With experienced in-house engineering & design, we bring complete end-to-end solutions as your one-stop shop for noise and air emissions control.
We provide noise and air emissions control and waste heat recovery systems for power generation, oil and gas, petrochemical and other industrial sites worldwide.
A gas turbine bypass system diverts flue gases from the Heat Recovery Steam Generator (HRSG) in combined cycle mode to a bypass stack with a silencer assembly to operate in simple cycle mode. Maintenance can then be performed on the HRSG as the diverter isolates it completely from the gas turbine.
Another use of the bypass diverter system allows for combined cycle operation during the day and simple cycle operation at night when power demand is lowest. Additionally, the diverter permits power to be generated by the gas turbine even when the steam turbine cycle is down for a scheduled or unscheduled shut down.
ATCO has engineered, fabricated and installed gas turbine bypass systems in as diverse places as South America, MENA and Northern Canada.
We can create reliable, robust and effective designs to meet any system and compliance requirements, as we take into account such critical areas as:
Engineering Innovation
A traditional problem with diverter dampers are the “hot spots” at the seal land area, which result in issues with personnel safety as well as diverter damper functionality. ATCO Emissions Management has created a patented seal land system that solves the “hot spot” issue, resulting in a more robust and cost-saving system.
ATCO uses in-house CFD and 3D modeling, as well as finite element analysis to ensure that all design limits for pressure drop, local velocity limits in critical silencer sections, and non-cyclonic flow requirements are met.
Customizable Diverter Damper Options
We offer comprehensive gas turbine services, starting with an evaluation of your needs, in order to design the most energy and cost efficient bypass system to meet your safety specifications.
Our diverter damper options include:
Fully actuated diverter dampers:
Tee box with blanking plates:
Tee box with retrofit capability:
For guaranteed noise compliance, we offer our Higgott-Kane™ Gas Turbine silencing systems in bypass mode by carefully fine-tuning system geometry to reduce turbulence and the noise associated with it.
