  • Patent number: 4504215
    Abstract: In the construction of a liquid fuel burner in which liquid fuel is subjected to two-staged combustion, active and passive expedients are preferably combined for complete burning of the liquid fuel. The active expedient employs specified edge construction of a fuel scatter ring for production of ideally atomized fuel whereas the passive expedient employs a barrier construction arranged at the open front end of a combination cylinder for effective prevention of fuel drop causable of incomplete fuel burning.
