METHOD AND SYSTEM FOR INJECTION OF EMULSION INTO FLAME Russian patent published in 2015 - IPC F23R3/34 F23D11/16 

FIELD: power industry.

SUBSTANCE: system for injection of emulsion from the first fluid medium and from the second fluid medium into the burner flame contains the central gas channel, the external gas channel, the fluid medium channel and the mixing device for formation of emulsion from the first fluid medium and from the second fluid medium and for release of emulsion into the narrowed circular fluid medium channel and for injection of emulsion from the named circular channel of the fluid medium into flame. The central gas channel passes along the longitudinal central axis from the end, from the upstream end towards the downstream end. The external gas channel is arranged coaxially with the gas channel. The fluid medium channel is located coaxially between the gas channel and the external gas channel with formation of the circular fluid medium channel which is narrowed downstream. The central gas channel and the fluid medium channel are divided by means of the first wall in the form of truncated cone on its downstream end, ended by the circular internal ledge. The fluid medium channel and the external gas channel are divided by means of the second wall in the form of the truncated cone on its the downstream end, ended by the circular external ledge. The system is installed with concentric enclosing of the heating source supplying hot gases directed to the burner flame through the gas channel.

EFFECT: invention reduces NOx emission from burning of the main flame.
