Abstract

The invention relates to energy and can be used when burning fuel in heating furnaces. The purpose of the invention is to improve the quality of combustion. A shell 5 is rotatably mounted around the fuel supply pipe 2, installed in the zone of the tangential air supply pipe 3 and provided with an impeller 6 and shaft 7. The shaft 7 is installed along the axis of the housing 1 in the area of the nozzle 4, in which the guide blade 8 is inclined; rigidly bonded to the shaft 7. The fuel is fed through pipe 2, and the oxidizer through pipe 3. When the fuel encounters the oxidant, a fuel-oxidant mixture is formed, which burns in a flare at the outlet of the housing 1. At a tangential flow As an oxidizer, it rotates the impeller 6, the shell 5, the shaft 7 and the blade 8. When rotating, the blade 8 partially cyclically blocks the output section of the apparatus4, displaces the fuel-oxidative flow relative to the longitudinal axis and rotates it around this axis. At the same time, chemical underburning and the content of harmful gaseous products are reduced, and the quality of fuel combustion is improved by 2 sec. f-ly, 2 ill. (Ls

Claims (2)

Claim 1. A method of burning fuel by supplying fuel and an oxidizing agent along the longitudinal axis of the burner body and forming a fuel-oxidative stream, characterized in that, in order to improve the quality of combustion, the fuel-oxidative stream is displaced relative to the longitudinal axis and rotated around it. 2. A device for burning fuel, comprising a housing with a central fuel supply pipe, a tangential air supply pipe and an outlet cylindrical nozzle device, characterized in that, in order to improve the quality of combustion, an additional shell mounted around the fuel supply pipe installed in the area of the air supply pipe and equipped with an impeller and a shaft placed along the axis of the housing in the area of the nozzle apparatus, in which an additional guide is installed with an inclination a blade rigidly bonded to said shaft.
