FlexiFlame™ Burners FlexiFlame™ burners are the most advanced technology developed by Greco for rotary kilns firing pulverized fuel. Using three shaping airflows and a unique design – two of the airflows rotate to enfold the solid fuel injection flow – it allows, through simple procedures, to optimize complex fuel firing and great control over NOx emissions. FlexiFlame™ main features: • Greater control over NOx emissions • Enhanced control over ring formation • Greater control over the sulfur cycle • Better product quality • Longer refractory service life • Greater flexibility on flame control • Better process stability

FlexiFlame™ burners are customized to deliver thermal power up to 150 Gcal/h. They can use just one or multiple fuels, with variable mix, as: Dispersion air Velocity up to 175 m/s Tangential air Velocity up to 200 m/s Solid waste + conveying air Velocity between 35 m/s and 45 m/s External air Velocity up to 175 m/s Solid pulverized fuel + conveying air Velocity between 26 m/s and 32 m/s FlexiFlame™ burners were developed to meet, with flexibility and without any efficiency loss, the specific necessities of rotatory calciner kilns used to make white and grey clinker, lime and pozzolana,...
