Denitrification CEMS

Product Description

The Model TK-1000 Continuous Emission Monitoring System (CEMS) for denitration flue gas is capable of monitoring parameters in gas such as NOₓ, O₂, temperature, pressure, flow rate, humidity, and particulate matter. The measured gas is sampled via a sampling probe and heated sampling line, then enters the high-temperature gas analysis module (based on Differential Optical Absorption Spectroscopy (DOAS) technology) for analysis and measurement. The system equipment is installed in the monitoring station room, facilitating easy operation and maintenance. The entire system features a simple structure, modular design, high stability, and low operating costs.

Technical Advantages

All instruments of the complete system are self-developed, featuring a standardized and modular design for simple and reliable composition.
Based on UV differential absorption spectroscopy (DOAS) technology, the innovative multi-parameter joint estimation and interference cancellation algorithm achieves extremely low zero drift and span drift over a wide temperature range, with the minimum detection limit of NO as low as 0.05 mg/m³.
Adopting PLC control with a high level of automation, the liquid crystal screen displays the system flow path and collects detailed status information of the system, which can serve as the most favorable resource for data validity verification.
