And there are now 78 countries using coal power, up from 66 in 2000. Another 16 plan to join the club, notably Egypt and the United Arab Emirates. CO2 emissions from existing plants are enough to breach the carbon budget for 1.5 or 2C. These limits would mean no new coal plants and closing 20% of the fleet early, according to one recent study.

Slagging occurs when coal ash accumulates at high temperatures outside the tubes that carry steam inside a power plant boiler. Slagging reduces heat transfer from the flue gas to the steam tubes and decreases a plant's efficiency. In extreme cases slagging can require a boiler to be shut down while heat transfer surfaces are cleaned or repaired.

Boiler Slagging. Power boilers experience slagging as the molten ash adheres to the surrounding substrates. This is also commonly referred to as slag. The amount of slag is primarily dependent on temperature and the types of coal being used and whether it is anthracite, bituminous coal, subbituminous coal, or lignite.

Boiler Slagging

Boiler Slagging

Slagging Propensity. 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 100°F to 150°F below the ash softening temperature.

Slagging and deposition in coal fired boilers is a complex phenomenon. The reasons can be due to coal characteristics, operating conditions, the design of the boiler furnace, or can be a combination of any of the three with others or all.When heavy deposition or slagging starts in the boiler, the boiler operating group can contain the problem, to a large extent, by taking corrective action.

Coal fired boilers experience deposition and slagging depending upon the ash characteristics of ash in the coal being fired. In many cases the operating parameters also play a major role. The molten or partial melting pasty ash deposits in radiant heat transfer surface like boiler furnace is termed as slagging. The sintered ash deposit in the convection region in boiler is called fouling.
