Title: Oil-feeding tank
Inventor: NAGAO MASATOSHI
IPC: F23K5/00
Filed: 1979-02-22
Abstract: PURPOSE: To prevent water from pouring into a warmed air type-heating device, by a device wherein a central tube of a mouth ring of an oil-feeding tank is lengthened and an oil inlet port is located at an upper portion thereof.  
     CONSTITUTION: A lighting glass 5 made watertight by the use of a packing and screw, is located at an upper portion of a slope at the bottom of a tank 3. There is no oil inlet port 8 at the bottom of a tube 7. This causes water mixed in an oil- feeding tank to be naturally seperated at the bottom of the tank and permits water to be prevented from pouring into a heating device proper until water comes up to the oil inlet port 8. A trouble on a buraing interruption can thus be prevented even if the mixture of water is not noticed for a period of a good long time.
