A detailed evaluation of furnace heating systems is presented.Topics of discussion include application guidelines for both gasfired and electrically heated furnaces. Heating system selectionconsiders operating temperature, processing atmosphere and heatingmethod (radiant or convective heating) along with heating systemorientation within the furnace chamber. The evaluation consists ofa comparison of operating costs, environmental considerations andlifetime maintenance costs of the various systems. Systems to beevaluated consist of alloy radiant tubes (single ended, U-tube,etc.), ceramic radiant tubes (single ended and U-tubes) and avariety of electrical element designs. Actual case studies of thevarious heating systems are presented with respect to maintenanceand operating costs.
