Water Handbook - Coil-end Deposition and Corrosion

Consequently, dew points are raised. 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

Coal Grinding - Cement Plant Optimization

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...

Fuel Ash Corrosion - National Board

For hydrochloric acid, the dew-point may be as low as 130 o F. While the precise dew-point for sulfuric acid depends on the sulfur-trioxide concentration, at 10 parts per million sulfur trioxide in the flue gas, the dew-point is 280 o F. Dew-point corrosion is exacerbated in coal-fired boilers by the presence of fly ash.
