TWO-FLUID JETTING DEVICE OF ATOMIZING TYPE BURNING EQUIPMENT

摘要

PURPOSE:To make the atomization of fuel and fire flame excellent over a wide range of the flow amount by a method wherein fluid fuel is spouted into an air flow revolving chamber for atomization and the fuel is atomized by an air flow for atomization spouted from the opening of an orifice while revolving around a fuel spouting needle. CONSTITUTION:At a burning air flow revolving chamber 2 a burning air flow is introduced around the axial center of the chamber and liquid fuel such as gas oil and kerosene or gasoline is sprayed into the center of a revolv-air flow at the chamber 2 from a two-fluid jetting device 11. When the spouting end of a fuel spouting needle is placed at the contracted flow part of an air flow for atomization spouted from the opening of an orifice 19 in projecting state from the face of the orifice 19, fuel spouted from the end of the needle 15 is smoothly mixed with the air flow for atomization spouted from the opening of the orifice 19 and transferred to stabilize the atomization of fuel and also make the atomization excellent. Further, the atomization of fuel is prevented from carbonization caused by its adhesion on the orifice 19.
