Inspect unit immediately when it is received to determine if any damage has occurred during shipment. RDI is not responsible for any damages if unit was shipped via a third- party shipping company. Check for any visible damage to the unit. If any damage is found, the consignee should sign the Bill of Lading indicating said found damage and immediately file a claim for damage with the transportation company.
860 FLARE SKID BASIC DESCRIPTION The 860 Flare Skid is a factory assembled hydraulic flare skid designed to burn off excess gas for natural gas operations. These units are stand-alone units that are designed for ease of use and relocation. DO NOT alter these units in any way. If you have any questions after reading this manual, contact the manufacturer.

860 FLARE SKID SOLAR PANEL CONNECTION THE FOLLOWING STEPS FOR ACL SYSTEM MUST BE COMPLETED ONLY AFTER THE JUMPER CABLES HAVE BEEN REMOVED FROM THE HYDRAULIC PUMP. 1. Remove the solar panel from the storage box. 2. Adjust solar panel to 45 degrees. (Center mark on bracket.) Face panel due south.
860 FLARE SKID TROUBLESHOOTING GUIDE In the event of an ignitor malfunction while gas is being released into the tube, shut off gas supply and wait 5 minutes for any trapped gas to purge. Gas build-up can cause damage to the unit, injury or death if it is ignited. Once the purge is complete, turn on gas and go through the basic operational procedures outlined in “Standard Operating...
860 FLARE SKID MAINTENANCE REQUIREMENTS NOTICE: The flare skid and all components should be completely expected prior to each use. Skid should be inspected for cracks, damage and wear and tear prior to being put into service. DISCONNECT all electrical and gas supply sources prior to servicing unit. Failure to do so may result in personal injury or death from electrical shock.

860 FLARE SKID (ii) Steam-assisted and non-assisted flares designed for and operated with an exit velocity, as determined by the methods specified in paragraph (f)(4) equal to or greater than 18.3 m/sec (60 ft/sec) but less than 122 m/sec (400 ft/sec) are allowed if the net heating value of the gas being combusted is greater than 37.3 MJ/scm (1000 btu/scf).

860 FLARE SKID (f)(4) The actual exit velocity of a flare shall be determined by dividing the volumetric flow rate (in units of standard temperature and pressure) as determined by Reference Methods 2, 2A, 2C or 2D as appropriate; by the unobstructed (free) cross sectional area of the flare tip.

860 FLARE SKID Based on values given using the following textbook: Paraphrasing from the “John Zink Hamworthy Combustion Handbook, 2 Edition: Volume 3, Section 11.5 Flare Combustion Products” 11.5.1 Reaction Efficiency The terms combustion efficiency and destruction efficiency have frequently and mistakenly been considered synonymous.

BTU’s of the gas being flared, they should be able to increase the exit velocity and maintain good efficiency (use the equation above). Based on these EPA guidelines / regulations, RDI 640/660 Flares are 98% combustion efficient within the range: 1.017 MMSFCD – 6.786 MMSFCD Flow rates above or below these values are beyond EPA regulations and may not be at an adequate combustion efficiency.
CFR 60.18 Compliance Letter Calculated Assuming the Net Heat Value (V Assuming BTU/SCF are above 1000, RDI Flare Trailers can be assumed by the EPA to achieve 98% combustion within the following flow rates: When it comes down to it, all we can do is go with 60.18 to assure a 98% combustion efficiency.
