Abstract (English)

CATHLEAN addresses the research and development of an advanced, ultra-low NOx, hybrid burner for gasturbines, which combines catalytic and lean-premix combustion technologies. Such a hybrid design enables this new technology to be introduced in a low-risk manner.

The catalytic elements serve to pre-treat the fuel, which can be natural gas, biogas, syngas, or mixtures thereof, in order to enhance performance in terms of :
- emissions (<3ppmv NOx and <10ppmv CO @ 15% O_2 at 100% load, for natural gas fuel)- part-load stability (reducing the temperature at which lean blow out occurs for lean-premixed flames, byover100°C)- thermoacoustic phenomena (pulsations < 0.3% of pressure).The principle scientific objective is to quantify, both experimentally and numerically, the technical advantages of hybrid burner in terms of the three above-mentioned criteria, relative to traditional, lean-premixed combustors.
