Research on the Three Different Kinds of Technologies to Achieve Flameless Combustion and Their Applications

Flameless combustion was first to developed suppress thermal NOx formation and raise the efficiency of combustion. Now in further research, three different combustion technologies can be used to achieve flameless combustion those are high temperature air combustion (HTAC), normal temperature air combustion (NTAC) and oxy-fuel flameless combustion. This paper presents a description of the three different technologies, the development of their application in gaseous, liquefied and solid fuels combustion as well as their industrial applications at a research stage. These flameless combustion applied combustion technologies guarantees the uniform temperature distribution, fuel consumption reduction and productivity when applied, for example, to coal gasification, and to low calorific fuel combustion.
