Invite 3: Laminar Flame Speed Measurements of Ammonia Blended with Dimethyl Ether

The energy sector’s decarbonization is a complex process and includes different approaches aiming for the stepwise movement to a low carbon mobility future. Ammonia as an alternative fuel is considered essential to this transition as an energy carrier, a carbon-free molecule with high energy density, and its production and distribution infrastructure is well-established. With the traditional NH3 production, green ammonia production highlights the importance of further development to implement ammonia as a building block in the global low-carbon energy landscape. However, the low reactivity of ammonia hinders its application for power generation. Therefore, one feasible way to boost the reactivity of ammonia is to go for a dual-fuel system by adding combustion promoters. Thus, the combustion properties of ammonia were investigated by blending it with various proportions of dimethyl ether (DME), where a constant volume spherical reactor (CVSR) was used to measure the laminar burning velocity. DME is a reactive fuel produced in the sustainable carbon cycle reaching a net zero-carbon emission. To this end, my talk will focus on the laminar flame speed of NH3/DME blends.
