Why Chlorine Bypass System in Preheater (Kiln Inlet) | Cause of Cyclone Jamming

Chlorine Bypass System at Kiln inlet | Cause of Cyclone Jamming of Preheater of Cement plant
Causes of Cyclone Jamming are:
1. Incomplete consumption of coal
2. Kiln inlet & upper part of preheater temperature is higher
3. Mismatching of Kiln inlet & Precalciner outlet temperature
4. Increase recirculation of Fine partical at bottom stage cyclone
5. Internal circulation of Volatile ie So₃, Cl, Alkalis in cyclone
6. Insufficient of suction in cyclone due to low RPM of PH Fan
Cyclone causes due to chemistry point of view
What is the reaction affinity in The volatile?
Cl + Alkalis K₂O, Na₂O = KCL , Nacl
2Cl Residual Clorine + Ca = Cacl₂
Alkalis K₂O, Na₂O + S0₃ = K₂So₄, Na₂So₄
Residual Alkalis K₂O, Na₂O + C0₂ = K₂Co₃, Na₂Co₃
Excess S0₃ + Cao = CaSo₄
What are the factor for recirculating behavior of volatile?
1. Melting point of Volatiles
2. Temperature dependence vapor pressure of Volatiles
NaCl Melting point is 801 ˚C, KCl Melting point is 776 ˚C, Na₂So₄ Melting point is 884 ˚C, K₂So₄ Melting point is 1074 ˚C, CaSo₄ Melting point is 1450 ˚C, K₂Co₃ Melting point is 897 ˚C, Na₂Co₃ Melting point is 854 ˚C
What are the remedial measure to avoid cyclone jamming?
1. Maintain So₃ level in Hot meal 6%, Maintain Chloride level in Hot meal 3.5%
2. Both on loss free basic, means ignited basis
3. Monitor & Balance Alkalis Sulphur Ratio between 0.8 to 1.2

Thanks a lot for that valuable information , but hope to make the same session in English please

[@multanmultan5717]

Nice sar

[@gosula.amaralingeswararao8698]

Good information sir

[@TheRULAReRA]

Nice explanation..
Sir one separate vedio for functioning of CBS in details.

[@mohammedwasifpatel4239]

Thanks for explaining
1 question. What about collected chlorine dust in bag house? Is it used further in process or discarded

[@aditisharma6549]

Nice video, can you please make video on white cement and it's process

[@khalilbenjebara5409]

Thank you for the valuable content, but try to use English in order to make it clear to everyone !

[@user-yzmz]

We need this video in English

[@ahmedmohamed-mc3fv]

Plz as we know chlorine siblimation happens at 700°C nearly at cyclone 3&4.My question is why bypass system intake is at kiln inlet while chlorine sublimates at cyclone 3&4??.How could it captured at kiln inlet ??

[@cementpdm]

By chlorine bypass system.. Photo in video end..slide

[@ahmedmohamed-mc3fv]

@@cementpdm yes I know. My question why bypass system installed at kiln inlet not in cyclone 3 or 4 where chlorine sublimates?

[@saritaathani8298]

Thanku sir

Could you explain this video in English plz, or add English subtitle
