Anthracite Coal Characteristics and Applications
Know More
Anthracite is considered “nonclinkering” and free-burning because when it is ignited it does not "coke" or expand and fuse together It is most often burned in underfeed stoker boilers or single-retort side-dump stoker boilers with stationary grat Dry-bottom furnaces are used because of anthracite's high ash fusion temperature
