This week, the IFRF publishes two new reports relating to the High Efficiency Combustion (HEC) Project .

Laser Based Measurement of HEC-EEC Burners and Furnace
The combination of compact regenerative burners with flameless firing delivers the high thermal efficiency needed for reducing carbon emissions and fuel costs while at the same time reducing NOx emissions. The IFRF Research Station is undertaking detailed measurements and modelling of such a system in its new High Efficiency Combustion (HEC) furnace, the objective being to provide generic information on the combustion behaviour of regenerative flameless combustion systems, together with data that may be used to develop and validate mathematical models of such processes. Although the HEC furnace design is intended as a simulation of a large steel reheating furnace, it is anticipated that the output from the HEC tests will find application over a wide range of industrial processes.
The first report C108/y/2 completes the description of the design, installation and commissioning of the new HEC furnace and its flameless regenerative burners. This report and the earlier C108/y/1 report already published contain an extensive description of the furnace and the burners as well as their operation.

The second report F108/y/1 deals with the results of the laser based measurements undertaken on the HEC Furnace. Laser Sheet Visualisation (LSV) and Laser Doppler Anemometry (LDA) measurements have been performed to determine the flow patterns inside the HEC burner and furnace, and to quantify the velocities at the burner exits and within the combustion chamber. These measurements have been performed under two circumstances:
