ABSTRACT:
A burner according to the invention comprises concentrical shells defining annular passages: a peripheral passage for a low-calorie gas; an intermediate passage for secondary gas having auxiliary shells defining an annular passage for a high-calorie gas and a central passage for an air mixture. The circle of an average diameter of said annular passage for a high-calorie gas defines in the outlet section a central zone which amounts to between 0.38 and 0.5 of the total area of the outlet section of the burner, and the outer shells of the peripheral passage and intermediate passage are provided with converging nozzles of equal minimum diameters.
