1. 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.
2. 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.
3. the compression strength of B203 containing foam glass brick reaches more than 1.5MPa, which would exceed the requirement of chimney liner, in a way offers potential to reduce the cost of the chimney.
4. Its coefficient is less than 0.058 w / m.k, and its service life is the same as the chimney itself.
