- Major Design Concern;

a) Short Distance Available to Mix the Air

b) Conflicting requirement at the inlet duct

Mix the air into flue gas (Turbulence)

versus

Uniform gas flow necessary at CO catalyst face.

versus

Homogeneous ammonia mix in flue gas at SCR catalyst face

(Flow Straightening & Velocity Normalizing at Catalyst)

• Double entry tempering air ensures uniform air injection into duct

• Equally staged nozzles discharge across turbine exhaust cross section

• Directional nozzles allows tempering air penetration in high velocity zones

• High strength retaining structure construction ensures reliable performance

• All stainless steel design ensures mechanical integrity in high temperature zone

MANIFOLD

• Double entry balancing valves manifold to bias AIG

• Lance panels allows expedient optimization

• High density drilling, dense ammonia injection pattern

• Orifice flow measurements validate ammonia panel flow field balance

• Allows for future optimizing as catalyst ages or turbine performance degrades

“…..Frame combustion turbine can be and has been successfully coupled with SCR to

meet strict environmental standards. These two mature, proven technologies – frame-type

combustion turbines and SCR systems – are not inherently incompatible or infeasible to

combine, but do require proper design and engineering…..

• Frame technology and SCR emission control systems are both proven technologies.

• The Marsh Landing Generating Station (MLGS) comprised of four F-Class turbines that

began operation in March 2013, has achieved its performance requirements, including

emission limits, using an SCR with an air tempering system designed by Mitsubishi.

• Recent advances in SCR design and catalyst formulation, along with commercial

experience, have eliminated any engineering basis for distinguishing between Aero-

derivative and frame-type combustion turbines in terms of the economic viability of

using SCR to comply with strict environmental limits…..”
