1 c )- _ <br /> INDUSTRIES, INC. <br /> I <br /> THE <br /> 1 FIRECA T 250 DIRECT FIRED <br /> THERMAL OXIDIZER <br /> WITH CAT MODULE <br />' The FIRECA7 250 is a new thermal oxidizer on the market and utilizes some <br /> unique features to process VOC's A list of features and their functions are <br />' 1 VOC DILUTION CONTROL - A PID Controiler 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 91/o destruction rate is 60% LEL or 8280 ppmv The LEL <br /> level is monitored by a MSA Combustab€es 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 %vill close off the wells and open a purge valve <br /> 2 OXYGEN LEVEL MONITORING - A PiD Controller monitors 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 /> 17% + ) If the oxygen level drops below 17o/J the wells will be closed and <br /> a purge valve will open <br /> 3 TEMPERATURE CONTROL - A FID 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 /> catalvtic module and maintains a 650 Degree temperature Exhrust <br /> temperature will range from 1150 - 1250 Degrees <br /> 4. HIGH LIMIT CONTROLLER - A FID 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 setpoint. <br /> 3830 E.
