. A simplified diagram of a Blast Furnace is drawn below. A typical blast furnace may be up to 32 metres in height and 10 metres in diameter. They have thick steel sides, lined with refractory bricks, to ensure that heat is not lost. Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. My furnace internal fluid temperature is order of magnitude higher than it suppose to be. I dont think I am injecting too much fuel or oxygen. My residuals are pretty good (all -4 ~ e-7). Thanks Jee. November 18, 2022 at 11:00 am. Rob. Ansys Employee. Fig 1 Zones of a blast furnace. There are generally four distinct types of solid flow regions in the BF. These are (i) plug flow region which is associated with the uniform velocity of burden descend from stock-line and position just above the cohesive or melting zone, (ii) stagnant flow region (dead-man) which is a discontinuous mass of partially reacted coke particles in the centre part of.

Abstract. Blast furnace reactions play an important role in BF production. Heat and reducing gas are generated in tuyere zone. Reducing gas goes upwards, solid charge materials come down, and counter-current interaction reactions take place at the upper zones. Slag-metal reactions take place at the hearth.

Sep 11, 2020 · Blast furnace Uses iron ore as the source of material and coke as the main fuel and sources of energy. Melts iron ore and coke so it can produce pig iron high in carbon content and this is then is fed into a converter to remove impurities. Needs a high investment in facility development and takes up a large space. Easier to produce clean steel..
