Vertical lime kiln coal firing combustion chamber

contacts the combustion gases and the lime mud as the kiln rotates, it is effective. Like any low-temperature heat exchanger, it is the available surface area that is most important to effectiveness. The chain surface area in a lime reburning kiln can represent two-thirds of the entire heat transfer surface. ROTARY KILN REFRACTORY SYSTEMS
