IJJI <br /> INDUSTRIES, INC. <br /> THE <br /> FIRECAT 250 DIRECT <br /> FIRED <br /> ' THERMAL OXIDIZER <br /> WITH CAT MODULE <br /> ' The FIRECAT 250 is a new thermalxF <br /> o dizer on the market and utilizes some <br /> ' unique features to process VOCs. A Inst of features and their functions are. <br /> 1 ' VOC DILUTION CONTROL - A PID Controller modulates a mechanical <br />' valve to control the Influent vapors at a pre-set level ACCURACY (+ or - <br /> 1 % of the lower explosive level). The maximum LEL percentage the oxidizer <br /> can process at a 99 9% destruction rate is 60% LEL or 8280 ppmv The LEL <br />' level Is monitored by a MSA Combustables Catalytic Bead Sensor and <br /> Transmitter which supplies a signal to the PID Controller If the LEL% rises <br /> above a pre-set level it will close off the wells and open a purge valve <br /> y 2: OXYGEN LEVEL MONITORING - A PID Controller monitors <br /> the oxygen <br /> level to insure the oxygen level is sufficient to combust all vapors and <br /> supplemental fuel that: is Introduced to the oxidizer. The controller receives a <br /> signal from a MSA oxygen sensor and transmitter, Oxygen Level Required <br />' <br /> 17% +). if the oxygen level drops below 17% the wells will be closed and <br /> a purge valve will open. <br />' 3:TEMPERATURE CONTROL - A PID Controller modulates a mechanical <br /> valve on the supplemental fuel line to control the oxidizer temperature at <br /> 1400 Degree Fahrenheit with an accuracy of (+ or - 5 degrees). The <br />' controller receives a signal from a type K thermocouple in the oxidizer stack <br /> VOC's will not be Introduced until the oxidizer has reached the pre-set 1400 <br /> Degree temperature When the system Is converted to "CATALYTIC" the <br /> Temperature Controller receives a signal from the influent side of the <br /> catalytic module and maintains a 650 Degree temperature Exhaust <br /> temperature will range from 1150 - 1250 Degrees. <br /> 4: HIGH LIMIT CONTROLLER - APED Controller monitors the temperature of <br /> the oxidizer to insure that It stays within the safe operating perameters of <br /> the system If the temperature rises above a pre-set level the oxidizer shuts <br /> Off the system until it is manually reset When the system Is converted to <br /> "CATALYTIC" the High Limit controller has a lower setpolnt. <br /> 353(} E.
