Heat exchanger
(OP)
Dear people
we have a tube in tube heat exchanger, it is blocked with solids. we have a slurry 10% solids going through one side and the other side is also 10% solids.
the solids size is around 100 mesh. these heat exchangers are blocked really bad.
if some one is involves in such kind of work before, please post your comments.
thank you every one for reading this

RE: Heat exchanger
What kinds of slurries are involved?
On a lighter note, you might have inadvertently stumbled across a rather effective filter design.

RE: Heat exchanger
the word tube in tube is a double pipe heat exchanger its just a common term we use when we talk to the maintainance people. anyway we have wood flour like powdered wood about 100 mesh,
we are pumping this one into a high pressure reactor, this heat exchanger is a recovery heat exchanger, accidentally we ha a power cut and the exchanger is blocked.
thats the application and cause of the block,
Thanks

RE: Heat exchanger
Sometimes electrically powered pumps in critical uses are spared with steam-turbine moved units.

a) Rod Cleaning
b) Hydroblasting
c) Chemical Cleaning
A variety of cleaning procedures are available.
During initial phase of my career, I was in a operating plant. I did remember that after power cut, the slurry handling lines & equipments will be purged/flushed with suitable media. This is a good eng practice.
