Combustion Liner Wheeling

Gas Turbine Combustion Liner Wheeling Repair

Our Expert Team Will Establish Accurate Flow Rates and Match Gas Turbine Combustion Components

Our Combustion Liner Wheeling Services includes analysis of the combustor flame temperature spread (can-to-can), which is determined by variation in the fuel and airflow rates within each combustor assembly.

To maintain gas turbine service performance and to minimize the risk of damage to hardware, it is important to establish accurate flow rates and match combustion components to regulate performance.

Fuel Flow Measurement

EthosEnergy encourages the best practice of calibrating or ‘wheeling’ combustor fuel nozzle assemblies. This technique ensures fuel-metering components are accurately measured and configured in order to minimize variation in fuel flow rates across the combustion system.

Accurate calibration ensures the combustion system is able to deal with changing environmental conditions and mitigates the risk of emission excursions.

Air Flow Regulation

Determining combustor airflow is more difficult than determining fuel flow. This is due to the large effective area of the liner relative to the effective area of the fuel system.

EthosEnergy has developed a flow stand that is capable of flowing combustion liners for calibrating or ‘wheeling’ purposes.

Optimized Combustor Performance

Wheeling of a DLN-1 system involves grouping ‘high’ flowing primary parts with ‘low’ flowing secondary parts to ensure that fuel flows are as uniform as possible.

Finally, each set of primary and secondary nozzles are assigned to a specific and calibrated liner. This process minimizes variation in flame temperature spread, enhancing the performance and efficiency of your combustion system.
