Alkali and Jamming

Dear All,

A coating sample, from the severely jammed smoke chamber , was analysed

and following prominent results obtained -

%Na2O = 0.52

%K2O = 3.52

%Cl = 0.05

%SO3 = 1.65

These results suggests high K2SO4 in sample? Am I write?

If it is true, then i want to ask another question, how it possible, because K2SO4

is always carried with clinker.

I also like to solicit your comments on the nature of his coating.The coating was

really very hard.

 

Kind Regards,

Gulam Dastgir

Hello Mr Gulam Dastgir

 

Choking in the smok chamber is due to the  Na and K  chlorides and  high temperature but K2SO4 remains with  the blocked material thats why   K2SO4 analysed in the coating

Re: Alkali and Jamming

Dear Azhar,

I am sorry, but i don't get what you to clarify?

What i know is that K2SO4 generally does not circulate up to smoke chamber as the

case is with alkali chlorides and Na2SO4.

Contrary to this, the K2SO4 in smoke chamber is abnormally on higher side.

This is what I am confused about.

 

Kind Regards,

Re: Alkali and Jamming

Im trying  say that blocking in the smoke chamber is due to the saturation of Chlorides and the Na-Sulfate, ones the chamber start to blocked , meal  accumulating in that area and that meal contain the Ka-sulfate so your are getting Ka-sulfate in the analysis , and more hardens of the blocked material is due to the high amount of heat
