Bulk density of refractory for stack on heater

Bulk density of refractory for stack on heater

Bulk density of refractory for stack on heater

I am trying to find a reference that will give me the bulk density of refractory used to line a stack on top of a convection box that rests on a heater (I believe). I am trying to determine the weight of the stack section with the insulting refractory for lifting by crane to replace the existing convection box.

The stack and box were originally manufactured in 1998. I did find a note calling that appears to read "1:2:4 LHV Refractory w/ 3% S.S. Needles". Text on old drawing copy is hard to read so not sure it makes sense or I can read it accurately.

I assume the density of refractory is a function of the material and temperature is has to insulate. I've seen references on a drawing calling out "ceramic fiber needle blanket 2300 deg Fahrenheit" but I am not sure that would be a representative temperature for what comes out of the stack.

Any suggestions on where to find bulk densities for refractory would be appreciated.

I think you need to find out exactly what refractory is there ; There is a very wide selection.

RE: Bulk density of refractory for stack on heater

Tried but what I'm told is it doesn't exist. I've pulled a cut sheet off internet from a specific manufacture meeting the 1-2-4 LVH criteria stating the bulk density is 64 pcf. I've had to move forward as it's a scheduled lift so I used 70 pcf. A will also increase my total weight by 50% to account for any misc. not identified and the refractory. There is always something missing. thanks for your comment.
