Boiler Slagging

The root cause of furnace slagging is actual very simple, slagging will occur if furnace exit gas temperatures (F.E.G.T.) exceeds the fusion temperature of ash from the coal being fired. To ensure operation without slagging, we typically recommend that F.E.G.T. be 100F to 150F below the ash softening temperature.

Characterization Of Coal Ash Including Fly Ash Particles

furnaces after the molten slag comes in contact with quenching water. Boiler slag is generally described as a black granular material made up of hard, black, an-gular particles that have a smooth, glassy appearance. FGD materials are generated during the reduction of SO 2 emissions from the exhaust gas streams of coal-fired boilers.

Fireside Corrosion

Ensuring the furnace exit is an Oxidizing atmosphere is also of critical importance in reducing Carbon in flyash, reducing formation of CO and prevention of coal-ash corrosion. With a reducing atmosphere (0% oxygen) slag is forming on the nose arch because the melting (fusion) temperature of the ash is lower in the absence of oxygen.

One of the possible solutions would be to reduce the proportion of clinker in the cement, by replacing it with materials such as coal fly ash, steel slag, rice husk ash and volcanic ashes 19. As most of the CO 2 emissions are related to the clinker production, decreasing clicker-to-cement ratio could significantly reduce such GHG emissions.
