Today we have published a new article in the IFRF Online Combustion Journal entitled:

Radiant Tube Technology for Strip Line Furnaces

Ambrogio Milani
and Joachim Wünning

The article reviews the modern technology of radiant tubes with an emphasis on heat recovery and low-NOx combustion techniques, including flameless combustion.  Performance of radiant tubes is of basic consequence in large strip line furnaces. The combustion pattern inside the tube, as well as connection of many tubes to the furnace, play a crucial role.

The article assesses the features related to this topic, from main design concepts to the materials available for radiant tubes, from energy saving measures to abatement of NOx emissions and flame/plant control.  Significant applications to large industrial plants are reported, as well as on-going development of new products.

Industrial practice and field feed-back point out that additional investment costs for an efficient and reliable radiant tube system can be recovered in a few years and provide better quality and operating conditions.

Publication in the Journal
The Editor-in-Chief would like to remind potential authors that publication in the Journal is open to all. If you have interesting results to publish in the field of, or related to, industrial combustion, we invite you to prepare a paper according to the guidelines given in the Author’s Guide on the website

Papers may be regular “articles” (typically up to 20 pages) or “Communications” (typically up to 4/5 pages). Review papers can of course be longer. Remember that figures and graphics in general can be in full color. This advantage should be encouraged.

All manuscripts and associated files, proposed for publication should be sent by the Corresponding Author in a compressed/zip file, as an email attachment to journal@ifrf.net. This file should include a statement that the proposal’s content is unpublished material that has not being submitted for publication elsewhere. When an article by the author(s) is cited in the proposed article as “in press”, a copy of this article should accompany the proposed article and should be included in the compressed file.

The Editor-in-Chief looks forward to receiving your proposals.
