Abstract

Disclosed is a pulsed dryer and a pulsed drying system. The dryer includes a pulse combustor fluid dynamically coupled to a drying chamber. The pulsed dryer can be any suitable type of dryer, for example a pulsed spray dryer or a pulsed fluid bed dryer. The pulse combustor can fire the dried fines or employ auxiliary fuel such as natural gas, propane, etc. The system can include a steam or heat transfer fluid thermal circuit for providing heat to the drying chamber and optionally for cooling the pulse combustor flue gases prior to flow into the drying chamber. The disclosed dryers and systems can be advantageously utilized for wet feedstock in general and in particular for drying biomass or other organic type feedstock.
