Modelling and optimization of a rotary kiln direct reduction
The kiln model applied in this work was developed by Hatch over a number of years and has been used for several rotary kiln projects. It has its roots in a FORTRAN program that was developed by Venkateswaran (1978) to study the reduction of iron ore. The original software was used to model the operation of a 35 m pilot kiln at the Stellco company

How the Pyrolysis Kiln is Contributing to a Circular Economy
How a Pyrolysis Kiln Works. Rotary kilns carry out pyrolysis at temperatures ranging from 800°F to 1400°F. Because pyrolysis is a "starved-air" process, meaning it occurs in the absence of oxygen, the rotary kiln must be carefully sealed to create the necessary inert processing environment.
