Granulator coal injection has been practiced since 1982 at Scunthorpe Works, British Steel plc. The Works is world famous for its four Queens of Ironmaking, named Victoria, Anne, Bess and Mary. These four blast furnaces are capable of producing 4.1 million tonnes of hot metal per annum. The coal injection system was a joint development venture between British Steel and a local based company call Clyde Pneumatic Conveyors. After 14 years of operation and regulator use, Scunthorpe`s coal injection rates have risen to become among the highest in the world. Total coal injected stands at around 4 million tonnes and coal injection rates of greater than 200 kg/thm have been achieved. The furnace operation has remained smooth throughout and there have been no measurable detrimental effects upon the blast furnace performance. In fact quite the opposite with several benefits. This paper briefly describes the furnaces and the coal injection equipment. Operating results for a full twelve months are given and discussed as are aspects of the blast furnace operating practice enabling these injection rates to be achieved. In financial terms savings totaling around 14 million pounds sterling per annum have been realized through the use of blast furnace coal injection.
