The reduction gas is injected through the bustle loed about 5 meters above the bottom of the shaft at 850°C and over 3bar pressure. The specific reduction gas flow is about 1200Nm3/ton of iron bearing burden charged to the shaft. The gas moves in the counter current direction to the top of the shaft and exits from the shaft at around 250°C.

Maurice, cooling towers don't 'vent steam'. Too much effort has been put into making sure that the water that makes the steam that drives the turbines doesn't fur up or corrode the system to waste it by venting to the atmosphere. The turbine steam is condensed and fed back to the boiler, it is a closed system.

The term "cooling tower" is used to describe both direct (open circuit) and indirect (closed circuit) heat rejection equipment. Cooling towers are heattransfer units, used to remove heat from any watercooled system. The cooled water is then recirculated (and thus, recycled) back into the system. Since the process water is recirculated, the mineral concentration increases as a result of the ...
