DEVICE FOR HEATING VINEYARDS AND OTHER PLANTATIONS IN THE GROUND

摘要

The device has a gas or oil burner (1), the flame (5) of which heats a tube-like combustion chamber (39) to such an extent that the radiating surfaces (49) of the combustion chamber (39) which are directed towards the crops (53) to be protected reach a glowing heat of between 500 and 900 DEG C and emit targeted infrared rays in the wave range from 1 to 5 mu m. The direction of these rays is determined and delimited by reflectors (40), while the intensity and duration of the rays is controlled by pneumatic or hydraulic means, which in turn can be controlled by the excess pressure existing in the energy distribution system.
