Syngas combustor for gas turbine application

Since 2004 Innecs B.V. is active in the field of energy conversion, using combinations of innovative technologies in order to gain economic perspective, while saving the environment.

Cooperation with Universities

Innovation, in our view, embodies a permanent effort in applying the latest ideas and know-how to find new concepts and solutions. That is reason Innecs works in close cooperation with Universities on numerous subjects. Fields of interest include combustion, electric power conversion, gas and steam turbine technology. Many students have found interesting and challenging subjects for internships and graduation theses.

The assigned tasks usually offer a combination of theoretical and experimental work. For test purposes, Innecs explores a number of unique facilities in which new concepts can be researched.

Origin of the subject:

Innecs is currently heavily involved with endurance and reliability testing of a newly designed gas turbine, called the PowerBurner. The PowerBurner generates about 1700kW thermal power and 250kW electrical power and is an interesting proposition for cogeneration in the midsized industry. The PowerBurner is equipped with the FlexBurner which has recently been developed in cooperation with University of Twente. The FlexBurner is a multi-fuel combustor which is able to combust standard natural gas and medium calorific biogas. Questions arise from the market to develop low calorific combustor.

At the Thermal Engineering group of University of Twente, a burner was developed to combust low calorific gas mainly consisting of H2, CO and N2, the so-called syngas. This HEGSA burner has a thermal power output of 20kW per bar and has to be scaled to meet the PowerBurner specifications of 2MW. By combining the FlexBurner and the HEGSA burner technologies, it’s possible to realize a syngas burner for gas turbine application.


Design a burner and combustion chamber based on the HEGSA and FlexBurner which combusts low calorific syngas. Perform CFD calculations to optimize the design and minimize (NOx) emissions. Verify and compare the results by experiments.
