Snow man formation in clinker cooler

Posted in: , on 3. Apr. 2008 - 10:26

Dear sir,

In our plant we are facing frequent snowman formation problem (formation of heeped coatings near cooler inlet and kiln hood).We are using 6 blasters of 5 kg/cm2 pressure which are operating normally. May I know what are the reasons for the formation of this type of coatings(snowman)? Does any of the raw material properties effects the coating formation

Regards,

Hi Yogesh,

Good question. Problem solving is like detective work. You have to get the clues, then propose a theory, then go back and look for more clues to either back up or reject the theory.

Some questions to ask

1 - What is the chemical analysis of the snowman formation? There are many products of combustion in a kiln.

2 - Do any of the raw materials affect it? Good question. How can you verify it?

3 - Are you introducing flux? Where and how?

4 - Is there a temperature gradient at the Cooler entry? Does this have any significant effect.

5 - Look at the variables, and what are the consequences of

-- High flow, Low flow

-- High temperature, Low temperature

-- High flux, Low flux

Best of luck - John.rz
