SHEFFIELD, UK, 5th NOVEMBER 2019 – CELSA GroupTM, one of the largest manufacturers of steel long products in Europe, has implemented AMETEK Land’s FGA 930 flue gas analyser to monitor carbon monoxide (CO) emissions and meet required legislation.
CELSA GroupTM operates in 11 countries, running steel mills, rolling mills, transformation plants, distribution companies, service centres and recycling companies. At its Castellbisbal plant in Barcelona, Spain, the company produces small section profiles as well as square flat and angular rods for industries such as construction, automotive, energy and equipment goods. The plant experienced abnormal CO readings from its billet reheating furnace exit and in order to meet emission legislation and to better monitor its CO levels, CELSA Group™ needed to replace its portable analyser system with a fixed one.
After a thorough review, the company chose AMETEK Land’s FGA 930 flue gas analyser, which is part of the FGA 900 range of 3-in-1 multi-gas analysers.
These compact, innovative analysers accurately and reliably measure flue gas for Continuous Emissions Monitoring System (CEMS) applications on processes that burn natural gas and biomass. To ensure accurate measurement, CELSA Group™ installed the FGA 930 close to the stack and the probe high inside, at a height of 1.5 and 5 metres, respectively.
By installing the analyser, CELSA Group™ can now continuously monitor its CO emissions, detect unburnt gas and prevent burner failure all while improving the overall efficiency of its furnace combustion.
Easy to operate, the FGA range allows for better process control, which lowers fuel costs and ensures emissions can be kept within compliance levels.
AMETEK Land’s innovative design uses a pair of sensors to analyse each of the species in the sampled flue gas, alternating every 30 minutes. This extends the sensor’s lifetime and ensures a stable baseline, which are essential for low-level measurements, delivering high sensitivity and low drift.
The FGA is applicable to any combustion process where the sulphur dioxide concentration is less than 50 parts per million, making it a vital solution for the mineral, steel, and power generation industries.
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 emissions measurement for regulatory compliance in smaller combustion processes.
Featuring fully weatherproof enclosures sealed to IP65 standards and optional heating or cooling for extreme environments, AMETEK Land’s range of FGAs are TUV and MCERTS EN14181 QAL1 approved for emissions measurements in Europe. It also meets the requirements of US EPA Performance Specifications 2, 3 and 4 for the relevant gases. The range of FGAs is engineered for easy use and low maintenance needs. The analyser’s automatic calibration allows for unattended operation.
Juan Jiménez Solís, Maintenance Manager at CELSA GroupTM, said: “We are very satisfied with the solution from AMETEK Land. It has given us peace of mind and reassurance that we are not exceeding CO and CO2 levels, in line with current legislation. It has also helped prevent burner failure, which has improved asset management and reduced costs.”
“Our FGA 900 analysers are in strong demand because of their accuracy, reliability, low drift, and long-term CEMS monitoring capabilities,” said Iñaki Araquistain, Sales Manager – Spain and Portugal at AMETEK Land. “CELSA GroupTM can be assured that by having the FGA 930 installed, they have an effective monitoring system that enables them to remain compliant.”
