Himech Equipments - Flare and Burner Boom Systems for Offshore Applications

Himech Equipments is a leader in the design of oilfield equipment. Himech Equipments specialises in supplying flare and burner boom equipment.

Burner booms

Himech burner booms extend 'Sea Dragon' crude oil burners and gas flares at a set distance from an installation. This allows produced hydrocarbons to be flared safely, moving the radiated heat away from the installation.

Himech flare booms are a portable U-shaped truss assembly. The King Post attaches to the rig structure and is braced with three tieback struts. Vertical suspension cables and horizontal wind stay cables support the boom, so a rig crane is not needed for support.

Himech burner booms have been installed with three head 'Sea Dragon' burners, allowing division of the flame into three independent smaller flames. This increases the amount of air available for combustion, provided by the injection of air into the mixing chamber as well as ambient.

Flare booms - features and benefits

Available in 60ft, 90ft and 120ft lengths, the company's burner booms feature a modular design that allows for easy upgrading. The lightweight structure of the boom reduces the crane capacity requirement and simplifies the installation process.

A U-shaped configuration helps provide added security for personnel using the boom. A boom attachment point at the kingpost easily accepts the boom into U-shaped slots, thereby further cutting the installation time.

Burner boom assembly

The burner boom assembly features a wide range of components. The burner head assembly consists of three burners, cone type outer covering for burner, water spray line, set of heat resistant valves and a gas flow line.

The pilot ignition system uses LPG / propane gas for the Sea Dragon burners. The system works on 120V / 220V AC and 50Hz / 60Hz power supply.

A complete manifolding arrangement of piping and valves facilitates the selective use of any one or several of the burners at a time to achieve more efficient disposal. The U-shaped design of the boom structure supports burner heads, provides safe walkways and supports all piping for oil, gas, water and LPG / propane.

The heavy-duty king post assembly can be attached to rig structures and braced with three tieback struts. The burner boom is attached to the king post at the rotating pivot point and is supported by vertical suspension cables.
