Abstract: The smokeless liquid two-phase burner system of the present invention relates to a method and apparatus for burning a wide variety of flammable liquids using an integrated burner system. The system has both a primary injection path and an alternate injection path for the liquid fuel to be burned, as well as a main air pump or blower. The present invention also provides a method and apparatus for selectably injecting a secondary stream of a gas or vapor or volatile liquid into a flare system for the purpose of enhancing combustion.

Abstract: An embodiment of the invention involves a method for servicing a choke valve that includes disconnecting a choke actuator and at least one internal valve component engaged therewith from the choke valve body of the choke valve and moving the same in a generally linear path away from the choke valve body along the axis of the choke valve body.

Abstract: The present invention relates to an apparatus for use in field servicing a choke valve system. The apparatus is used for lifting, manipulating, and handling the heavy components of hydraulic choke valves. The apparatus includes an elongated track, a choke valve support structure, a trolley that selectably reciprocates along a length of the trolley, and an attachment mechanism for attaching a choke actuator to the trolley.

Abstract: The present invention relates to a mechanism for preventing damage to the actuator of a hydraulic choke valve in the event of excessive backpressure on the outlet of the choke. The backpressure relief device is applicable to a choke valve which meters flow from a high pressure annular region around the axially reciprocable choke throttling member into a low pressure exit channel coaxial with the throttling member. In particular, a shearable means is used to connect the reciprocable control shank of the actuator to the throttling valve member of the choke valve. In the event of excessive pressure on the exit channel of the choke valve, the shearable means will shear, thereby fully opening the valve and permitting the excessive pressure to escape. The shearable means is readily replaced so that the valve easily can be put back into operating condition.
