Abstract
Integrated web dryer (100) and regenerative heat exchanger (H1, H2), as well as a method of drying a web of material using the same. The apparatus and method of the present invention provides for the heating of air and the converting of VOCs to harmless gases in a fully integrated manner via the inclusion of a regenerative combustion device as an integral element of the drying apparatus.
Claims (8)
1. A regenerative thermal oxidizer for processing a gas, comprising:
a combustion zone;
a first heat exchange bed containing heat exchange media and in communication with said combustion zone;
a second heat exchange bed containing heat exchange media and in communication with said combustion zone;
at least one valve for alternating the flow of said gas between said first and second heat exchange beds; and a bypass valve in communication with said combustion zone for regulating the amount of gas in said combustion zone that bypasses one of said first and second heat exchange column, said bypass valve comprising a damper cast of a nickel-based superalloy.
a combustion zone;
a first heat exchange bed containing heat exchange media and in communication with said combustion zone;
a second heat exchange bed containing heat exchange media and in communication with said combustion zone;
at least one valve for alternating the flow of said gas between said first and second heat exchange beds; and a bypass valve in communication with said combustion zone for regulating the amount of gas in said combustion zone that bypasses one of said first and second heat exchange column, said bypass valve comprising a damper cast of a nickel-based superalloy.
2. The regenerative thermal oxidizer of claim 1, wherein said damper further comprises chromium.
3. The regenerative thermal oxidizer of claim 2, wherein said nickel content is from 32-45% and said chromium content is from 23 to 27%.
4. The regenerative thermal oxidizer of claim 1, further comprising a web dryer integrated with said oxidizer, and wherein said valve in communication with said combustion zone diverts hot air in said combustion zone to said web dryer.
5. The regenerative thermal oxidizer of claim 4, wherein said valve in communication with said combustion zone is regulated based upon the temperature in said dryer.
6. The regenerative thermal oxidizer of claim 4, wherein said valve in communication with said combustion zone is also in communication with a mixing chamber in said web dryer to supply hot combustion zone air to said mixing chamber.
7. The regenerative thermal oxidizer of claim 6, wherein said mixing chamber receives make-up air and mixes said make-up air with said hot combustion zone air to lower the temperature of said hot combustion zone air.
8. The regenerative thermal oxidizer of claim 1, wherein said damper comprises a blade and a compression ring, and wherein said compression ring comprises a cobalt-based superalloy.
