MULTIFUNCTIONAL BURNER (VERSIONS) Russian patent published in 2013 - IPC F23D17/00 

FIELD: power industry.

SUBSTANCE: multifunctional burner includes a heat-resistant housing, vertical slot-type air outlet openings divided with a partition wall, with parallel conditional vertical symmetry planes, external and internal side vertical walls, ceiling and bottom coverings, which are installed in the centre of the housing, main gas outlet round nozzles installed in a circumferential direction of the housing along external vertical wall or inside the air outlet opening in a vertical row with a uniform pitch with longitudinal axes arranged in the conditional vertical plane at an angle to conditional vertical symmetry plane of the air outlet opening, additional gas outlet round nozzles with longitudinal axes arranged in conditional vertical plane at an angle to conditional vertical symmetry plane of the dust-air outlet opening, which are installed in a circumferential direction of the housing along external vertical wall of the dust-air outlet opening in a vertical row with a uniform pitch, as well as single-nozzle suspension atomisers with longitudinal axes. According to the first version, main gas outlet round nozzles are installed in a circumferential direction of the housing along external vertical wall, and according to the second version - inside the air outlet opening in the vertical row with uniform pitch. When designing a multifunctional burner, both as per the first, and the second version, atomisers are installed in a circumferential direction of the housing in a common vertical row in turn with additional gas outlet nozzles with a common uniform space, and their longitudinal axes are oriented along the conditional plane of arrangement of longitudinal axes of additional gas outlet nozzles.

EFFECT: invention allows increasing the fuel burnout degree at combustion of coal-water suspension.
