CEMS for Solid Waste Incineration

Product Description

Domestic waste incineration plants are required to conduct automatic, continuous and online monitoring of the main components of incineration flue gas. The basic monitoring items include HCl, SO₂, NOₓ and soot, while CO and HF also need to be detected in some occasions. The Model TK-1000 Continuous Emission Monitoring System (CEMS) for solid waste/domestic waste incineration flue gas adopts technologies such as DOAS UV differential absorption spectroscopy and tunable diode laser absorption spectroscopy (TDLAS). It is capable of measuring multiple parameters including SO₂, NOₓ, O₂ and HCl. With a simple structure, modular design, high stability and low operating costs, the system is installed in the monitoring station room for easy operation and maintenance.

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.
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.
The reliable long optical path heated gas cell design allows the optical path to reach up to 760 mm.
It supports ultra-low concentration measurement with a resolution of up to 0.1 ppm.
The spectral width of the semiconductor laser is less than 0.001 nm, which avoids cross-interference caused by dust and moisture.
