boiler slag

Boiler slag is a coarse, granular, incombustible by-product of coal combustion and is thus classified as a coal combustion byproduct.It is angular, dense, and very hard.Boiler slag is only produced in a wet-bottom boiler, as this boiler has a special design that keeps bottom ash in a molten state until it is removed. Essentially, boiler slag is what bottom ash turns into in very specialized ...

Boiler Slag. Boiler slag is the molten bottom ash collected at the base of slag tap and cyclone type furnaces that is quenched with water. When the molten slag comes in contact with the quenching water, it fractures, crystallizes, and forms pellets.

A cyclone furnace consists of a horizontal cylindrical barrel attached through the side of a boiler furnace. The cyclone barrel is constructed with water cooled, tangential oriented, tube construction. Inside the cyclone barrel are short, densely spaced, pin studs welded to the outside of the tubes.

Boiler slags are predominantly single-sized and within a range of 5.0 to 0.5 mm (No. 4 to No. 40 sieve). Ordinarily, boiler slags have a smooth surface texture, but if gases are trapped in the slag as it is tapped from the furnace, the quenched slag will become somewhat vesicular or porous.

Boiler slagging and fouling are some of the major operations and maintenance factors that can negatively affect power plant reliability and efficiency. ... Slag is molten ash and incombustible ...
