Abstract

A superheating burner for supplying an activating agent to an activator used in the production of activated carbon includes a conduit 8 for feeding fuel and air to a chamber 4 and, extending through at least the part of the conduit 8 nearest the chamber 4 a straight pipe 10 for the medium, such as steam to be superheated, the pipe 10 terminating in the chamber 4 spaced from the end of the conduit 8. Optionally, the pipe 10 is axially adjustable and has a plurality of outlet orifices 11. <IMAGE>

Description

" one

The invention relates to burner designs for burning a mixture of liquid and gaseous fuels and can be used in the production of activated carbon.

The purpose of the invention is to simplify the operation and intensify the process by adjusting the flame front.

The drawing shows the burner, a longitudinal section.

The preheating burner consists of a pipe} for feeding the mixture of fuel and air into the overheating chamber, pipe 2 for supplying secondary air located coaxially outside the first pipe 1, and tube 3 for supplying the heated medium.

The tube 3 for supplying the heated medium is installed coaxially in the center of the pipeline 1 for feeding the mixture with the possibility of moving along its

58333

axis and is made with holes 4 located at its output end in the overheating chamber.

The burner works as follows.

The secondary air enters the pipeline 2 of the burner, the fuel and the primary air are fed through the pipeline 1, and the superheated liquid

 O or gas is fed through the tube 3 of adjustable length. During ignition of the burner, the outlet end of the tube 3 must be located at a sufficient distance from the flame front,

15 to overheat environment when

the flow through the holes 4 did not disrupt the burning process. After ignition of the burner, the outlet end of the tube 3 is brought closer to the front.

20 flame, resulting in efficient mixing of combustible gases with superheated medium.

Claims (1)

A HEATING BURNER containing a pipeline for supplying a mixture of fuel and air to the overheating chamber, a secondary air supply pipe located coaxially outside the first pipe, and a pipe for supplying a superheated medium, characterized in that, in order to simplify operation and intensify the process by controlling the flame front, the overheated medium supply pipe is installed coaxially in the center of the mixture supply pipe with the possibility of movement along its axis and is made with holes located at the outlets one end of it in the overheating chamber. > SM
