Borosilicate Foam Glass Lining Brick (Chimney)

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.

Product Description

亿人平台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.

亿人平台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 significantly exceeds 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.

Comparison of the Flue Gas before and after Desulfurization

Before DesulfurizationAfter Desulfurization
Hot and Dry Acidic Flue GasLow Temperature High Acidic Gas and Condesate
Operating temperature is generally between 130℃--150℃General operating temperature is between 40℃ to 50 ℃(Not det GGH flue gas heating system)
Moisture content is low, flue gas condensation, strong corrosiveHigh water content, the whole fule gas condesation, very corrosive
