GAS BURNER Russian patent published in 1994 - IPC

FIELD: thermal power engineering. SUBSTANCE: stabilizers 5 has axial canals 9 with inlet converging areas 10 and outlet diffusing areas 11, conjugated with each other by cylindrical areas 12. Confusing areas 10 are made in the form of truncated cones with the angle of opening equalled to 44 - 46 deg. Front butts 6 of stabilizers 5 are made as truncated cones with the angle of opening equaled to 44 -46 deg and smaller bases of which are turned to branch pipes 4. Peripheral holes 8 are located at the angle of 29 -31 deg to axis of stabilizers 5 along the stream movement way and total area of their passing section makes 38 - 44 % of area of passing section of cylindrical area 12. Diameters of outlet branch pipe 2 of air feeding body 1 and gas pipe 3 are in ratio of 2.5 :1. Difference of lengths of gas outlet branch pipe 4 and air outlet branch pipe 2 equals to two diameters of gas branch pipe 4. EFFECT: gas burner is effective in draying and heating of crumble mixtures. 2 dwg
