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.

What is the Heat loss in blast furnace?
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.
Why furnace pressure of boilers kept negative?
High furnace pressure is a direct indication of a disturbance in combustion performance. The rate of change in the furnace pressure can vary very much, that is from a simple sudden surge due to fuel variations to a huge furnace explosion
What is A furnace with a vertical air flow and the blower compartment located on the top of the unit called?
It is called an upflow furnace. This type of furnace takes in air at the bottom, heats it, and then releases it through the top vents.
What is reflection as is seen in blast pressure?
Reflection in blast pressure refers to the phenomenon where blast waves bounce off surfaces such as walls, ceilings, or the ground and return to the source of the explosion. This can increase the pressure and intensity of the blast wave in enclosed spaces, leading to more widespread damage and injuries. Understanding how blast waves reflect off surfaces is crucial in designing structures and protective measures to minimize the impact of explosions.
Why negative pressure maintained in furnace?
Negative pressure is maintained in a furnace to ensure that combustion gases and fumes are properly contained within the system and vented outside. This prevents the escape of harmful gases back into the living area and also helps improve the efficiency of the furnace by promoting the smooth flow of air and fuel.
What is the function of septum valves in blast furnace?
Septum Valves are installed after the dust collector venturi scrubber , to decrease the pressure of Top gas from the blast furnace to supply it to other processes at low pressure.
How does limestone coke and iron ore get into the blast furnace?
