sound of the burn off may be quite loud. If the flare is used near residential areas, this type of flaring is not preferable.
A combustor, on the other hand, serves the same purpose, but is performed in a near-closed shell. Where flares are made to be quite tall in order to raise the flame far above the ground (32 to 320ft above ground), combustors may be quite low to the ground (10 to 16 ft on average). Combustors are also designed to burn gases with high efficiency and very low emissions.
Both flares and combustors are in high demand by the Oil & Gas Industry in order to satisfy the requirements of the EPA’s 40 CFR Part 60 Subpart OOOO (also known as Quad O) and other regulations like Canada’s Directive 017.
Flares and combustors are used throughout the Oil & Gas Industry, whether on-shore or off-shore, in order to burn off excess gases or during upset conditions in the process. Monitoring the fuel to these flares at the inlet is part of meeting these regulatory requirements as gases flared must be reported. A flowmeter used in this application must be ready to read accurately at both very low flow rates and at high velocity for upset conditions. The thermal mass flowmeters from Fox Thermal are uniquely suited for these applications. Ask our Application Specialists for more information.
