Abstract
A heat exchanger for a regenerative thermal oxidizer is described which includes at least one heat exchange column provided with a multi-layer of packing material including at least one layer of randomly packed and specially shaped and sized particles, each particle being formed of a high temperature stable material and preferably having a cylindrical outer wall and internal reinforcing vanes extending from the cylindrical outer wall to the center of the particle, and at least one layer of structured monolithic media having a plurality of flow passages in the direction of gas flow through the column.
Claims22
A heat exchanger comprising:
- a heat exchanger column having an inlet for receiving a flow of gas, said column comprising a bed of packing material,
- said packing material being formed of a heat resistant, heat retaining material and being comprised of (a) randomly packed heat exchange media, and (b) structured media comprising one or more blocks comprising a plurality of gas flow channels therethrough arranged along an axis parallel to the flow of said gas, wherein the flow of gas through said gas flow channels is laminar.
A regenerative thermal oxidizer comprising:
- at least one heat exchange column containing heat-exchange media;
- a combustion chamber in communication with said at least one heat exchange column;
- gas inlet and outlet means in communication with said at least one heat exchange column;
- wherein said heat exchange media is formed of heat resistant, heat retaining material and comprises at least one layer consisting essentially of a plurality of particles and at least one layer consisting essentially of structured media comprising one or more blocks comprising a plurality of gas flow channels therethrough arranged along an axis parallel to the flow of said gas, wherein the flow of gas through said gas flow channels is laminar.
