<p>A plasmatron for heating a gas, more specifically air, located in a heating space, includes a nozzle having a nozzle wall and a nozzle opening located in the nozzle wall, whereby a ratio of a maximum diameter of a cross-section of the nozzle opening with respect to a first length of the nozzle opening is higher than 2. The plasmatron includes a cathode, a space located between the cathode and the nozzle wall, and a channel for guiding water or a water-containing liquid in the direction of the space. A heating device further includes a connection for connecting the plasmatron to a water supply system.</p> |
