Abstract of the Disclosure The invention provides a weed exterminator in which a hot air output flow is generated by an electrically heated blower and the combustion of a fuel such as lignite, char- coal or pit coal. The device for generating the hot air flow is composed of a fuel supply container and a hot air passage joining one another in a combustion chamber provided with an exhaust port for the escape of the hot air flow. At its juncture with the combustion chamber, the fuel supply con- tainer is provided with a fuel retention device acting to retain the fuel in such a manner that a portion of the fuel projects into the combustion chamber and into the hot air flow generated by the electrically heated blower. The hot air passage is connected to the blower in such a manner that the hot sir flow impinges on the fuel, whereby the latter is ignited, as a result of which a hot a flow is generated at a substantially higher temperature.
