Ammonia (NH3) Analyzer Measuring Principle

The ESE-LASER Series Online Ammonia (NH₃) Analyzer uses Tunable Diode Laser Absorption Spectroscopy (TDLAS) to measure ammonia concentrations in industrial process gases and flue gas. TDLAS measures ammonia by detecting its selective absorption of laser light at specific wavelengths. The analyzer measures changes in laser intensity and calculates the NH₃ concentration using spectral absorption analysis. This technology enables selective, accurate, and rapid ammonia measurement, with configurable measurement ranges extending from percentage concentrations down to ppb levels.

Key Features

  • High Selectivity: Uses TDLAS technology to target specific NH₃ absorption lines, minimizing interference from other gases and enabling selective ammonia measurement.
  • Wide Measurement Range: Supports NH₃ measurement from ppb levels to percentage concentrations, depending on the configured measurement range and application.
  • Fast Response Time: Provides rapid, real-time monitoring of ammonia concentrations, allowing operators to detect concentration changes and respond promptly.
  • Non-Contact Optical Measurement: Uses a laser beam passing through a gas cell or process duct to measure NH₃ without direct contact between the optical sensing components and the gas stream.
  • High Accuracy and Precision: Combines narrow-linewidth laser technology with spectral analysis algorithms to deliver accurate and repeatable NH₃ measurements.
  • Low Maintenance and Long-Term Stability: Features a laser-based optical measurement design with minimal moving parts, reducing maintenance requirements and supporting stable, continuous operation.
  • Compact and Modular Design: Offers flexible installation options for integration into existing monitoring systems or standalone industrial applications.
  • Continuous Ammonia Slip Monitoring: Continuously measures residual NH₃ in SCR and SNCR denitrification systems, supporting ammonia injection control and NOₓ emission reduction.
  • Wide Industrial Applications: Suitable for ammonia monitoring in metallurgy, coking, power generation, cement production, and biomass-fired combustion processes.
