CO & O₂ Combustion Monitor
Accurate and reliable CO measurement is key to improving combustion. The EES Delta Measurement system provides data for continuous combustion tuning and optimization allowing plants to operate closer to ideal fuel to air ratios without unit damage resulting in the following benefits:
- Reduced NOx emissions
- Improved heat-rate or fuel efficiency
- Reduced FEGT and slagging
- Improved reliability and availability, reduce de-rates
- Decrease in water-wall wastage and tube leaks
- Reduction of LOI
Dry extractive O2 measurement ensures boiler operation in the optimized combustion zone. EES Delta Measurement's dry extractive O2 measurement probes utilize an in-line zirconium oxide sensor and can continuously measure O2 in furnace areas where conventional O2 probes cannot.
