Why can’t oxygen-enriched hot air stoves in blast furnaces supply air and provide heating at the same time?
Thread Content
I would like to ask why it is not possible to simultaneously supply air and provide heating in a blast furnace with oxygen-enriched hot air stoves? Or heat first, then supply air, and stop heating while the air is being supplied?
A hot blast stove should be a type of energy-storing heat exchanger. The principle is to first use the gas produced by blast furnaces, burned to generate heat, to heat the “ceramic balls” in the furnace. When a certain temperature is reached, the heat-conducting air plus oxygen enters the blast furnace to heat the charge, and this process repeats itself in a cycle. If heating and air intake occur simultaneously, such high temperatures would not be generated. It is recommended to understand it based on the overall principles of blast furnaces. For reference.
Thank you, it’s a regenerative heater after all
He was referring to regenerative burners; the furnace has nothing to do with the burners. Don’t confuse the concepts
Does that mean burners are used to heat the air?
