Environmental sustainable

NOx level at 25 ppm in dry gas mode with option down to 15 ppm.

Operational flexibility

The GT36 offers an unmatched operation flexibility in its class: its unique sequential combustion technology allows a high turndown. This enlarges the emission-compliant operation window compared to other combustor technologies and consequently the options for the power plant operator – thus offering a clear advantage in today’s and future power generation markets.

:The GT36 flexibility features include

• Fast start and fast ramp

• High part load efficiency

• High turndown capability with low fuel consumption, providing high reserve power

• High fuel flexibility

• High Hydrogen Capability

High Hydrogen Capability

Due to the high burning velocity and high flame temperature, standard gas turbine combustion technology struggles at high hydrogen content with high NOx emissions and the risk of flashback. This usually results in the necessity of power derating to comply with required standards.

Based on two successive combustion stages, the GT36 recovers the derating of the first stage by shifting the fuel into the second stage. This allows for full operational flexibility, low NOx and no derating.

The GT36 engine represents a future-proof investment, keeping its high efficiency at high hydrogen contents. Currently 70% hydrogen in natural gas blends are released for operation, providing best-in-class hydrogen capability, and the development to 100% is on the way
