Panagiotis Grammelis Emmanouil Karampinis in Fuel Flexible Energy Generation 2016 2322 Blast furnace gas Blast furnace gas is produced during the iron oxide reduction in blast furnace iron making in which iron ore coke and limestone are heated and melted in a blast furnace and is an indigenous process gas of the steelworks industry Pugh et al 2013
Blast furnace technology 3 hot metal and pig iron produced by last b furnaces stand for 60 of all steel products which the worlds population consumes last urnace ironmaking is a traditional technology which has been steadily f b
Mar 29 2018Role of coke in a blast furnace are following 1 Coke is source of heat in blast furnace 2 Coke act as a reducing agent for iron ore 3 Coke provide permeability to the burden in blast furnace due to which gas pass in counter direction
In a blast furnace iron ore reacts with hot coke to produce pig iron The sintering or pelletising process prior to the blast furnace operation is added to allow blending of iron ores and also to control the size of the blast furnace feed Sintering or pelletising improves the blast furnace
The main products of blast furnace smelting are pig iron as well as byproduct blast furnace slag and blast furnace gas In order to better solve the problem of screening under the blast furnace tank WINNER has developed a new product WFPSXC after the three generations of posite frequency vibrating screen The application of the three
In blast furnace ironmaking coal is not as strong as coke and crushing will cause a decrease in the permeability of the blast furnace The calorific value and carbon content of some anthracite coals are higher than coke but there are more harmful impurities such as phosphorus and sulfur in coal
Blast furnace process The iron ore concentrate is now mixed and ready for the pelletizing process Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets in much the same manner that one rolls a snowball to make a pellet about the size of a marble between 14 and 12
The water content in coke is practically zero at the end of the coking process but it is often water quenched so that it can be transported to the blast furnaces The porous structure of coke absorbs some water usually 36 of its mass In more modern coke plants an advanced method of coke cooling uses air quenching
Coke is created by heating metallurgical coal to around 2000 degrees Fahrenheit The coking process takes about 12 to 36 hours in the oven to plete according to the World Coal Association After being taken out of the oven the coke is cooled with water or air to before it is either placed into storage or is put directly to the blast furnace
