Slagging and Fouling in Coal Fired Boilers - Bright Hub

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. Coal

Failure investigation of super heater tubes of coal fired

Failure of super heater tube of boiler is the major concern of forced outages at coal fired thermal power plant. Flue gas passes over super heater tubes leading to damage over the time of operation and termed as fireside damage/corrosion. Again the extent of damage is dependent on quality of coal, materials used, operation and maintenance.

How to Destroy a Boiler -- Part 1

Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.
