Flameless combustion, or moderate or intense low oxygen dilution combustion, is an advanced technology that meets all the conditions for being an important actor in the researchers’ efforts to develop low level of polluting emissions and high thermic efficiency combustion systems. Because all the factors that contribute to the emerge of this kind of combustion are not completely understood, there is the suspicion that this type of combustion could be achieved only by overheating the combustion air, which generates the limitation of this technology’s application area. After all the last years conducted research, it came to the conclusion that the requirements for this combustion are less severe than they were believed to be. The recent research is conducted towards the use of this type of combustion for all type of fuels, gas, liquid and solid.
