Fire - Wikipedia
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Fire is hot because the conversion of the weak double bond in molecular oxygen, O 2, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O 2); the bond energies of the fuel play ...

Clinker Production | Clinker Plant | Cement Plant Equipment
As the temperature of the material increases, the mineral becomes a liquid phase and reacts to form a large amount (clinker). After the clinker is fired, the temperature begins to decrease. As a leading cement plant manufacturer, AGICO Cement supplies cement equipment for clinker plant, such as cement rotary kiln, preheater in cement plant ...
Clinker Making | Industrial Efficiency Technology & Measures
Clinker is produced by sintering limestone (calcium carbonate) and clay (alumino-silicate) at elevated temperatures. The production of clinker involves the feeding of the raw meal into the kiln, where first the calcination of calcium carbonate takes place and then the resulting calcium oxide is burned at high temperatures together with silica, alumina and ferrous oxide to form clinker.
PORTLAND CEMENT
The plant average raw meal to clinker ratio is 1.59. The average total renewable and non-renewable primary energy required to produce a metric ton of clinker was calculated to be 3.88 GJ on a lower heating value basis. Table 2. Clinker production technologies applied in the making of the portland cement described by this EPD.
