Title: Liquid fuel combustion apparatus
Inventor: KAWASAKI YOSHITAKA
IPC: F23D5/02
Filed: 1978-04-20
Abstract: PURPOSE: In a suction-vaporization type of liquid fuel combustion apparatus, to increase a specific fuel consumption upon stopping of fuel supply followed by putting out a flame by providing an air stream toward the vaporization portion, sesulting in reduction in the extinguishing time.  
     CONSTITUTION: During normal combustion, the air stream supplied through  vaporizing air inlets 4a conveys the vaporized fuel gas stream from the upper  vaporization portion 3 of a suction portion 2 of which lower portion is immersed in an oil supply tube 7, to a combustion chamber 5. However, upon a stop of fuel supply based on closing a fuel shut down valve 8, a specific fuel vavorization decreases and a mixing ratio of the air within a vaporization chamber 4 enters an inflammable range, resulting in an internal fire of the chamber 4. As the fuel-air mixture become a inflammable state at the sites where the air flowing through the inlets collide against the vaporization portion 3 to produce a flame, the specific fuel consumption is increased, resulting in reduction of the extinguishing time.
