Quick Details
Specifications
1., 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 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.

Hot and Dry Acidic Flue Gas |
Low 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 corrosive |
High water content, the whole fule gas condesation, very corrosive |
