Abstract
The invention provides a method and apparatus for minimizing heat degradation of a vapor decontaminant in a vaporizer by selectively operating a plurality of vaporizer heaters to provide a decreasing heat gradient through the vaporizer. A method and apparatus are also provided for selectively operating a plurality of preheaters, in series, for preheating a carrier gas entering a vaporizer in a flow-through decontamination system, and for maintaining a predetermined carrier gas temperature. A further method and apparatus are provided for fine-tuning chamber pressure in a high flow rate closed-loop flow-through vapor phase decontamination system.
