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

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

Blast furnace gas Wikipedia

Blast furnace gas (BFG) is a by-product of blast furnaces that is generated when the iron ore is reduced with coke to metallic iron.It has a very low heating value, about 93 BTU/cubic foot (3.5 MJ/m 3), because it consists of about 60 percent nitrogen and 18-20% carbon dioxide, which are not flammable.The rest is mostly carbon monoxide, which has a fairly low heating value already and some

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

Explosion Wikipedia

An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel via shock waves. Subsonic explosions are created by low explosives through a slower combustion process known as

Metallurgical furnace Wikipedia

A metallurgical furnace, more commonly referred to as a furnace, is a device used to heat and melt metal ore to remove gangue, primarily in iron and steel production. The heat energy to fuel a furnace may be supplied directly by fuel combustion, by electricity such as the electric arc furnace, or through induction heating in induction furnaces.There are several different types of furnaces used

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

Limestone Simple English Wikipedia, the free encyclopedia

Uses Edit. Limestone is hard enough to resist weathering but usually soft enough to be worked (cut and carved) by stonemasons. It is used for building material. Limestone, particularly Portland limestone, became popular in the 19th and 20th centuries for building things such as churches, banks and houses.However, acid rain does slowly erode limestone.

Cupola furnace Wikipedia

Cupola furnaces were built in China as early as the Warring States period (403–221 BC), although Donald Wagner writes that some iron ore melted in the blast furnace may have been cast directly into molds.During the Han Dynasty (202 BC 220 AD), most, if not all, iron smelted in the blast furnace was remelted in a cupola furnace; it was designed so that a cold blast injected at the bottom
