The gas is heated to 800–900 degrees
Thread Content
I would like to ask about the use of gas for the direct reduction of iron – when the gas is heated to 800–900 degrees, what type of heating equipment should be used? Are there any suitable manufacturers you can recommend? Thank you
This process can be designed independently; a fluidized bed is used to heat the mineral powder to 900 degrees Celsius by burning some gas, and then gas is used for reduction.
I wonder what the gas pressure is like? Heating to 900 degrees presents limitations in terms of available materials, and the components of the gas may coking.
Couldn’t we just burn part of the gas with limited oxygen?
Do you use a furnace to heat gas or coke? Are you still planning to use coal-derived syngas as the reducing agent?
The temperature is not low; you can consult manufacturers of hot air furnaces or other heating furnaces to see if they can meet the requirements Another option is to use the heat generated by burning syngas to heat itself, in which case the resulting gas will contain a higher amount of carbon dioxide.
