Continuous Emission Monitoring Systems

Designed to meet the requirements of 40 CFR 60 & 75, QAL1 and QAL 3 of EN14181 & EN15267-3, the MIR-IS offers maximum data availability, low maintenance and compliance with acceptable regulations.

Fast and simultaneous measurement of up to 10 gases from a choice of HCl, NO, NO2 (NOx), SO2, CO, CO2, THC, CH4, HF, N2O, O2 , H2O etc. at or near the sampling location Robust and reliable short extractive analyzer with built-in exclusive permeation sample drying system for the measurement of wet and corrosive samples Fast response time, with automatic cross interference correction Reproducible and highly accurate; excellent calibration stability with automatic optical check Ease of installation: single stack entry, on-stack or close-coupled, therefore re-ducing costs Heated probe in different materials and lengths to suit the application External signal input for up to 5 additional measurements (flow rate, pressure, gas temperature...) or any other analog input Built in a stainless steel tight box enclosure for safe outdoor installations Intrinsic security with on-board residual H2O measurement On-board paramagnetic cell for long term O2 measurement Powerful remote control and display functions Graphic LCD screen with real time synoptic

MAIN APPLICATIONS:• Industrial Power Boilers and Furnaces, Chemical and Petrochemical Plants• Incineration, Co-Generation, Gas Turbines• Process Control, Pre/post Scrubber Measurements• Coal/Oil/Gas Fired Combustion Monitoring

MIR IS Close-coupled Multi-Gas IR GFC AnalyzerMEASuREMENT TECHNIQuE:

Developed specifically for CEMS and process online monitoring, the MIR-IS multi-gas CEM analyzer is a compact close-coupled system based on our well-known MIR 9000 analyzer. Providing high performance, sensitivity and accurate measurements on a large number of gas parameters, the MIR-IS offers very fast response time (less than 40 milliseconds). It uses the Infra-Red Gas Filter Correlation principle, a well-established method to reduce cross interferences between compounds, and therefore providing measurements with a high accuracy and repeatability.

The MIR-IS uses a 16-position rotating correlation wheel with on-board interferential gas filters, allowing multiple simultaneous gas measurements. The optical bench includes a low volume gas cell with a 12 m optical path length and incorporates aspheric and aberration correcting mirrors. A built-in paramagnetic sensor can be added for O2 measurement and correction, and the analzyer accepts and displays additional external inputs (flow, temperature, pressure, etc.). The powerful embedded software integrates and compiles infrared detector signals and calculates concentration of all compounds simultaneously. All measurements are available in graphical and tabular formats, but also on digital (RS232/485 & TCP IP) and analog outputs (mA or V configurable). A large LCD screen with keypad powered by user-friendly and easy to configure software with diagnostic functions allows easy user access. uSB interface allows easy and fast software upgrades and data extraction possibilities.

MIR-IS is the unique in the CEMS market offering an accurate multi gas analysis solution (up to 10 gases including HCl and HF + O2 as an option) integrating optional flue gas temperature, flow and pressure measurements on a single display.
