Gas Turbine Exhaust

Cleaner burning than other fossil fuels, the combustion of natural gas produces negligible amounts of sulfur, mercury, and particulates. However, natural gas does produce nitrogen oxides (NOx), which contributes to smog.

CECO provides a wide range of technologies to enable air and noise emissions management in gas-fired power plants. These systems may be supplied on a turn-key basis supported by in-house engineering, project management, and on-site installation supervision.

Where multiple technologies are required, it is often preferable to design a fully-integrated, custom system, rather than to buy and bolt-on individual pieces of equipment from multiple manufacturers. Accordingly, integrated gas turbine exhaust solutions involve various combinations of clean, safe and efficient technologies, which are custom-designed, commissioned and integrated seamlessly for maximum performance.

CECO’s Aarding, Burgess-Aarding, Peerless, Effox-Flextor, and CCA brand products and solutions below fit within the classification of Integrated Gas Turbine Exhaust:

Gas Turbine Exhaust Systems


De-NOx Solutions 

Solutions designed to reduce nitrogen oxide (NOx) emissions include SCR and SNCR. SCR (Selective Catalytic Reduction) is a means of converting NOx with the aid of a catalyst into diatomic nitrogen (N2), and water (H2O). In contrast, with SNCR (Selective Non-Catalytic Reduction), either ammonia or urea is injected into the boiler to react with the nitrogen oxides formed in the combustion process. The resulting product of the chemical reaction is diatomic nitrogen, water, and carbon dioxide (CO2).



Dampers redirect the flow of hot gas from one outlet to another. They modulate gas flow, divert gas flow, and isolate equipment from gas flow.


Expansion Joints

Expansion Joints are designed to safely absorb the heat-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement:



Industrial silencers are used to control the noise associated with a wide range of industrial processes.


Power Industry Separators 

Pressure vessels used for separating a well stream into gaseous and liquid components.
