Indirect Fired Rotary Kilns zoom In contrast to directly fired kilns indirect fired rotary kilns also called rotary calciners are equipped with natural gas burners or electric heating elements located outside the reaction chamber so that the heat is transferred to the interior through the kiln shell
How the Indirect Heat Dryer Works Materials are fed into a rotary drum that is encased in a stationary refractory lined furnace This furnace casing has a series of burners mounted down the length of one side firing into the furnace chamber
