Abstract
An apparatus for drying a moving substrate containing a multiplicity of infrared emitters and a detection emitter and a device for supplying a mixture of air and gas to these emitters. The detection emitter contains an emitter body with a diffuser for distributing a fuel-oxygen containing gas mixture, a primary radiator having a combustion surface integrally connected to the emitter body, a first detection electrode, and a second detection electrode; each of these detection electrodes sends a signal to a control means when it senses the presence of flame-induced ionization. If the control means receives a signal from one but not both of these detection electrodes, it will continue supplying the air/gas mixture to the emitters. However, only when the control means ceases receiving a signal from both of the detection electrodes will it ceases allowing the supply of the air/gas mixture to the emitters.
