GBLA-500 Ammonia Escape Integrated Online Monitoring System

Product Introduction

GBLA-500 Ammonia Escape Integrated Online Monitoring System (NH)₃、NO、O₂）Based on the principles of tunable semiconductor laser absorption spectroscopy (TDLAS) and ultraviolet differential absorption spectroscopy (DOAS) technology. The system consists of three main parts: preprocessing, gas analysis module, and data processing and display. The tested gas undergoes high-temperature sampling probe dust removal, high-temperature transmission through heat tracing pipes, and enters the high-temperature gas analysis module (TDLAS+DO-AS technology) for analysis and measurement. Effectively solved the blockage of the flow path caused by low-temperature crystallization of ammonium salts, resulting in the precipitation and dissolution of NH in condensed water₃The resulting measurement accuracy is low, and the high dust attenuation optical path of the in-situ system leads to technical difficulties such as inability to measure.

Product Features:

Single line spectroscopy absorption technology avoids background gas interference, has a low detection limit, and has a small range drift;

Heat tracing above 220 ℃ to avoid ammonium salt crystallization and water absorption;

Compact structure, easy to install, high degree of automation, and low maintenance;

Integrating multiple parameters into the same system while maintaining low measurement costs.

Product Application:

Suitable for ammonia escape emission monitoring and process control of SCR or SNCR denitrification devices, including coal-fired power plants, aluminum plants, steel plants, smelters, glass plants, waste to energy plants, cement plants, chemical plants, etc.
