Ozone concentration analyzer and methods using same

An ozone concentration analyzer comprising:

• at least one catalytic chamber having an ozone decomposition path between an inlet portion and an outlet portion thereof, the at least one catalytic chamber receiving a flow of gas containing ozone by the inlet portion and having a plurality of catalytic pellets therein each catalytically reacting with the ozone of the flow of gas to decompose a totality of the ozone into oxygen in an exothermic reaction along the ozone decomposition path of the catalytic chamber, an inlet sensor for measuring a first temperature value at a first position along the ozone decomposition path, an outlet sensor for measuring a second temperature value at a second position along the ozone decomposition path;
• and
• an analyzer communicating with the sensors of the at least one catalytic chamber for receiving the first temperature value and the second temperature value therefrom, the analyzer evaluating the concentration of the ozone of the flow of gas based on the temperature difference between the second temperature value and the first temperature value and calibration data associating reference temperature differences to respective reference ozone concentrations for the at least one catalytic chamber;
• and
• at least one heat removing system for removing heat from the at least one catalytic chamber using the oxygen heated by the exothermic reaction as heat carrier, each of the at least one heat removing system having:
• an external thermally conducting conduit having one end connected to the outlet portion of the at least one catalytic chamber for receiving the oxygen therefrom and another end connected at a first arbitrary position of the at least one catalytic chamber;
• an internal therapy conducting conduit provided across the at least one catalytic chamber from the first arbitrary portion to a second arbitrary portion, wherein the heat removing system is adapted to remove heat from the oxygen flowing through the external thermally conducting conduit thus cooling the oxygen and adapted to absorb heat from the at least one catalytic chamber from the cooled oxygen flowing through the internal thermally conducting conduit;
• and;
• a third temperature sensor for measuring a third temperature value at the first arbitrary portion and a fourth temperature sensor for measuring a fourth temperature value at the second arbitrary portion, the analyzer further evaluating the concentration of the ozone of the flow of as based on the temperature difference between the fourth temperature value and the third temperature.
