Abstract
A dam surrounding a slag tap on a refractory covered, boiler-tube floor for holding back a protective slag layer. The dam is comprised of a plurality of adjacent refractory blocks mechanically secured to the refractory covered, boiler-tube floor near the slag tap. Each refractory block is shaped to brace an adjacent refractory block against motion toward the slag tap. Additional dams are used when a single dam is not sufficient to cover the entire surface of the floor with slag.
