Pellet production is an intensive energy process. Although, pelletizing it is a highly energy optimized process, producers are facing restriction due to restrictive environmental standards in the whole world. In order to deliver solution to this relevant topic, Outotec is developing in small scale the low NOx burner since 2012, and the expressive results are reached. In 2014 using CFD simulation, the small scale results were reproduced with very good adherence and the results of industrial scale simulation shoed the same behavior as well, it showing promising too. The present work shows the development steps, the promising results and the next step of this development is to make an industrial test of the burner developed.
