A spiral shaped device for thermally processing a gas stream and a method of use thereof is provided. The spiral shaped device has at least one sidewall formed into a coil; at least one spiral passage, defined by the sidewall, for directing the gas stream through the device, and having an inlet and an outlet; and a matrix of heat resistant inert media disposed in at least a portion of the device. The device is particularly useful as a recuperative flameless thermal oxidizer for oxidizing organic material contained in the gas stream or as a heat exchanger...
A spiral shaped device for thermally processing a gas stream and a method of use thereof is provided. The spiral shaped device has at least one sidewall formed into a coil; at least one spiral passage, defined by the sidewall, for directing the gas stream through the device, and having an inlet and an outlet; and a matrix of heat resistant inert media disposed in at least a portion of the device. The device is particularly useful as a recuperative flameless thermal oxidizer for oxidizing organic material contained in the gas stream or as a heat exchanger. When the device is used as a flameless thermal oxidizer, the device preferably has at least two coiled sidewalls; at least two spiral passages defined by the coiled sidewalls; a chamber located proximate to the interior ends of the coiled sidewalls for directing the gas stream from the spiral inlet passage to spiral outlet passage; and a matrix of heat resistant inert media, preferably disposed in at least the chamber. When the device is used as a heat exchanger, the device preferably has two separate loops, where one loop directs a gas stream and the second loop directs a fluid stream in and out of the device to enable heat transfer therebetween. In the method of the present invention, a gas stream is directed in the device of the present invention, and is thermally processed therein. rix material and said second film is bonded to said second matrix material, whereby said first matrix material can be stripped by peeling said first film and said second matrix material can be stripped by peeling said second film. 2.
