Insulation Material for Combustion Furnace
Insulation Material for Combustion Furnace
(OP)
Dear Engineers,
Good day to you. I am designing the ducting system for the combustion furnace. A supplementary burner is used and the highest adiabatic flame temperature is around 650-675 degC. And I have surveyed two products, which are superwool blanket (1200 degC) and pyro-bloc (1260 degC). Besides the classification temperature, what are the other parameters I have to look at in order to select the insulation material?
And is superwool blanket or ceramic fibre (isowool) acceptable for combustion furnace insulation?
Thanks.

If the thing being lined is expected to need frequent access for maintenance, a so-called "body soluble" ceramic fibre should be selected.

Thanks for you reply. I have applied a layer stainless steel lining to cover the superwool/isowool blanket, thus I guess it is one of the ways to ensure that the insulation layers are intact. Hopefully this is acceptable.
If superwool/isowool can be used for combustion furnace, then when will we use pyro-bloc for insulation purpose?
RE: Insulation Material for Combustion Furnace
Board materials are used where more mechanical robustness is required.
I can't comment on the wisdom, necessity or cost implications of putting an inner stainless steel lining on the insulating material without understanding the application in detail.
