Use of regenerative burner systems in batch-wise furnace operation

The use of regenerative burner heating systems in continuously operated plants in the steel and forging industries is tested in practice over the years. Due to the enormous energy savings with correspondingly large power requirements, and the continuous mode, these systems are used very successfully. In batch-wise operation, especially in the forging business, this system was rather uneconomical due to the batch operation and the cost situation. Due to the development of combination burner, regenerator and regulation a system was developed that in the light of rising gas prices and the demand for emission reduction also allows the use in batch-wise operation. The system at Saarschmiede and Böhler Edelstahl will be presented.
