Abstract
The present invention relates to one or more heat exchangers in communication with a combustion zone, each heat exchanger containing a matrix of heat exchange media, the matrix having a plurality of defined parallel or substantially parallel flow passages, the matrix being angled slightly above horizontal in the direction towards the combustion zone. The present invention is also directed to a regenerative thermal oxidizer including the one or more heat exchangers containing the angled matrix.
Claims18
A regenerative oxidizer, comprising:
- at least one heat exchange column in communication with a combustion zone, said heat exchange column having a first end and a second end spaced from said first end, said second end being nearer to said combustion zone than said first end;
- and
- a matrix of heat exchange media in said heat exchange column, said matrix being arranged in said heat exchange column such that at least a portion of the matrix nearer said second end is inclined with respect to horizontal, said matrix having a plurality of gas flow passages arranged between said first end and said second end of said heat exchange column such that the flow of gas through said passages is substantially horizontal, said matrix having a plurality of heat exchange elements arranged in a direction perpendicular to the direction of gas flow through said gas flow passages.
A regenerative thermal oxidizer for oxidizing contaminants in a gas, comprising:
- a combustion zone;
- a first heat exchange bed in communication with said combustion zone and having a first end and a second end, said second end being closer to said combustion zone than said first end;
- a second heat exchange bed in communication with said combustion zone and having a first end and a second end, said second end being closer to said combustion zone than said first end;
- heat exchange media supported in each of said first and second heat exchange beds such that at least a portion of said heat exchange media closer to said second ends of said first and second heat exchange columns is at an angle of about 1 to 10° relative to horizontal, said media having a plurality of gas flow passage arranged between said first end and said second end of said heat exchange column such that the flow of gas through said passage is substantially horizontal;
- said media comprising a matrix having a plurality of heat exchange elements arranged in a direction perpendicular to the direction of gas flow through said gas flow passages.
A regenerative oxidizer, comprising:
- at least one heat exchange column in communication with a combustion zone, said heat exchange column having a first end and a second end spaced from said first end, said second end being nearer to said combustion zone than said first end;
- and
- a matrix of heat exchange media in said heat exchange column, said matrix being arranged in said heat exchange column such that at least a portion of the matrix nearer said second end is inclined with respect to horizontal, said matrix having a plurality of gas flow passages arranged between said first end and said second end of said heat exchange column such that the flow of gas through said passages is substantially horizontal, said matrix nearer said second end being inclined at an angle greater than the angle at which the matrix nearer said first end is inclined.
