<p>Apparatus for controlling and/or killing weeds, unwanted growth or the like, said apparatus comprising a reservoir 30 for a liquid such as water, at least one heating element 25 for heating of the liquid, and steam outlet means. The apparatus comprises a boiler 20 in which the at least one heating element is incorporated. The boiler is placed in a lower part (3) of the apparatus, and the reservoir for liquid is connected to the boiler. By this apparatus, water is heated to steam in a boiler near the ground, whereby the steam has to be transported for only a small distance. Hence, the temperature drop in the steam will be insignificant. As the heating of the liquid takes place in the lower part (3) of the apparatus, there will be no discomfort to the user due to heated parts or heated liquid being positioned near the body of the user. Further, as heating of the liquid takes place in a separate boiler, only a fraction of the liquid contained in the apparatus has to be heated before the apparatus will be ready for use, and no energy will be wasted to heat a relatively large quantity of liquid which may not even be used for treating weeds. The invention also relates to a method for producing steam for controlling and/or killing weeds, unwanted growth or the like. <IMAGE></p> |
