    The lime kiln is a large, horizontal steel cylinder with a diameter of 2-4 meters and a length of 40-120 meters. The cylinder rotates at 1-3 revolutions per minute with a slope of 2-30 towards the burner. Some of the most difficult applications for valves are found in the white liquor plant. The green liquor is very erosive and has a strong

    The green liquor is first transferred to a slaker tank, where Ca0 from the lime kiln reacts with water to form calcium hydroxide (Ca(OH)2). From the slake, liquor flows through a series of agitated tanks, referred to as causticizers, that allow the causticizing reaction to go to completion (i.e., Ca(OH)2 reacts with Na2CO3 to form NaOH and CaCO3)

    A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction can take place at anywhere above 840 C (1544 F), but is generally considered to occur at 900 C(1655 F) (at which temperature the partial pressure of CO 2 is 1
