... such as fusion, solidification, evaporation, or condensation will occur, and absorption or emission of a specific heat quantity can be observed. This heat quantity was called “latent heat” in the past. However, because latent heat is the change of enthalpy in accordance with phase transformation as described...

... and interpretation of phase diagrams. The thermodynamic quantities that are most frequently used in materials science are the enthalpy, in the form of the heat content of a phase; the heat of formation of a phase, or the latent heat of a phase transformation; the heat capacity, which is the change of heat...

... with the introduction of air for combustion from the bottom of the bed, the coal will burn rapidly, forming a combustion bed. Fluidized bed combustion takes place at about 850 to 950 °C (1560 to 1740 °F). Because this temperature is below the ash fusion temperature, melting of ash and associated problems are avoided...
