4 <br /> SECTION II <br /> CATALYTIC/THERMAL VTM <br /> THERM-CAI SPECIFICATIONS <br /> IOne (1) GIobal Model 1 VTM Therm-Cat, shall process up to 125 SCFM of VOC laden air, <br /> providing 98+% destruction efficiency of the VOCs listed in Section I <br /> IDuring system operation, VOC laden air shall be drawn by the system blower (B) from the upstream <br /> remediation process and diluted to the appropriate air mixture using a manual valve (A) The blower <br /> (B) shall discharge the contaminated air past the flame arrestor(C) and into the cold side of the primary <br /> heat exchanger (G) where it shall be preheated prior to the gas burner Within the burner/reactor <br /> section (D&E) the contaminated air shall be raised to catalyzing or incinerator temperature by the <br />' flame front prior to entering the catalyst module (F) or reactor chamber (E) When the vapor laden air <br /> passes through the catalyst an exothermic reaction shall take place The hot purified air shall then pass <br /> through the hot side of the heat exchanger (G) where it shall preheat the incoming air The vapor free <br /> air shall finally be exhausted (H) to atmosphere <br /> A] DILUTION AIR CONTROL: <br /> A manual damper shall be supplied to dilute the inlet air stream during high VOC <br /> concentrations An automatic dilution air system is available as an option <br /> B] SYSTEM BLOWER. <br /> The system blower shall be of the regenerative type The Rotron DR-6 shall be powered by a <br /> 5 HP, 230V or 460V / 60Hz/3PH TEFC motor The system blower shall serve the purpose of <br /> providing a vacuum of 4" H G at the rated flow <br /> C] FLAME ARRESTOR. <br /> A met:1 grid type flame arrestor shall be supplied The flame arrestor shall be placed between <br /> the fan discharge and neat exchanger inlet <br /> D] BURNER/GAS TRAIN- <br /> The gas burner package shall be pre-piped, pre-wired and shall have a maximum firing rate of <br /> 9nn nno RTT T/hniar TI,P hiirner shall hP ranahlP of natriral aac nr nrnnan�nn�+ratinn <br /> I The burner shall be mounted to allow the flame to fire in the direction of airflow Uniform <br /> temperature entering the catalyst shall be achieved by proper air distribution over the burner and <br /> mixing downstream. of the burner via a flame diffuser The burner shall be selected to bring the <br /> reactor up to catalyst ready temperature with ambient air dunng start-up The burner shall have <br /> the capacity to maintain operating temperatures during VOC free, full air flow conditions <br /> I CONDOR EARTH TECHNOLOGIES <br /> GBL-8585 <br />
