Abstract

PURPOSE: To reduce generation of NOx with reduction of the quantity of primary air for combustion by providing a revolving vane within an air-fuel mixture transport tube near the downstream end thereof and also providing a nozzle consisting of a central fine particle nozzle and coarse particle nozzle surrounding the central nozzle.
CONSTITUTION: A revolving vane 16 is provided within an air-fuel mixture tube 13 near the downstream end thereof, and a nozzle consists of a central fine particle nozzle 14 and a coarse particle nozzle 17 surrounding the central nozzle. Further, an inert gas supply tube 19 may be provided to extend axially within the air-fuel mixture transport tube 13. A coarse particle revolving vane 18 is provided on the upstream side of the coarse particle nozzle 14, and an auxiliary air supply tube 15 supplying auxiliary air for combustion is provided to surround the transport tube 13. coarse particles separated by revolving forces and auxiliary air for combustion can be satisfactorily mixed to reduce the quantity of primary air for combustion, thus permitting reduction of the generation of Nox.
