"Hi everyone,

In our plant the top cyclone temperature is around 375 C. The dust recurculating is around 13% of the feed. Because of the build-up in the fun we are facing with unplanned shutdown every week. I thought if we decrease the temperature somehow, we can decrease the build-up and also lower the dust recurculating rate. According to literature there is such a process applied. I couldn't find any feedback about the process.

Anybody using or know this system pls reply me..

Yours Sincerly"

I've openned a topic starting with this..

Thank you everyone.
