Narrative Solutions (HTF-High 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 /> Dimension* Materials of Construction:: ., <br /> Number of Burner C'i'rcles,,*, lInternal Burner Circles for Flare Stacic Enclosure Insulated Carbon Steel with <br /> Process Stream and 1' Premium High Temperature <br /> Internal Burner for Landfill Paint <br /> Gas <br /> Pur e'GasNOC Inlet 8 inch Base,':`Frame!Stand Premium Coated Carbon <br /> g <br /> Steel'—SandBlasted <br /> "'A"' uel Lime(LFG)* 2 inch <br /> Total HeightlExcluding HTF 1.3: 30f"t.
