re Impact of ALKALY, SULPHURE and CHLORINE in Kiln operation and clinker quality ?

Sir

We are using feldspar in our kilnfeed due to which our hotmeal and clinker both shows high content of potassium. Can you just list some of the reasons why potassium chloride being highly volatile still comes along with clinker rather than exiting from bypass. 

Also how potassium chloride effects clinker quality.

Dear Ted

Can I request you to please elaborate why lack of oxygen at kiln back end(kiln inlet)  impacted the sulhure cycle in side the kiln and bottom cyclone. 

Thanks

Can I request you to please elaborate why lack of oxygen at kiln back end(kiln inlet)  or reducing condition impacted the sulhure cycle in side the kiln and bottom cyclone.  Any reaction with oxygen please share

Dear Sir,

Generally in oxidising atmosphere most of the suplhur will be convert to alkali sulphates which will leave the kiln in the form of alkali sulpahte in clinker

S + O2 + Alkali............> Alkali Suplahtes

Whereas during reducing conditions above mentioned reaction will be minimized and sulphur cylcle is likey to be increased , in resulting frequent buildup 

Under reducing conditions some addiotnal chemical reactions are considered as

CaSO4+ C(s)..........> CaO+SO2+CO

CaSO4+CO.........>CaO+SO2+CO2

since in above reactions SO2 is realesed tend to increase sulphur cycle in the kiln system.
