Lightweight acid-resistant castable for power plant chimney

The chimney lining of the power plant is poured with acid-proof castables ( acid-resistant castables ), which plays the role of heat preservation, heat insulation, acid resistance and corrosion resistance. In addition, linings for power plant chimneys also require refractory materials such as acid-resistant bricks, etc.

The application of acid-resistant castables in the power industry, and the role of the acid-proof castables.

Why use acid-resistant castables for pouring the lining of power plant chimneys, the mechanism of corrosion of power plant chimney lining.

The flue gas emitted from the coal-fired power plant is saturated with water after wet deacidification, and the flue gas temperature drops to 50 ° C -70 ° C, containing a small amount of corrosive medium such as sulfuric acid and entrained chloride.
Low concentrations of sulfuric acid and chloride are highly corrosive and have a stronger corrosive and destructive effect on the inner wall of concrete than high-concentration sulfuric acid. Therefore, the anti-corrosion performance of the chimney lining after the wet desulfurization of flue gas from coal-fired power plants is put forward.

The advantages of Rongsheng acid-resistant castables, the good points of using acid-resistant castables to pour the chimney of a power plant.

The acid-resistant castable for the power plant chimney produced by Rongsheng Kiln Refractory Company and the anti-seepage water-tight acid-proof insulating castable can be directly poured into the inner layer of the chimney. After acid-resistant castable casting, these castables have the advantages of high compressive strength, replacing the original traditional lightweight bricks and light acid-resistant bricks, and are convenient for construction.
