Coal Boiler Slag

The Finished Part: Coal Slag

2020-5-7 · Boiler slag is the molten material (ash and incombustible) that is sent to a quenching water bath. The quenching process immediately fractures the molten material producing a coarse, hard, black, angular, glassy material sometimes call black beauty. This coal slag is used for a variety of industrial applications including abrasive blasting.

Frequently Asked Questions | What is Coal Slag? | US

This stuff is boiler slag, which is a recycled product from coal burning plants. When coal is "fired" at over 2500 degrees it melts and produces a by-product called slag. When the slag is cooled through a process called vitrification, it crystallizes, forming sharp, angular granules in a variety of sizes.
