IPC: F23D11/02
Filed: 1979-10-18
Abstract: PURPOSE: To obtain a burner enabling combustion in blue cone with a greater combustion volume by employing a combustion system combining a spraying nozzle and a vaporizing chamber.  
     CONSTITUTION: When the vaporizer reaches a given temperature with a heater 5, a combustion blower 3 is driven to feed air into a mixing chamber 7 through an air feeding port 11. At the same time, a fuel feed pump 2 is actuated to supply a pressurized liquid fuel to a spraying nozzle 1 to start spraying.
