The impact of near-wall air on pollutant emissions and high-temperature corrosion in opposed-fired boilers

Key Points

• Pollutant emissions increase due to altered thermal dynamics with near-wall air exposure, affecting efficiency.
• High-temperature corrosion is exacerbated under certain conditions in opposed-fired boilers with near-wall air.
• Observational analysis conducted on opposed-fired boilers revealed significant interactions with environmental factors.
• This research highlights the need for improved designs to mitigate corrosion and emissions in industrial boiler systems.
