Problems with elevated pressure in the blast furnace

Gas behavior in blast furnaces

“…The productivity of the centrifugal compressor is increased correspondingly, without increase in the steam con sumption. At the same time, the kinetic energy of the blast increases without increase in energy consump tion [22,23].…”

“…A recent analysis of the influ ence of elevated gas pressure on blast furnace perfor mance has shown that this approach does not intensify smelting and must not be regarded as a means to that end [23]. This is because the productivity of centrifu gal blast systems decreases with increase in the gas dynamic drag of the network in which the gas pressure increases, as noted in [22,23] …”
