This paper aims to clarify the mechanisms governing the calcination and sulfation of limestone during oxy-fu el combustion. Apart from pure limestone, the mixtures of limestone with a low-rank brown coal at three different mass ratios were combusted in an lab-scale drop-tube furnace (DTF) to systematically examine the influences of a
The IUPAC defines calcination as "heating to high temperatures in air or oxygen". However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature ...

Mega-crystalline calcite (m-CC) breaks apart easily during calcination, and is converted to CaO with difficulty due to its thermal decomposing characteristics that necessitate large heat consumption. To overcome this problem, m-CC was calcined using either a microwave furnace or an electric furnace for 15 min and 30 min at 950 °C.
limestone sample was moved into the calcination furnace quickly once the test temperature was reached and stabilized. Once the weight loss stopped (signaling the end of the
The kinetics of calcination of a high calcium type of limestone was studied. Ukpilla limestone found in the central region of Nigeria was studied. The limestone composition shows that the limestone has 51.29% calcium oxide and 41.53% loss on ignition and magnesium oxide content of 2.23%. The following parameters were
