It's no secret that excessive boiler deposits can lead to serious reliability and performance issues for power plants. Regular boiler maintenance that includes thorough boiler cleaning will lead to lower operating costs, reduced fuel consumption, greater efficiency, and a longer lifespan of the boiler. Over time, the burning of coal, bio-mass and other solid fuels creates molten ash. The ash accumulates to create a stony buildup on the furnace walls of the boiler known as slag. Slag may also fuse to the fire side of the boiler tube, preventing sufficient heat transfer. A reduction in heat transfer from the flue gas to the steam tubes can cause lower boiler efficiency, hotter flue gas temperatures and, in some instances, a boiler shutdown. What's more, slag causes boiler corrosion, which can lead to unexpected failures.
