Ammonia-Hydrogen Combustion in Micro Gas Turbines

Awarded: NOK 2.5 mill.

The project ADONIS aims to enable ammonia utilization in MGT for distributed carbon- free power generation. The project will produce a state-of-the-art assessment of the MGT cycle performance (WP1) underpinned by three constitutive building blocks that address three important open questions of fundamental scientific nature. These are: flame-wall interaction in ammonia/hydrogen flames (WP2), thermoacoustic characteristics of ammonia/hydrogen flames of (WP3) and fuel injection optimization, mixture preparation and ignition (WP4). WP1. Design and optimization, using thermodynamic cycle and CFD simulations, of a generic MGT fueled with ammonia, both for power generation as well as for a cogeneration configuration (SUT). The combustion chamber geometry will be selected based on existing gas turbine designs available from the open literature (e.g. Turbec T100). WP2. Advancement of basic scientific knowledge in the field of laminar and turbulent near-wall reactive flows deploying both state-of-the-art experimental measurements (AIST/UT) and numerical modelling (SINTEF) building upon previous work on the topic of flame-wall interactions in Japan and Norway. WP3. The thermoacoustic characteristics of ammonia-hydrogen flames is investigated aiming to close the currently existing knowledge gap. Low-order models that are able to represent the flame response to acoustic disturbances will be created (ZHAW) based on numerical simulations (SINTEF) and laboratory experiments (AIST). WP4. The first task of WP4 will concern the realization of an experimental database that characterizes liquid ammonia sprays and subsequent vaporization at different conditions (U Orleans). The second part of the WP aims at using CONVERGETM RANS or/and LES computations in MGT configurations to assess the impact of ammonia vaporization on the combustion process (IFP).
