Gas Turbine Emissions Mapping
De-mystifying complexity: the gas turbine mapping expert course.
Modern DLE combustion systems look daunting: five distinct gas circuits, bounded by narrow dynamics corridors and moving ambient targets. This course takes you from zero gas-turbine knowledge to confident field mapper over four days, taught by a practitioner with 19+ years of live mapping experience and multiple patents in the field.
The 4-Day Arc
Combustion & Gas Turbine Fundamentals
The physics you need before you can tune anything: how flames behave, what sets flame temperature and NOx, and how a DLE machine is actually built, from premixer to metering valve.
- Premixed, diffusion and partially-premixed flames, and why DLE chose premixed
- Equivalence ratio φ, the lean operating window, and adiabatic flame temperature
- Thermal NOx (Zeldovich) and its exponential sensitivity to flame temperature
- Laminar flame speed compared: methane, heavier hydrocarbons, hydrogen
- Flashback, lean blowout and flame lift-off: mechanisms, precursors, protection
- Brayton cycle, gas turbine architectures, and DLE vs diffusion (SAC) philosophy
- Hardware: swirler, premixer, liner, transition piece, fuel nozzle
- Fuel supply chain: staging valves, metering valves and the float circuit
- Classify any flame and predict its temperature, NOx and stability signature
- Read a fuel-composition change and infer the flashback and NOx consequence
- Say what each valve and sensor does, and what happens in the combustor when it degrades
Combustion Dynamics & DLE Operation
Why premixed flames sing, what the amplitude limits actually oblige you to do, and how a combustion system is staged and controlled.
- Thermoacoustic instability and the Rayleigh criterion: when an oscillation grows
- LFD and HFD amplitude bands, and the action each band requires
- Protection hierarchy: E-ABAL → BRNUL → stage down → trip
- High-cycle fatigue: what dynamics does to hardware, and how fast
- Dynamic pressure sensors, sampling rate, signal processing and damping
- Combustion system fuel circuits, burner modes and mode-transition risks
- The key limiting tones: where each appears and the correct first action
- Fuel orifices: what they fix, how they are identified, when to swap
- Control schedules, operating-window boundaries and remapping triggers
- Decide from a described oscillation whether it will grow or decay
- Place a measured amplitude in the right band and take the right protective action
- Move pilot split, ELBO and TFlame the correct direction, and state the NOx cost
Emissions, CEMS & Combustion Mapping
Where NOx and CO come from, how they are legally measured, and then mapping itself — carried end to end on both aeroderivative and heavy-duty machines, with the procedure worked step by step on a simulated combustion system.
- NOx pathways (thermal, prompt, fuel-bound, N₂O); CO formation, quench and LBO proximity
- Extractive vs in-situ CEMS, and the EPA Method 7E sampling train
- Analyzers compared: CLD, NDIR and O₂ cells; probe siting and heated sample lines
- Calibration drift against the ±2.5%-of-span limit, and emissions data QA
- Regulatory corrections: 15% O₂, dry basis, ISO conditions
- What a mapping campaign has to deliver, and how that differs between the two machine classes
- Aeroderivative combustion: ring staging, staging valves, and the valve-by-valve mode change
- The combustor modes, the power band of each, and the hand-over where two modes overlap
- Bleed control, reference schedules against compressor discharge temperature, and where bulk demand sits inside the window
- The two walls of the operating window, the five mapping points, and the order the adjustments are made
- Sweeping one adjustment cleanly, carrying a campaign mode by mode, then writing bias into tables and verifying the hand-over
- A real field mapping log read row by row: what each adjustment did, and where the walls turned out to be
- Heavy-duty mapping on the simulator HMI: per-circuit emissions and acoustics response
- IGV settings versus load, and part-load CO
- Mapping preparation, safety protocols, tools, and the step-by-step procedure
- Cold-tune / hot-check discipline across fuel temperature
- Updating fuel circuits mapping tables, plus the remote tuning bias table
- Operating-line verification and mapping documentation requirements
- Correct raw analyzer readings to 15% O₂ dry, and judge a daily drift check
- Run a full mapping sequence on the simulated combustion system, inside the mapping window
- Plan and carry a mode-by-mode mapping campaign, and read a real field mapping log
- Produce as-left mapping tables and release an engine with the right evidence behind it
Ambient, Flex Fuel & Troubleshooting
What moves your map after you have set it (weather, fuel and failing instruments), and how to tell a real combustion event from a sensor lying to you.
- Inlet temperature, pressure, humidity and altitude effects on NOx, stability and output
- Ambient correction strategies and seasonal remapping
- Wobbe Index and Modified Wobbe Index: the ±3% alarm, ±5% action and ±10% trip bands
- Acoustic response to fuel-composition change, and measurement time delay
- Hydrogen blending: flame speed, flame position, convective delay and flashback risk
- Sensor failures (dynamic pressure, thermocouple and emissions) and their signatures
- Acoustic spikes, system freeze, wrong-circuit wiring, and calibration error propagation
- Root-cause analysis for LBO, flashback and stage-down events
- Field case studies: LBO during load rejection, and a commissioning wiring error
- Course review, operational best practices, and the common pitfalls to avoid
- State which way NOx, stability and power move for any ambient change
- Decide whether a fuel change needs a schedule correction, a remap, or hardware
- Separate a failing sensor from a genuine combustion event in unit data

Certificate of Verified Competency
Instructor examined · $300The credential a hiring manager can trust. After the course, you sit an advanced written examination and then a 60-minute live, one-on-one oral examination with the instructor: questions without notice, design cases not covered in the material, reasoning out loud. A pass issues a certificate signed by the instructor, attesting that you were examined in person and demonstrated a verified command of every key principle of the subject, each one listed on the certificate.
- Prerequisite: the Certificate of Completion
- Advanced written examination at analysis level, 80% pass mark
- 60-minute oral examination by video, scheduled around your time zone
- Signed and issued only by the instructor after the examination
- One complimentary re-examination if mastery is not shown the first time
The examined tier is opened for each course once its first learners complete; ask us if you would like it for this course.
