Borosilicate Foam Glass Lining Brick
- Borosilicate foam glass, B203 containing, has good resistance to both acid and alkali, so it is a good protection layer to acid condensation produced from wet desulphurization.
- It works as a barrier to the alteration of high temperature and low temperature inside chimney, thus relief the chimney wall from thermal stress, and extend the service life of chimney.
- The compression strength of B203 containing foam glassbrick reaches more than 1.5MPa, which significantly exceeds the requirement of chimney liner, in a way offers potential to reduce the cost of the chimney.
- Its coefficient is less than 0.058 w/m.k， and its service life is the same as the chimney itself.
