A lot of energy is required for drying the sewage sludge produced during the wastewater treatment process in China; however, on the other hand, the thermal energy in flue gas from power plants is usually wasted as it discharges into the atmosphere. In this study, a new technique for sludge drying is introduced. The key component of the new …

These technologies are seen as a major carbon mitigation route, as it is estimated that a percentage point increase in plant thermal efficiency can lead to a double reduction in CO 2 emissions [17]. Therefore, replacing old pulverized fuel (PF) plants with SC pulverized coal plants has the potential of reducing emissions by 10–25% [15].

Modern boilers powder the coal to a very fine dust so that while burning, it is almost like a fluid stream. The size of the coal particles is in the range of 75 microns. This means every particle comes into contact with the air. The loss due to unburned carbon is only in the range of 0.5 % or less making the boilers very efficient.

Pulverization. Pulverization takes place by impact, attrition, or crushing. Figure 1.12 shows a ball-race mill which grinds by crushing. The lower race is turned by a motor, causing the balls to rotate. Coal enters the center of the mill and is thrown out against the moving balls which crush it against the races.
