STEAM MIXING DEVICE AND BURNER USING STEAM MIXING LIQUID FUEL AND STEAM MIXING LIQUID FUEL BURNING SYSTEM

摘要

A burner using a steam mixing device and the steam mixed fuel, and a burning system of the steam mixed fuel are provided to completely burn up the low-class liquid fuel by supplying the steam with the fuel to a fuel torch. A steam mixing device comprises: a body(110); a cover(120) whose one side is combined in a cover connection part(115) of the body. The body is consisting of: a venturi-tube(112) formed along a central axis of a housing(111); a fuel inlet(113) formed in the side of the housing; a steam tube connection part(114) formed in the upstream of the housing; a mixed fuel tube connection part formed in the downstream side of the housing; a cover connection part(115) formed in the downstream side outside of the housing; a fuel ejection hole(116) opened in order to be connected to the fuel inlet in the downstream side cross section of the housing; and a plurality of fuel inflow holes(117) formed in a cervical region of the venturi-tube. The cover has: a hole(121) in which the mixed fuel tube connection part penetrates through; and a fuel filling space(122) formed between intervals with a body.
