High Temperature Insulation Thermal Conductivity

Heat transfer engineering.

High temperature insulation thermal conductivity.

Fibre board and shape high temperature high performance insulation. Chimney and duct insulation in power generation plants. These insulation materials have a porosity 45. High temperature wools are characterized by low thermal conductivity low bulk density and low heat capacity.

High temperature wool can therefore be used to build very energy efficient periodically operated systems that can be heated and cooled quickly. High temperature insulation products are used in industrial applications to minimize the heat energy loss. Kaowool fibre boards and shapes feature low thermal conductivity excellent thermal shock resistance and low heat storage for effective energy savings. Mineral wool insulation thermal conductivity temperature and k values.

We dedicate a complete page on thermal conductivity later work is in progress. All high temperature insulation wools shrink at high temperatures. Ranges are marked with. Perlite insulation thermal conductivity of perlite insulation temperature and k values.

In particular for the construction of industrial furnaces dryers and apparatuses but also in the cement and petrochemicals industries it is the classical cost efficient insulating material. Nr 1000 calcium silicate board is white and hard high temperature thermal insulation material based on lightweight calcium silicate with high strength low thermal conductivity lightweight pressure resistant character it can be used at most different areas of industry as backup insulation. High temperature insulation wool is an ultra lightweight insulation material that due to its properties provides highly efficient thermal insulation for industrial furnace construction applications. Insulation material thermal conductivity chart.

Various insulation material thermal conductivity chart. Our high temperature insulating fibre blankets provide thermal insulation in processing of metals petrochemicals cement ceramics and glass and are used by manufacturers of equipment for aerospace automotive marine and domestic applications. High and fine porosity leads to low thermal conductivity. R values per inch given in si and imperial units typical values are approximations based on the average of available results.

These fibre boards and shapes are mechanically strong and dimensionally stable up to 1649 c 3000 f. Although some non oxide ceramic fibers such as sic and c etc show higher thermal stability and infrared extinction coefficient than oxide ceramic fibers their high thermal conductivity the thermal conductivity of sic is 490 w m 1 k 1 and c is 800 w m 1 k 1 restrict their usage as thermal insulation materials. For instance metals typically have high thermal conductivity and are very efficient at conducting heat while the opposite is true for insulating materials like styrofoam. In short traditional single phase ceramic fibers can t meet the requirements of high temperature insulation materials for high thermal stability and low thermal.
