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.
Indirect-fired rotary kilns (furnaces) Rotary kilns (furnaces) of indirect heating are used for drying different friable materials as well as heating them up to temperatures required for different technological processes. In rotary kilns of indirect heating processes of heat production take place outside the case of the rotating furnace.
Indirect-fired rotary kilns can be beneficial when the material to be processed consists of finely divided solids. In a direct-fired rotary kiln, the heat source is hot gas (products of combustion and air) which flows with an inherent velocity. These gases can carry discrete particles through from drag.
Other typical indirect fired rotary kiln applications include chemical laden soils, absorbents, tank wastes, and other inert substrates. As these examples indicate, there are countless applications wherein an indirect fired rotary kiln may result in a more cost effective system overall. The developer of a thermal process must take into account

Dec 26, 2019· Rotary kiln can be either of the direct-fired type, or the indirect-fired type. In a direct-fired kiln, a fuel is burnt in the drum, and the material is processed through direct contact with the flue gas. In an indirect-fired kiln, material is processed in an inert environment, and is heated through contact with the shell of the kiln, which is
The kiln is fired by gas burners directly against the outer shell of the vessel. The temperature inside the kiln is controlled by adjusting the burner heat, varying concentration of O 2 in the oxidizing medium and its flow. The indirect fire kiln comprises a double-shell cylinder vessel. The inner shell is similar as that of the direct fire kiln.
