Hey;
Our kiln capacity is 5000 tpd with 5 stages preheater and bypass system, last week the dip tube of cyclone 5 (last cyclone before hot meals enter the kiln) damaged completely, we don't have spare parts to replace the dip tube so we have decided to run the kiln without dip tube. My question is; how will kiln operation be affect when run it without dip tube?
Best Regards
Nael
Dear,
It is really difficult to find out the significant effect after removal of Dip tube,Cyclone outlet temperature can b increase little 5-10 degree, dust losses will increase slightly and increase in fuel consumption.
Hey Nael,
Dip tube length and diameter are naturally one of the most important factors for the cyclone design and I think you will face several operation problems if you run the kiln without cyclone-5 dip/ immersion tube, some of them are:
1- Poor separation efficiency of cyclone-5.
2- Too high dust circulation.
3- Higher pressure drops in the cyclone.
4- More gas consumption.
5- Instability of burning process.
Best Regards
