How do you think the blast furnace got its name?
the blast furnace got its name , because its bottom which is called a furnace blows hot air to go up.
How tall is a blast furnace?
A blast furnace typically stands between 70 to 100 feet tall, with some reaching heights of up to 150 feet. The height of a blast furnace is crucial for its efficiency in producing iron, as it allows for the proper distribution of materials and gases throughout the furnace. The tall structure also helps create the necessary conditions for the chemical reactions that take place within the furnace to produce molten iron.
Is boiler and furnace are same?
No, furnaces are forced air heat. Boilers are hot water heat.
What are the differences between boilers and burners?
A burner is the part of the boiler that creates and controls the flame that heats the water. If you meant difference between a boiler and a furnace, a boiler makes hot water and a furnace makes hot air.
How nut coke is charged in blast furnace?
According to steel.nic.in; Coke Rate is measured in Kgs of BF Coke consumed per tonne of Hot Metal produced in the Blast Furnace(Kg/THM). By convention, this excludes coke (nut/pearl coke) mixed with sinter etc. Introduction of high quality coke to a blast furnace will result in lower coke rate, higher productivity and lower hot metal cost. This principal is followed by many private chemical firms like Coke Oven Consultants and so on.
What creates the air blast in a blast furnace?
Hot air under pressure
What Is A Blast Furnace?
A blast furnace is a forge in which ore is smelted to meal, being intensified by a blast of hot air.
How do you think the blast furnace got its name?
the blast furnace got its name , because its bottom which is called a furnace blows hot air to go up.
Why is hot air blasted into the furnace?
Hot air is blasted into the furnace to increase the temperature inside the furnace quickly by providing additional oxygen for combustion and promoting efficient fuel burning. This helps speed up the metal production process and maintain a consistent temperature for melting and refining.
Why is a blast furnace called blast furnace?
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 ?
What goes into a blast furnace?
A blast furnace typically contains iron ore, coke (fuel derived from coal), and limestone. These materials are layered in the furnace and hot air is blown in at the bottom to create a chemical reaction that produces molten iron.
What is top pressure in blast furnace?
Top pressure in a blast furnace refers to the pressure of the gases at the top of the furnace. Maintaining the appropriate top pressure is crucial for the efficient operation of the blast furnace and influences factors such as the flow of gases in the furnace and the quality of the hot metal produced.
How does the blast furnace maintain the heat?
The blast furnace maintains heat through the combustion of coke (a type of coal) with hot air blown in at the bottom. This creates a high temperature that allows the iron ore to melt and collect at the bottom of the furnace. The heat is further sustained by the chemical reactions occurring within the furnace.
How blast furnace is heated?
A blast furnace is heated using hot air or hot gases blown into the lower section of the furnace. This process helps to combust the coke (fuel) and create high temperatures necessary for the chemical reactions to convert iron ore into molten iron. The combustion of coke also produces carbon monoxide, which acts as a reducing agent in the process.
What is the difference between hot air oven and muffle furnace?
hot air oven heats content in it and where as furnace heats air around it
Why four uptake is given in blast furnace?
The purpose of the four uptakes in a blast furnace is to allow for the passage of hot gases produced during the iron smelting process. These gases include carbon monoxide, carbon dioxide, and nitrogen, which are byproducts of the combustion of coke with hot air. The uptakes help to release these gases from the top of the furnace and direct them to the gas-cleaning system for processing and reuse in the process.
How much coke required for production of one ton hot metal in blast furnace?
The amount of coke required for the production of one ton of hot metal in a blast furnace can vary, but on average, it takes about 800-1000 kilograms of coke per ton of hot metal. Coke is used as a fuel and reducing agent in the blast furnace to help convert iron ore into molten iron.
