Abstract
The author offered designs of new burners on the basis of a nozzle with the central body such as NFB (the turbulent firing burner) and CBN (the centerbody nozzle). The article deals with the application of burner’s types NFB and CBN, and the basic principles of the theory of high-speed energy-efficient natural gas combustion are given. Designed burners NFB and CBN and their modifications utilized in rotary lime and rotary cement kilns use the so-called «normal» combustion as well as elements of detonation combustion. This effect is achieved through the formation of crossed shock with the creation of a powerful wave (the shock adiabat or Hugoniot adiabat), resulting in accelerated heating of the mixture. Constructive features of designed burners, which are used over the years and bring significant economic benefits, are represented.
