TR-9300N ammonia escape analysis equipment

Introduction

The TR-9300N ammonia escape online monitoring system uses high temperature heat extraction technology to continuously monitor the escape ammonia in the denitration process. The system consists of sampling and transmission unit, pretreatment and control unit, and analysis unit. Industrial emissions monitoring and process control, such as: coal-fired power plants, aluminum plants, steel plants, smelters, garbage power stations, cement plants and chemical plants, glass plants, etc.

The analyzer uses the principle of Tunable Diode Laser Absorption Spectroscopy (TDLAS) to measure the concentration of specific gases in the process gas composition, including NH3, H2S, HCL, HF, etc. The system has the characteristics of high sensitivity, fast response, no interference from background gas, non-contact optical measurement, etc. It provides a reliable guarantee for real-time and accurate reflection of the change of escape ammonia.
