IPC: F23L7/00
Filed: 1981-04-03
Abstract: PURPOSE:To enable to freely control the combustion temperature only by changing the quantity of water to supply and obtain a water injection burner enable to use on heavy gravity oil by a method wherein water is jetted under low pressure directly to the central part of a flame, in which the flame temperature has the highest value. CONSTITUTION:An atomizing air nozzle 12 is provided outside a fuel oil spray nozzle 11. Water is jetted to the center of combustion flame from a low pressure water injection nozzle 10. At the center of the flame, which has the highest temperature and is in the state of negative pressure, the water is gasified in an instant and causes water gas reaction with free carbon in the flame. When the excess air is decreased so as to get near to the theoretical amount of combustion air, because that water gas is reducing, nitrogen oxides are reduced and the radical reduction of nitrogen oxides in combustion gas is resulted. Accordingly, the complete combustion at the theoretical amount of combustion air becomes possible and the heat loss for excess air is eliminated, resulting in economizing fuel.
