Point T in Figure 1 represents the triple point of water (at 0.01 °C and 0.612 kPa) where the three phases (liquid, vapor, solid) coexist, and point C is the critical point of water (374 °C and 22060 kPa). Freeze-drying makes use of the sublimation phenomenon (at temperatures lower than 0.01 °C, and water vapor pressures below 0.612 kPa).

Pulverization is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more …
Boilers E-240-13.8-560KT with a tangentially fired furnace were designed to burn Kuznetsk bituminous coal and operate as part of 65 MW units. Features of the …
We investigated the mechanical movements of the pinnae and petioles in M. pudica induced by the electrical stimulation of a pulvinus, petiole, secondary pulvinus or pinna by a low electrical voltage and charge. The threshold value was 1.3-1.5 V of applied voltage and 2 to 10 microC of charge for the closing of the pinnules.
Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal …
Pulverized coal is used in modern thermal power plants. It is a powdered form of coal i.e., coal that is grounded into a dust-like size. The pulverized coal is then conveyed to the furnace by way of a stream of hot air. An important purpose of pulverization is to expose a large surface area to oxygen, thus aiding in the burning …
In order to protect the coal pulverizer lube system components, Pall recommends maintaining a fluid cleanliness level of ISO 16/13 or better. This can be accomplished through the use of Athalon AS grade (ß12 (c)≥ …

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.
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].
