The AirMach flaring system was developed to specifically address the problems associated with sonic velocity flares operating at sub-sonic flow rates. Sonic flares operating at sub-sonic exit velocities will smoke when heavier waste gas flows are present. The AirMach provides smokeless flaring performance at lower flow conditions utilizing a blower for combustion air. In this application, the AirMach operates as a traditional air-assist flare.
Steam assisted flares are flares designed to dispose of heavier molecular weight gases which have a tendency to smoke. In order to prevent smoke formation, steam is injected into the waste stream using peripheral steam rings, center stream spargers and/or inner induction tubes. Steam flares are used in applications where high pressure steam is available on site. Steam flares are typically found in downstream applications where high efficiency combustion of heavily hydrocarbons is required.
