Why Preheater cyclone jamming happen due to chemistry point of view by Dr. K. Mohan Sir

Part-6: Why Preheater cyclone jamming happen due to chemistry point of view by Dr. K. Mohan Sir.
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

Thank you so much jk sir & K mohan Sir for sharing wonderful logical remedial for avoiding cyclone jamming ....

[@bhaveshtank311]

Useful information

[@safetysolutions7544]

Perfect. Thanks JK

[@MuhammadIlyas-tq8ch]

Please make a video on dip tube function, wear & tear and its installation procedure.

[@gosula.amaralingeswararao8698]

Good information sir

[@anandpathak3315]

Very nice sir

[@syedsohailrazakazmi2232]

Please recommend kiln operation and chemistry book

[@dpvishwakarma9567]

Please suggest to minimise CO in Preheater for cement kiln industry . We are using 10-15% AFR as well , our kiln has capacity of 7800 tph

[@GRAVITYINTERNATIONAL-hx6pt]

Is it possible to identify jamming of Cyclone Preheater by Level Measurement Switch ??

[@arvindgolhani1650]

Thank you so much sir

Do Dr mohan had any Chanel or website?

[@syedsohailrazakazmi2232]

Thanks a lot from Pakistan. Kiln zones and refractory selection video please. If already made please share link

[@charitymusonda9092]

Thank you for the wonderful explaination but please use English

[@DilipsinghRajput-gs7vt]

Sir me v pH pr duty krta hu

[@sshahnaz3682]

If VM of coal is high and coal ash is low I.e 10 will preheater cyclone cogging will take place .please discuss this topic

[@M.Elkhodary]

Plz in English language

[@cementpdm]

Sure, i will try.

[@SANDIPKUMAR-oo6xq]

sir no in Hindi

[@prashantpandey2838]

Sir please speech Hindi language

[@pollisettysaivenkatprasad1194]
