A burner adapted for use with alternative fluid fuels is provided. The burner includes a cartridge that comprises a nozzle with passage means therein. The nozzle passage means include an entrance adapted to receive a liquid fuel and a plurality of exit ports to discharge the liquid fuel in the direction of the combustion zone. An annular channel is formed around the nozzle and is adapted to supply a gaseous fuel or an atomizing agent for the liquid fuel to slot means, which tangentially communicate with each exit port so that the respective fluids passing through the exit ports and slot means intimately mix and are directed to the combustion zone. Fin means associated with the cartridge impart a swirling pattern to combustion air admitted into the furnace cavity.
