what are blast and crucible furnaces
A cupola furnace is not the same as a crucible furnace. A cupola furnace is a type of melting furnace used mainly for iron melting, while a crucible furnace is a type of melting furnace that uses a ceramic or graphite crucible to contain the molten metal. The names reflect the different structures and functions of the two types of furnaces.
Two common contaminants found in water used to cool blast furnaces are iron and sulfur. Iron can accumulate in the water from the contact with the metal parts of the furnace, while sulfur can be present due to the combustion of sulfur-containing fuels used in the furnace operation.
Coal is unsuitable for charging directly into a blast furnace because it contains impurities like sulfur and ash that can negatively affect the quality of the iron produced. When coal is used as a fuel in the blast furnace, it can lead to increased levels of impurities in the iron, affecting its properties. As a result, coke, which is a cleaner form of coal, is typically used in blast furnaces for iron production.
how does the blast furnace maintain the heat ?what is the function of CaCO3 ?how the slag protect the molten iron ?why does iron flow down to the bottom /how does the slag and molten iron get seperated ?what is use of waste gas /what is main impurity of iron in blast furnace ?
Some will give credit to Sir Henry Bessemer invented the modern day blast furnace in 1855. However, if you look historically the Chinese invented the blast furnace. By at least the 4th century the Chinese have developed blast furnaces to obtain cast iron from iron ore. This was 1200 years before the first blast furnace showed up in Europe.

because round (mushroom furnaces) have limit in diameter of furnace, rectangular (Rachette furnace) can solve those problems

Depending on the scale, it could be a crucible, a furnace or (only in the case of iron) a blast furnace.

Blast furnaces require you to go and stick dil*o up your vag, then lick my long john and give a fellatio to your cousin.

Heat loss in a blast furnace can occur through various mechanisms, such as conduction, convection, and radiation. It is crucial to minimize these losses to ensure efficient operation of the furnace and optimize energy consumption. Various insulation materials and refractories are commonly used to reduce heat loss in blast furnaces.
