BURNER WITH ADJUSTABLE INTRODUCTION OF AIR OR GAS Russian patent published in 2019 - IPC F23D17/00 F23D14/60 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. Burner contains a channel of primary air or gas passing along the X axis, limited by the outer wall and the concentric inner wall, and channels for the radial introduction of primary air or gas, the channel of air or gas contains a rim made with the possibility of a rotary movement and having axial protrusions forming the distributors, which interact with the channels for radial supply of primary air, located on the outer peripheral part of the inner wall, and the formation of two passes with different angles of inclination in each channel. Rim is made with the possibility of translational movement. Two passes are formed by additional expanding profiles of the distributor and channels for radial supply of primary air or gas, and the sum of the cross sections of these passes is constant in a plane perpendicular to X, regardless of the angular position of the rim.

EFFECT: invention allows for consistent and linear adjustment of the primary air or gas component.
