Abstract:
A regenerative oxidizer for purifying a gas, comprising:at least first and second regenerator columns, each of said columns comprising heat exchange media;gas inlet means and gas outlet means in communication with each of said regenerator columns;a combustion chamber in communication with each of said regenerator columns;means in said combustion chamber for generating heat;valve means for alternately directing said gas into the inlet means of one of said columns in a first direction and through another of said columns in a second direction;first temperature sensing means for continuously detecting temperature of said gas in a location upstream of said first column;second temperature sensing means for continuously detecting temperature of said gas in a location downstream of said second column;calculating means for calculating the difference between said temperatures detected by said first and second temperature sensing means; andadding means responsive to said calculating means for adding fuel to said gas upstream of said first column when the calculated difference is below a predetermined level.
