Abstract:
An apparatus for drying a moving substrate comprised of a first infrared emitter, a second infrared emitter adjacent to said first infrared emitter, a third infrared emitter adjacent to said second infrared emitter, a detection emitter, means for supplying a mixture of gas and air to each of said first infrared emitter, said second infrared emitter, said third infrared emitter, and said detection emitter, control means, and means for igniting said mixture of gas and air supplied to said first infrared emitter, wherein:(a) said detection emitter is comprised of an emitter body comprised of a diffuser for distributing a fuel-oxygen containing gas mixture, a primary radiator having a combustion surface integrally connected to said emitter body, a first detection electrode, and a second detection electrode, wherein:1. each of said first detection electrode and said second detection electrode is operatively connected to said control means,2. each of said first detection electrode and said second detection electrode sends a signal to said control means when it senses the presence of ions,3. when said control means ceases receiving a signal from either said first detection electrode or said second detection electrode, it will not interrupt the supply of said mixture of gas and air to each of said first infrared emitter, said second infrared emitter, said third infrared emitter, and said detection emitter, and4. when said control means ceases receiving a signal from both of said first detection electrode and said second detection electrode, it will interrupt the supply of said mixture of gas and air to each of said first infrared emitter, said second infrared emitter, said third infrared emitter, and said detection emitter.
