COMBINED PULVERIZED COAL BURNER COMPRISING AN INTEGRATED PILOT BURNER

摘要

The invention relates to a combined burner for gasifying pulverized fuels by means of an oxidant containing free oxygen at atmospheric or higher pressures and at temperatures ranging from 800 to 1800oC. The ignition device of the pilot burner featuring flame monitoring and the pulverized coal burner are integrated as a combined burner, while all operational ducts separately extend to the burner orifice, and the media conducted by the ducts are mixed only at the burner orifice. When the pilot burner is dismounted, the turbulence elements (14) that are mounted on the external surface thereof can be quickly and easily replaced in the oxidant supply duct (17) of the main burner, and the flame of the main burner can thus be optimally adjusted to the contour of the reaction chamber of the reactor.
