Stack

The temp is a bit high and unusual for a cement plant...they should have post kiln cooling.
The stack hieght is also not very high.
We use steel stacks - with a corrosion allownace.
U need to check out the gas composition and the acid dew points.
Then U take it from there.
I have heard of stackes that are refractory brick lined steel stacks.
Another method is to thermally lag the stack to prevent acid dew point from occuring - but the risk is start up/cool down times.
U really need the help of the process/chemical department and then analysis it from there.
There are also special paints out in the market - USA - baked/cured enamels.
Thanks

Stack design for a cement kiln
I would like to know how to design and fabricate stacks now a days.
Right now i am working on something with the following characteristics: A stack for a cement kiln that produces 2100 ton/day with a temperature design of 300 ºC and a working temperature of 190 ºC. The necesary height of this stack is 65 mts.
I want to know what kind of materials i have to use, i mean, do i have to build it all with concrete? , do i have to use steel? or, can i use a mixture of concrete and then steel?
Wich is the latest technology on this matter?, do i have to use any kind of internal refractory coat, such as special concrete?
Thank you all for any help you can give me, i am looking forward to receiving any answer from you.
