We must therefore get energy into the process as well as extract energy. This chapter examines the energy source and supply required to sustain the operation for which the dominant source is fossil fuel combustion. Herein, the basics of combustion and the flame that develops and forms the heart of the direct-fired rotary kiln are presented.
Nelson Machinery supplies Rotary Dryers worldwide in a wide range of sizes. Gas fired and dual fuel dryers available with stainless steel for some units. The rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas.
Direct Fired Rotary Calciners. A directly heated rotary dryer from Thermal Processing Solutions can be gas or oil fired, or hot air utilizing a heat exchanger or heating elements fired in a parallel flow or counter flow arrangement. Utilization of a heat exchanger allows the use of a dry gas such as air or nitrogen as the heat transfer media.
The Hurst STAG unit can be utilized from 5 MMBTU/HR - 250 MMBTU/HR with operating temperature ranges from 200°F to 2000°F. These system are frequently utilized in lumber dry kilns, boiler applications, oil heaters, rotary dryers, brick kilns and much more.
Rotary kilns are designed to withstand much higher temperatures than a rotary dryer. Typically, if you are dealing with a direct fired rotary kiln, it is refractory lined with a brick or castable lining. This lining protects the steel shell. Rotary dryers are typically not lined, and their steel is not able to withstand such high temperatures.
Rotary kilns can be either of the direct-fired type, or the indirect-fired type (sometimes referred to as a calciner). In a direct-fired kiln, a process gas is fed through the drum, processing the material via direct contact. In an indirect-fired kiln, material is processed in an inert environment, and is heated through
General layout of a direct fired countercurrent rotary kiln used in cement manufacture Rotary kiln body, with drive gear and 2 tyres (riding rings) A rotary kiln is a pyroprocessing device used to raise materials to a high temperature ( calcination ) in a continuous process.

Emissions from kilns and dryers include wood dust and other solid particulate matter (PM), VOCs, and condensable PM. If direct-fired units are used, products of combustion such as carbon monoxide (CO), carbon dioxide (CO 2), and nitrogen oxides (NO x) are also emitted. The condensable PM and a portion of the VOCs leave the dryer stack as vapor ...
