Stirred Reactor Heat Losses
Stirred Reactor Heat Losses
(OP)
Hi guys,
Anybody has a way to estimate the heat loss of an insulated stirred reactor, or what is the same, the estimation of insulation thickness. (In this case is a batch process and I want to figure the need of heating coils out)
I have found an useful freeware program "3E Plus 3.2", and I have estimated the heat losses but without agitation, and I need to include the agitation factor, to see the change in the heat lost.
Thanks.

Agitation should not affect the heat loss of a reactor. The overall heat transfer coefficient should be controlled by natural convection on the outside. That is why the metal temperature is very close to the actual liquid temperature inside in most cases.
My opinion only.

There is a great number of textbooks on heat flow through layers of different thermal conductivity, one of them is available as download version and mentioned here on engineering forum. With little effort you will do your calculations yourself.
