In conventional air-fired combustion systems a huge amount of the heat of formation is absorbed by nitrogen. Oxygen enhanced combustion (OEC) systems uses an O2/N2 mixture with a higher concentration of oxygen than in the ambient air. As a consequence, higher flame temperatures as well as an improved radiative heat transfer in the furnace can be determined when OEC is used. Therefore, OEC is an option...
This study was focused on the experimental investigation of the very promising combustion technology called as the oxygen-enhanced combustion (OEC), which uses the oxidant containing higher proportion of oxygen than in the atmospheric air, i.e. more than 21%. The work investigated and compared the characteristics of two OEC methods, namely the premix enrichment and air-oxy/fuel combustion, when the...
The aim of the present work was to experimentally investigate the combustion properties of methyl-ester of rapeseed oil (RME) that was preheated for three distinct temperatures ((30, 70, 110) °C) in the study. The experiments were carried out in a water-cooled horizontal combustion chamber with a nominal thermal load of 1500 kW. The experimental results were compared to the results obtained from the...
