Title: High temperature corrosion during use of chlorine containing coal

DOI:https://doi.org/10.2172/5767735· OSTI ID:5767735

The goal of this project is to characterize the role of chlorine in coal on the high temperature corrosion processes which can occur in coal combustion and conversion processes. The experiments include laboratory tests performed in well-controlled high temperature environments and field tests in industrial coal fired boilers. Evaluation of samples of boiler tubes which have been recovered from boilers which used both high and low chlorine coals does not indicate that the higher chlorine levels are associated with accelerated corrosion of either water wall tubes or superheater tubes in pulverized coal boilers. Laboratory testing of metal coupons in combustion gas environments produced from low sulfur, high chlorine coal IBC-109 and high sulfur-low chlorine coal IBC-101has been performed at 800{degrees}C. No significant difference in corrosion are evident. Further testing at other temperatures and gas compositions is underway.
