The present invention is directed to an apparatus for directing steam, hot water or hot water vapor and hot air onto a target area, the apparatus comprising a water container and a fuel container connected and supplying water and fuel to an applicator wand with an applicator head which generates steam and heat for application adjacent to the target area of application to the unwanted vegetation. Steam is generated immediately adjacent to the target area within the applicator head and combined with surplus heat from the steam generation process to produce heated steam and water vapor for application to the target area. In a preferred embodiment of the invention, the applicator wand is hand held, the applicator head having an inlet, an outlet and a body therebetween, the water and fuel being supplied to a steam generator and burner within the body of the applicator head which generates steam and hot air adjacent to the target area for application through the outlet to the target area.
An apparatus for directing at least one of steam, hot water and hot water vapor along with air heated by a burner onto a target area, the apparatus comprising a water container and a fuel container connected and supplying water and fuel to a boiler and the burner within an applicator head attached to a holding means, the applicator head comprising an inlet, an outlet, and a body therebetween, the boiler and burner being located adjacent the outlet and generating a blast of at least one of steam, hot water and hot water vapor along with heated air from the burner adjacent to the outlet for application through the outlet to a target area a first control for controlling the flow of water comprising an ON position and an OFF position and a second control for controlling the flow of fuel comprising a STAND BY position in addition to an ON and an OFF position the STAND BY position permitting sufficient flow of fuel to maintain a low flame in the burner, the controls controlling the flow of water and fuel so that the blast of at least one of steam, hot water and hot water vapor along with heated air is only generated as needed.
An apparatus fat producing a blast of heated air and at least one of steam, superheated steam, hot water and hot water vapour for application to a target area, said apparatus comprising:
An apparatus for generating at least one of steam, hot water and hot water vapor along with air heated by a burner for application to unwanted vegetation, the apparatus comprising:
