Abstract The model particles were prepared by oxidation of carbonyl iron spheres, followed by fractionation into cuts of very narrow size. A two‐wavelength radiation pyrometer was developed for measuring the temperature of the particles in flight, and special probes were designed for determining gas velocity and degree of reduction at different levels of the reactor.
