100% hydrogen dry low NOx combustor developments for 2MW class gas turbine
The Proceedings of the International Conference on Power Engineering (ICOPE), vol. 2021.15, pp. 2021–0222
Abstract
Kawasaki Heavy Industries, LTD. (KHI) has research and development projects for a future hydrogen society. Within the development of the hydrogen gas turbine, the key technology is stable and low NOx hydrogen combustion, namely the Dry Low NOx (DLN) hydrogen combustion. KHI, Aachen University of Applied Science, and B&B-AGEMA have investigated the possibility of low NOx micro-mix (MMX) hydrogen combustion and its application to an industrial gas turbine combustor. From 2014 to 2018, KHI developed a DLN hydrogen combustor for a 2MW class industrial gas turbine with the micro-mix technology. Thereby, the ignition performance, the flame stability for equivalent rotational speed, and higher load conditions were investigated. NOx emission values were kept about half of the Air Pollution Control Law in Japan: 84ppm (O2-15%). And this new hydrogen DLN micro-mix combustor was installed and demonstrated in the 1MW class hydrogen fuel gas turbine co-generation plant. In 2020, engine demonstration was successfully conducted without any issues in combustor parts, like flashback and strong combustion oscillation. And NOx emissions values were kept below Air Pollution Control Act. Japan and engine efficiency was 1% improved from conventional diffusion flame combustor with water injection NOx reduction system.
