Title:
OXYGEN-FUEL COMBUSTOR AND METHOD FOR INJECTING OXYGEN AND FUEL
Document Type and Number:
WIPO Patent Application WO/2018/038278
Kind Code:
A1
Abstract:
The present invention relates to an oxygen-fuel combustor and a method for injecting oxygen and fuel, in which the configuration for injecting oxygen and then method for injecting oxygen are unique, oxygen flow and fuel flow are not visible due to the high speeds thereof, a wide combustion reaction range is formed, and a high-temperature exhaust gas can be introduced and re-combusted. To this end, the oxygen-fuel combustor includes: a discharge head unit coupled to a heating furnace; a central supply unit in which, among fuel and primary oxygen, at least the fuel is supplied to the heating furnace; an oxygen supply unit in which secondary oxygen is supplied to the heating furnace; a central nozzle unit through which, among the fuel supplied from the central supply unit and the primary oxygen, at least the fuel is injected; and an oxygen nozzle unit through which the secondary oxygen supplied from the oxygen supply unit is injected. Here, the oxygen nozzle unit includes: an accommodation cone part that is recessed so as to decrease in diameter from an entrance; and an inclined injection hole part that passes through at an incline from the accommodation cone part toward an exit such that the injection direction of the fuel and injection direction of the secondary oxygen cross each other in front of the discharge head unit.
