Mechanochemical synthesis of one-part alkali

 · The critical speed (rpm) was calculated as n c = 42.29/ (sqrt d) where d is the internal diameter of the milling jar (in meters) . Dry grinding was performed at about 75 of the critical speed. The mill was filled with balls and materials to 40–60 of its volume. Ball-milling was carried out over a 2-h period.

 · The A–E elevations of burners are put into operation under the rated load and the burners on F elevation are out of service. Six set of medium-speed coal mills are employed to supply the coal–air mixture to the corresponding elevation of burners. The dimensions of the furnace and the arrangement of the burners are illustrated in Fig. 1.

Pulverised Coalan overview ScienceDirect Topics

Coal dried with air at 250–350°C for milling in low- medium- or high-speed mills. Main milling costs are power and replacement of worn parts. Wear depends on fineness of grinding and on hardness and abrasiveness of coal. Coal and air distribution to burners must be uniform to avoid local reducing zones which encourage slagging.

Theoretical Airan overview ScienceDirect Topics

The heating or calorific value of a fuel can be determined experimentally in a calorimeter or from its chemical analysis. The high or gross heating value (HHV) is the total heat released of a perfect mixture of fuel and air originally at 60°F and then cooled to the same temperature. The low or net heating value (LHV) is equal to the high heat value minus the heat released by condensation of
