Neil Widmer, Product Line Manager GE Environmental Services’ Boiler Optimization Service Group, presented the latest applications and results of GE’s Zonal™ Combustion Tuning System on coal-fired boilers. The Zonal™ Combustion Tuning System provides tools to measure CO and O2 profiles in the exhaust of boilers to a degree that hasn't been done before and to advise plant operators on burner and overfire air adjustments, which can maximize performance and reduce operating costs.
GE’s Zonal Combustion Monitoring Application Experience includes
Coal Type – Bituminous or Subbituminous
- Ash < 30 %
- Moisture < 30%
- Sulfur < 3% (up to 4%)
Biomass co-firing to <30%
Gas Temperature: 900°F to 1300°F (1500°F maximum)
Other Considerations:
- Ammonia bisulfate impact from SNCR unknown
- Heavy oil co-firing impacts on filter maintenance unknown
--Distillate and start-up shown to be acceptable
- Ambient Environments
--Electronics rated 0° to 60°C, avoid exposure to severe weather.
--Installations to 20°C but not recommended.
--Sensor rated - 18° to 93°C. |
