The emission and measurement of polyaromatic hydrocarbons is a topic of increasing concern to those in the industrial combustion business.

This week sees the publication of the first of a planned cluster of Combustion Files dealing with the topic of PAHs.

“CF190 What are Polycyclic Hydrocarbons (PAHs)?“ is a general introduction to the topic, prepared by University of Glamorgan’s Patrick Lavery, currently on EuroFlam duties with IFRF NET at the Communications Centre.

This first PAH CF has been refereed by ENEL’s Loretta Bonfanti, who is also engaged in preparing additional material on PAHs for publication in the coming months.

You will find CF190 in the ‘New Combustion Files’ area of the IFRF Combustion Handbook at www.handbook.ifrf.net.

This is an ‘Open Domain’ publication that can be read by IFRF Individual Members and non-members alike.

This week also sees the continuation of the development of the ‘In Flame Measurement Techniques’ theme within the Combustion Handbook with the publication of two further combustion files dealing with the application of Laser Sheet Visualisation in industrial scale flames.

These techniques were demonstrated and developed at the IFRF Research Station in the 1990s, and build on a long tradition of developing in-flame measurements techniques extending over five decades. Jacques Dugué of Air Liquide, leader of the IFRF team that undertook this work, has co-authored five Combustion Files on this topic. The two published today are:

CF133: How do I use Laser Sheet Visualisation data to quantify mixing in a flame? – Members’ Domain
CF134: How do I quantify Intermittency and Unmixedness using Laser Sheet Flame Visualisation? – Members’ Domain

You will also find the three complimentary files in this cluster listed in the ‘New Combustion Files’ section of the handbook.

CF119: What is Laser Sheet Flame Visualisation? – Members’ Domain

CF203: How do I apply Laser Sheet Visualisation in industrial flames? – Members’ Domain

CF222: How do I apply Laser Sheet Visualisation to industrial scale liquid sprays and soots? – Members’ Domain

To view the LSV files, go to www.handbook.ifrf.net, and select New Combustion Files option on the left hand menu after agreeing the disclaimer. You will need an individual IFRF Members password to read or download these files.

Further Combustion Files on this topic can be listed by selecting Search Combustion Files and searching on the keyword ‘measurement’. These include a number that are in the public domain.
