The OFS 2000R
Developed to assure that refinery operators meet EPA MACT RSR 40 CFR 63.670 requirements for steam-assisted flare stacks.
The OFS 2000R can “see” through steam in the vapor phase, delivering accurate, quick-responding control signals which enable the operator to match the steam flow exactly to the flare output to prevent oversteaming or overaeration, and maximize combustion efficiency. OFS 2000R has a 5000/1 turndown ratio, no pressure drop, and is easily mounted on a steam line.
