introduction：80Since the ages，Britain、France、A few blast furnaces in the United States use the blasting process。The average particle size of granular coal is approx０.６ｍｍ，Maximum particle２－３ｍｍ。１９９１years１０month，The monthly average injection of granular coal from Victoria blast furnace at Scunthorpa, UK, was achieved２０１ｋｇ／ｔiron。At this time, the coal coke replacement ratio is still relatively high（０.９３－１.０ｔ／ｔ），The dust content of the stove top gas remains at７ｋｇ／ｔIron left and right（It shows that all the grain coal is digested in the furnace），Blast furnace operation straight。Due to the injection of granular coal with a low mill investment，Low power consumption and coal production、Good advantages of spray safety，
