Industrial Boilers

ZTW Ceramic Integrated Technology has become the gold standard for controlling flue gas emissions from coal, biomass, and liquid fuel boilers. It is a proven solution that can economically, efficiently, and significantly reduce pollutant emissions in flue gas over the long term
Removing pollutants includes nitrogen oxides (NOx), sulfides (SOx), particulate matter, and mercury HCl、HF。

The ceramic integrated desulfurization, denitrification, and dust removal technology applied in industrial boilers is an efficient flue gas purification solution that integrates dust removal, desulfurization, and denitrification functions. This technology uses ceramic fiber filter tubes as the core carrier and achieves synergistic treatment of multiple pollutants through catalysis and filtration, especially suitable for high-temperature and highly corrosive flue gas environments.

1. 1. Functional integration of ceramic filter tubes​
       (1). Substrate characteristics: The ceramic filter tube is made of porous ceramic fibers as the substrate, with a porosity of>85% and a pore size of 25-45nm. It has high mechanical strength, high temperature resistance (350-900 ℃), and chemical corrosion resistance (such as SO ₂ and alkali metals).
       (2). Multi functional coating: The surface of the filter tube is loaded with a catalyst (vanadium titanium series), which synchronously catalyzes denitrification (NOx → N ₂) and desulfurization (SO ₂ → sulfate) within a temperature window of 180-450 ℃, while intercepting particulate matter.
   2. Collaborative governance mechanism​
       (1). Dust removal: The outer wall of the filter tube intercepts more than 99% of the dust, and the emission concentration remains stable at ≤ 5mg/m ³
       (2). Desulfurization: Injecting desulfurizer (such as lime powder) to react with SO ₂, desulfurization efficiency>99%
       (3). Denitrification: Injecting a reducing agent (such as 20% concentration ammonia water) to reduce NH3 and NOx to N ₂ under the action of a catalyst, with a denitrification efficiency of ≥ 95%
