Abstract
A series of premix burners of different sizes are arranged at the inlet flow end of a combustion chamber, preferably of the form of an annular combustion chamber. The large premix burners, which are the main burners of the combustion chamber, and the small premix burners, which are the pilot burners of the combustion chamber, emerge into a front wall of the combustion chamber, these premix burners being arranged alternately relative to one another and at a constant distance apart. The main burners emerge directly into the front wall to the combustion space and the pilot burners have, downstream of their burner length, a precombustion chamber extending as far as the front wall. Both the evaporation of a liquid fuel and the burn-out of liquid or gaseous fuels in the low part-load range of the machine can be decisively improved in this precombustion chamber.
