Abstract: A liquid seal mating system to accommodate thermal expansion during elevated-temperature operation, including a collar, sized and shaped to receive a discharge end of a gas-delivery conduit and a fence that surrounds the collar and is attached thereto, wherein when installed, the collar accommodates thermal expansion of the gas-delivery conduit along a longitudinal axis of the gas-delivery conduit and limits movement of the gas-delivery conduit perpendicular to the longitudinal axis. A method for suppressing bulk fluid motion in an elevated-temperature liquid seal, including attaching a mount to an outer shell of a liquid seal and receiving, within a mating collar, a discharge end of a gas-delivery conduit, the mating collar attached to the mount and being sized and shaped to accommodate thermal expansion of the gas-delivery conduit, filling the outer shell with liquid to submerge the discharge end of the gas-delivery conduit, and flowing gas through the gas-delivery conduit.

Abstract: A ground flare for treating waste gas comprises a rectangular enclosure including opposing first and second side walls and opposing first and second end walls. The first and second side walls have a greater length than the first and second end walls. At least one air opening is formed in each of the first and second side walls for receiving air. At least one burner extends horizontally through each of the at least one air opening and into the enclosure. Each burner includes a fuel port disposed inside of the enclosure for injecting the waste gas into the enclosure.

Abstract: A thermal radiation shield and combustion air controlled enclosure assembly. The assembly encloses a ground flare or flares and includes a plurality of structural supports at an obtuse angle to grade. Panels extend between the structural supports surrounding the ground flare wherein the panels are at an obtuse angle to grade.

Abstract: A flare tip for the burning and disposal of combustible waste gases including internal spin vanes is provided. By providing a plurality of internal spin vanes within the waste gas inlet of a flare tip, the efficiency of combustion of waste gas can be increased.
