Scrubber
Schematic of Scrubber
The WFGD test facility is connected to a 400,000 Btu/hr down-fired combustor that is capable of firing natural gas and solid and liquid fuels. SO2 can be injected at various locations within the combustor to simulate flue gas having an elevated SO2 concentration. The combustor has several sampling ports from which particulate and gas samples can be taken. Diagnostics include:
- Continuous emissions monitoring of CO, CO2, O2, SO2 and NOx
- Temperature profiles
