Blast furnace - Simple English Wikipedia, the free ...

A blast furnace is a special type of furnace for smelting iron from ore.Blast furnaces are very large. They can be up to 60 metres (200 ft) tall and 15 metres (49 ft) in diameter.The blast furnace is the biggest chemical reactor.Blast furnaces are also called high ovens.. A blast furnace is usually built with a steel case and bricks made of magnesium oxide or other refractory material inside ...

Blast furnace - Wikipedia

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure. In a blast furnace, fuel (coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygenenrichment) is blown into the lower section of the

Furnace - Simple English Wikipedia, the free encyclopedia

In American English, it is the name for a heating system in the house. British English usually calls such systems boiler, heater or kiln. There are industrial furnaces; these provide the heat so some process can take place. An example of such a furnace would be the use in metallurgic processing. Blast furnaces for example make iron

Smelting - Simple English Wikipedia, the free encyclopedia

A blast furnace is a tall vertical structure which is fed with coke, iron ore and limestone. When hot air is blown in the blast furnace, the coke will burn and reduce the oxygen off the ore, producing bare iron and carbon dioxide. The limestone will bind off any remaining bedrock. The iron melts in the hot temperature and is tapped off in ...

Coke (fuel) - Simple English Wikipedia, the free encyclopedia

Coke is a fuel used mainly in blast furnaces to reduce iron oxide to produce iron.It contains carbon, and is similar to coal.It is made from coal by cooking out things that are not carbon. Coke is a product of destructive distillation of coal. This is done in an airless furnace or oven at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F).

Iron - Simple English Wikipedia, the free encyclopedia

This happens in large containers called blast furnaces. The blast furnace is filled with iron ore, coke and limestone. A very hot blast of air is blown in, where it causes the coke to burn. The extreme heat makes the carbon react with iron ore, taking off the oxygen from iron oxides, and making carbon dioxide. The carbon dioxide is a gas and it ...

Bloomery - Wikipedia

A bloomery is a type of furnace once used widely for smelting iron from its oxides.The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom.The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into wrought iron. Blast furnaces, which produce pig iron, have largely ...

History China. In 31 AD, a Chinese engineer named Du Shi (Wade-Giles: Tu Shih) "invented the first water-powered bellows.This was a complicated machine with gears, axles, and levers that was powered by a waterwheel,". This invention aided the forging of cast iron smelted from the blast furnace.More extensive descriptions appear in literature of the 5th century.

Coal - Simple English Wikipedia, the free encyclopedia

Coal, when burnt, gives off almost a third more carbon dioxide per unit of energy than oil, and 80% more than natural gas.Almost half of the carbon dioxide from people is because of burning coal so it is the biggest single cause of global warming. Coal contributes to acid rain and smog, especially when burned without scrubbers.Burning coal releases toxic chemicals, including soot, mercury, and ...
