The Problem & Solution - Desulfurization And Denitrification

Core Challenges

In flue gas desulfurization (FGD) and denitrification systems, inefficient atomization leads to poor gas-liquid contact, reducing pollutant removal efficiency.

Nozzles are frequently exposed to corrosive chemicals, high temperatures, and particulate-laden gas streams, resulting in clogging, erosion, and shortened service life.

Our Solution

Our nozzles are engineered for optimal atomization, ensuring uniform droplet distribution and maximum contact between flue gas and scrubbing liquid for higher SO₂ and NOx removal efficiency.

Built with corrosion-resistant and wear-resistant materials, our solutions ensure long service life, reduced maintenance frequency, and stable operation under harsh environmental conditions.
