Abstract (en)
A pulse combustion dryer comprising a pulse combustion burner having a pulse combustion chamber, a drying chamber and a tailpipe connected to the pulse combustion chamber and to the drying chamber. The pulse combustion dryer also comprises hydrogen and oxygen inlets for feeding hydrogen and oxygen into the pulse combustion chamber, respectively, a product feeding line for feeding the product to be dried into the drying chamber, a particle separation system to separate the dried product from water steam and a steam outlet line to evacuate the water steam. The steam outlet line is connected to a steam supply line so at least part of the water steam is directed towards the pulse combustion chamber for cooling the hot combustion gas passing to the dryer chamber. The oxygen inlet is arranged in the steam supply line to mix oxygen and water steam that passes towards the pulse combustion burner.
