What is 'Green Coal' and a 'Clinker?' - Trainorders.com Discussion

A clinker is caused when coal melts together instead of burning. The clinker thus cause a cemented-over area on the grates where absolutely no air can pass through. An "old head trick" sometimes used to break-up a large clinker, was to squirt the clinker with cold water from the Fireman's deck hose. The quick blast of cold water will generally ...

Coal Forges - Moose Forge

A clinker is coagulated slag or metal impurities that "melt" from the coal as it becomes coke. Most clinkers consist of pyrites that are naturally included in coal seams. Using "metallurgical" grade coal (met coal) greatly reduces clinkers. Clinkers will block air flow from the tuyere and that is why the firepot has a clinker breaker.

Definition of clinker

Glassy clinkers, that are sometimes named scoria, are in fact buchites. Characteristic features of clinkers is its resemblane of pavement brick (klinkaerd) and a "metallic" sound when hit by a hammer.
