dirty gases. These gases exit the top of the blast furnace and proceed through gas cleaning equipment where particulate matter is removed from the gas and the gas is cooled. This gas has a considerable energy value so it is burned as a fuel in the "hot blast stoves" which are used to preheat the air entering the blast furnace to become "hot blast".

The document describes how a blast furnace works to produce liquid iron from iron ore. Key points: 1) Iron ore, coke, and limestone are charged into the top of the blast furnace and preheated air is blown into the bottom. 2) Over 6-8 hours the materials descend and undergo chemical reactions to reduce the iron and remove impurities, producing liquid …

In Scunthorpe we have four blast furnaces named after four English queens – Mary, Bess, Anne and Victoria. Coke, iron ore, sinter and limestone are fed – or charged – into the top of the furnaces. A hot air blast of temperatures around 1,000°C is injected at the bottom of the furnace through nozzles called tuyeres. As the coke burns ...

A Blast Furnace Gas/air mixture at ambient temperature and pressure is explosive if the concentration of Blast Furnace Gas in the mixture is 30 – 70 vol.% [4]. The flammability limits of Blast Furnace Gas are shifted to the rich side compared to the flammability limits of natural gas (6.5 – 16.8 vol.%).

The blast furnace appeared in Europe in the 15th century when it was realized that cast iron could be used to make one-piece guns with good pressure-retaining properties, but whether its introduction was due to Chinese influence or was an independent development is unknown. At first, the differences between a blast furnace and a Stückofen were slight.

This blast furnace process is the oldest but still the main method to produce large quantities of molten raw iron, hot metal, and for steel making and foundry purposes. The early blast furnace had about a 6 m × 6 m square formed stone foundation and 6–8 m high walls of stone blocks. The upper half of the walls could be also made of timber.

The modern world uses shocking amounts of steel. The input requirements for 16th century blast furnaces were large. Though fuel consumption had fallen to roughly the level of the bloomery furnace (initially it used much more fuel than a bloomery), producing a ton of pig iron still required roughly 4.5-5 tons of charcoal, and 5.5-7 tons of …
