High-Temperature UV Flue Gas Analyzer

Product Overview

The High-Temperature UV Flue Gas Analyzer is designed for direct measurement of high-temperature flue gas, using Ultraviolet Differential Optical Absorption Spectroscopy (UV-DOAS) technology combined with hot-wet extraction sampling. Unlike traditional cold-dry methods, this analyzer requires no condensation equipment, preventing component losses such as SO₂ and ensuring higher measurement accuracy. The simplified gas path allows direct analysis of raw flue gas, significantly reducing failure rates and maintenance requirements. The instrument can simultaneously measure SO₂, NO, and NO₂ concentrations in flue gases from stationary sources, making it ideal for environmental monitoring and high-temperature flue gas detection.

Working Principle

The analyzer utilizes UV-DOAS technology to measure SO₂, NO, and NO₂ based on their specific ultraviolet light absorption characteristics. High-temperature flue gas is sampled directly via the hot-wet extraction method, avoiding condensation losses. The measurement cell features a long-path multi-pass design to lower detection limits and improve sensitivity. With a pulse xenon lamp as the light source and a mechanical-motion-free optical path, the instrument achieves high stability, excellent vibration resistance, and long-term reliability. NO and NO₂ concentrations can be measured directly without the need for an NOx converter.
