    Abstract: PROBLEM TO BE SOLVED: To improve liquid distribution in an outer chamber of a pressure jet nozzle, and fuel distribution in a premixing burner in particular. SOLUTION: A pressure jet nozzle comprises a nozzle head 4 for communicating an outer tube 2 and an inner tube 3 at the lower stream. In the nozzle head 4 are arranged at least two separated whirl chambers or swirl chambers 9, 10, 11, 12. Each of the whirl chambers or swirl chambers 9, 10, 11, 12 is communicated respectively to a second supply passage by means of at least one swirl passage 16, a first supply passage by means of at least one whirl generating passage, and an outer chamber 18 of a nozzle body 1 by means of an outlet.

    Abstract: Under full load all the burners are operated under identical stoichiometric conditions. The burners are subdivided into at least two burner groups. In the case of operating conditions below full load, the respective burner groups are operated with different air coefficients, that is to say at different flame temperatures. The operating range of the combustion chamber is widened considerably thereby.
