Thickness of insulation material

  1. Dec 3, 2007 #1
    hello!!!

    how do we calculate the thickness of insulation (wool) material to be used for a boiler.

    thanks

    I assume you mean something like ceramic fiber when you say "wool". Generally, the thickness calculation is just the heat conduction equation, but that's a small part of the story; the challenge is the design. What is the boiler temperature? What does the surface look like? Do you have convection outside? What temperature do you need to get down to? What is the ambient? How much room is there for insulation? What codes must you meet? How do you have to protect the surface?
