Clear the line. Protect the turbine
Power availability increasingly determines where hyperscalers can build data centers. To eliminate grid dependency and ensure reliable capacity, many are now constructing power plants within their facility perimeters—behind the fence line. This strategic shift demands pre-commissioning solutions that match the urgency and scale of data center operations.
FQE Power delivers OEM-approved, patented SigmaCommissioning services specifically engineered for behind-the-fence power generation. Our integrated approach collapses traditional cleaning phases with startup processes, dramatically reducing schedule risk while minimizing consumption of costly resources like fuel and boiler feedwater.
What SigmaCommissioning Removes
Our patented processes eliminate the contaminants that threaten turbine integrity and system performance:
- Large debris from construction and fabrication
- Rust and millscale that can damage turbine blades
- Construction and fabrication grease that compromises system cleanliness
- Creates passivation coatings to protect internal surfaces
All accomplished by leveraging permanent plant equipment to minimize temporary equipment footprint, site provisions, and logistical complexity.
- SigmaBlows: Our cutting-edge steam blowing process delivers target cleanliness requirements faster while consuming significantly less fuel and water than conventional methods. The technology minimizes temporary equipment requirements and proves exceptionally efficient on power systems with reheat circuits—where traditional steam blows demand extensive additional temporary piping that adds cost, complexity, and schedule risk.
- Technical advantage: Generates the highest kinetic forces and cleaning flow ratios (CFR) available within OEM specifications, ensuring thorough removal of particulate matter that could damage downstream turbine components.
- SigmaClean: HRSG pre-commissioning treatment that simultaneously degreases internal surfaces and forms protective magnetic oxide layers in preparation for startup. This technique was specifically designed to reduce overall cleaning requirements and eliminate the need for hazardous chemical cleaning processes—delivering substantial cost savings while maintaining or exceeding stringent final cleanliness standards.
- Technical advantage: Uses operational chemistry to passivate steel surfaces, creating magnetite layers that protect against corrosion while testing boiler feed pumps to full load conditions and removes oxygen residuals weeks ahead of first fire.
- Sigma Solve: A sequential cleaning process engineered to remove organic components followed by corrosion products, then apply a passivation layer to ensure efficient, protected startup. This comprehensive approach addresses multiple contamination types in a single integrated procedure.
- Sigma Dry: An advanced evolution of conventional air blow processes. Unlike traditional “blast and hope” methods that cannot remove millscale, Sigma Dry™ employs enhanced techniques to achieve superior cleanliness levels in systems where steam blowing is not applicable.
