In a virtuous pursuit to reduce harmful emissions for the people and the Planet, and to tackle climate change, EU is to revise the Industrial Emissions Directive (IED) over the course of 2022.

In North America the regulation on air emissions is considered a dynamic goal, which changes with technological progress according to the principle of Best Available Technology (BAT).

In the effort to provide easy-to-operate solutions for the above targets, Baker Hughes developed for the NovaLT family of industrial gas turbines an enhanced gas turbine combustor, able to achieve ultra-low NOx and CO emissions with a Dry Low NOx (DLN) technology.

The present paper describes the validation test of a new generation of ultra-low DLN combustor conducted in Baker Hughes factory on a complete NovaLT16 gas turbine unit and control system, providing details about the product development process, the test bench design, the instrumentation and verification activities, the test execution, and the relevant validation outcomes.

The test described in this paper took place in Nov 2021 at Baker Hughes facilities in Firenze, Italy, as part of the verification and validation activities for the development of the Single Digit new configuration of the NovaLT16 gas turbine.
