in-situ coating of pellets in an induration furnace'

摘要

The invention relates to an WPEP"s Waste Polymer Encapsulated Pellets are developed by effectively utilizing the waste polymers and carry over heat of pre-cooked pellets in an induration furnace during pelletizing. Waste polymer encapsulated pellets has shown strong character to reduce industrial dust emission as WPEP has 95% higher abrasion resistance and 10% higher cold compression strength as compared to the conventional pellets. WPEP usage in iron production will result in reduction of environmental polymeric solid waste and metallurgical fuel requirement. The process involves making design modification in the induration furnace where a polymer charging system is attached to the cooling zone 2 of the induration furnace and a swinging blanking plate is attached on the lower side to stop the air flow during charging of the shredded polymer pieces in to the cooling zone 2.
