Title: Fluid diffuser
Inventor: KUMAZAWA TOSHIHARU
IPC: B05B7/04
Filed: 1983-06-09
Abstract: PURPOSE:To stabilize the spraying condition of fuel into a combustion furnace and to prevent sticking and accumulation of carbon by forming the guiding surface of a fluid diffuser into a specific shape. CONSTITUTION:The gaseous mixture composed of gas and liquid ejected from a nozzle 1 collides and reflects against and on a circular collision surface 4 and collides against the succeedingly ejected flow between an ejecting hole 1a and circular collision surface 4, thereby forming diffusing flow S1. The flow S1 is diffused stably at a wide angle alpha by the guiding effect of a divergent diffusing and guiding surface 5. The flow S1 burns in a furnace F and a part of the high temp. gas flows backward in the form of circulating flow S2 along the spherical surface of a projecting end 6 and sticks on the spherical surface, thereby removing unburned particles which are intruded into the flow S1. The intruded flow S2 is the high temp. gas contg. a flame and therefore the ignition and flame stabilization of the flow S1 are continuously and stably accomplished.
