Anti-fouling coatings for combustion system components exposed to slag, ash and/or char

摘要

A coating for use in combustion systems includes a plurality of refractory metal particles in a ceramic, glass or metal matrix disposed on surfaces of the system that are prone to slag, ash, and/or char buildup during operation of the combustion system. The coating is effective to prevent any substantial interaction with the slag, ash, and/or char.
