   A tuyere, seen from inside a blast furnace An old tuyere in Nok, Nigeria. A tuyere or tuyère (French pronunciation:; English: / t w iː ˈ j ɛər /) [1] [2] is a tube, nozzle or pipe allowing the blowing of air into a furnace or hearth. [3] Air or oxygen is injected into a hearth under pressure from bellows or a blowing engine or other

3. Krupp–Renn process - Wikipedia

   en.wikipedia.org/wiki/Krupp–Renn_Process

   In 1960, a Krupp-Renn furnace using low-grade ore yielded 100 kilotons of iron annually, [28] while a contemporaneous modern blast furnace produced ten times as much cast iron. [ 31 ] Direct reduction processes employing rotary furnaces frequently face a significant challenge due to the localized formation of iron and slag rings, which sinter ...

4. Forced-air gas - Wikipedia

   en.wikipedia.org/wiki/Forced-air_gas

   Plastic outlet for a condensing natural gas hot air furnace. Not all the water vapor is condensed; some freezes at the outlet. This vent contains a coaxial combustion air inlet pipe. Blowing snow can block the pipe, but the furnace control can detect this condition and prevent the burner from starting.

5. Blast furnace - Wikipedia

   en.wikipedia.org/wiki/Blast_furnace

   In a blast furnace, fuel , ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward.

6. Fitzroy Iron Works - Wikipedia

   To run the trial of this coal, the blast furnace was lit again—possibly in late 1873, more probably during 1874—but it was not bought into successful production. [ 124 ] [ 125 ] A photograph, that has been identified as being taken 'c. 1873', does appear to show the furnace and at least one of its stoves in operation, or at least emitting ...

7. Blowing engine - Wikipedia

   en.wikipedia.org/wiki/Blowing_engine

   The very first blowing engines were the blowing houses: bellows, driven by waterwheels. Smelters are most economically located near the source of their ore, which may not have suitable water power available nearby. There is also the risk of drought interrupting the water supply, or of expanding demand for the furnace outstripping the available ...
