The following report reviews modern technology of regenerative burners with emphasis on heat recovery and flameless combustion techniques for high temperature processes.

Performance of the combustion equipment are most important in large strip-line furnaces not only for energy savings and NOx abatement, but also for reliable, trouble free operation.

The paper describes a modern, compact regenerative burner that has been extensively installed and tested on industrial furnaces and assesses related features. Significant and successful applications to large Annealing and Pickling lines for stainless steel strip are reported.

Industrial practice and field feed-back point out that a modern, efficient and more reliable combustion system may be competitive and that possible additional investment costs can be recovered in a short time, while providing better quality and easy operating conditions.
