Scrubber

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 NO_x
Temperature profiles
