I would appreciate it if the experienced colleagues could help me check whether such a boiling furnace design is reasonable
Thread Content
I would appreciate the guidance of those with more experience: Is the design of the following boiling furnace reasonable? Please point out any issues if there are any. Thank you! Equipment: Acid production from 100kt of sulfur concentrate; particle size of raw material: 0.09 mm. Design of the bubbling furnace: Mineral feeding rate: 300/d; burning intensity: 10.5; area of the bubbling layer: 28.56 m2; area of the expanded layer: 66.48 m2; effective volume of the furnace chamber: 665 m3; height of the bubbling layer: 1100–1400 mm; exit temperature: 920°C; air flow at the furnace bottom: 27770 m3/h; gas velocity in the bubbling layer: 1.15–1.44 m/s; residence time: 16–17 s.

The roasting area is relatively large, and the residence time is a bit long. Operating 150,000–180,000 tons is no problem.
The raw material you mentioned is sulfur concentrate; if it is a non-ferrous metal ore, this temperature is clearly too high.
It’s still reasonable; the sulfur concentrate is very fine, so it’s necessary to have a larger furnace.
There should be no problem. It involves burning sulfur concentrate; a larger furnace is better, as it provides some margin for flexibility and improves adaptability
