What is the use of a tuyere?
Tuyeres were also used in smelting lead and copper in smeltmills. Modern blast furnaces may have up to 42 tuyeres, through which the hot blast is injected in the furnace. They are usually made from copper and cooled with a water jacket to withstand the extreme temperatures.
Which injection is used for iron ore?
Iron dextran injection is used to treat iron-deficiency anemia (a lower than normal number of red blood cells due to too little iron) in people who cannot be treated with iron supplements taken by mouth. Iron dextran injection is in a class of medications called iron replacement products.
What is tuyere velocity?
The input rate of blast per tuyere is about 12 Nm3/min at 1.2 bar. This gives tuyere tip velocities of 80–120 m/s. Blowing rates above 17 Nm3/min per tuyere cause slopping of matte and slag from the converter.
What substance is fed in through the tuyeres?
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 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 …
What is a tuyere in blast furnace?
Tuyeres — an old French term for “nozzles” —are used in many metallurgical vessels, including blast furnaces, which smelt iron, and cupolas, which melt iron, to direct the air blast into the furnace. Because they are in such a hot and chaotic environment inside the furnace, they are prone to premature failure.
How is iron injection given?
How are iron injections given? Iron injections are usually given as a slow drip into your vein (called intravenous infusion). A needle is placed into the vein, in the back of your hand or arm, so the iron infusion can go directly into your blood stream. It will take at least 15 minutes for the infusion to go through.
What is a bustle pipe?
Definition of bustle pipe : the outside pipe that supplies the blast to the tuyeres in a blast furnace.
Does iron injection increase hemoglobin?
One way of treating anemia is with intravenous iron, which is delivered into the vein through a needle to increase the levels of iron and hemoglobin in the body.
