Abstract

Burner consisting of external cylindrical casing (1), an air generator with vanes (2) and a fuel distribution tube (3), creating together a cylindrical mixing chamber (4), where behind the vanes (2) fuel distribution devices in the form of pipes with slots in lengthwise arrangement for fuel supply to the mixing chamber (4) are arranged, wherein the pipes (5) are arranged parallel with the burner axis and their length (L) equipped with the slots (6) for the fuel supply into the mixing chamber (4) is calculated according to the formula: L = k * À * D * n - 1 / n * N * tgÆ , Where D - is the diameter of the circle in which the pipes are arranged N - is the number of pipes in the circle n - is the number of slots for fuel feeding in each pipe Õ - is the angle of the air flow from the whirl vanes k - is the coefficient
