Calcination - Burning Limestone | Unity Lime

Heat transfer for lime burning can be divided into three main stages: 'Preheating zone' - limestone is heated to approximately 800°C by direct contact with gases leaving the calcining zone. 'Calcining zone' - fuel is burnt in preheated air from the cooling zone. This produces heat at above 900°C and turns limestone into quicklime and CO2.
