CEMS Extractive Gas Monitor Case Study
Eagle Valley Clean Energy
12MW biomassfired (waste wood) electricity generating facility
The Challenge
Eagle Valley Clean Energy, LLC owns and operates a 12MW biomass power plant, generating electricity from combustion of waste wood.
The customer was using a cold dry extractive gas analyser for NOx compliance monitoring which was reported to be old and unreliable due to lack of maintenance which is a heavy requirement of this measurement technique. The customer was
looking to replace this system but had reservations on investing in another extractive gas analyser.
ESC / Monitoring Solutions offered the CODEL In-Situ GCEM40 Series but due to the installation being immediately after the the ESP, this caused vibration on the chimney stack resulting in a measurement which wasn’t ideal.
The Solution
CODEL offered a more suitable solution by means of upgrading the In-Situ GCEM40 to the GCEM40E, CODEL’s Hot Wet Extractive version in order to eliminate any vibration related issues.
The CODEL GCEM40E analyser was installed in August 2022 with a requirement to be in operation before the upcoming EPA test. In January 2023 we assisted plant operators to check the 40E analyser prior to the EPA source test.
During the test, CODEL 40E NOx was 5ppm lower on average compared to the reference method and the 40E NOx CEMS passed the test. Auditing company have not advised any actions on correcting the small discrepancy as it is within acceptable tolerance.
The Result
CODEL offered a more suitable solution by means of upgrading the In-Situ GCEM40 to the GCEM40E, CODEL’s Hot Wet Extractive version in order to eliminate any vibration related issues.
The CODEL GCEM40E analyser was installed in August 2022 with a requirement to be in operation before the upcoming EPA test. In January 2023 we assisted plant operators to check the 40E analyser prior to the EPA source test.
The CODEL 40E analyser is running flawlessly offering low maintenance, high reliability and very small span gas consumption in comparison to fully compliant CEMS.
GCEM40E CEMS Extractive Gas Monitor
The GCEM40E hot extractive multi-channel gas analyser is CODEL’s industry-proven continuous emissions monitor for difficult applications. Designed exclusively for use on a wide range of applications where the flue gas temperature is abnormally high, low or saturated.
