摘要：
A burner arrangement with concentrically arranged annular channels (2, 3, 9, 13) for the supply of various fuels (B, C, E, F) and an outer conically tapering air supply annular channel system (4), in which a gaseous medium (B) or a liquid medium (C) fed through a plurality of outlet nozzles (11, 14) can be mixed in finely divided form with a current of air (A) flowing in the air supply annular channel system (4), and in which in addition another annular channel (16) opens into the air supply annular channel system (4) on the inlet side above the outlet nozzles (11, 14). The other annular channel (16) is used for the supply of a combustion gas with a low specific calorific value, e.g. coal gas, while otherwise the burner arrangement can be operated in accordance with the state of the art as a premixing burner with gas and/or oil. The emission of NOX to the environment can be minimised with all fuels and types of combustion used.
