Steamforce HC™

Zeeco’s SteamForce HC™ straight tube uses a true venturi design, significantly increasing efficiency and decreasing dependence on fuel gas and steam pressure to achieve smokeless combustion. SteamForce HC achieves smokeless flaring with dramatically less steam and no pre-mixing of air and fuel gas. Less steam saves money and reduces emissions generated from the production of steam.

SteamForce HC solves the most challenging aspects of steam flaring today: Longer Flare Tip Life - Reduces capping, decreases mechanical susceptibility to radiation, and maximizes the upward momentum of the flame even at lower flow rates. No Pre-Mixing - Complies with EPA Code of Federal Regulations, Chapter 1, Subchapter C, Part 63, Subpart CC requirements without premixing air with flare gas, meaning EPA NHVcz calculations are not negatively impacted – not true of competitor designs that use pre-mixing. Reduced Emissions - Emissions savings directly correlate to the reduced demand for steam. Lowest Cost of Operation - The SteamForce HC meets requirements and efficiency targets at lower minimum steam and purge enrichment rates than any other competitive offering.

Smokeless operation at lower flow rates.

The ZEECO® SteamForce HC is significantly less dependent upon fuel gas pressure. The development case was based on a maximum flare gas pressure of 3 psig at maximum flare gas flow with smokeless operation at 20% of maximum flow. The resulting pressure at the smokeless flare gas flow rate was a mere 0.12 psig –– versus other designs which require higher flare gas pressures of up to 5 psig to achieve smokeless operation as promised.

Revolutionary SteamForce HC Technology

The air and steam mixture leave the flare at the same elevation as the flare tip exit. Because other industry designs pre-mix the air and steam with the flare gas prior to exiting the flare tip, they are forced to operate at higher enriching rates to compensate. The SteamForce HC maximizes the amount of air entrained by a given amount of steam. With more air flow, less purge steam is required to protect the equipment during low flow scenarios.

SteamForce HC Key Design Features

• Flare gas flows through the flare gas connection into the reduced surface area head to reduce the amount of area exposed to radiation.
• A single steam supply connection simplifies control, protects against improper operation, and reduces capital costs.
• From the head, the flare gas flows into multiple nozzles depending on the amount of flare gas flow required and the desired steam consumption at the designed smokeless rate.
• Each nozzle is comprised of a small cross-sectional elbow connected to a straight flare gas exit section.
• No pre-mixing of air and flare gas occurs, ensuring the combustion zone has a rich net heating value at the flare gas tip exit.
• Further improves flaring efficiency and reduces steam consumption while meeting the EPA Code of Federal Regulations, Chapter 1, Subchapter C, Part 63, Subpart CC requirements.
