Does the chimney have high acid resistance?
The acid resistant bricks used for chimney are usually made of custom-made trapezoidal acid proof bricks, and the physical and chemical indexes of acid resistant bricks need to be confirmed according to the chimney's actual emission. At this point, you can consult our kerei refractories.
The chimney particles and gases, mostly coal tar products, material acidic, therefore, take good acid resistance, acid proof brick, Grouts also used potassium silicate clay acid is preferred. If it is an ordinary high alumina brick, it does not meet the requirements of acid resistance, and only the chimney lined with acid resistant bricks.
