G <br />11 <br />ABUTEC- and <br />Berner <br />To�Advnnoiceogl— CONFIDENTIAL AND PROPRIETARY <br />Emissions (Guaranteed by ABUTEC LLQ <br />Destruction Efficiency: 99.9% DRE, In Full Operation Range <br />NOX Emissions: Less than 0.041 lbs/mmBTU (<34 ppm at 3% 02) <br />CO Emissions: Less than 0.20 lbs/mmBTU (corrected to 3% 02); <br />NMOC Emissions Less than 20 ppmv DSCFM at 3% 02 (as hexane) <br />III. Narrative Solutions (HTF-Hi h; Temperature Flare) <br />General Information Regarding Our Scope of Supply: <br />All installations according to our technical data sheet are delivered fully mounted, functionally tested without <br />gas), and ready for site installation and operation. ABUTEC will include a Factory Acceptance Test (FAT) <br />Report upon completion of the FAT. <br />General Process Engineering Data: <br />The flare will have an AUTO/MANUAL/OFF setting on the control panel. In AUTO mode, the flare will be <br />in standby awaiting sufficient LFG pressure (as sensed by the pressure transmitter — field settable). Once the <br />"Flare Start" pressure is reached, the pilot solenoid(s) will open and the spark igniter will begin sparking. The <br />UV sensor (already searching for a flame) will indicate when the pilot is ignited. Once the UV Sensor detects <br />that the pilot flame is ignited, the LFG Pneumatic Valve (supplied by others) will slowly open and the main <br />burner will ignite. The louvers will automatically adjust (via a PID loop) to maintain a preset stack <br />temperature (i.e. 1800 deg F) based on minimum consumption of LFG. When the main process (i.e. 99.9% <br />Air) stream is ready to burn, an external signal to our Control Panel will signal "ready" and then open the <br />Pneumatic Valve (supplied by others) on the Process Line. The louvers will continue controlling temperature <br />to the preset value (i.e. 1800 deg F). We have several safety shutdown's built into the system that will be <br />discussed and agreed upon during detailed engineering of the system. If a safety shutdown parameter is <br />reached, the Main Control Valves (Air & LFG) will close within 3 seconds. <br />Technical Description of BIOGAS COMBUSTION UNIT (HTF): <br />Page 5 of 14 Documents/Quotations/2010.203.002AM <br />
