- Model FGA Series - Compact Multigas Continuous Emissions Monitoring Systems (CEMS)

From

0

A compact, reliable multi-gas analyser for measuring flue gas emissions in processes burning natural gas and biomass. The FGA provides accurate, reliable measurement of carbon monoxide, nitric oxide and oxygen in flue gases. It is an integrated solution for Continuous Emissions Monitoring Systems (CEMS) applications in smaller combustion processes.

Easy to install and operate, the FGA also calculates values for combustion efficiency, NOx and carbon dioxide. This information allows better process control, which lowers fuel costs and keeps emissions within compliance levels.

A pair of sensors is used to analyse each of the species in the sampled flue gas, alternating every 30 minutes. This extends sensor lifetime and ensures a stable baseline, essential for low-level measurements, delivering high sensitivity and low drift.

The FGA can be used in any combustion process where the sulphur dioxide concentration is less than 50ppm, making it a vital solution for the Minerals, Power Generation, and Steel industries.

Easy to Install and Service
Fully weatherproof to IP65 standards, the FGA can be heated or cooled for extreme environments, allowing placement close to the measurement point. It is engineered for easy use, with low maintenance needs. Automatic calibration allows for unattended operation.

Meets International Approvals
The FGA has MCERTS QAL1 approval to BS EN 15267 for emissions measurements in Europe. It also meets the requirements of US EPA Performance Specifications 2, 3 and 4 for the relevant gases. This ensure international regulatory compliance measurements.

All-In-One Design
An alternative to traditional, multiple-analyser CEMS, the FGA integrates sample conditioning, gas analysis calibration and data processing into a single system. This provides a robust, reliable and simple emissions measurement for regulatory compliance in smaller combustion processes.
