DEVICE AND METHOD FOR SPRAYING A COMBUSTIBLE LIQUID

摘要

The invention relates to devices and methods for the assisted internal spraying of a combustible liquid, wherein the combustible liquid is fed into a combustion area (100) through a passage (30) which ends in an outlet opening (50) and into which spray gas is fed via a plurality of channels (20), the passage (30) including a narrow portion (31) and a wider but relatively short pre-spray chamber (10) downstream from the narrow portion (31), the channels (20) including small-diameter end sections (21) tangentially leading into the narrow portion (31) of the passage (30) near the input opening of the chamber (10) such that the spray gas impacts the combustible liquid and imparts a helical movement to the combustible liquid.
