Combustion flue gas monitoring

Process flue gas monitoring for combustion optimization

Combustion in boilers, gas turbines, waste to energy, paper-mills, minerals, etc. | MIR 9000e

Customer: Any industry having a stake in improved combustion technologies

Material measured: Combustion flue gases

Installation: At the boiler outlet

Function: Reliable and accurate monitoring of O2 and CO for combustion control optimization

APPLICATION

Combustion has a number of outputs such as the ash and the emission to the atmosphere of flue gas. Before the flue gas cleaning system, if installed, the flue gases may contain particulate matter, heavy metals, dioxins, furans, sulfur dioxide, and hydrochloric acid. If plants have inadequate flue gas cleaning, these outputs may add a significant pollution component to stack emissions.

Gas monitoring at the boiler outlet

Combustion optimization is not only a question of power. Monitoring the flue gases on a boiler or burner, makes sense ecologically as well as economically. Poor combustion can produce corrosive compounds and ash deposits in the boiler itself. To avoid damage due to these by-products, combustion must be accurately evaluated by monitoring mainly the O2 and the CO.

SOLUTION

Eco-designed, ultra-compact, smart & connected instrument, the NDIR-GFC multi-gas analyzer MIR 9000e is a must have for measuring combustion exhaust gases from boiler, industrial furnaces and process applications, as well as for CEMS applications.
The MIR 9000e can measure simultaneously and continuously up to 8 parameters, depending on your selection: NO, SO2, CO, CO2, CH4, N2O, O2 and residual H2O) including greenhouse gases.
The gas monitor utilizes the most recent optical and electronic technologies offering increased precision and robustness, while requiring only limited maintenance and ultra low power consumption. Thanks to its breakthrough mechanical design for weight and power saving as well as its exclusive “inside the box” modular concept, the monitor is insensitive to T° variations in the range +5° to +40°C (no air conditioning required).

Smart and connected, with one click access to key functions via touchscreen or via full remote access to full operation from computer through TCP/IP connexion or on smartphone, through ENVEA Connect™ App (free download) and proprietary WiFi. Smartphone alerts and notifications, software updates, direct access to real-time and stored data with time frame selection to generate graphs, embedded Communication Protocol for DAHS software (WEX®) with automatic recognition and configuration, IoT services, etc. are just some of the ultra-innovative features that have been implemented in this highly innovative system.

Other compatible solutions from ENVEA are the MIR 9000H, the MIR IS or the in-situ monitor LAS 300-XD based on the TDL technology are used for online monitoring of gas parameters and able to measure in real time and simultaneously these 2 species and more, such as HCl, NH3 etc. if they are required by the process.
