Blast Furnace and Stoves | Eurotherm by Schneider Electric

The hot blast air is produced by passing cold blast air through preheated chambers or ''stoves'', and heating the air to above 1000°C. The stove is first heated up by burning gas and combustion air within the chamber and allowing the heat to be absorbed into the brickwork, or ''chequerwork''. This mode is calledon-gas.

Making iron & steel

Blast furnace. Before iron ore can be used, oxygen must be removed from it. Known as ''reducing'', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic ...
