Water Handbook - Coil-end Deposition and Corrosion Control

With any type of fuel, corrosion and fouling potentials rapidly increase below gas temperatures of 140 degrees F (60 degrees C), which is the typical water dew point for flue gases. Cold-end corrosion and deposition are usually much less severe in coal-fired boilers than in oil-fired units.

Coal Drying Improves Performance and Reduces Emissions

The high temperatures developed in the relatively small boiler volume, combined with the low fusion temperature of the coal ash, cause the ash to form a molten slag, which is drained from the bottom of the boiler through a slag tap opening. Cyclone units have high nitrogen oxide (NOx) emission rates.
