Asec Academy Coal Preparation In an inert coal grinding plant the temperature of the drying gas can to some extent be reduced either by adding cold, atmospheric air or by recirculating the mill exit air. The dew point of the exit gas when using cold atmospheric air is lower than when using recirculation air.

In common terminology in the field of coal combustion, the term "dew point corrosion" is synonymously used with sulphuric acid dew point corrosion. This clear correlation has to do with the chemistry of coal as a fuel. If reference is made to the dew point of water, the "water dew point" is expressly referred to. These common references to dew points and to sulphuric acid as the cause ...

These are returned to the product coal. All secondary emission control systems are wet collectors. The high dew point and explosion potential of the exhaust gas make other emission control systems impractical. The dried coal is conveyed to storage where it remains until being loaded into railroad cars, trucks, or barges. Dry Cleaning Systems ...

Particulate Removal. Particulate matter (PM) consists of microscopic solid particles or liquid droplets which are small enough to enter the lungs and cause health problems. Both nitrogen oxides (NOx) and sulfur oxides (SOx) are associated with the formation of particulate matter, but other processes can contribute to their formation.
