Abrégé

A device (10) is described for preventing damage to crops by means of heated ambient air, the device comprising gas reservoirs (120) a gas burner (110), a centrifugal fan (130) and a heating device (140). The heating device (140) branches off a part of the flow of the heated ambient air to an outlet (134) of the centrifugal fan (130) and allows it to flow to the bottom side (122) of the at least one gas reservoir (120).

Abrégé

A method and apparatus are described for the control of vegetation (10) by means of a heated gas (20) that is generated in a burner (30) and which via an outflow opening (42) of an outlet channel (40) is passed to the vegetation (10) to be controlled. A fan (50) is arranged between the burner (30) and the outlet 10 channel (40) in order for the fan (50), while in operation, to suck in the heated gas (20) from the burner (30) and discharge it to the outlet channel (40) and thereby exhibiting a flame-retarding action.

Abrégé

Gas burner (1) consisting of a burner pipe (2), in which gas is supplied and which is provided with a row of linearly arranged perforations (3) that allow the gas through to a burner chamber (4), and with an ignition mechanism (5) to ignite the gas electrically, characterised in that the burner pipe (2) is provided on the inside with a gas distribution pipe (6) in order to evenly distribute the gas supply over the entire row of perforations (3), and that the burner chamber (4) is surrounded by a premounted air chamber (7), which is connected to the burner chamber (4) by means of air slots (9), whereby the air slots are oblique with respect to the longitudinal axis of the burner pipe (2) at an angle between 10° and 80°, and whereby the air supply through the air slots (9) is controlled by a device that blows in or draws in air through the premounted air chamber (7).
