The burning velocities of stoichiometric methane/air, methane/air/ exhaust and methane/air/exhaust/reformer gas mixtures have been measured using a constant volume cubical combustion chamber. The flame size and burning velocities were calculated from the chamber pressure record using a multi-zone thermodynamic equilibrium model. The investigation measured the decrease in burning velocity due to addition of EGR and the quantity of reformer gas/air (RG) required to raise the burning velocity back to undiluted level. The burning velocity dropped from around 35 cm/s for stoichiometric methane/air mixture to about 13 cm/s if 20% EGR was added to the mix. At about 20% EGR fraction, 42% RG was required to bring back the burning velocity to the original undiluted level.

Key words:

burning velocity, methane mixtures, exhaust gas recirculation

Publication in the Journal

The Editor-in-Chief (See associated article in this edition of the MNM) would like to remind all 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 (http://www.journal.ifrf.net/).

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 This file should include a statement that the proposal’s content is unpublished material that has not being submitted for publication elsewhere.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.
