Fuel flexibility

A single-chamber, full-scale test campaign was conducted on DLN1 hardware to assess the combustor’s capability to operate with increasing C2+ levels in the fuel gas. Standard hardware currently installed on Frame 5/1PA DLN1 units are suitable to burn fuel gases with up to 40% C2+ (C2 to C4 alkanes) with no issues for the combustor’s operability or integrity.

Frame51PA Fuel Flexibility


Fuel composition

The Frame 5/1PA DLN1 can burn heavy hydrocarbons (25% max ethane content or 20% max propane), inerts (25% max CO2 or 25% max N2), hydrogen up to 20%, liquid fuel (distillate #2 at 42 ppm wet).

Performance enhancement

Maintenance plan enhancement (35,000/70,000 hours) can be provided as an option on the standard/LHE configuration.
