- •
Ash deposition during oxy-firing was explored in a 100 kW test rig outfitted with various flue gas recycle options.
- •
Relationships between the size segregated ash aerosol and the spatially resolved deposit were determined.
- •
Oxy-firing caused only minor changes in the compositions of the bulk ash aerosol, bulk fouling and slagging deposits.
- •
Changes in the compositions of the sub-micron aerosol and the inside deposit were caused by changes in the RFG amounts.
