اقرأ أكثرDefinition of Clinker. Clinker is a hard, black, or dark grey substance created when coal is burned. It's made of ash, soot, and minerals that fuse together at high temperatures. Clinkers can form on the fire grate, inside combustion chambers, or in flue pipes. These lumps can damage furnace components and reduce efficiency if not removed.
