High-efficiency sCO₂ Fired Heaters

In a supercritical CO₂ (sCO₂) power cycle, CO₂ circulates in a closed loop at high pressure and drives a compact turbine. The turbine has no combustor, so a fired heater supplies the heat, burning natural gas to heat the CO₂ before it reaches the turbine. At pressures above 2,500 psi and outlet temperatures of 550 to 600 °C or higher, the design comes down to tube metal temperature, alloy selection, pressure drop and flame clearance. FIS solves the same problems in refinery heaters.

What We Offer

• Rated for your required duty, turndown and efficiency, from pilot units to multi-megawatt commercial heaters

• Designed to your cycle's inlet and outlet temperatures, pressures, flow and allowable pressure drop

• Coil alloys (austenitic stainless or nickel alloys) and wall thicknesses selected per API 530

• Modular, shop-fabricated construction that cuts field work

• Containerized option that ships in standard 40-ft containers

Why FIS

• 30 years designing and revamping refinery fired heaters, much larger than a typical sCO₂ unit

• Established relationships with tube mills, burner and fan manufacturers, and qualified fabricators

• US fabrication for the shortest schedule, or overseas fabrication when cost matters

• FIS manages design, procurement, inspection and shipping
