TECHNOLOGIES
Continuous Emission Monitoring
Methods
Dry extractive
+ Low cost NDIR analysers can be used
- Not suitable with high dust loads
-Water removal changes the sample condition
Wet-hot extractive
+ Multigas analysers can be used
- Expensive
- Hot sample requires advanced heating systems
- Sensitive for power failures and high dust loads
Dilution extractive
+ Ambient type analysers can be used
+ Sample is dry and clean
+ Low initial cost
- Requires correct dilution
- Not suitable for monitoring low concentrations
In Situ Probe Type—diffusion
+ Simple installation
+ Low cross interference sensitivity
- Limited number of gases can be monitored
- Some models do not meet US EPA requirements
- Not representative sample
- Analyser stack mounted ( vibrations, temperature)
In Situ Cross Stack Type—Spectrometer in Stack
+ Representable sample
+ Meeting US EPA calibration requirements
+ TUV approved
Analyser Stack Mounted( vibrations, temper)
- Limited number of gases can be monitored
In Situ Cross Stack Type—Spectrometer in A/C Room
+ Reliable ( analyser not stack mounted ( OPSIS)
+ Representable sample
+ Meeting US EPA calibration requirements
+ TUV approved ( OPSIS)
+ Several hundreds of references world-wide
- Cross interference possible ( non-DOAS systems)
