The Principle of Blast Furnace Operational Technology and ...

In 1983 we started pulverized coal (PC) injection at the Kakogawa #2 BF and Kobe #3 BF to supplement the capacity of the coke furnace and to reduce energy cost. The PC injection adopted the concepts and theories of combining oxygen rich blowing and fuel injection, each of which had been established by the 1970s. Subsequently, researches on the movement of burden materials in the .

Char Formation by Coal Injection and Its Behavior in the ...

Blast furnace (BF) coal injection became a routine practice among European BFs; roughly, 40% of total energy required for the process is covered by auxiliary reducing agents. Pulverized coal (PC) remains the most commonly used auxiliary reductant. The key trend is increasing PC injection rates; over 200kgtHM 1 PC on an annual basis is no rarity any more. Despite numerous measures for ...

Blast Furnace Granular Coal Injection Project

Operating blast furnaces with coal injected directly through the tuyeres into the combustion zone as a supplemental fuel will result in reduced coke consumption, thereby decreasing the environmental emissions associated with cokemaking. The environmental problems normally associated with the combustion of coal will also be. virtually eliminated by direct injection of coal into the blast ...

Method of injecting pelletized coal through blast furnace ...

Blast furnace injection of pelletized coal eliminates any necessity for such a restrictive selection of coals and for the first time makes it possible to use a free flowing, low sulfur pelletized coal for blast furnace injection. This is accomplished by the method of grinding, separating and pelletizing to rebuild the very fine particles of ground coal to produce rounded low sulfur pellets of ...

Blast Furnace Granulated Coal Injection System ...

Blast furnace injection of coal will allow domestic integrated steel producers to maintain production while minimizing their dependence on coke. The BFGCI process uses granular coal, which is cheaper to produce than the pulverized coal required by many other blast furnace coal injection technologies. The BFGCI technology has characteristics that make it very attractive for appliion in the U ...
