Abstract

<p>Kawasaki Heavy Industries, LTD. (KHI) has been conducted research and development projects for a future hydrogen society. Within the development of the hydrogen gas turbine, key aspects are stable and low NOx combustion. KHI developed a Dry Low NOx (DLN) hydrogen combustor for a 2MW class industrial gas turbine with the micro-mix technology. Thereby, the ignition performance, the flame stability at engine start-up and loading conditions were investigated. NOx emission values were kept about half of the Air Pollution Control Law in Japan (70ppmv@16% O2). In 2020, KHI started the engine demonstration operation by using an M1A-17 gas turbine with a co-generation system located in the hydrogen-fueled power generation plant in Kobe City, Japan. Finally, at a power output of 1800kW, the NOx emissions were 60 ppm (O2-16%, 60% RH). For the first time, a DLN hydrogen-fueled gas turbine successfully generated electricity and heat.</p>
