The actual kiln tests do not show (by difference) a steady value for the exothermic reaction during clinkering All the essential heat quantities except the exothermic reaction are measured during a test, and the practice has been to denote by "exothermic reaction" the amount by which the heat which is calculated to be necessary exceeds the heat due to the coal which is actually burnt in the kiln

 · The ammonium carbonate first reacts with CO2 to form ammonium bicarbonate and the latter reacting with salt, forms sodium bicarbonate. The heat of exothermic reaction is removed by cooling coils. Filtration: Filtration NaHCO3 slurry is then filtered on a rotary vacuum filter which helps in drying of bicarbonate and in recovering ammonia.

Graeme Moir, in Advanced Concrete Technology, 2003. The modern rotary kiln. The rotary kilns used in the first half of the twentieth century were wet process kilns which were fed with raw mix in the form of a slurry. Moisture contents were typically 40% by mass and although the wet process enabled the raw mix to be homogenized easily, it carried a very heavy fuel penalty as the water ...

 · Special ports are built into the side of the kiln. At the point when the kiln is nearing the highest part of the fire (generally near cone 9 or 10), the ports in the kiln wall are opened and salt is forced into the kiln. The salt reacts very strongly to the heat of the fire and breaks into its component parts, sodium and chlorine.
