This paper presents the potential for energy savings in various capacity sponge iron plants by estimating heat transfer rates using stabilized and optimized temperature data within the rotary kiln/reactor. Air jet seal instead of mechanical seal arrangements at specific locations in the rotary kiln and cooler are proposed and this is shown to reduce the power consumption and the size of the centralized grease lubricating system. The paper proposes atomized water spray on the post combustion chamber instead of larger droplets to reduce the size of the water handling system, thereby saving energy. The paper also suggests optimization of the performance of a pneumatic coal injector by optimizing coal and air quantities.

In the present study, dc high voltage was applied to produce droplets with controlled diameter in wide range. The dc voltage was ranged from 0 to several kV. Water glass was atomized in alcohol solution into diameters of several ten μm, depending on dc voltage applied between nozzle and ground electrode. The atomized water glass droplets were solidified by removing water molecules from the water glass. When the dc voltage was raised, nozzle diameter and electrode distance were decreased, the diameter of silica particles was decreased.
