Blast furnace

Process Ore limestone and carbon in the form of coke are put into the top of the blast furnace in layers At the same time hot air called wind is blown inside the furnace Special nozzles called tuyeres are used to put the air in the furnace The nozzles are at the bottom of the furnace This process is called blasting It is why it is called a blast furnace

Blast furnace

The blast furnaces used in the Imperial Smelting Process (ISP) were developed from the standard lead blast furnace but are fully sealed This is because the zinc produced by these furnaces is recovered as metal from the vapor phase and the presence of oxygen in the off-gas would result in the formation of zinc oxide
