Abstract
An air curtain generator is provided in which an arrangement is incorporated for purposes of heating input air so that an air curtain is generated which is formed with heated air. The air is heated by igniting a mixture of combustible gas and air with the combustion products thereof being distributed through an elongated conduit provided with openings through which the combustion products are discharged. Intake air flows over the conduit into an air curtain generator which causes the thusly heated air to be distributed along a rectilinear path to form an air curtain.
