Abstract

PURPOSE: To lower the flame temperature without using a specific device for reducing NOx by supplying the mixed fluid of a pressurized gas and a fluid of large latent heat to a burner nozzle to spray fuel for combustion.
CONSTITUTION: Fuel is supplied to an annular passage 13 between an inner pipe 11 and an outer pipe 12 in the main body of a burner. Water is injected from an end nozzle 10a of a water pipe 10. Pressurized vapor is conducted between the water pipe 10 and the inner wall of the inner pipe 11 to wrap the water mist sprayed from the end nozzle 10a, and sufficiently mixed in a space 16 to run the mixed fluid of pressurized vapor and water near the rear side of a burner tip 15 of the inner pipe 11. It is lowered in the temperature, increased in minute water drops, injected into a furnace through a spray passage 17, and mixed with oil fuel running through a fuel passage 14 for making oil drops. Thus, oil drops are wrapped by vapor films and water mist, and deprived of latent heat by the evaporation of the films and the mist for lowering the flame temperature and reducing NOx.
