its used a fuel , but has less calorific value as the carbon monoxide percentage is less which is the main combustible gas in the b.f gas. its used in heating the blast of hot air in the blast furnance itself and also can be used in rolling mill, sinter plant, and many more where you need heating

What is refractory consumption per ton in induction furnace?
Refractory consumption per ton in an induction furnace refers to the amount of refractory material used during the melting process, typically measured in kilograms per ton of metal produced. This consumption can vary based on factors such as the type of refractory used, the operational practices, and the specific characteristics of the charge materials. Generally, the refractory consumption ranges from 5 to 20 kg per ton of metal, depending on the furnace design and operational conditions. Minimizing refractory consumption is essential for cost efficiency and operational effectiveness.
Can creosote oil replace furnace oil as fuel?
Creosote oil can technically be used as a substitute for furnace oil, but it is not ideal due to several factors. Creosote is primarily a wood preservative and has different combustion properties, which may lead to inefficiencies and increased emissions. Additionally, its use may be restricted or regulated in many areas due to health and environmental concerns. Therefore, while it may serve as an alternative in specific contexts, it is not a straightforward or universally acceptable replacement for furnace oil.
Operation of a combined cycle power plant?
A combined cycle power plant has multiple thermodynamic cycles. This increases efficiency. For example, a gas turbine can be used to produce electricity, but only about 40% of the heat is actually converted in the process. 60% of the heat is lost, and in a single cycle plant would be considered waste heat. In a combined cycle plant, that waste heat could be used to drive a second, steam turbine to produce more electricity. In such a case, the efficiency could be increased from 40% to nearly 60%. It is possible to go further. The waste heat from the combined cycle electric plant can be used to heat buildings, for instance, increasing overall efficiency to more than 65%. This is called Cogeneration.
What is drain hub and why used in oil refinery?
A drain hub is a component in an oil refinery that collects and directs the flow of liquids, such as water and hydrocarbons, away from equipment and processes to prevent contamination and maintain operational efficiency. It helps manage the drainage of waste products and prevents the accumulation of potentially harmful substances. By facilitating proper drainage, it contributes to safety, environmental compliance, and the overall efficiency of refinery operations.
Can the slag on a blast furnace be used in concrete or cement?
Slag from a blast furnace is usually ground down and used as a cement substitute as it is re-use of a waste product - it is not used on its own in concrete as the chemical reaction will not produce the same strength as proper cement.
What can slag be used for?
waste slag from blast furnaces is used for road surfacing.
What is the products of blast furnace?
The main products of a blast furnace are pig iron (used to make steel) and slag (a byproduct that is used in construction materials).
What kind of fire bricks are used for molten blast furnace slag?
High alumina fire bricks are commonly used in applications involving molten blast furnace slag due to their high refractoriness and resistance to thermal shock. These bricks are able to withstand the high temperatures and harsh conditions of the slag without deforming or deteriorating quickly.
Why limestone is used in the blast furnace?
Limestone is used in the blast furnace as a flux material to help remove impurities such as silica, which would otherwise form a slag that interferes with the smelting process. When limestone is added, it combines with the impurities to form a molten slag that can be easily separated from the molten iron.
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 ?
Why is blast furnace waste gas mainly nitrogen?
Blast furnace waste gas is mainly nitrogen because nitrogen makes up about 78% of the atmosphere and is used as the primary gas for the blast furnace process. During the process, the injected air reacts with the fuel and iron ore to form nitrogen-rich waste gas.
What is Blast Furnace?
A blast furnace is used to extract iron from its ore.
What are argillaceous materials?
those which supply silica,alumina and iron oxide.EG: clay,blast furnace slag ashes,shale and cement rock.commonly used are clay and shale.
What is used in the furnace to extract the iron?
blast furnace
Which three substances are put into the blast furnace?
In a blast furnace, iron ore (Fe2O3), coke (carbon), and limestone (CaCO3) are commonly used. Iron ore is the source of iron, coke acts as a fuel and reduces the iron ore to iron, and limestone helps remove impurities by forming a slag.
What element is the blast furnace used to extract?
Iron (Fe)
