Improving the fuel efficiency of a fluidised bed annealing furnace

摘要

Recent research on heat transfer rates to wires in a fluidised bed has shown that modulating control or staged control of fluidised beds used for heat treating wire is feasible. The benefits of using these control schemes include a substantial reduction in fuel use, and a corresponding reduction in harmful emissions. New furnaces can be built to operate using these control schemes at minimal cost, and existing furnaces can be easily modified in most cases.
